Just saw this with 2.6.25-0.15.rc8.fc9.x86_64 while downloading packages during
a yum update:

Comment 1 Mark McLoughlin 2008-04-04 04:38:29 EDT
Seems to be quite reproducible - I've rebooted and restarted the update a few
times and after downloading a few megs, I got the same oops both times
Comment 2 Eduardo Habkost 2008-04-07 14:59:03 EDT
This should be solved on kernel-xen-2.6-2.6.25-0.17.rc8.fc9.

The Oops I was getting wasn't exactly the one in this bug's description, but I 
hope it had the same cause.
Comment 3 Mark McLoughlin 2008-04-10 09:23:21 EDT
Okay, confirmed fixed with kernel-xen-2.6.25-0.20.rc8.fc9

(Not yet tagged for F9, but will be soon)
