I can confirm that the patch in comment 28 (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
