[Bug 268897] panic: [pmc,4811] Retrieving callchain for thread that doesn't want it

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268897 --- Comment #6 from John F. Carr <email@example.com> --- The multithreaded angle is a red herring. You don't need the program I attached. On an ordinary desktop class Zen processor ("Ryzen 5 PRO 2400GE") running CURRENT I ran $ pmcstat -U -P instructions echo -n and the kernel crashed the same way. You do need to get root to kldload hwpmc so it's not quite as bad as it sounds. -- You are receiving this mail because: You are the assignee for the bug.
