--- Comment #13 from Andrey Arapov (andrey.arapov@nixaid.com) --- Could you please try reverting this commit https://github.com/torvalds/linux/commit/e03fd3f300f6184c1264186a4c815e93bf6... , rebuilding your kernel and let us know if it fixes your issue?
Not sure if your problem is related to mine here https://github.com/Dunedan/mbp-2016-linux/issues/73#issuecomment-422397681
But it has helped in my case.
