I followed this trace and proc_handler is correctly defined in tty_table

Additionally, we then fail trying to print instead of continuing with
the initialization. My conjecture is that this might be due to something
different than tht sysctl register call.

Does this happen consistenly or is this just a one off issue?

Don't know.

To what branch are these patches being applied to?

As far as I understand from 
https://github.com/linuxppc/linux-snowpatch/commits/snowpatch/375319, 
it's being applied on 
https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git/commit/?id=d774975

I'm going to post my V2 and keep working on this issue if it pops up
again.
