Comment 3 Eduardo Habkost 2007-10-11 13:03:08 UTC 
The Oops looks like bug #234008. Could you confirm if the problem is gone with 
a newer kernel (the latest kernel on either FC-6, F-7 or Rawhide).
Comment 4 Bruno Wolff III 2007-10-13 17:59:49 UTC 
I tried 2.6.20-2936.fc7xen and didn't see the problem. The string 'BUG' did not
appear in the syslog entries from the boot and for the short (a couple of
minutes) I was running with this kernel nothing odd happened. I tried it on the
same machine as I had previously had the problem on.
