r346352 was done exactly to fix G7 issues.  It might be G8, but still should be very close.

To make any progress with this, re-check with HEAD.  If the results are similar, provide acpidump -dt output.

(In reply to Konstantin Belousov from comment #3)

In r346352 I reading: "MFC after:	1 week"

Can you bring it to 12-STABLE ?
I do not have the opportunity to update FreeBSD to HEAD on this server.
