My bad, the noise *wasn't* noise.  What worked for me was 1.3.1 (above 
results), which initializes the ethernet on start up.  When I cloned the 
u-boot repo (or u-boot-testing), the second ping hangs the board for me.

Is the fact that I don't have a valid env a clue (I have never bothered 
to save an env)?  Hmmmm, what env variables could be messing me up?  I 
would suspect the ethernet rotation one.  I don't have the second 
etherspiggot plugged in, but that should simply fail and rotate back to 
the first etherspiggot (scratches head).

Thanks,
