Hi,

have you tried with HT turned off? (just a guess)

And by the way, I am interested in how far CX states higher than C1 are 
already supported, I know that there are Problems with the old USB Stack 
and it's polling. Is that solved already? My -STABLE PentiumM Notebook 
really behaves bad when I enable CX states above C1, but I assume that 
has changed with this -CURRENT.

best regards
