Including the XFS mailing list in here too because it may be an XFS bug looking at the call trace.

System: Debian Testing
Kernel: 2.6.20
Config: Attached

I was running apt-get dist-upgrade as I always do to get the latest packages upgraded and the kernel OOPS'd when it was upgrading 'tzdata' and the process went into D-state and I had to reboot.

The config file is from 2.6.20 but it had been moved to a 2.6.22 directory for an upgrade, but all of the options have been left unchanged.

Here is the *OOPS I captured via dmesg before I rebooted:

Not sure if this helps but when this happened, any file that was open()
for read/write seem to have also been corrupted..

Seems like it was NULL'd out?
