Powertop tells me:
Top causes for wakeups:
34.3% (100.0) mythbackend : do_nanosleep (hrtimer_wakeup)
31.8% ( 92.8) kdvb-ca-0:0 : schedule_timeout (process_timeout)
17.6% ( 51.2) <interrupt> : saa7146 (0), via at pci:0000:01:00.0
5.8% ( 17.0) mythbackend : schedule_timeout (process_timeout)
3.4% ( 10.0) at-spi-registry : schedule_timeout (process_timeout)
3.4% ( 10.0) Xorg : do_setitimer (it_real_fn)
0.7% ( 2.0) <kernel core> : clockksource_register(clocksource
(etc)
So mythtv is causing a lot of wakeups.
How can I tweak this?
I don't have a chipcard attached to my ca-slot, so I can go without the
kdvb-ca-etc; how can I fix this?
Any ideas?
Udo
