The problem is, the initial modification and subsequent changes to the powersave function were documented to fix an APSM hang, not cause it. I'm happy to submit a patch to undo that particular change but I'm not sure if it'll -break- things for other people. :) Someone with PCIe/APCI/APSM/general clue in the area of CPU + bus sleep states needs to step in and help. I'm just not equipped to fix the problem at the moment. Thanks, Adrian
