I've had this behavior also with Intel Pro 1000 cards using the em
driver. I picked up a lot of 4 of them off ebay and never figured out
if it was a driver problem or faulty hardware. I went back to FreeNAS
on that same box (7.2-RELEASE-p4) and it seems ok except my Netgear
gigabit switch also died so I'm currently plugged into a 100Mbps
switch.
