Created attachment 204947 [details] dmesg without hw.dmar.enable=1
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.
(In reply to Dmitry Luhtionov from comment #4) The referenced commit was merged to stable/12 in r346663. Is there anything left to do for this PR?
