Sounds like you have a "rev 1" chip on the board and the ethernet you're
attaching it to has noise problems which are triggering a bug in the chip
that causes the receiver to lock up. The problem is especially acute when
the interface is in 10Mbps mode. The best solution: find out why your network
has garbage on it and fix it. Some hubs will filter out the garbage, so using
a different hub might also fix the problem. Another solution: replace the
card with a newer one that has the fixed NIC ("rev 2").
