Hi Bjorn: Thanks for your comments firstly. The platform only has one PCIe RC mode host, connected one INTEL 4965AGN wifi card. Doesn't have PCIe bridge device. The following log is generated on one X86 machine. It seems that the 00:00:0 is assigned to the PCI bridge device, is it? "00:00.0 Host bridge: Intel Corporation 5520 I/O Hub to ESI Port (rev 13)" About the device address, do you means that the RC mode PCIe host should be scanned, and assigned the address too?

The device address (bus 0, > device 0, function 0) is unusual, so I'd double-check that.
