Got lucky, sort of.  I was just working in a virtual terminal
when the lockup occurred.  That doesn't rule out X in that
X was running (I had just opened the terminal and was reading
a man page), however, it suggests the problem might not be
with X.  That is consistent with the observation that restarting
gdm3 does not clear the fault.

Found the following lines (more of same) in kern.log at the time
of the lockup.  However, I don't see them for other lockups
(a lockup occurred while I was typing this email), so it could
be a red-herring:
