Greg,

I'm getting the following message from the kernel on an embedded ppc32 
system:

PCI: Failed to allocate mem resource #9:100000@e0000000 for 0000:00:00.0

The HW setup is a PCIe host controller and an e1000 NIC card.  It appears 
that pci_bus_assign_resources() is trying to call pci_assign_resource() for 
the ROM and the resource for the ROM is [100000:1fffff] where the PHB is 
[c0000000:dfffffff].

It seems like the resno that pci_assign_resource is getting called with is 
wrong and thus pci_update_resource() doesn't get called.

any ideas?

Nope, sorry, any help debugging this is appreciated, pci resource
allocation is "tricky" :)

thanks,
