Bug Description
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.
