This looks like a deadlock, and I would be surprised if it did not also affect at least other linux platforms in some cases.

I would be surprised if it did not also affect at least other linux platforms in some cases.

Indeed, there it is — linux/amd64 and netbsd/arm64 have no elements in common. 😅

Given the number of very recent failures reported, I suspect that this was introduced in CL 448155.

@neild, @heschi, @bradfitz: given that this landed during the freeze and http2 is bundled into the main repo, does this need attention before the Go 1.20 release?

Looks like this hasn't been pulled into the main repo yet, so this doesn't need to be a release blocker for 1.20 unless we're planning to refresh the x dependencies one more time before the final release. (@golang/release can confirm whether that is the case?)

But it will presumably need to be resolved before we can update x/net for the 1.21 cycle, so marking as release-blocker for 1.21.

unless we're planning to refresh the x dependencies one more time before the final release. (@golang/release can confirm whether that is the case?)

We create internal vendor branches for x repos at the time of cutting RC 1 (see #11811 (comment)), and after that point we've generally been adding to that branch only the CLs that are necessary to fix release-blocking issues for the given release. So the 1.21 milestone seems okay to start out with here.
