AFAIK, it's a bug in some revisions of the EtherExpress card.  The fix is 
to down and up the interface using ifconfig -- that'll bring it back to 
life.  Ugly, but it works.

When we were using one of those cards, I wrote a quick perl script that 
ran every minute to see if the world was alive and reset the interface.  
It's at the end of this message.  It worked for me, but YMMV.
