--- Comment #4 from Christian König (christian.koenig@amd.com) --- This is expected behavior, your application tries to use more memory than physical available:
[71804.930003] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Not enough memory for command submission!
That is most likely a bug in the application, e.g. a memory leak.
