Is your em0 built into the motherboard or a plug in board.
How old is your motherboard.

My em0 and em1 were built in on the motherboard. Had no problems release 
9 through 11. For 12.0 started having network problems. Disabled them in 
bios and replaced with PCIE type plug in cards. Every thing back to normal.

Just my 2 cents.
