Eric Sandeen wrote: On what kernel? 2.6.26.0 (haven't rebooted to 2.6.26.5 yet) As far as the wakeups go, I thought this was fixed; see for example: TAKE 977545 - xfsaild causing too many wakeups --- It may be fixed in a newer kernel...(referring to David's later comment).. Just looked at it with powertop 1.10: Wakeups-from-idle per second : 7.1 interval: 10.0s Top causes for wakeups: 42.9% ( 6.0) xfsaild : schedule_timeout (process_timeout) 14.3% ( 2.0) <kernel core> : clocksource_register (clocksource_watchdog) 8.6% ( 1.2) xfsbufd : schedule_timeout (process_timeout) 7.1% ( 1.0) ip : tg3_open (tg3_timer) |
