The issue is known and worked on, unfortunately no more information yet.
We're tracking the issue and stuff (debug patches, etc) over here (at
e1000.sf.net):
http://sourceforge.net/tracker/index.php?func=detail&aid=1463045&group_id=42302&atid=447449
For now, try to see if turning off tso using ethtool helps.
Cheers,
Auke
