--- Comment #41 from Mathias Tillman <master.homer at gmail.com> ---
Just tried it again with the latest drm-next-4.4 and the kernel parameters
amdgpu.enable_scheduler=0 amdgpu.vm_debug=1 amdgpu.enable_semaphores=1. Can't
even make it to the beginning of the test (it hangs on the loading screen, if
not before that - I have OpenGL acceleration enabled in kwin) when vm_debug=1
before hanging with a bunch of VM faults. If I set vm_debug to 0 it at least
starts properly.
Not sure if that was the intended behaviour, but that's what happens in any
case.
