For instance - ping will only send a ping every 2 seconds instead of every second. systat -vmstat 1 refreshes every 2 seconds, etc. Disabling APIC 'fixes' it. - Every 6 seconds, my system pauses (clock on taskbar stops, mouse movement stops, keys pressed pause, etc) - but comes right back in a slightly accelerated pace until it catches up with real time, then it's good for another ~6 seconds until it happens again. This had the side effect of causing powerd to ramp my cpu all the way up every 6 seconds (cpu would drop, pause would happen, pause completes, system is backlogged, so powerd ramps cpu to 100%, etc). I don't think it's an interrupt storm, but running systat -vmstat 1 (refreshing every 2 seconds) seems to show me the time is spent in 'sys'. My system info (and lots of history) is available here: http://www.googlebit.com/freebsd/ Eric -- ------------------------------------------------------------------------ Eric Anderson Sr. Systems Administrator Centaur Technology Anything that works is better than anything that doesn't. ------------------------------------------------------------------------
