https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D235031 Eugene Grosbein <eugen@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |eugen@freebsd.org --- Comment #5 from Eugene Grosbein <eugen@freebsd.org> --- The problem may be related to interrupt handling and/or timekeeping. 1) Do you run ntpd there? If yes, show contents of /var/db/ntpd.drift. If n= ot, start it, make sure it synced time successfully (ntpq -np), wait an hour and show /var/db/ntpd.drift. 2) Show output of sysctl kern.timecounter and sysctl kern.eventtimer comman= ds. If kern.eventtimer.periodic is 0, set it to 1 and repeat your tests and post results. 3) Show output of "grep irq /var/run/dmesg.boot" for 12.0 and use 11.2 live boot media (flash stick or CD/DVD) and repeat "grep irq /var/run/dmesg.boot= ", save output and post it too. --=20 You are receiving this mail because: You are the assignee for the bug.=
