With the AMD RX460: The commit 7aadd3abc1eedef97fc89adf6bf4602b224af890 - "drm/amdgpu: Fix amdgpu_sync_add_later to preserve explicit flag" cherry picked into drm-next-4.16 allows the glmark2 test to run until the end, otherwise it will deadlock immediately at the start of glmark2 terrain test. The tested mesa version is from the master branch at commit5e1cb16768d3b97724ab85fbc50119dd8c9281c0 - "anv: fix a case statement in GetMemoryFdPropertiesKHR". Random deadlocks still occur at diverse occasions and with diverse applications. The stack trace remains similar to the one reported in the original email. I've also tested an AMD R7 240 and it is producing system freezes since several months ago up to the present moment, while playing video, they are not deadlocks as the kernel completely freezes, not just applications.
