    Can you please post the full boot log?  Also, from the snippet you've pasted not all of the parameters you've set are being obeyed (root path is empty).  Finally, is the target NFS root one setup by the SDK scripts?  If not, were you careful to make sure it was extracted with root permissions (either as root or sudo tar ...) ?  Thanks.
