I would suggest you first start by loading ash.static or some other statically compiled shell (boot with "init=/bin/bash or init=/bin/ash.static, depending on what shell you have) and then go from there. If even that doesn't work, try cross compiling a static hello world and load that as the init (something like "init=/bin/hello"). What does you /etc/inittab look like? Pete
