full dmesg captured after oops
Comment 2 Juergen Weigert 2008-10-08 01:01:05 UTC 
For what it is worth:
- The machine suspends and resumes daily. This happend after resume after working for several hours.
- The machine is connected to an external monitor, using a large enough virtual screen for both internal and external monitor.
- almost every second resume hangs and needs to be resolved by power-button.
