I've just verified NetBSD domU with pci frontend. It behaves in the same 
way as linux domU with pci fronted and exported usb controller on pci. 
In other words, I see "Domain-Unnamed" in "--ps--" state after shutdown 
and I'm experiencing also network watchdog timeouts on bge0 network 
interface.

I have attached an output of domU dmesg and "pcictl pci0 list". I noted 
one suspicious line in domU dmesg:

  xen_alloc_contig: XENMEM_decrease_reservation failed!

which comes from _xen_alloc_contig() in xen_bus_dma.c file, line 102. 
Maybe this is related to the issue I have after shuting down of the domU...
