If you think this can be fixed with the *little* kernel dev knowledge
I have please point me at a starting place and I will dig into it.

Thanks for trying to fix it.

You got unlucky and pulled Linus' tree just after a cleanup series was
merged, but before all the bugs had been shaken out.

Au contraire, I felt lucky to have bumped into a bug. I would like to
find more :)

Hah, well, we have *plenty* :)

I keep a rough list of TODO/FIXME type things on github:

  https://github.com/linuxppc/linux/issues/


If there's anything there that you want to have a go at please feel
free. If you have questions you can either comment on the issues or mail
me and/or this list.

cheers
