Hi,

I am trying to load a kernel with ramdisk support linked in it. It is a 2.4.5 
kernel, ported for Ocelot board running a PMC RM7000 chip.
The kernel hangs while trying to load the "init" process. The "init" is 
actually the sash program. I have placed the init in /sbin, /sbin and /etc.The 
"execve" in setup.c returns ENOEXEC while running /sbin/init. The 
CONFIG_BINFMT_ELF is set in the .config file.
The init has the x attribute.

Here's the output:

>g root=/dev/ram

Initial ramdisk at: 0x80285000 (1161262 bytes)

Any ideas?
