            Bug ID: 100591
           Summary: [AMD APU A9-9410] Kernel hang when using graphics
                    acceleration
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: ben.davenportray at gmail.com

Kernel hangs hard whenever it has to do anything graphics accelerated or too
cpu intensive (two laravel web server instances / opening chromium / opening
YouTube on Firefox / I look at it too hard). It won't even let me switch to
another console, forcing me to hard reboot. 

I am unable to see anything using `journalctl -xe` when my system goes down;
either the log just stops or the file is corrupted, though I also don't know
what I am looking for. 

I was able to confirm that it wasn't thermal overheating, and chip diagnostics
say that it is okay. 

Linux 4.9.20
xorg-xserver 1.19.2
