Your intel 82559 card is not detected? So you have more than 2 interfaces in this box, and the intel 82559 is not shown?

We use latest intel drivers now, it was supposed to work if this card has linux driver.

I had some card recently that was not detected by ROS... and voila - after I replaced motherboard, all is working fine. on the old motherboard Ubuntu saw the NIC, ROS - didn't.
