Bug#369448: linux-image-2.6.16-2-powerpc: package fails to install

[Michael Furr <furr@cs.umd.edu>]

Package: linux-image-2.6.16-2-powerpc
Severity: grave
Justification: renders package unusable

I recently started booting my TiBook into linux again after not using it
for a while.  It was running 2.6.8 and after running into the well-known
udev problems, I now have a self built 2.6.16 kernel and the lastest udev
running.  However, when I now try to install the stock Debian kernel, it
fails:

A package failed to install.  Trying to recover:

I've tried looking through the preinst, but I'm not sure what is going
wrong since there isn't much in the way of an error message.  Since it
seems to start by setting up the initrd, I tried both initramfs-tools and
yaird (after setting the ramdisk option in /etc/kernel-img.conf) just in
case.  However, I still get the same error.

Any ideas?
