I bought two of the cards in order to decide whether or not I wanted
to use them in my research group's PII cluster.  Right now, they're
plugged into a 233MHz Pentium Pro and a 400Mhz K6-2 (using an
Aladdin V-based board).  I did a bunch of NFS testing over the
gigabit link last week and didn't see any glitches.

The only "problems" that I've seen are (1) the round-trip latency
for small UDP packets is at least 50% higher than FastEthernet
on the same hardware and (2) the round-trip latency is highly
variable.
