I have hybrid graphics on Lenovo Ideapad 720 laptop (Intel i7 8550U and AMD RX
560), use amdgpu and i have randomly hangs with kernels > 5.0.13.

AMDGPU hangs on laptop returned from hibernate, but on latest time i go to
5.2.8 and now AMDGPU hangs on normal work (only suspend to ram, without
hibenates).
