<pre>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
<a href="https://www.x.org/wiki/Development/Documentation/ServerDebugging/">https://www.x.org/wiki/Development/Documentation/ServerDebugging/</a>), 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</pre>
