[Bug 568549] [NEW] Dell T7500 Hangs/Freezes Repeatedly

[sog]

Public bug reported:

I have a Dell T7500 workstation running the AMD64 Lucid distribution,
fresh install, that completely hangs repeatedly, multiple times per day.
There is no obvious cause, which is making it difficult to pin down the
issue.

It does not appear to be related to USB devices or the sound card,
because the machine has frozen while those devices were unavailable due
to a separate bug.

The machine hangs completely, in that it is not just an X lockup. The
machine becomes unresponsive to ssh, and when systems are connected via
that protocol prior to a freeze they display no seriously abnormal
behavior, they just stop responding.

I'm attaching the recommended logs, and would be happy to provide any
other information that would assist in isolating the root cause of the
problem.
