alexcrichton opened PR #11858 from alexcrichton:s390x-qemu to bytecodealliance:main:

This commit moves away from s390x runners provided by IBM back to github actions runners with QEMU emulation. Watching the queue today it looks like PRs are spending quite a lot of time waiting for runners to become available to execute jobs on. Looking at the data for the past week jobs are frequently queuing for 10+ minutes before being able to run. Given that our CI completes in ~15 minutes that more-or-less defeats the purpose of the native runners, so this commit switches back to github actions for now which should resolve the queueing issues.
