Bug#696554: System freezes and lockups
Okay, less than 24hrs uptime and the system froze completely. I was really hoping (with dumb luck) the newly landed 3.2.35 kernel would help out even though there were no specific nouveaux changes.

No, this time I was unable to switch to another console
> * does the mouse pointer still move? (I guess not?)
Yes, the mouse pointer was still moving
> * can you find anything specific that triggers it? (so far, no?)
Still no common trigger. This time I was using synaptic package manager. Fortunately no critical operation was underway, just refreshing the package database.
Looks like more of the same in the syslog:
