--- Comment #13 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Still crashes to the AVX memcpy SIGBUS, both with Mesa 11.2 and today's git (on
up to date Ubuntu 16.04).

Easiest way to reproduce the crash is by switching between "high" and "ultra"
graphics options and resume the game.  Sometimes game crashes when doing the
switch, but if not, it will crash at least after clicking "Drive" button to
resume the game.

There's pulseaudio thread, something doing nanosleep, lot of semaphore wait
threads and the crashing thread:

----------------------------------

As none of the threads has anything going through Mesa, this looks more like
problem in the game itself,
