Hello all
   I have an Intel gigabit card that i plugged int that doesn't seem
to attach at all.
It is a PCI-X card plugged into a PCI slot.

I am willing to dig a bit into the code too if someone can point to a
little more detail.

The relevant piece of dmesg is

wm0 at pci1 dev 10 function 0: Intel i82542 1000BASE-X Ethernet, rev. 3
wm0: unable to wake from power state D3

I can put the actual dmesg also if it helps.
