I just did a pull and a recompile.  

The kernel boots to the point where it wants to get the root.  I tell it the same root server I used before the rebuild, and the prompt comes back again asking for the root.

Any thoughts on where I should look?

usb/hub... root is from (tcp)[tcp]: 192.168.1.250
root is from (tcp)[192.168.1.250]:
