Since this seems to be very specific to the builder, in triage we're wondering if anyone from @golang/s390x could start taking a look. It seems to be failing often enough that bisection should identify the culprit, and then that might just reveal the issue.

@mknyszek @bcmills thank's for bringing this issue to our attention. I am looking into the issue.

srinivas-pokala · 2023-12-15T13:42:18Z

@mknyszek @bcmills We had a look at this issue and we used git bisect to figure out the culprit commit.

Bad Commit Id: de5b418b which introducing failure of TestCrashDumpsAllThreads()
We had a look at the file changes corresponding to the bad commit, we see that there are some changes to signal_unix.go file and we suspect that issue lies with the changes made to this file.
We are further having look at the changes and we will update when we find more about the root cause of the failure.

Extending the total sleep time as in the CL https://go-review.googlesource.com/c/go/+/554615 seems to help avoid the TestCrashDumpsAllThreads failure on s390x, If we continue to get intermittent failures even after this is committed, probably there is a race condition angle in this case too as mentioned in #64752 (comment)
