Can't get port of RPC while boot linux(root NFS)

Hi, All

I've compliled a linux kernel with cfg_root_nfs, cfg_ip_dhcp, cfg_ip_rarp, cfg_ip_bootp. and set up tftp server and nfs server properly. the /home/client on server be exported as nfs root. some necessary files have been copied to there.

well, I boot the client machine by grub. the confgiure looks like:

ifconfig --address=xxx.xxx.xxx.xxx --server=yyy.yyy.yyy.yyy root (nd)
kernel /tftp-bootimg root=/dev/nfs nfsroot=yyy.yyy.yyy.yyy:/home/client

But it report error message said that can't get RPC port from protmap while mounting /home/client. Did I make something wrong?

BTW: the /home/client can be mount from client machine as non-root filesystem.
