@ Jan Willies :
Ok, its now great to know that its not just a problem limited to core duo
cpu's but also amd based machines. Btw, do we all have hp notebooks, cos it
might be something with the bios probably. Also, do all of us have a discrete
graphics card ?
Yes, you can go through all the details in th last thread - everything remains
normal, except that the machine runs hotter and fans whine frequently and
obviously battery drained quickly, but no effect on performance. And
hibernation (suspend2) and back brings it back to normal state again.
About the C1 not being used, someone (Venkatesh Pallipadi, Intel) clarified
that by C0, it means both C0 and C1. The exact state can't be determined. Only
C0-C1 / C2 / C3 times can be measured and distinguished apparently. And besides
100% in C0 will kill the cpu (try giving idle=poll in kernel command line).
But about C3 not being used - thats probably really not being used. However,
as said in many threads earlier, the hardware might really be invoking deeper C
states when it shows in powertop as just C2.
Btw, Is your cpu dual core? If so, does disabling smp work ? Do you also get
the "tsc marked unstable" message in kernel log ?

I have the same weird problem with my AMD-based Medion MD96400 Laptop.
Some time after booting it goes up to ~80000 wakeup/s and stays there. I
can shut down X and remove all modules, no change at all. When I
reactivate the notebook from S3, the wakeups are gone.
I never have pcmcia/yenta_socket loaded so I guess that's not working
for me.
Cn Avg residency P-states (frequencies)
C0 (cpu running) (100.0%) 1.60 Ghz 0.0%
C1 0.0ms ( 0.0%) 800 Mhz 100.0%
C2 0.0ms ( 0.0%)
C3 0.0ms ( 0.0%)
Wakeups-from-idle per second : 79237.8 interval: 10.0s
Top causes for wakeups:

23.3% ( 51.1) mpd : schedule_timeout (process_timeout)

0.5% ( 1.0) wpa_supplicant : rt2x00lib_config
(delayed_work_timer_fn)
Another thing I discovered is, that my Laptop switches only between C0
and C2. C1/C3 are never used at all. HPET doesn't seem to work.
