The log you attached showed the amdgpu drm driver being used, so it was
deployed.

So no configuration change in your side.

Erm, it's not clear "how" you triggered the suspend and resumed.  By the lid
close (if laptop), from KDE menu, or whatever?  Just to be sure.

Also, do I understand correct that you're dealing with the suspend-to-RAM, not
the hibernation, right?

Thanks!

The old log showed that it was 5.7.x kernel.  Could you try to install the old
kernel from OBS home:tiwai:5.7 repo, boot with it and test the suspend/resume?
