Bad things happening to journaled filesystem machines; Was: Oops in kjournald

["Jeffrey E. Hundstad" <jeffrey.hundstad@mnsu.edu>]

I've had 4 machines do the similiar things.  It happens during backups 
or during updatedb.  This has happened on 2.6.9, 2.6.10, 2.6.10-ac7, and 
2.6.10-ac8.  I've seen several similiar reports with journaled file 
systems.  I use XFS exclusively; but have seen reports on XFS and EXT3.  
I would report something more useful but what I'm usually left with is 
XFS unmounted and nothing useful on the screen.  This has been on Xeon, 
Pentium-3 and Athlon systems. ...wish I could report more but perhaps it 
will add /part/ of a data point.
