https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276967 --- Comment #3 from Mark Johnston <markj@FreeBSD.org> --- (In reply to Thomas Steen Rasmussen / Tykling from comment #2) Yes, this is what I was looking for, but it's a symptom of the problem rather than the root cause. In particular, a thread is waiting to run on a particular CPU (in order to read hwpstate MSRs) but is not getting scheduled. It would be useful to see the full procstat output. Then we can see what else is on-CPU. -- You are receiving this mail because: You are the assignee for the bug.home | help
