Reboot fails on initial installation - yaboot, Handbook 10f

[sirtisimacg4]

I'm following the PPC installation handbook to install on my iMac G4. My attempt to reboot results in:

boot: Linux
/pci@f2000000/mac-io@17/ata-4@1f000/disk@0:7, /boot/kernel-genkernel-ppc-3.10.7-gentoo-r1: Unknown or corrupt filesystem

I'm using a G4 imac with the following partitions added:

/dev/hda5 Apple_Bootstrap bootstrap NewWorld bootblock
/dev/hda6 Apple_UNIX_SVR2 swap Linux swap
/dev/hda7 Apple_UNIX_SVR2 root Linux native

fstab is

/dev/hda7 / ext4 noatime 0 1
/dev/hda6 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto noauto,user 0 0
/dev/fd0 /mnt/floppy auto noauto,user 0 0

yaboot.config is

boot=/dev/hda5
device=/pci@f2000000/mac-io@17/ata-4@1f000/disk@0
partition=7
root=/dev/hda7 rootfstype=ext4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/kernel-genkernel-ppc-3.10.7-gentoo-r1
label = Linux
read-only
initrd=/boot/initramfs-genkernel-ppc-3.10.7-gentoo-r1
initrd-size=8192

Any ideas?

You need to tell the kernel to boot your root partition, dev/hda7

So, in my search for a solution I'm finding that yaboot doesn't understand ext4 - which is the file system where my kernel is. I guess that means I need to create a boot partition in ext2 or ext3. Oh well ... back to step 4. It would have been nice if the installation guide had mentioned that before step 4.

I changed my root filesystem from ext4 to ext3 (starting from step 4 again), did a manual configuration (step 7b) instead of genkernel this time, ran yabootconfig in step 10 ... rebooted ... and got exactly the same result (except not with genkernal this time):

boot: Linux
/pci@f2000000/mac-io@17/ata-4@1f000/disk@0:7, /boot/3.10.7-gentoo-r1: Unknown or corrupt filesystem

I'm using yaboot-1.3.17-r2

I searched the forum and found an earlier post with a similar problem that was fixed by going back to yaboot-1.3.16-r1, but I don't know how to install earlier versions of anything.

Any suggestions?

I was able to boot, after yaboot failed to boot automatically, by entering the path manually:
