[c-nsp] Boot strangeness on 2821

[nealr]

  What image are you using? If you've swapped flash and the image stays 
with the box you're down to memory or mainboard issues, right? Swap dram 
next from the good to bad machine? If it has two memory sticks pull one 
and see if it follows a particular card or slot.    Teh Google is very 
quiet about this one - a few people report dead hardware doing this and 
that is all.


   Sounds like they're new ... get the reseller to look at them?
