Same thing here - we have a Xen host (64 bits) running a couple of
Windows 2003 VMs.
Without the GPL PV drivers, heavy I/O caused almost-reproducible crashes
(for instance, downloading a large file thru CIFS hung the Windows VM).
With the GPL PV drivers, I/O is of course *a lot* faster and no crash
has been seen yet.
