--- Comment #7 from Rodrigo Vivi <rodrigo.vivi at gmail.com> ---
Is this a Hang or just an unrecoverable black screen? There is nothing in the
log that suggest a gpu hang or a panic...

what happens with latest kbl 1.01 dmc firmware? 

and without firmware completely? (removing the /lib/firmware/i915 and updating
the initrd)

Also it is i915.disable_power_well=0 instead of i915.power_well=0. Can you
please double check that?

But honestly my biggest suspecious is around Watermarks. Might be worth to test
this series: https://patchwork.freedesktop.org/series/5158/ Although it is
under development and not merged yet.

Thanks,
Rodrigo.
