It's been over 3 months since we reported this bug by email, over 6
weeks since we reported it on bugzilla, and still there has been no
meaningful diagnostics help from AMD. This follows a similar pattern
to what we have seen with other issues prior to this one.

What can we do so that this bug gets some attention from your team?

Secondarily https://bugs.freedesktop.org/show_bug.cgi?id=106228 is
another bug that needs attention. We have a growing number of consumer
platforms affected by this. When booted, the amdgpu screen brightness
value is incorrectly read back as 0, which systemd will then store on
shutdown. On next boot, it restores the very low brightness level.
This can reproduce out of the box on Fedora, Ubuntu, etc.

Thanks,
Daniel
