Bug 107221

Hi,

While running IGT tests on an Intel KBL-g based platform (which apparently has a VEGAm AMD GPU), we get the following messages in dmesg:

[  225.881278] [drm:vce_v3_0_set_powergating_state [amdgpu]] *ERROR* VCE not responding, trying to reset the ECPU!!![  22

Here is an example of full logs:
