I'm working with a TYAN Tomcat board (i815, Ghz CPU). It's in a 1U machine with a butterfly riser so that I get two riser connections to one PCI slot. When I put Intel EEPRO nics in each slot, I can pass 30Mbps of traffic on each NIC without dropping a single packet (In two days of running).
If I run 20Mbps on one of the DLINK ports, I'm fine, but if I run 10Mbps on two of the DLINK ports, I start seeing dropped packets on every interface, and port errors like RX-FIFO.
So, I'm thinking that the DLINK NIC must be screwing up the PCI bus somehow when more than one of it's interfaces is passing any significant traffic. I have been able to run 10Mbps on all 8 ports of two DLINKs on an Intel EEA2 (i815) board, so I suspect the MB.
Does anyone have any ideas how to go about trouble-shooting this farther?
Thanks, Ben
