Note that oddly, the second range of bus addresses looks -more-

than the first one...
Except that the first one is exactly the same bus address as my bare
metal system:
pci_bus 0000:00: root bus resource [io 0xffbeb000-0xffbfafff] (bus
address [0x100000000-0x10000ffff])
I only have one PCIe RAID card on the bare metal system. Not
surprising I never noticed the problem on it directly.
Can you show me the device-tree node for that PCI host bridge ?
It's a p4080ds, so it's in arch/powerpc/boot/
And that means that this bug affects a real hardware platform, so I think it makes it more valid to include it. The only reason it didn't affect me directly is because my only PCIe card doesn't have io, just mem BARs.
