I think this explains why the BAR isn't reset: Unlike pci_device_reset(), 
device_cold_reset() lacks calling pci_do_device_reset() which would take care 
of the BARs.

Paolo, Peter: Should we switch to pci_device_reset() in pci_xen_ide_unplug()? 
Or is device_cold_reset() supposed to do everything?

Best regards,
