This is probably due to some kind of race in device backend
setup/teardown. My testing system creates and destroys domUs at a
very high rate compared to most normal environments.
At the moment this system is still running following this oops but I
want to reboot it as it has wedged in a way probably related to the
oops.

Yes, that would seem to be the case. /proc/version says
Linux version 2.6.18-6-xen-686 (Debian 2.6.18.dfsg.1-18etch6) (dannf@debian.org) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP Sat Jun 7 02:07:48 UTC 2008
So I shall reboot and I think we can assume this bug is fixed unless
it recurs.
Ian.
