--- Comment #2 from Brad Garcia <bradgarcia at gmail.com> ---
With 4.4rc2 installed, I am still able to reproduce the problem.  Behavior is
exactly the same.

Installed 4.4rc2 as package by phoronix.
https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.4-rc2-Spun-For-Ubuntu

Confirmed that it is running:
$ cat /proc/version
Linux version 4.4.0-rc2-phoronix (phoronix at phoronix-To-be-filled-by-O-E-M) (gcc
version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2) ) #4 SMP Mon Nov 23 10:03:29
