OK, so it appears the kernel is working.  Now focus is on the root
file system and the NFS server setup.

We use these images over NFS all the time - and for the kernel it does
not make much of a difference what the underlying file system type is;
NFS or ext* or xfs or whatever (assuming some minimal requirements are

I don't know much about your setup, so I can only speculate... Either
something went wrong when installing the root file system, or there
are problems with your nFS server configuration.

- Did you try a fresh installation of the root file system?

- Try running a network sniffer when booting, and check which NFS
  accesses are done, and where the booting stops.
