em0 failed to work at 1000baseTX. WAS [Re: em0 - bge0 failed to work at 1000baseTX]

Stefan,

         I am having a long weekend and am supposed to be doing
something other than this :) However, when I get back in the office
on Tuesday I will see if I can repro this, so just to make sure, tell
me what the PCI ID of the two cards are when it fails with Intel
on both sides, that should be easy.

Jack
