I am not a kernel maintainer (and at least one bug that I see is
somewhere in mesa and there is a bug tracked by upstream there, I don't
remember the link though).
But - I have the same issues and for me the following things make it
work:

➜  ~ cat /etc/modprobe.d/99-amdgpu-overdrive.conf
options amdgpu ppfeaturemask=0xFFFDFFFF dcdebugmask=0x10
➜  ~

you need to run `update-initramfs -u` after adding the file.
That will also allow lact to tune the gpu frequencies.

https://github.com/ilya-zlobintsev/LACT - not in debian unfortunately,
but there are packages in the github releases.

I had to limit the speed of my card so its actually within its specs,
current drivers want to boost it even higher than my overclocking-
supported card accepts. Be aware that you might be able to brick your
card using that too.



Hope that helps,

Bernd
