[Nottingham] Deciphering a kernel Ooops

Hi Folks,

Just had this system slowly die just now. Checking the logs, the only 
anomalies are a few fd0 errors for a dodgy floppy disk from yesterday, 
and a kernel Ooops from earlier this morning.

So who can give a more human translation of the Ooops message?

The PID 29632 is something that was a newly created task at about that time.

/var/log/messages snippet attached.

Mandrake 10.0.1, AMD 1800XP Palomino, 2x HDDs, nVidia AGP graphics card, 
MSI K7T266 Pro2RU motherboard.

Thanks,
Martin
