If this is all alone on a bus of its own, we can certainly handle that.
Maybe we can make it a module parameter or something.
If my devices where the only one on the bus I would not have stumbled on
this bug. I would have removed them all before reloading and would have
scanned and empty PCI bus list after the reloading.
Alas, the CPU itself is a pci device. Upon scanning the bus it is it who
is duplicated. Upon trying to "pci_bus_add_devices()" you get resource
collision.
Do you perceive any down side to my suggested patch?
It seems (to me) really logical that a device can not and should not be
added twice to a pci bus device list.
