Could you put in some debugging print statements in pci_scan_bus?

right after this line:
printk(BIOS_DEBUG, "PCI: pci_scan_bus for bus %02x\n", bus->secondary);
    add:	
printk(BIOS_DEBUG, “pci_scan_bus min_devfn %x max_devfn %x \n”,
min_devfn, max_devfn);

The max_devfn should be < 0x18 so that the fam10 doesn’t get
enumerated again.  It looks like you're not getting out of the loop.

Thanks,
Myles

hi myles,
   you are right, the max_devfn is 0xff. I do not know what caused this.
Still debugging..
