The board has a Intel/DEC 21152 PCI bridge, and two Intel S82558B ethernet controllers - all of which are found and initialized. The board shows up as fxp0 and fxp1 under pcib1. Both ports indicate a link to the switch, and show activity. The problem is that performance for both ports is, shall we say, extremely lacking. I will see normal performance for a few seconds, then the board will "disappear" for several seconds, then "reappear". In some cases, the board will quit responding so long that services will time out. When I ssh into the router through one of the ports on this board, I can see the remote end stop responding to my typing in mid-stream. Other than the fact that remote hosts are having a devil of a time talking to the router when this board is used, there is nothing in the logs to indicate trouble, and the machine is stable. The original NIC works fine - and I use it to log in and halt the box when I am testing. Is this just a bad board, or is something else going on? If anything, I would suspect the bridge chip, as both ports exhibit this behavior. Thanks! - Seth Henry
