I am having problems getting an SR-IOV device to run on the latest Xen pv-ops
Dom0 kernel with Xen 4.0.0-testing tree. Note that this actually all works when
I run that same pv-ops Dom0 kernel *without* the Xen hypervisor, so the problem
must be Xen specific. The Dom0 kernel is from the latest pv-ops git tree.
Xen/Dom0 boot fine, then I load the driver on the SR-IOV device, and I get the
following kernel crash:

I boot Xen with 'dom0_mem=max:1024M iommu=0' set in GRUB. The system supports
VT-d, but I am disabling it.
I am not quite sure where to further look for the problem. Is the a bug in the
driver (but then it works when booting Dom0 without Xen)? Or did I
mis-configure something? I am not running any guests yet, and I don't use
pciback to hide devices either. This is just trying to boot up Dom0.
Any help would be greatly appreciated. Below is also my kernel configuration,
if that is of any help.
Thanks,
Anna
