No - Loved you post - Very insiteful.  Although now I am wondering if it
was neccessary (see below) - But I still thank you.  I personally love
the opertunity to learn something new.

I guess I have used the wrong term and/or have the wrong understanding. 
When I did consecutive 'ifconfig' while NFS was 'frozen' I could watch
the RX errors going up and up and up on 'linuxbox' but stayed at zero on
'kingpin'.  Even now, after things in the fstab file have been changes,
'linuxbox' shows 3 errors and kingpin shows none.

So is this still a hardware problem, or something else? 

I have switched out wires, a number of different time and different
combo's - so unless ALL the patch cables in my house are bad, the cables
are fine.  I also swithced ports (origianlly on 2 and 3, switched them
to 1 and 4).  None of this lead to any change.  I could trade out the
router, but it would be with a 10MB router, the one I have now is 100MB.

I played with the setting in fstab by starting at the rsize=8192, and
then reducing by 1/2 each time.  I  would run xmms to play an mp3 file
located on the server.  I then would keep an eye on 'netstat -i' in a
terminal window.

   When rsize=8192, netstat showed RX-ERR increasing by 5 for every
        increase of 7 in RX-OK   
   When rsize=4096, netstat showed RX-ERR increasing by 1 for every
        increase of 2 in RX-OK
   When rsize=2048, netstat showed RX-ERR remaining at 0, and RX-OK
        increasing.

As a note, the above is not very scientific, just a matter of
continously running 'netstat -i' and doing some quick
math.
