I installed Debian lenny recently and had a similar problem. It turned
out to be a problem in yaboot.conf in the NewWorld bootblock partition,
/dev/sda2 in my case. I'll report here what I did to get the G5 up and
running with Debian lenny.
After I installed Debian lenny, I used the install CD a second time to
run a shell.
N.b. The problem I had may not be the same you're having now.
1. List your system disk partition table
fdisk -l /dev/sda
/dev/sda
# type name length base (
size ) system
/dev/sda1 Apple_partition_map Apple 63 @ 1 (
31.5k) Partition map
/dev/sda2 Apple_Bootstrap untitled 1954 @ 64
(977.0k) NewWorld bootblock
/dev/sda3 Apple_UNIX_SVR2 debian 155078126 @ 2018 (
73.9G) Linux native
/dev/sda4 Apple_UNIX_SVR2 swap 1232432 @ 155080144
(601.8M) Linux swap
Block size=512, Number of Blocks=156312576
DeviceType=0x0, DeviceId=0x0
2. Mount the NewWorld bootblock partition
mount -t hfs /dev/sda2 /mnt
3. Make a save copy of /mnt/yaboot.conf
cp -p /mnt/yaboot.conf /mnt/yaboot.conf.orig
4. This is my yaboot.conf.orig
cat /mnt/yaboot.conf.orig
## yaboot.conf generated by debian-installer
##
## run: "man yaboot.conf" for details. Do not make changes until you have!!
## see also: /usr/share/doc/yaboot/examples for example configurations.
##
## For a dual-boot menu, add one or more of:

boot=/dev/sda2
device=/d...@0:
partition=3

label=Linux
read-only
initrd=/boot/initrd.img
image=/boot/vmlinux.old
label=old
read-only
initrd=/boot/initrd.img.old
5. I manually applied the following changes to yaboot.conf by using
'nano /mnt/yaboot.conf'
diff -up /mnt/yaboot.conf.orig /mnt/yaboot.conf
