   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...
