[Bug 605133] Re: Suspend/hibernate/resume failure in Ubuntu 10.04 64-bit on HP Pavilion dv4t-1000

[SteveLoughran]

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.
