Kernel panic: No init found.

Hi,

I try to run Hard Hat Linux from Montavista as described in the CDK 1.2
manual on an RPX lite board.
Unfortunately, the installation procedure is only for hosts with Red Hat
Linux, I hoped this would work for SuSE, too.

The problem has to do with the NFS filesystem. I can successfully download a
precompiled
Hard Hat Linux boot-image via TFTP and monitor this with the serial port.

The following is the output over the serial port...

----snip----

The filesystem seems to be mounted, but it does not find any files in there
although the full "linux tree" is available. I also tried adding
  init=/bin/init   init=bin/init    init=/opt/.../target/bin/init
to the boot arguments, but nothing helped.

Do you know that problem or have an idea? Any help is welcome. Thank in
advance.
