Product: Base System Version: CURRENT Hardware: arm64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: trasz@FreeBSD.org On aarch64, Linux golang test suite hangs at various moments, usually start= ing with the closure4.go test. All of those hangs end up in binary in running state, with two threads. In some cases it doesn't happen to the test case itself, but to the golang compiler. I'm no longer observing the futex erro= rs which were reported by the same test suite on same aarch64 machine before; = my guess is there might be some kind of race condition in recently added aarch= 64 Linuxulator futex support? On amd64 the problem doesn't seem to occur. --=20 You are receiving this mail because: You are the assignee for the bug.=
