I have root access to all powerpc/ppc64 machines (buildds and porterbox).

I'm cleaning up the porterbox now, disk is quite full, then you can try
to build the kernel package on perotto.debian.net or I can try it myself.

I have seen the bug myself and I wanted to debug it, but the attempt was
foiled by the fact that the disk on perotto is full (again).

Will take care of it and let you know when it's (some hours).

Adrian
