Hi,
I too had a similar problem with our custom 440GX board - this week in
fact. It would DHCP, mount NFS then keep on reporting that the server
was not responding. I eventually tracked it down to the fact that we
are running a single MII phy and the phy map was not being setup
correctly by my port. As soon as I changed this in the arch_setup it
has worked ever since. BTW it is linuxppc 2.6.8.1,RevC
440,100BaseTX,busybox root. This may not be Hiroshis problem but
thought I would add to the conversation...
