Description

The display Manager,part of the desktop and any graphics app i run get severe artifacts on any kernel 4.11.x version with amdgpu enabled, whereas in 4.10.17 all is working good.

Reproduce:

Install kernel 4.11 and later with SIK=y, blacklist radeon, install xf86-amdgpu, enable the amdgpu module and boot the kernel.


Same regression existed in kernels 4.10.2 and lower but was fixed after the 4.10.3 update
