Public bug reported:

in Ubuntu 14.10 (powerpc) ofpath generates incorrect OpenFIrmware device
path. This path is used in yaboot.conf and in ofboot.b

Because of this issue, system will not boot. The problem happens during
install procedure and after otherwise sucessful installation system
fails to boot.

Most likely (but not directly verified) the issue is already present in
Ubuntu 14.04

ifpath returns:
ofpath /dev/sdb
/ht@0,f2000000/pci@9/k2-sata-root@c/@ffffffffffffffff/@0

while OF wants:
/ht@0,f2000000/pci@9/k2-sata-root@c/k2-sata@1/disk@0


Kernel got it right:
/proc/device-tree/ht@0,f2000000/pci@9/k2-sata-root@c/k2-sata@1/disk@0
