--- Comment #45 from Harald Judt (h.judt@gmx.at) ---
Thanks for the new patches.

Applying attachment 303055 and
https://patchwork.kernel.org/project/dri-devel/patch/20221020103755.24058-2-tzimmermann@suse.de/
on linux-5.19.16 did seem to have an effect at first, but after a few cycles
(and I booted into Windows and then resumed Linux again, switching VTs to
another X session and consoles and back, then hibernated/resumed again) the
machine crashed at resume, with the screen not frozen but dead.

I will try the whole patchset, however it seems I will have to adapt it to
5.19.16 - which needs more work - or update to the latest kernel dev release
and then try to apply it on this.

I have not yet tried the last fix, which reverts the prefer_shadow setting for
hawaii.
