It also causes a lot of wakeups (infact, one among the top 5 processes doing that). Top causes for wakeups: 50.5% ( 58.4) <interrupt> : uhci_hcd:usb1, yenta, eth0 8.5% ( 9.8) <interrupt> : i8042 6.1% ( 7.1) <interrupt> : libata 4.3% ( 5.0) <interrupt> : irda0 4.3% ( 5.0) tpb : do_nanosleep (hrtimer_wakeup) 3.4% ( 3.9) <kernel module> : usb_hcd_poll_rh_status (rh_timer_func) Top causes for wakeups: 16.0% ( 7.5) <interrupt> : irda0 10.6% ( 5.0) tpb : do_nanosleep (hrtimer_wakeup) 8.5% ( 4.0) <kernel module> : usb_hcd_poll_rh_status (rh_timer_func) 7.4% ( 3.5) <interrupt> : extra timer interrupt 6.4% ( 3.0) powersaved : queue_delayed_work_on (delayed_work_timer_fn) Top causes for wakeups: 53.2% ( 72.9) <interrupt> : uhci_hcd:usb1, yenta, eth0 9.7% ( 13.4) <interrupt> : i8042 9.7% ( 13.4) elinks : schedule_timeout (process_timeout) 3.6% ( 5.0) tpb : do_nanosleep (hrtimer_wakeup) 3.0% ( 4.1) <interrupt> : irda0 Giridhar -- Y Giridhar Appaji Nag | http://www.appaji.net/
