dmesg with 4.17-wip-7f462340284582c0180384c046ddd6dda03888b1 and dc=1

I have rebuilt with the latest commits to 4.17-wip (up to      
7f462340284582c0180384c046ddd6dda03888b1) and lo and behold: I was able to run
my usual DRI_PRIME=1 glxgears *without* the system crashing afterwards. So that
is quite a bit of progress. PM also seems to work, as battery drain is around
11W while composing this message, and noticeably higher only when explicitly
invoking the dGPU. Will test with dc=0 soon.
