Both on netbsd-arm64-bsiegert so far. 🤔

Looks like it is now happening on other platforms as well.

The darwin-amd64 logs above have a similar symptom, but they were caused by a separate regression (#58068).

As far as I can tell the unexplained failures are still all specific to netbsd-arm64-bsiegert.

Well, that one isn't on netbsd. 😅

@golang/runtime, that last failure is on a first-class port (linux/amd64) — does that affect prioritization on this issue?
