--- 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
0x7f9e326d3000+0x17305
 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
/etc/X11/xorg.conf:

Section "ServerFlags"
       Option  "AutoAddGPU" "off"
EndSection
