<pre>I can confirm that the patch in <a href="show_bug.cgi?id=94161#c28">comment 28</a> (Use WaRsDisableCoarsePowerGating)
solved the issue on my Intel NUC6i5 with only a moderate increase in power
consumption.
With an idle desktop using kernel 4.6.0-rc3, the system consumes:
7 Watts without patch, RC6 enabled, frequent crashes
17 Watts with i915.enable_rc6=0, no crashes
9 Watts with patch, no crashes</pre>
