Hi there!
I got this oops today after an uptime of many days.
On the machine runs a squid and the fs's are ext3.
It also exports some directories over nfs and has some
iptables rules.

After this oops squid hung in the kernel and was unkillable.
Also a reboot did not work. Had to manually reset the server.
