This is what I get (on 0.10.4, kde 3.5.6, kubuntu feisty): Wakeups-from-idle per second : 524.0 interval: 10.0s Top causes for wakeups: 42.7% (249.5) knode : schedule_timeout (process_timeout) 17.2% (100.6) <interrupt> : eth0 9.8% ( 57.2) firefox-bin : futex_wait (hrtimer_wakeup) As you can see, it's more than firefox, so this is really a grave bug (this is consistent over a period of time, not just a stray incident). BTW, I'd change this from 'wishlist' to 'bug', since it's not a feature, but a power-drain bug. I can confirm this on Debian (0.10.5 w/ KDE 3.5.8): Top causes for wakeups: 22.2% (248.7) knode : schedule_timeout (process_timeout) 11.1% (125.0) USB device 3-2.1 : BCM2045 (Broadcom Corp) 11.0% (123.5) <kernel IPI> : Rescheduling interrupts 10.1% (113.7) <interrupt> : ehci_hcd:usb2, uhci_hcd:usb3, uhci_hcd:usb5 8.5% ( 95.5) wish8.5 : futex_wait (hrtimer_wakeup) Note that it's even more than an active bluetooth mouse. |
