Bug 111269

After the hang, the following can be observed in the dmesg log:

[  123.712426] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* Waiting for fences timed out or interrupted!
[  128.832311] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx_0.0.0 timeout, signaled seq=33035, emitted seq=33037
[  128.832350] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process RiseOfTheTombRa pid 4366 thread RiseOfTheT:cs0 pid 4380

I also tried attaching gdb to the game which tells me that there is indeed a thread that waits for the fence:

In the meantime another thread is busy creating a pipeline:

I have the exact same problem, with self-compiled mesa-19.2.0-rc1 and llvm from git (573d81cec5c3ed27e802e4e5ceb136330386a61d) on Fedora 30 with kernel 5.3.0-0.rc5.git0.1.fc31.x86_64.
