Weird problem.  If you want to troubleshoot, you might get
it into failure mode, then run ethtool on the ethernet device
to see if auto-negotiation is happening properly, if the
Linux driver thinks link is detected, and so forth.

What chipset does your Ethernet use, and is it part
of the dock?  It appears that Intel driver modules
have a "debug" option that can be set, not sure if
that helps...
