Hi all!
I wonder what all those "schedule_timeout (process_timeout)" mean.
Are they related to "29.2% ( 67.2) <kernel IPI> : Rescheduling
interrupts"?
If so how could I get rid of all those schedule related wakeups?
Now I'm using 2.6.24-11.17-generic SMP (2.6.24.3-rt3) on Ubuntu Hardy
beta 5
and get from 200 to over 800 wakeups, when I was using 2.6.23 I had far
less (just around 25)!!
I just cannot understand what an improvement had the new scheduler
actually brought, at least on the power saving side.
I own an Intel Santa Rosa platform.
Thanks!!
