Bug Description
Running 3.8.0-19.30 or 3.8.0-20.31 (and likely some earlier versions), no carrier is detected by the OS on eth0 (e1000e driver) on my Latitude E6420. 'ip link' shows:
2: eth0: <NO-CARRIER,
link/ether 5c:26:0a:6c:7a:bd brd ff:ff:ff:ff:ff:ff
The physical lights on the port are green (left) and blinking amber (right).
If I dock the system and use the ethernet port on the dock, eth0 is fully functional.
This is not a hardware issue as the on-board port functions normally again if I boot into 3.5.0-27.46.
