I didn't try with a rhel5.5 guest but I noticed that the device we are
trying to passthrough is a multifunction device:

02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5716 Gigabit 
Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5716 Gigabit 
Ethernet (rev 20)

when the VM is shutdown Xen receives an NMI trying to mask an msix from
__pirq_guest_unbind.
The NMI happens even if we leave the other function unused or if we
assign it to the same VM.
