Bug Description
The 7th of september I lost my Xorg display on wily. I was always in failsafe mode.
I still could get openbox to run, which was still loading i915, but didn't consume any 3D/advanced instruction I thinK.
I didn't got too much time to go beyond.
As I got also a btrfs kernel dump message, so I checked my ram at least with memtest86+, all was OK.
Reverting to vivid allowed me to be back on unity.
Wily-amd64, kernel 4.2.0.7-

dmesg - warning when switching from X to tty
Using 4.2-rc4 on my Haswell laptop I get the warning you can see in the dmesg attached whenever I switch from X to tty. The same happens using 4.2-rc1.
This never happened before.
