Comment 33 for bug 1348890

Here is this bug reported upstream by me: https://bugzilla.kernel.org/show_bug.cgi?id=92391
It was closed as duplicate with a reference to this one: https://bugs.freedesktop.org/show_bug.cgi?id=81762

It is not a problem with device initialization, it is rather a problem with device driver not initializing some fields in device op.region with a values expected by ACPI code. There was an experimental kernel branch which is expected to fix this bug but I'm not certain what is current status on this. Looks like there is next to none activity in DRM/Intel bugzilla report #81762 so chances seem to be low that we would get a proper fix anytime soon.
