--- Comment #7 from Daniel Scharrer daniel@constexpr.org --- (In reply to Michel Dänzer from comment #3)
Does the environment variable R600_DEBUG=nodma avoid this problem?
No change here either. But now that you mention it: IIRC SS3 did sometimes lock up the GPU before http://cgit.freedesktop.org/mesa/mesa/commit/?id=ae4536b4f71cbe76230ea7edc7e...

Can you generate an apitrace which reproduces the Packet0 error and/or GPUVM faults?
Here is one with VM faults from starting The Talos Principle Public Test, just up to the main menu:
http://constexpr.org/tmp/Talos_Demo.trace (149 MiB)
Sometimes there is also a Packet0 error at the end. Didn't get it while recording, got it 2/3 times while replaying.
