PB G4 12" power-down during debian kernel boot for install
(yes, the laptop is plugged in and has a full battery ;) )
Basically certain kernels can boot, but the others I have tried to use
begin to boot, then the powerbook powers-down.
According to this helpful page by Matthias Schmidt:
http://www.mathematik.uni-marburg.de/~schmidtm/apple/powerbook.en.php
I need to use "the kernel from Orion Buckminster Montoya, which I
renamed to linux.bin. You have to take his kernel, because the debian
default kernel doesn't support ATA 100. The ATA chipset is the
"intrepid chipset, which is UniNorth bridge and KeyLargo IS ASIC merged
in one chip.""
Orion Buckminster Montoya's kernel (it appears to be a recomplied
2-4-20ben5 with ATA100 support for all known chipsets):

I did try the normal install kernel, from
http://http.us.debian.org/debian/dists/woody/main/disks-powerpc/
current/new-powermac/
It booted fine, and guess what! I couldn't see the hard drive, exactly
as expected (no ATA 100 support).
Booting was done from one of my HFS volumes.
When trying to boot into the debian install system, I can get the
kernel loading from yaboot 1.3.10, and then I get:

<at this point (about 1.5-2 seconds into the kernel boot) (before tux
appears) the laptop abruptly powers down.>
The above was as best as I could make it out, but since the whole thing
just turns off after a few sec, I had to reboot about 20 times to write
it down. (It made me feel like I was shortening the life of the PB
through torture, but everything still seems to work fine in OSX after
all that.)
This leads me to believe that the kernel & or firmware is the issue,
and not my hardware... but this problem is not new to me..
Background...
This problem first cropped up when I was running YDL, and
_accidentally_ :( installed the 10.2.8 OSX update on another (OSX)
partition. (This apparently also did a firmware upgrade, and a few
folks on one of the YDL lists also found their PB G4 12" Linux systems
unbootable after the update and people had to re-complie their kernels
(i think it was a benh one) to get them to boot {searched their lists
but couldn't find it] ) I didn't have another system capable of
building a kernel nor did I have a way to get it onto the ext2
partition. In the case of YDL the symptom was almost identical except
it happened maybe 1 second earlier, right after OF's "quiescing(sp)"
line. The kernel I was using then was vmlinux-2.4.20-8d. Back in the
fall, I basically wrote the partition and install off.
I had used the YDL as my primary workspace and had Mac On Linux running
for certain OSX apps. OSX couldn't even see the ext2 partition, and I
had to use this utility to mount the ext2 partition: Ext2FS_1.1b1.dmg
(a bit funky, but let me mount and recover my files from the ext2
partition, plus gave me some command line goodies for ext2 in OS X)

I also used yaboot to try booting from the ext2 partition and achieved
the same results as above.
I also used yaboot to try booting from the existing Apple_bootstrap
partition (old YDL) and met with the same results as above.
System: powerbook G4 12" 867Mhz

YDL (broken)-> now trying to replace it with Debian.
Anyone have a kernel that will boot me into the Debian installation
w/ATA100 support or any ideas on what the heck is happening here?
Sorry for the long post
Thanks again,
