Stopped.
Found new dashboard test flakes for:
#!watchflakes
post <- pkg == "runtime" && test == "TestSpuriousWakeupsNeverHangSemasleep"
Judging by the rate of failure, this doesn't seem particularly critical, but we should probably make the test less flaky in general. This seems like a scheduler test that should just be made less flaky, or disabled.
FYI I was able to recreate this on amd64 Linux. I ran go test -test.run=TestSpuriousWakeupsNeverHangSemasleep -test.count=1000 runtime
panic: test timed out after 10m0s
