logs of

(copy of https://bugzilla.kernel.org/show_bug.cgi?id=176351)

When resuming from hibernate state, kernel linux 4.8.0, the screen is
blank(acpi off) and it does not resume. Previous version 4.6.0 works fine,
resuming screen is blank (acpi off), pressing a key screen it switch on, all
right.

I done two test, first resume worked (restart after few seconds), second failed
(restart after a while). In attach logs of both cases.

In the attached file I can see following:
