It's possible - this is the only information I have on this crash for
the moment.  It's definitely indicitiave of the problem occuring, as
nfs shares from the VMs running on here stop responding immediately
after the watchdog fires.

What can I do to further track down the cause of this issue?

X isn't running on here - this is a system that's meant to run
headless, and as such, there's only a text login prompt at any
given time on the console.

The data loss I referenced is the system becoming unresponsive, and
failing to write cached data to disk.
