Comment 6 for bug 605133

Update: removing the ATI display driver and my machine suspends and resumes happily. This implies its a bug in the ATI closed source display driver -not something that anyone else can fix.

I tried the debugging kernel suspend/resume tricks, but no crash report gets generated. Is there any way to force some stack trace during a suspend or otherwise debug a display driver that is hanging on suspend? Alternatively, how could we improve the OS so that if a driver doesn't suspend properly, that failure is detected and acted on, rather than leaving the laptop to stay live and overheating as it is transported?

I can possibly see how to do failure detection , but acting on the failure, that's tricky.
