I experience random freezes and crashes in the linux game "Thimbleweed Park". Sometimes the game freezes for a few seconds and then recovers, but ultimately always crashes; operating system (ubuntu 16.04 with kernel ) remains stable though.
Here is some more information:
4.4.0-72-generic #93-Ubuntu SMP Fri Mar 31 14:07:41 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
dmesg | grep i9
[ 1.210450] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device
[ 1.211732] [drm] Initialized i915 1.6.0 20151010 for 0000:00:02.0 on minor 0
There error I get from the game when it crashes is:
"intel_do_flush_locked failed: Input/output error"
In the kernel log I can see the following:
[ 561.854459] [drm] stuck on render ring
[ 561.855002] [drm] GPU HANG: ecode 6:0:0x85eeffb8, in ThimbleweedPark , reason: Ring hung, action: reset
[ 561.855004] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 561.855005] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 561.855006] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 561.855007] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[ 561.855008] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 561.856202] drm/i915: Resetting chip after gpu hang
I was told to also mention "SNB" in this context.
Attached is a API trace which (on my system) reproduces the problem (randomly, might need to be run a few times before crashing/freezing). I checked with the developers of the game, they said some other people would also have this problem, and they'd also love to see this fixed.
Thanks for further analysis and fixing this problem! Let me know if I can do anything to assist.

I tried your apitrace on 2 different CPU's (SNB and KBL)
didn't reproduce the issue 10.6.8 and 18.1.0 mesa versions.
Also checked 17.2.6 x32 mesa.
Could you please re-check on latest stable mesa versions? Also, would be nice to see the version of mesa, you had that time.
