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): 2.6.11-1.14_FC3 How reproducible: Very often Steps to Reproduce: 1. Log out of GNOME. Might be to do with any number of things. :-/ Actual results: Kernel panic - not syncing: drivers/block/cfq-iosched.c:1065: spin_is_locked on uninitialized spinlock ffff8100cc184838. (Tainted: G M ) Additional info: 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 described in bug #155472 ...
