Bug Description

~uname -a
Linux ghost 2.6.20-16-generic #2 SMP Fri Aug 31 00:55:27 UTC 2007 i686 GNU/Linux

I am taking a system tar of the machine using the following command.
cd / && nice -n 19 tar -czf /mnt/sonofbeast/backup/ghost/.system-daily-20070918.tar.gz --exclude=cdrom --exclude=dev --exclude=home --exclude=media --exclude=mnt --exclude=proc --exclude=sys ./

The file being created is on a mounted nfs directory.

Several minutes or so into the backup I receive this kernel oops:

Usually followed by normal operation but a sustained high load average with very high idle time on the cpu. Other times I get a kernel panic and the machine completely freezes. This is what happend last time the machine froze.
