Bug#260433: Power4 fails to boot install kernel

[Jake Moilanen <moilanen@austin.ibm.com>]

Package: installation-reports
Version: sarge-netinstall powerpc 20040718

architecture:  powerpc 
model:         JS20 Blade
memory:        2 Gig
scsi:          none
cd-rom:        USB over ISD200
network card:  broadcom 5704
pcmcia:        none

I tried using the sarge netinstall for powerpc on a Power 4 box and ran
into a number of problems.  If you want me to break these into separate
bug reports, I can.  It's just a hassle.

- yaboot.conf is not located at /etc/yaboot.conf.  If you are booting a
chrp box, yaboot expects yaboot.conf to be at /etc/yaboot.conf.  I got
around this problem by doing a hardlink.

- The device in yaboot.conf is set to 'cd' and newer versions of
firmware for ppc64 RS6000 have the name 'cdrom', thus it couldn't find
any of the kernels or boot.msg files on the disc image.

- The power4 kernels will cause a default catch in open firmware when
booted.  I'm not sure exactly how the power4 kernels are being built,
but every ppc64 box I tried they failed to boot.

I also looked at the compressed kernels w/ the initrd attached without
luck.  When I did a hexdump on them, the headers looked much different
from a kernel image that I got booting w/ the debian intaller attached.


Here is a non-bootable image that is currently being built:

	# objdump -h vmlinuz-chrp.initrd

Here is a version I built that works:
