unable to boot from NFS

I recently reinstalled BSP package and now during bootup it fails during the NFS portion.
Here's a snippet of the output. Does anybody have a suggestion?

Based on the error message:
    Root-NFS: Server returned error -13 while mounting /tftpboot/ltib/rootfs

I'd make sure your server is exporting /tftpboot/ltib/rootfs.

Does your /etc/exports file have a line similar to:
    /tftpboot/ltib/rootfs     *(rw,no_root_squash,no_subtree_check,async)

After doing that did you restart the NFS server to reread the exports? I do the following:
    sudo /etc/init.d/nfsserver restart

Does any of that help?
