I talked to Don about this once.  If this is the same problem, we
decided it occurred when talking to a slow network:  the transmit ring
fills up and stalls.  His driver currently does nothing in this
situation (I believe he was expecting such a stall to be the result of
hardware problems).

Lately, I've been using Eric Kasten's modifications to the hamachi
driver, at:

   http://www.nscl.msu.edu/~kasten/perf/hamachi/

I find this to be very robust ("it takes a licking and keeps on
ticking"), but I haven't tested for this problem (I was NFS root-booting
multiple nodes from a host on a 100BaseT connection to the GigE).  I
have another problem with netperf UDP tests.  Although this driver
doesn't solve those problems, the network still works after the UDP
fails.  I would recommend Eric's modifications.
