So the installation went OK, but the reboot failed.

This looks like a kernel issue to me, although it could also be something 
related to the bootloader or the initrd. Unfortunately there is very little 
powerpc knowledge inside the debian-installer team at the moment.

One thing you could try is to boot the installer again in rescue mode and 
rebuild the initrd (using update-initramfs -u) from a chroot of the 
installed system. You should also check that the kernel that was installed 
is the correct one for your system.

Maybe someone on the powerpc mailing list can help further.
If that does not work, I'd suggest contacting the powerpc kernel developers.

Please let us know if you find out anything.
