System freeze after VFS:Mount root (ext2 filesystem)

[Paul English]

Okay - I went through this document:
http://www.stanford.edu/~alfw/PXE-Kickstart/
to do a PXE kickstart. Not bad in that right off the bat it managed to 
boot off the network.

But...

It successfully boots off the network, then says:

VFS:Mount root (ext2 filesystem)
and stops. The machine isn't hung, that's just as far as it gets.

On the console (alt-F3) it tells me:

Alt-f3 gives me:

doing kickstart... setting it up
reverse name lookup failed (I checked this one out, it seems to be NBD)
url is 10.0.1.1:/data/Kickstart/ks-WB30.cfg
file location: nfs://10.0.1.1:/data/Kickstart/ks-WB30.cfg

And that is it! Nothing more about failing to mount the nfs directory or 
anything. It gets the kickstart file and then just stops. Hitting enter no 
longer makes the cursor move down the screen, but the "alt-F<x>" commands 
work and control-alt-delete works. 

At this point it looks like it is saying "I know where ks.cfg is, and I'm 
about to get it" but never does get it. 

Any help appreciated,
Paul
