hi guys
I have a couple of miniPCI Oxford Semiconductor Ltd OX16PCI954 cards
installed, and the dmesg looks weird

espeially these lines
pci_bus 0000:00: root bus resource [mem 0x50000000-0x5fffffff]
pci_bus 0000:00: root bus resource [io  0x18800000-0x188fffff]
pci_bus 0000:00: root bus resource [??? 0x00000000 flags 0x0]
pci_bus 0000:00: No busn resource found for root bus, will use [bus 00-ff]
pci 0000:00:00.0: [Firmware Bug]: reg 0x14: invalid BAR (can't size)
pci 0000:00:00.0: [Firmware Bug]: reg 0x18: invalid BAR (can't size)

besides, I am experimenting crashes happening in burn-in tests, and I
do suspect it's something related to the newly added cards

any enlightenment?
