I think this is your real problem, that you're rescanning the entire
bus.  I don't think that's the route we'd recommend taking.

Why don't you call pci_scan_slot() instead?  You won't get the benefit of
pcibios_fixup_bus(), but I'm not convinced that's safe to call on a bus
that's already been scanned.
