Bug 103962

Created attachment 135785 [details]
relevant dmesg output

I am testing the new DC code with 4.15-rc1 on my Alienware 15R3 with an RX470 dGPU.

This machine has forever had the problem that pm will not turn the dGPU off properly when it is not in use, thus causing heat and battery life issues. I had hoped that maybe the DC code would help here, but it seems to just have switched the kinds of error messages I get around. Here are the new ones, I keep getting a bunch of:
