Even if this is violating the ACPI spec, any fix for this needs to be
tested on the hardware (and I can very well imagine that the hardware
might be violating the spec too, nothing new here).

So even if you had a fix, you need to run it on the hardware to verify
that it actually works.

So the actual practical question turns into: do you have such hardware
to verify your or anyone else's fix on?

Thanks.
