The preset I'm using is 'Medium', in 1920x1080. The hang seem to happen very
often (or maybe every time when the game was never launched before) at the very
beginning of the game (when Jonas catch Lara when she jumps after the very
first fall).

dmesg:

FYI I tried to start bisecting from mesa 17.3.5 but could not get very far due
to compilation issues (maybe related to llvm, not sure, I'm trying again).
