--- Comment #18 from Diego Viola <diego.viola at gmail.com> ---
I tried some older kernels in order to see if this ever worked before, and to
see if I could bisect the problem.

The kernels I tried:

4.10.17
4.9.33
4.8.17
4.7.10
4.4.73

Those are all broken, which means the bug is also present in those too.

4.8.17 and 4.7.10 I couldn't even get to compile due to this error:

kernel/built-in.o: In function `update_wall_time':
(.text+0x7afd7): undefined reference to `____ilog2_NaN'
make: *** [Makefile:969: vmlinux] Error 1

I'm sure 4.6 and 4.5 would have been the same.

4.4.73 is also broken, which means the game ran and but it hung, I didn't
notice any 'flip_done timed out' errors in dmesg, the game window just got
frozen/stuck and after I closed the game window (ctrl-c on the process), and
restarted the game, the whole system froze and the display turned black. I had
to hard reset at this point.

So maybe it never worked and there's no way for me to bisect.
