Hi Kim,

OK, probably operator error.  I claim to be using 1.3.2-rc2 but my 
repository clone could be introducing problems.  I'll do a clean clone 
and rebuild of u-boot, hopefully that is all it is.

It is connection is through a commercial switch, should be 100bT full 
duplex (not verified, cannot see the blinky lights from here).  I don't 
know the board rev off-hand (I'm not on-site at the moment).

=> version
U-Boot 1.3.2-rc2-g330a77f6-dirty (Feb 25 2008 - 22:21:12) MPC83XX
