You can unload the usb modules (uhci_hcd) if they are compiled as modules to keep them from generating any interrupts. But I suspect that most of these wakeups are caused by your cx88 capture cards. Were they capturing at the time? > 8.3% ( 20.0) mythbackend : futex_wait (hrtimer_wakeup) MythTV is also a big offender. But luckily you aren't running mythfrontend or mythwelcome, they generate a 1-2 hundred wakeups each. mythbackend also wakes up 100 times a second for me, so you are actually doing well, there! What version of MythTV? -Dave _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
