            Bug ID: 107855
           Summary: [regression] [amdgpu] [drm:vce_v2_0_start [amdgpu]]
                    *ERROR* VCE not responding, giving up!!!
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: graaskaeg.via.forwarder@neverbox.com

kernel 4.18.0-041800-generic on AMD A10 (Kaveri)
kernel boot parameters:
amdgpu.cik_support=1 
radeon.cik_support=0 
amdgpu.dc=1 
amdgpu.dc_log=1 
drm.debug=0

Laptop has HDMI, VGA and internal eDP.

Using amdgpu.dc=1 to force use of amdgpu instead of radeon driver. This means
VGA connection is expected to be inoperative. (See bug 105880)

dmesg show Video Coding Engine (VCE) is not successfully starting

The laptop screen remains blank, and the cpu fan ramps up. I used the 'magic
SysRq' key combination followed by R E I whereupon it was possible to get to
the first virtual console (Ctrl-Alt-F1) and save the dmesg ring buffer.

kernel 4.17.0-041700 generic does not show this behaviour, and the laptop
screen works, allowing X-Windows login.
