THANK YOU

Now it works. Looks like the DC code was causing troubles.

This is my current configuration for grub
GRUB_CMDLINE_LINUX_DEFAULT=3D"radeon.cik_support=3D0 amdgpu.cik_suppor=
t=3D1
amdgpu.modeset=3D1 amdgpu.dc=3D0 amdgpu.dpm=3D1"
I'm on kernel 4.18.3.

I left the PC running for hours and it didn't freeze. This was simply
impossible before the new changes.

I also tried reducing the monitor shutdown to 1 minute, and it worked every
single time I left it idle.

I think that I can finally confirm I'm no longer able to reproduce this bug,
after 2 and a half years of using this card, and trying new kernels once a
month.
