FYI, I just ran into this bug on another box, with an onboard em nic, so
I dont think its a one off hardware issue. AMD64, FreeBSD 10.0-STABLE
#4 r270560:
This is on an Intel MB S1200BTL ( S1200BT.86B.02.00.0035.030220120927)
Unfortunately, this is also a production box so its difficult to test.
I am going to see if I can find a similar MB to test against.
