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
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.
Okay, confirmed fixed with kernel-xen-2.6.25-0.20.rc8.fc9 (Not yet tagged for F9, but will be soon)
