Hi!
bus master activity: is changing all the time, mostly 555555555 and
aaaaaaa, and cpu refuses to enter C3 for obvious reasons. I compiled
out USB and sound... Does anybody else see the same problem?

I did notice too that it was never in C3 apart from a bit right at the
beginning, since 2.6.10. It has always been like that up to 2.6.6, became
better from 2.6.7 (but had other problems with that).

P.S. I didn't check bus master activity. How do you do that?

Good, so I'm not alone.

There's something wrong with bus master activity indicator: it seems
to be updated every HZ or something like that... that results in a bad
stuff if HZ=100... activiy is now non-zero and machine refuses to go
C3.

can you try to kill all bm_activity++ things in
drivers/acpi/processor.c and see what it does to your power
consumption. (Warning: it may do bad stuff to your performance).
