I have not seen any discussion. As the initial reporter, I can accept
that it is a very niche hardware platform and may well go unfixed
forever. The machine in question has left my possession. It may come
back in the future. Or maybe not. The next-generation newer ppc64
machine I have (an IBM 8205-E6C p740) does not exhibit this behavior.

I didn't check mainline specifically, no. All bisection was done
against the stable git repo.

Thanks!
