So first of all Hans posted this:

https://patchwork.kernel.org/project/linux-acpi/patch/20231006123304.32686-1-hdegoede@redhat.com/

and I'm wondering if it addresses the problem for you too.

If it doesn't, the patch will need to be rebased on top of the new
acpi-resource material in linux-next and retested.

Thanks!
