I want to be clear, this bug does not just affect Ryzen series CPUs/APUs, it also affects the previous gen CPUs, including the FX9800P in my x360, model m6-ar004dx. It looks like they share the same GPIO config with respect to the i2c ELAN0734 touchscreen controller.
I would like to make sure whatever fix gets put in fixes all affected platforms, not just Ryzen. I will gladly test driver/kernel patches and/or ACPI/DSDT patches. I can also post my DSDT if it helps, it was very similar with regard to this GPIO to the one already discussed.
I have two identical laptops I can test with.
