So when I came back to the computer I had the usual lockup, but this time a stacktrace as well!

Someone with perms can set this for fc6, and clear NEEDINFO unless there's more to collect. --- Additional comment from alan@redhat.com on 2007-01-02 10:42:49 EST --- Upstream patch prepared --- Additional comment from bill-bugzilla.redhat.com@bfccomputing.com on 2007-01-04 15:33:24 EST --- URL for Alan's patch: http://lkml.org/lkml/diff/2007/1/2/126/1 (I'm not "sufficiently empowered") to modify the URL field.

in kernel-2.6.18-231.el5 You can download this test kernel (or newer) from http://people.redhat.com/jwilson/el5 Detailed testing feedback is always welcomed.
Prarit, Do you know what hardware I need to reproduce this bug? Thank you.
(In reply to comment #18) > Prarit, > > Do you know what hardware I need to reproduce this bug? > > Thank you. No HW available unfortunately. But you can sanity test with any system with a DVD drive in it. P.
