<p dir="ltr">As far as I understand, the patch disables power gating which is a very bad thing in terms of power usage so this is not a fix, just a temp workaround.</p>

        <pre>Compiled kernel 4.6 rc2 drm-intel-nightly with the Mika patch (<a href="https://bugs.freedesktop.org/show_bug.cgi?id=94161#c28" target="_blank">comment #28</a>) and
everything is working fine, no gpu hang at the moment (4 days testing).
Why this patch is not merged? Maybe because needs more testing?

Thanks Mika.</pre>
