From linux-ppc64-buildlet (https://build.golang.org/log/620feae79d01758bdc246133f337e735aa269837), a timeout with lots of blocked tests and the running goroutine obscured:

[…]
goroutine 2 [running]:
	goroutine running on other thread; stack unavailable
created by runtime.init.4
	/tmp/workdir-host-linux-ppc64-osu/go/src/runtime/proc.go:242 +0x34
[…]
*** Test killed with quit: ran too long (6m0s).
FAIL	runtime	360.006s

@bradfitz
env/linux-ppc64/osuosl: upgrade linux/ppc64 hardware & OS, use Docker
b1a7aa2 
Collaboration with @tiborvass at Docker who got Docker running on
big-endian PPC64. Go for ppc64 doesn't support cgo or external
linking, so runc doesn't work, but a new OCI-compliant runc
implementation written in C (https://github.com/containers/crun) means
we can run Docker after all. See NOTES & build-*.sh

Then add a Dockerfile & associated cleanup in buildlet & stage0 to use
rundockerbuildlet.

Once done, might help with golang/go#35188, golang/go#32613, etc.

Fixes golang/go#34830
Updates golang/go#21260

I don't see the deadlocks for a while. Looks like it's gone.

Thanks, closing. We've fixed several potentially deadlock causing bugs in the last few weeks.
