--- Comment #6 from Johannes Hirte (johannes.hirte at datenkhaos.de) ---
Some more observation: It seems the hangs happen much more often/frequent with
kernel 4.11 than with 4.10. Where 4.10 kernels running usually several days, I
have a hang with 4.11 within a day.

Additionally I've found some of the 

WARNING: CPU: 1 PID: 872 at ./include/linux/dma-fence.h:349 amdgpu_vm_grab_id 

entries in the logs without a hang at this time. As far as I've seen this was
always with a 4.10 kernel.
