On the linux-ppc64le-power9osu builder (https://build.golang.org/log/585e960d0f000d42817bf1b361c8ecbf51d1294d):

--- FAIL: TestSelectStackAdjust (0.02s)
    chan_test.go:723: failed to trigger concurrent GC
FAIL
FAIL	runtime	35.499s

A similar failure consistently occurs on the openbsd-arm builder, but I'm not confident in its results because it still seems to be misconfigured (#25498 (comment)).

See previously #14852.

There's a discussion in #34391 that might be related to this failure. Some intermittent failures on ppc64 and ppc64le appear to be happening due to a problem with signals, and also affects linux/arm.

Almost all the failures seem to happen when running the runtime tests with -test.cpu=1,2,4.
