Public bug reported:
I've got a Lenovo ThinkPad T430s with a MiniDock Series 3. In Ubuntu
13.04, the ethernet connection is not available after undocking. The
output of 'ip link show dev eth0' shows <NO_CARRIER> status if a CAT5
cable is plugged into the ethernet port after undocking. The link light
comes on, but it's impossible to use the connection. It seems as if the
system still thinks it's in the docked state, so the onboard ethernet
port is overridden by the now-disconnected docking station ethernet
port.
This kernel will exhibit the problem: 3.8.0-18-generic
This kernel from the mainline PPA will not exhibit the problem:
3.9.0-030900rc6
Also, the output of 'acpi_listen' is interesting when comparing the working and
broken kernels.
3.9.0-030900rc6 (working):
