<pre>I am hitting this bug on Carrizo as well.
In particular, it only takes effect if the disabled output is the integrated
screen (eDP-1). Disabling the DP-1 output (which is actually an HDMI port)
connected to an external screen has no visible effects.
My system is Arch Linux, with the default kernel (Vanilla Linux 4.7.2 with a
one-line patch changing the default log level).
I can provide additional information about my system if necessary.
I can also try out kernel patches if that will help.</pre>
