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"). -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
