I am running the simple socket server example on my custom board. I'm having a problem with it freezing right after "auto-negotiation passed".

"No free buffers for rx" usually means that the IP stacks is receiving too many packets and can't handle the traffic. Is there a lot going on on the network? Especially broadcast packets, that would go through the MAC address filter in the TSE component.

There could be a hardware problem that would cause the receive DMA to get data even when there are no packets on the network. Could you use a signaltap probe on the Avalon Stream interface between the Ethernet MAC and the receive DMA? Check if there is any traffic there.
