--- Comment #9 from Rong Zhang (i@rong.moe) ---
Thanks for testing.

I've just checked the decompiled ASL code of PNP0D80 (in SSDT4). Nothing stands
out, and the S0ix implementation seems appropriate.

The next thing that caught my eye was the "Failed to deactivate keyboard on
isa0060/serio0" error. Some devices can't handle this properly and will run
into a broken state. I am not sure whether your device falls into this
category, so please recompile the kernel using the following patch and see if
it helps.
