Kernel Oops in apparmor

[Stefan Bader]

Lucid Server 10.04.1 lost all network both in and outbound. When I got to the console I saw in dmesg that it had oops'ed. Tried bring interfaces up/down with no success. Did a soft reboot on the box and it oops'ed on the way down and wedged. dmesg showed the same oops from approx 7am to 13:00ish when I rebooted.

Note Steffan created this bug for me due to LP having timeout issues.
