[Bug 51080] kernel fails to fully boot

[Gary Elshaw]

Public bug reported:

Binary package hint: linux-image-2.6.15-25-powerpc

I've been through a major odyssey with the transition from Breezy to
Dapper, mostly on account of the kernel problems i encountered during
Dapper's development:

https://launchpad.net/distros/ubuntu....15/+bug/34508

Here is the pre-reboot method i ran through to get a working install:
Clean install Breezy --> dist-upgrade to Dapper via distribution
installer CD --> updated all packages via synaptic --> removed quiet
splash options + ybin -v --> removed old Dapper distribution kernel and
i set the old Breezy kernel for 'old' as a boot option that works.

Attempting to boot the latest kernel (.43) grinds to a halt at one of
two places:

hda: cache flushes supported
hda: [mac] hda1 hda hda3 hda4 hda5 hdb6

OR

hdb: cache flushes supported
hdb: [mac] hdb1 hdb2 hdb3 hdb4 hdb5 hdb6

This is my yaboot.conf, just in case this might help.
