The best advice I can give is to put a hub between the PC and the DE2 and use a sniffer for DE2 packets while going through the NIOS debugger. If the system is going down after an ARP, best guess is you are sending an ARP packet which something on the network is unhappy about.

If the hub doesn't get you any farther, check the OS requirements for the DE2.

Using a switch, and not sending ARP, with just a PC and DE2 connected should tell you if that is the problem. Routers usually require a bit of work to shut off enough functionality to turn it into a switch.

If the DE2 dies after the first packet sent, there is likely an issue with the DM9000 registers. Sending broadcasts will tell if that's the issue.

One thing that is strange, if you only have the one DE2, then you only have to worry about a MAC address. Tell me how things go with the DE2 and a PC connected via switch.
