dmesg

My laptop has an Intel CPU/iGPU + AMD dGPU
I compiled both the current master of 4.9 and drm-next-4.10-wip, I have the
same problem, when I try to use the m265x with "DRI_PRIME=1 glxgears"
everything freezes for about 5~10 seconds, then glxgears appears but the gears
are either frozen or I just get a black window. 
Then when I try to shutdown it never completely turn off and I have to force
the power off
I tried both with and without amdgpu.runpm=0 but I get the same behaviour.
