Boot with NFS on MIPS32

Hi All,

I have one MIPS32 embedded system with Linux Kernel 2.6.23.17. Right
now, I have problem to boot from NFS. The NFS server works fine. I am
able to mount the directory from anther Linux work station. I attach
the .config file, there maybe some config flags I forget to open.

Thanks for your help,

Mike


Here is the kernel command line:
===========================
Kernel command line: root=/dev/nfs rw
nfsroot=47.1.1.108:/localdisk/rootfs/
ip=47.1.1.2:47.1.1.1:255.255.255.0:Min-MIPS:eth0:off

Here is the error:
