Savegame in Velen

System:
Ryzen 5
AMD RX 560

Arch Linux
Linux 4.11.7
MESA 17.1.4
AMDGPU 1.3.0
wine-staging 2.11

I've had great success playing The Witcher 3 using wine-staging 2.11.
I managed to play about ten hours in the area called White Orchard.
After moving on to the area called Velen I pretty soon encountered a system
freeze that is reproducible every time.

When the freeze happens the in-game music keeps playing.
I can sometimes switch to TTY1 but afterwards the system reacts to nothing and
the music stops. A hard reset is the only option. A savegame in the area where
this happens is attached.
Just turn left and run towards the cart. This freezes my system reliably.
