--- Comment From wil...@us.ibm.com 2016-01-15 12:39 EDT---
I was finally able to install and boot the new kernel with:
sudo apt-get install linux-image-generic
$ uname -a
Linux z1381 4.2.0-24-generic #29-Ubuntu SMP Mon Jan 11 17:59:07 UTC 2016 
ppc64le ppc64le ppc64le GNU/Linux

However I don't see the my patch in this kernel.  After upgrading the kernel I 
did this to get the source:
$apt-get source linux-image-
The resultant source is missing my patch.

In comment 71 of the bug it implies that the patch was added on 1/13 (maybe).
The kernel I installed was build 1/11.  So maybe I am still not running the 
correct kernel.
Any ideas?
