<pre>Seems like this is a regression actually. I've managed bisect the commit which
caused the problems.

commit to be able to compile the kernel, but judging by the changes the merge
commit was the one that broke it.
Some more details:
1) Disabling/enabling FreeSync doesn't matter
2) Issue happens under Xorg KDE/Wayland Gnome/Xorg GNOME
3) HDMI or DP doesn't matter
I'd try to narrow it down to the exact part of the commit that causes the
issue, but I am having an issue with my Ryzen soft locking thread by thread
until a complete lockup happens when compiling with 16 threads.</pre>
