Hmm...
IIRC TEMAC is configured in FIFO mode.
And I thought the problem could be due to small FIFOs. So that the default
NFS reply of 4kbytes could not fit into the receive FIFO, and the CPU is not
fast enough to read the reply out of the FIFO before it overflows.
But your observations don't seem to confirm this is the case.

Anyway, you could try adding
   nfsroot=,rsize=1024,wsize=1024
to your cmdline just in case...

Thanks,
Andrei
