Hi All,

I am currently attempting to get the 2.6 Linux Kernel
( Sylvain's Kernel from
http://gitbits.246tNt.com/gitbits/linux-2.6-mpc52xx.git)  booting over
NFS on a Freescale LITE5200 board.  At present, I have been able to
successfully mount the rootfs over NFS, but am encountering the
following issue... 

After the kernel frees the unused memory after the NFS mount, I get a
string of 

request_module: runaway loop modprobe binfmt-4c46

errors and the console appears to hang.  Any help would be greatly
appreciated!
Are you sure you are trying to boot a ppc NFS root ? :) Looks to me like
you are trying to boot an x86 one...

Ben.
