Hmm no that wasn't it..when I switched to poll-mode however, it worked.

if your system is idle, C0 residency should < 10%.
Here C0 = 32.7%, there must be a workload on the system.
Wakeups-from-idle per second: 1156.3 interval: 5.2s
Power usage (ACPI estimate): 2.737W (discharging: 0.6 hours)
Top causes for wakeups:
19.3% (223.2) <kernel> : genunix`cv_wakeup
8.6% (100.0) <kernel> : genunix`clock
Apparantly, clock should be the top cause for wakeups, not cv_wakeup
if your system is in idle.

I have cpupm and cpu-threshold setup...it used to work on my Travelmate
5720, not any more after svn111..
You can check the system by "mpstat" or "vmstat" or "prstat" to see the cpu
utilization and what is using CPU.
