--- Comment #7 from Kenneth Graunke <kenneth at whitecape.org> ---
Hello, this is most likely fixed in Mesa master by:

commit ee57b15ec764736e2d5360beaef9fb2045ed0f68
Author: Jason Ekstrand <jason.ekstrand at 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.

It should be fixed in Mesa 17.3.0 as well (once that's released).

Please reopen if you still experience hangs.  We've confirmed the fix on
Counter Strike: Global Offensive, Left 4 Dead 2, Team Fortress 2, and Portal 2.
 We didn't explicitly test Counter Strike: Source, but it ought to be fixed as
well.
