Public bug reported:
This happens seemingly randomly. The error is:
[ 1308.068864] bad: scheduling from the idle thread!

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.
