Public bug reported:
Description: Ubuntu 12.04 LTS
Release: 12.04
Dell Inspirion 910
Close lid to suspend. Most of the time resumes correctly - log in
screen, etc. Occasionally, I only get a blank screen with a cursor.
Only resolution is a hard reboot.
Providing part of the pm-suspend log with errors that I see.
