--- Comment #10 from Martin Andersen <martin.x.andersen at gmail.com> ---
Added two attachments, the first from a correctly-working 3.13.5 and the second
with a 4.0.9 kernel exhibiting the bug.

Steps performed after boot:

3.15.5:

$ xrandr -q
$ xrandr --output HDMI2 --rate 24       (HDMI2 switches refreshrate correctly)
$ xrandr --output HDMI2 --rate 23.976   (HDMI2 switches refreshrate correctly)


4.0.9:

$ xrandr -q
$ xrandr --output HDMI2 --rate 24       (blank screen on HDMI2)
$ xrandr --output HDMI2 --rate 23.976   (blank screen on HDMI2)
$ xrandr --output HDMI2 --rate 60       (display being output on HDMI2)
