Hang on S3 exit (Cezanne)
Brief summary of the problem:
Laptop suspends and resumes correctly most times, however occasionally resume from S3 fails, the screen stays blank, the system is unresponsive and a hard reset is needed.
Note that on this machine s2idle doesn't work at all, and the amd-pmc module does not load.
