Thanks Dave.

I can work on that tonight.

Oddly, since the problem is kernel related (308 doesn't do it, 348 does),
the system shuts down the same way no matter what kernel I'm using.  So
what would be the difference?  The umounts and running processes shouldn't
change.  Just seems to me that some resource isn't being released.  And
only with kernel 348 and XFS.  Quite puzzling..........

Any suggestions on how I would debug this?
