Subject: 2.6.20 (XFS? related) crash after uptime of > 180 days during apt-get
 dist-upgrade on Debian Testing

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:

I doubt I can reproduce it as it has happened after 180 days or so, and I 
am upgrading to 2.6.22.6 but I was wondering what exactly happened here?

Thanks!

Justin.
