I just mounted the ramdisk with a warning.
Is there any problem with unchecked fs? But I copied the image to host 'dd if=ramdisk.image of=/dev/ram' and I worked well. (It was given 2.2.13 kernel on linuxppc.org)
Anyway, actual problem appeared at calling at init process. I saw the source and it seems if there is no init then the kernel calls /bin/sh.
Of coarse, the shell is in the image, but the kernel couldn't find it.
---------------------------
Now booting the kernel
ttyS00 at 0x0380 is a SMC
ttyS01 at 0x0100 is a SCC
ttyS02 at 0x0200 is a SCC

RAM disk driver initialized: 16 RAM disks of 4096K size

RAMDISK: Compressed image found at block 0
EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

Warning: unable to open an initial console.
Kernel panic: No init found. Try passing init= option to kernel.

I have seen these errors before on an MVME2301. My problem was caused
by not having the proper devices in /dev. I had to add /dev/console and
/dev/ttyS0. Output from my (working) machine:
sh-2.03# ls -l /dev/console /dev/ttyS0
crw--w--w- 1 root root 5, 1 Jul 8 07:19 /dev/console
crw--w--w- 1 root root 4, 64 Apr 13 08:39 /dev/ttyS0
I also have to give the command boot option:
console=/dev/ttyS0
Now it works. Good Luck.

of course the root fs has been mounted. maybe there is something wrong with your shell or
execve() itself.
there is a sequence of execve() at the end of init() and if all these calling fail, a message
will be shown as : 'No init found. Try passing init= option to kernel.'
w.y.
