Error with Intel 82571EB on xeon (em64t) latest 3.9 snapshot

Darrian Hale
Hello, I have a machine with 2x82571EB network controllers with 4  
ports each.  The first of the 4 ports on each controller will not  
load with the error "Allocation of PCI resources failed".

This error only occurs on the amd64 build, not the i386 build.

The machine i have is a Nexcom Network Appliance 2107.  I can provide  
a testing machine if necessary.

dmesg is below
