dmesg with kernel amd-staging-4.17-wip-c6bcaec0aa3e

OK, so on boot everything seems fine and dandy, less error messages than
before. 

However, please note the 213.xxx and 480.xxx marks: This is where I actually
use the dGPU (with DRI_PRIME=1 glxinfo). Something is clearly not right here...

Also, power consumption as per powertop has not improved over 4.15/16, the dGPU
clearly does not fully power down when not in use (~25W vs ~12W with amdgpu
blacklisted).
