Description Robert 2017-10-22 17:46:19 UTC 
Team Fortress 2 is crashing quite often.  All it takes is a few minutes of play or a map switch/load.  This is what is being reported in dmesg:

I checked /sys/class/drm/card0/error and the last error report in that file does not appear to match this set of crashes.  The date was current, but the time was a few hours earlier.  dmesg consistently reported the same error with each crash.

Created attachment 133817 [details]
GPU dump file, CSGO dump file and dmesg output

CSGO crashed after playing ~2 hours in and out of matches.  The following was reported in dmesg:

[ 7987.649974] [drm] GPU HANG: ecode 9:0:0x86df7cf9, in csgo_linux64 [4947], reason: Hang on rcs, action: reset
[ 7987.649976] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 7987.649978] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 7987.649979] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 7987.649980] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Comment 1 Robert 2017-10-22 17:49:52 UTC 
UGH, it appears I accidentally copied in text from another error report.  I see no way to edit previous comments :/  Forgive me.  Perhaps I should close this...
Comment 2 Kenneth Graunke 2017-12-01 18:22:11 UTC 
This should be fixed by:

commit ee57b15ec764736e2d5360beaef9fb2045ed0f68
Author: Jason Ekstrand <jason.ekstrand@intel.com>
Date:   Wed Nov 29 16:22:42 2017 -0800

    i965: Disable regular fast-clears (CCS_D) on gen9+
    
    This partially reverts commit 3e57e9494c2279580ad6a83ab8c065d01e7e634e
    which caused a bunch of GPU hangs on several Source titles.  To date, we
    have no clue why these hangs are actually happening.  This undoes the
    final effect of 3e57e9494c227 and gets us back to not hanging.  Tested
    with Team Fortress 2.
