Test of above with R9 380 with Windows 8.1 and latest AMD drivers

Hi,

After being asked to try this by Alex in IRC, I've added the output of the
various logs, there will be overlap in places, dmesg and messages.

I'm running 4.13.0-rc2 with drm-next-4.14 branch merged and the set of 3
patches from Alex. Tried with and without the third patch, I still get a black
screen on restarting the VM (using virt manager). The first boot from a freshly
booted host starts fine.

In the log I've put "START" and "RESTART" where the VM is started (then
shutdown) and then restarted. There is also extra PCI debugging messages
enabled in the kernel.

I too, would like an answer re the probing mentioned in 11.
