The latest kernel from yakkety-proposed does not appear to fix the problem. Note that I did test it on Xenial, not Yakkety, because I do not have an easy way to reproduce the bug that excercises rate-limited printk on Yakkety.

I made sure that the proposed kernel was used by comparing what is getting installed on Yakkety vs Xenial:

On Yakkety
==========

$ sudo apt-get install -y linux-image-generic/yakkety-proposed

Selected version '4.8.0.44.56' (Ubuntu:16.10/yakkety-proposed [ppc64el]) for 'linux-image-generic'
The following additional packages will be installed:
  crda iw libnl-3-200 libnl-genl-3-200 linux-firmware linux-image-4.8.0-44-generic
  linux-image-extra-4.8.0-44-generic wireless-regdb
Suggested packages:
  fdutils linux-doc-4.8.0 | linux-source-4.8.0 linux-tools linux-headers-4.8.0-44-generic

On Xenial
=========

And I was able to reproduce the printk spam on Xenial with the proposed kernel. Did the fix actually get into 4.8.0.44.56?
