Issue
Under 12.04 screen freezes intermittently not evidently related to a specific 
application or user action.

Symptom
- screen freezes
- keyboard stops responding (caps lock, num lock lights stop working)
- mouse pointer continues to work

Frequently PC locks after entering suspend and will not resume at all,
this may be unrelated.
