I believe I have successfully solved the bug now by reading all the comments again and found a solution in #96. I added
echo 0 >/proc/sys/kernel/nmi_watchdog
before "exit 0" in the file etc/rc.local. I have used the system a few hours/days/re-starts/hibernates since and no bug has occured by now. My working configuration is:
- Ubuntu Studio 12.04 fresh install
- Dell Studio 1558 with ATI Radeon HD 4500.
- Gnome Shell
- Solution from comment #96
