https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192315 Alexander Motin <mav@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mav@FreeBSD.org --- Comment #1 from Alexander Motin <mav@FreeBSD.org> --- Line "Event timer "LAPIC" quality 400" in verbose dmesg tells that LAPIC timer in your CPU (used by default) is not compatible with CPU C-states (deep idle states). Can you make sure that C-states are not used on your system by checking 'sysctl dev.cpu | grep cx_usage' and 'sysctl -a | grep cx_lowest'? Timer code was not changing for quite some time already, while C-states were enabled by default less time ago, IIRC. -- You are receiving this mail because: You are the assignee for the bug.
