Public bug reported:
The wired ethernet connection works properly in the common way. But
with the use of a port replicator this becomes weird.
When I dock-in while the computer is running, I get no ethernet link.
/var/log/syslog shows for this:
Oct 30 13:06:44 srenW540 NetworkManager[18816]: <info> Activation (eth0)

The ONLY possible way to get an ethernet link with the port replicator
is this:
1. Shut down notebook and dock-out
2. Plug off the port replicator's AC (!)
3. Wait a few seconds
4. Dock-in and plugin-in the replicator's AC
5. Boot
Now, the ethernet link will be established. BUT: If you dock-out and dock-in
now, the link gets not established as well.
This is extremely uncomfortable and the use of a port replicator is a mess with
this.
Interface DownUp when the link can not be established does not work as well.
Please help!
