Naturally, it should work. Unfortunately I can't reproduce on my Ryzen 9 5900X. It could be related to this pull request just opened yesterday: https://github.com/freebsd/freebsd-src/pull/2277 At least, the above patch should tell you if the counter is enabled upon loading hwpmc. If so, this could be the BIOS making very unhelpful use of C= PU resources. --=20 You are receiving this mail because: You are the assignee for the bug.=
