journal_from_boot_to_HDMI_cable_detaching

We are working with new laptops that have the AMD Bristol Ridge
chipset with this SoC:

AMD A10-9620P RADEON R5, 10 COMPUTE CORES 4C+6G

When the HDMI cable is attached and then detached, the internal panel goes
black and the only way to have it back is switching to another TTY and then
back to xorg or doing 'xset dpms force off; xset dpms force on'.

This is reproducible also on the ~agd5f/drm-next-4.13-wip branch.

In the attachment the whole journal when booting the kernel compiled from
~agd5f/drm-next-4.13-wip, landing in xorg and then attaching and detaching =
the
HDMI cable.
