Issue #20890 has been updated by markus_d (Markus Doits). For reference here is another backtrace from 3 days ago which I found by googling around, so somebody else seems to have the same problem (no further info though): https://pastecode.io/s/t1a3a8yp. Maybe the new MacbookPros are having this problem. I updated to 15.2 beta 3 to see if it fixed it but nope, same problem.

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by markus_d (Markus Doits). Thanks for your fast reply. You're right the reproduction steps are missing, though unfortunately I tried to recreate a minimal example (downloading some files with `net-http`, suspecting it has something to do with network access), but couldn't reproduce it. Maybe it has to be of a certain size for the YJIT. For example my Rails app loads correctly but the panic happens when triggering a request to a controller. And my editor creates the panic when opening multiple files with `ruby-lsp` attached. I will try to find a minimal example for you to reproduce the bug, feel free to wait for it until looking further. In the meantime maybe others having the same problem find this issue. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110604 * Author: markus_d (Markus Doits) * Status: Feedback * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by alanwu (Alan Wu). Status changed from Open to Third Party's Issue Fascinating. Could you please also [report](https://developer.apple.com/bug-reporting/) this to Apple? It's clearly a kernel bug when an userspace applications can reliably cause the kernel to panic. We'll try to look for a workaround, but Apple is in a much better position to make a fix. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110611 * Author: markus_d (Markus Doits) * Status: Third Party's Issue * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: REQUIRED ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by alanwu (Alan Wu).

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by aaronjensen (Aaron Jensen). One more note is that you can still use preload if you disable Rail's enabling of YJIT (`config.yjit = false`). You can still use YJIT if you enable YJIT in `on_worker_boot`. This may point to the problem specifically being enabling YJIT before forking. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110641 * Author: markus_d (Markus Doits) * Status: Third Party's Issue * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by alanwu (Alan Wu).

That said, is there any possibility that this is actually a YJIT or Ruby fork bug somehow?

No. Modern kernels don't allow unprivileged programs like YJIT to crash them, period. If they did we'd have many broken promises like for example, letting a program running in a VM bring down the entire host system. The line in the sand is clear and has been for decades. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110648 * Author: markus_d (Markus Doits) * Status: Third Party's Issue * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by friek (Johan Mulder). PHP developer chiming in here. I ran into the exact same point at which my Mac Mini M4 panicked when running the Psalm code analyser with PHP opcache enabled. With opcache disabled it doesn't panic. As the same is apparently happening to Ruby I believe this is probably a kernel bug. Also tried it on a Mac Mini M1 running the same Sequoia and it doesn't happen there at all. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110652 * Author: markus_d (Markus Doits) * Status: Third Party's Issue * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by maximecb (Maxime Chevalier-Boisvert). If we can clearly show that it's a kernel bug I am sure that we can get Apple to pay attention and fix it. Two important questions: - Can we get a minimal reproduction going? Ideally we would like to know which specific conditions trigger the bug. Ideally we'd have a single-file C program that triggers the bug. - Which specific versions of the kernel is the bug happening on? @aaronjensen you said you can repro this on two M4 machines, can you report your Darwin kernel version and the make and model of the two machines you reproduce this on? We (the YJIT team) don't yet have M4 macs so we'll need some help from people in this thread to come up with a reproduction. ---------------------------------------- Bug #20890: MacOS 15.1, Macbook pro 2024 m4, YJIT: Kernel Panic on network access, works w/o YJIT https://bugs.ruby-lang.org/issues/20890#change-110657 * Author: markus_d (Markus Doits) * Status: Third Party's Issue * Assignee: yjit * ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [arm64-darwin24] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I'm getting the following panic which seems like it happens on network access, but *only when YJIT is enabled*: ``` panic(cpu 15 caller 0xfffffe00509d800c): [SPTM] VIOLATION_ILLEGAL_SPRR_INDEX: sptm_map_page(sptm.c:406) - page_fte(0xfffffde005159750), page_fte->type(0xe), new_sprr_index(0x7), new_pte(0x6001145892ce43), vaddr(0x11c2c8000) Debugger message: panic Memory ID: 0x6 OS release type: User OS version: 24B2083 Kernel version: Darwin Kernel Version 24.1.0: Thu Oct 10 21:06:57 PDT 2024; root:xnu-11215.41.3~3/RELEASE_ARM64_T6041 Fileset Kernelcache UUID: 918FFAAEF5863665571822DC0F4C5BC0 Kernel UUID: 58CD7EDF-BF0B-3375-B9F8-F2484179E8A1 Boot session UUID: CE59B2C1-E45D-47C9-84B7-B6659DA80D25 iBoot version: iBoot-11881.41.5 secure boot?: YES roots installed: 0 Paniclog version: 14 Debug Header address: 0xfffffe002bef5000 Debug Header entry count: 3 TXM load address: 0xfffffe003be74000 TXM UUID: 772CA8A2-ABBC-34D1-8CC3-C295F9A174FE Debug Header kernelcache load address: 0xfffffe004be74000 Debug Header kernelcache UUID: 918FFAAE-F586-3665-5718-22DC0F4C5BC0 SPTM load address: 0xfffffe002be74000 SPTM UUID: 9EF80C6B-0E45-300A-8EC1-8C49E7CA3D3B KernelCache slide: 0x0000000044e70000 KernelCache base: 0xfffffe004be74000 Kernel slide: 0x0000000044e78000 Kernel text base: 0xfffffe004be7c000 Kernel text exec slide: 0x0000000046534000 Kernel text exec base: 0xfffffe004d538000 mach_absolute_time: 0x30d81dc4f Epoch Time: sec usec Boot : 0x67334fd9 0x0001740d Sleep : 0x00000000 0x00000000 Wake : 0x00000000 0x00000000 Calendar: 0x673351f0 0x000386f7 Zone info: Zone map: 0xfffffe161110c000 - 0xfffffe361110c000 .

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/

Issue #20890 has been updated by mattjankowski (Matt Jankowski).

Maybe Apple fixed it?

15.2 Beta 4 release notes has it:

Fixed: Resolved an issue where running Ruby with YJIT enabled causes Mac with M4 chip to kernel panic. (139714575) (FB15774033)

I can reproduce the panic with 100 % success rate by just starting my Rails app and trying to access it. Or by editing a file in neovim which uses some ruby plugins. I compiled ruby w/o YJIT and the panics seem to be gone. `ruby -v` is without YJIT (same revision with YJIT panics). -- https://bugs.ruby-lang.org/
