Issue #20810 has been updated by jaruga (Jun Aruga). I sent the following PR to reenable Travis CI including s390x on the rury/ruby master branch. https://github.com/ruby/ruby/pull/11948 ---------------------------------------- Misc #20810: Re-enable s390x CI Builds on Master Branch in Travis CI https://bugs.ruby-lang.org/issues/20810#change-110232 * Author: mayur.jadhav (Mayur Jadhav) * Status: Feedback ---------------------------------------- Description: Currently, the Travis CI has been temporarily disabled on the master branch via Pr(https://github.com/ruby/ruby/pull/11509). However, the s390x builds are successfully running on other branches( ruby_3_3, ruby_3_2) on Travis CI, which were previously experiencing timeouts. The issue has been addressed by the Travis team. Given the significance of multi-architecture support for Ruby, we request that the Travis CI builds be re-enabled on the master branch. please let us know we are more than happy to collaborate to make this happen. Thanks. -- https://bugs.ruby-lang.org/
