This sounds like the driver is trying (and failing) to map a list of
grant references. Usually when this happens, you will see some output
on the Xen console (which you can read by typing "xm dmesg" in Dom0,
or attaching a serial line). This may help the developers - or people
on this list - to diagnose the problem.

Hope this helps.
