You may not be having a board problem or a kernel problem. I had exactly
the same problem with an almost identical configuration as you. Using
Etherreal at various points in my network, I found that an Ethernet switch
in the communication path was dropping packets before the board ever saw
them. I solved it the same way that you did (with rsize/wsize), and it has
worked fine ever since.
See my post on 7/26/2006, subject "Re: Slow boot with NFS, server not
responding".
