All this setup worked fine in a previous kernel versions, IIRC, 4.11 and below
and started to fail in 4.12 and above

I also notice that the dedicated card switch fron DynOff to DynPwr in
/sys/kernel/debug/vgaswitcheroo/switch for a few seconds when trying to run the
glxgears


Finally, If i boot the system with radeon.runpm=1, it works

Let me know if you need more logs
