Still sounds like some kind of hardware problem, because it runs fine
as long as it isn't under pressure and fails in a different way each
time. If it's always the same CPU, that may be a hint. Bad RAM is
the most frequent culprit for such unpredictable problems, though.
If you have the opportunity to disable SMP and try again (e.g., you
have a GENERIC kernel around that matches your userland), that would
be worth a shot.
