Description of problem:
Occasionally, when logging out of GNOME, the machine hangs and has to be reset.
I hooked up a parallel port console and got some debugging output: see below.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log out of GNOME. Might be to do with any number of things. :-/
Kernel panic - not syncing: drivers/block/cfq-iosched.c:1065: spin_is_locked on
uninitialized spinlock ffff8100cc184838. (Tainted: G M )
No idea what 'Tainted' is all about -- I haven't installed any third party drivers.
Do you use USB keys/drives? If so you might be suffering the same problems as
