--- Comment #2 from pac12referee at gmail.com ---
I updated the kernel to 3.16.0-031600-generic, and it failed again, however
recovered and Cinnamon went into fallback mode.  Although, when I tried to
restart Cinnamon, it kept going into fallback mode.

Will upload latest /sys/class/drm/card0/error.

$ dmesg -T | tail -8
