--- Comment #10 from Elio <elio.martinez.monroy at intel.com> ---
Testing with latest drm-tip , warnings related from i915_irq.c are not present
anymore.

Creating a physical swap partition with 4.14.0-rc6 commit bcee836, the problem
is not present anymore. 

Executing different S states including S0i3 without any kind of issues, even
with 4k Monitor attached.
