Bug Description

This happens seemingly randomly. The error is:
[ 1308.068864] bad: scheduling from the idle thread!
[ 1308.068873] Pid: 0, comm: swapper Not tainted 2.6.27-9-generic #1

It just repeats over and over until several of my log files expand to GigaBytes in size, by which time the computer is virtually useless and eventually freezes. Screenshots of the messages in gnome-terminal and one of my process list while this is happening are attached.
