I think you have to dig more on new kernel 4.12.1, because before I didn't observe any issue at all
Hope it helps

We had 8 test releases for 4.12 (one for each release candidate, plus 4.12.0 as the cutover to the new kernel was delayed by an nvidia driver issue) - can you try the Generic builds linked in PR:1629 as that should help narrow it down further.
