Comment 25 for bug 1853044

I believe lp:1863489 is a duplicate of this, but the symptom is powertop showing that the i915 device is not dropping into RC6 or lower power state. I was able to reproduce this on my laptop and after installing the above 5.3 test kernel, powertop is now showing RC6 usage > 90% when my desktop is idle.

The 5.3 test kernel Seth generated worked for me. I also tried the 5.4 test kernel Andrea built which also showed RC6 usage > 90% via powertop.
