I had a similar problem with a 2.4.25 Kernel. I get the following errors: PCI: Cannot allocate resource region 0 of device 00:1b.0 PCI: moved device 00:1b.0 resource 0 (200) to e0000000 I solved the problem by adding hose->last_busno = pciauto_bus_scan(hose, hose->first_busno); at the end of the function mpc5xxx_find_bridges() in arch/ppc/kernel/mpc5xxx_pci.c I didnt looked in the 2.6.11.7 Kernel, but maybe this helps you! Best regards Heiko
