So I have an e1000 device (single port) on one PCI bus and another 4 port 82580 chip on another PCI bus.  The startup 
enumeration finds 3 of the 4 ports.  The last port fails with the following error:
Mar 26 15:42:09    2    17     0 addup_resources: Alloc mem failed
Mar 26 15:42:09    2    10     0 pci_attach_device failed

Anyone have ideas why this would happen? It does not appear to have any reason to occur. Put the same card in a PC and 
the hardware *is* working.

Thanks.
