Ah, you're on bleeding edge HW. Stopping showing off!
It's an AMD Radeon HD 7770 1GB. The audio is not in use but I'm including it
just in case.

I'll be attaching two logs. One of them from a few days ago where the GPU
managed to recover (if we can call that "recover" it was barely functional and
had to reset via Ctrl+Alt+Supr). Another from today I just repro again and was
totally unable to recover, screen flashed several times as if it tried to soft
reset more than once (I'm not certain that's what happened), still could do
Ctrl+Alt+Supr to reset.
I've been thinking these few days this bug MIGHT be related (causing):
https://bugs.freedesktop.org/show_bug.cgi?id=93649
If the game for just one frame randomly presents an invalid setup for one
measly small object, it would hang Radeon 7770s but it would work fine for
everybody else including these users in Windows (seriously, in my own program I
could not visually tell what was missing, it was some small object in a cubemap
render used for reflections) and nobody would notice.
If you have a suspect on where I should look (i.e. you have Mesa code that
SHOULD be catching this incorrect setup but isn't; I can analyze why it's not
catching the error) I can insert a few printfs or hook gdb. As a graphics
programmer I have my pride to keep.
