Sorry for delay.
Finding out what its doing is the first step.
1- is it stuck in userspace? (top)
Nope, the CPU is idle (load of <3%)
2- is the kernel really busy? (boot with profile=1, and run
readprofile, or
use oprofile)
Attaching readprofile logs, which were taken by:
readprofile -r; sleep 1000; readprofile > log
The logs are:
log_plugged - laptop running on AC power, no problems
log_unplugged - laptop running on batteries, fan runs wildly wasting the
battery power reserves
3- does /proc/interrupts show an interrupt arriving at a ridiculously
high rate?
/proc/interrupts shows nothing suspicious, only timer and LOC increasing
in the normal increment
