output for the previous v2 patch

Progress! It doesn't crash this time! And I finally have access to my laptop's
backlight again and can turn it off!! :P I applied the patch manually against
my kernel version 4.18.5 (and left the previous patches in as well, eg. the 5
second delay). However, it seems to get into a loop, where every ~10s it tries
to "intel_tv_detect" something. And I can't unload the module - it says that
intel_gtt is being used. I also notice a kernel trace in the logs beginning
with "vblank not available on crtc 0". (Thank you!)
