I have a similar problem except that the switch in my case is a Intel
Express 460T.

I've found that the traffic stops, when I turn "flow control" off, on
the port of the switch the eepro100 is connected to.

One would expect that an Intel NIC and an Intel switch would be able to
understand each other?

I'd very much like a better solution than turning flow control off.

The only difference is that my cards reports "Board assembly 721383-016"
(and that I use IRQ 9, but I guess that shouldn't matter).

Does this help anyone?

PS: I use a 2.4.4-kernel.
