Can you try running the game with the environment variable R600_DEBUG=check_vm

Please make sure there are debugging symbols for
/usr/lib/xorg/modules/dri/radeonsi_dri.so and get a backtrace again (and please
attach it instead of pasting it as a comment).

--- Comment #14 from Nicolai Hähnle <nhaehnle@gmail.com> ---
Your dmesg log has a non-standard timestamp format (the [....] prefix in each
line), which causes the debug handling in radeonsi to get tripped up. The
fastest way to make forward progress is for you to revert your dmesg timestamp
format to the default and repeat.

--- Comment #15 from bellamorte42@gmail.com ---
Well, I guess the definition of non-standard is relative.  I didn't change
anything, how ever it is, is the way it came.  So I'm not sure what to
'revert'.

--- Comment #16 from Michel Dänzer <michel@daenzer.net> ---
The non-standard behaviour must be due to a (distro?) patch to the kernel or
due to a non-standard kernel build .config setting.

--- Comment #17 from bellamorte42@gmail.com ---
I was using a non-standard kernel (ck patch set, BFS, BFQ) but I get the same
thing when I switch to the stock (Arch) kernel.  The leading spaces to align
the timestamps certainly makes the output more legible, so I would call it an
improvement.
