Hmm. I had a similar issue a while ago and the reason was that on PXA3xx
CPUs, the timer register behaved differently than on PXA2xxs and that
was never tested. In fact, it was counting magnitudes faster there which
made the network code bail out way to early. This was fixed for the
platform I'm working with, but maybe you got a similar problem.

Other than that, there might be something weird with your network. I'd
suggest running wireshark on some host on that LAN and have a close look
on the packets.
