I've bugzilla'd this before (#7860), but with no specific outcome. I'm now in a position where I have some fairly heavy-duty testing stuff at my disposal, including stuff like DriverStudio. Does anybody know how I can "trace" the successful suspend and resume in Windows XP, and then use this to work out what Linux is doing wrong? I don't even get to the first resume steps in Linux, so I'm guessing Windows XP does some voodoo to either ACPI or the EC before it suspends. Ideas welcome - thanks.
