dmesg output

Using Arch Linux and kernel 4.8.3, I am observing much higher power usage in
powertop when using Nouveau with vgaswitcharoo (~13W) opposed to
NVIDIA/Bumblebee with BBSwitch (~7.5 W).

I initially started noticing this because the battery drained much faster and
the fans started to spin while they otherwise stayed idle.

Attached is my dmesg log.
