With the recent amdgpu-pro driver i experience some problems, which i hope one of the developers can take a look at:
The dmesg / kern.log will be spammed by VM exceptions when the gpu is in use.
When i run the heaven benchmark it locks up the X server. The system itself is still running then.
When the gpu memory is exhausted it locks up the whole system. The offending program should get an exception and it should not lock up the whole system.
Also there are the black screen on boot issues..
