Looks like you're not getting actual link - is the link up?
sudo mii-tool eth0
should see:
eth0: negotiated 1000baseT-FD flow-control, link ok
Should also see blinky lights on the nic.
Do you use a dock with it? They sometimes switch between dock and
build-in causing one or the other not to work or link, even sometimes
getting stuck, but that's usually a driver/os thing.
