dmesg from boot
Booting Linux 4.6-rc1 and Mesa 11.2/11.3 fails to load the nouveau driver on a
GTX 970M (6GB) on an MSI GS60 Ghost Pro 4K (i7-6700HQ). It spews out wonderful
messages like

Attached is a dmesg from boot. The driver does just drop to the i915 driver so
the machine is usable, but whenever I run lspci or lshw or try to logout of the
X session, it hangs when it switches back to the nVidia GPU (the laptop has an
LED indicator showing which GPU is in use)</pre>
