(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
