Hello,
I'm running a vanilla 2.6.7 on a workstation. It appears to have Oops'ed
yesterday morning while the slocate/updatedb cronjob was running:

The box seems to be stable since then (i've not rebooted it yet), although
the updatedb cronjob is hung. I'm not 100% certain that this is a XFS
issue, but since i see a ton of xfs references in the oops, i'm asking
here first. thanks.
