Mostly #51001. (Perhaps that issue accounts for all of them?)

#50144 and #51001.

I've updated those with watchflakes patterns. (@rsc / @cherrymui — could you double-check that the patterns match?)

I don't see where this log is coming from. I don't see it on the build dashboard on that date and I don't see the commit mentioned in the git log for the latest master.

I left a comment at #57367 (comment).

(That particular was a compiler regression that was subsequently reverted.)

In triage, I don't see anything new to break out here? Leaving this comment as a marker for next time.

These are the same failures as in #60368. They started when the compiler
was built with PGO.

The problem I mentioned earlier was fixed by https://go-review.googlesource.com/c/go/+/499679 which for some reason became apparent when PGO was used to build the compiler. This problem affected all ppc64/ppc64le ports since it was bug in the ppc64 version of the gc write barrier flush and resulted in several different stack traces from the compile step. We've not seen that particular problem since.
