If you can't use different PCI slots for whatever reason, you should be
able to disable Function Level Reset in the xend scripts.

Here is a patch:
http://xen.markmail.org/search/?q=disable+flr#query:disable
flr+page:1+mid:7dbm675e4x4dawec+state:results

It may be able to be applied to the pci.py file on your system without
any recompiling etc., since it is just a python code change.

Hope that helps.

You should report bugs on xen bugzilla and to xen-devel if you can.
