Seen on the linux-amd64-race builder (https://build.golang.org/log/f3a82ee42bada1d45efcb4e463feab45f9a1198b).

The only running goroutines are marked goroutine running on other thread; stack unavailable, and the runnable goroutines that aren't running all seem to have the same stack:

Those goroutines are just for the timer, they're relatively harmless (generally speaking).

Re: the messages that say goroutine running on other thread; stack unavailable, would it be possible to run tests on the bots with GOTRACEBACK=crash?

IIUC the builders are now running with GOTRACEBACK=crash, so if this issue has shown up again it is probably tracked separately by now. Closing.
