--- Comment #1 from Michel Dänzer <michel at daenzer.net> ---
Please also attach the corresponding dmesg output.

Please install the xserver-xorg-video-amdgpu-dbg package, attach a new Xorg log
file from running with that installed, and either get a backtrace with gdb (per
https://www.x.org/wiki/Development/Documentation/ServerDebugging/), or provide
the output of the following commands:

 addr2line -e /usr/lib/xorg/modules/drivers/amdgpu_drv.so
 addr2line -e /usr/lib/xorg/modules/drivers/amdgpu_drv.so 0x7f9e326d3000+0xedfd

For the time being, assuming there are no display connectors on the AMD GPU
(that you need to use), you can avoid the problem by putting this in

Section "ServerFlags"
       Option  "AutoAddGPU" "off"
