Comment 169 for bug 1803179

I've tryed the patches and can confirm that the issues with lockups are gone with just using bumblebee (unloading nvidia module).

But still the problems are the same:
1.) Just unloading the nvidia modules keeps the power consumption up to 13/14W which is 5-6W more (almoest double) in compare to intel only ~8W

2.) Using acpi call to poweroff the nvidia card completely which drops the power consumption to 8W the lockups are back.

So for me the patches are not working :(
