--- Comment #1 from Vitaly Ostrosablin <tmp6154 at yandex.ru> ---
Before deadlock, nothing is printed to terminal. I've also attempted using
GALLIUM_HUD environment variable to display various information. There's
nothing unusual right before deadlock (no VRAM usage spike, no high GPU load,
etc). Deadlocks seem to be completely random (I see no relation between scene
complexity, CPU load, etc). I.e. it may deadlock both on idle scene and during
active physics simulation (in case of Tabletop Simulator). Looks like an AMD
GPU issue.

If additional info is needed, let me know.
