Yah, that's completely weird why it would be passing a negative number to write().  Almost like it got a bad value from stat() or something?

On the RPI:

    sudo tcpdump -w nfs-fail.pcap port 2049

...ought to do it.  Run that command on the RPI, attempt the test case on the Sun, ^C the tcpdump on the RPI, and the .pcap file should have a packet capture that can be easily sliced and diced in Wireshark.
