I'm not using an epic with the SMP branch, but I've never seen anything
like this.  The epic driver hasn't changed since November 12, so I don't
think there is any updating to be done.

Are you sure you don't have a link problem?  If you have a duplex mismatch
you may be getting a ton of errors during bulk data transfers and the error
recovery code could be resetting the interface.  Look at the output of the
'netstat -in' command:

Name  Mtu   Network       Address              Ipkts Ierrs    Opkts Oerrs Colls
epic0 1500  <Link>        00:e0:29:45:8d:ac   540172     0   579143     0     0
epic0 1500  192.168.44    192.168.44.1        540172     0   579143     0     0
epic0 1500  fe80::/64     fe80::2e0:29ff:fe   540172     0   579143     0     0

If have anything in the Ierrs or Oerrs column there is a potential link
problem.
