[pocket-linux] Kernel panic - Attempted to kill init

[M. Oujesky]

Hi,

I'm trying to build my own customized pocket linux, not so exactly by
the book, with some differencies (single boot/root diskette, busybox).
I hope, that someone will help me with this problem, although I'm doing
something not explained in the guide.

After one heavy hacking night I managed to create a boot diskette with
custom 2.6.11.2 kernel and compressed root image with busybox 1.0 packed
with UPX), which is situated after the boot section of diskette (block
850 exactly, kernel is booting with ramdisk_start=850 parameter) . I
managed to kill few error messages, but every time a new appeared. And
that last is too big for me...

Well, what is happenig. The grub loads kernel, kernel initializes, find
and load compressed root image to ramdisk, then throw kernel panic:

...
RAMDISK: Compressed image found at block 850
VFS: Mounted root (ext2 filesystem) readonly.
Freeing unused kernel memory: foo k freed
Kernel panic - not syncing: Attempted to kill init.

I'm not much familiar with kernel and his error messages, but I suppose
that anything that kernel calls as init ends before it can do whatever
is expected to do. I tried passing init= parameter to kernel with
/bin/sh and /sbin/init but both with the same result.

I'm thinking about few possibilities about what's wrong.
1) the root compressed image is bad (this is not much likely, because I
    tried standalone root disk with same result)?
2) the symlinks to busybox (sh, init etc.) can't be used to be called
    from kernel (this is too not much likely, because i tried staticaly
    compiled bash, as in the guide, and with the  bloody same result)?
3) the kernel is missing some feature, which I turned off to make him
    smaller?
4) the busybox or bash is compiled when running older kernel (2.6.10
    which I have in my Debian box), and cannot run with the one on the
    diskette?
5) something else...?

I'm testing on two boxes, Athlon 650 and AMD 5x86 133, but with no
difference.

I really appreciate anything that could help me to solve this. Thanks
much in advance.

Regards,
Mirek
