--- Comment #19 from Kenneth Graunke <kenneth at whitecape.org> ---
Some hangs affecting Portal 2 were fixed in:

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.

The original report from January looks a bit different though, so there may be
additional hangs.  Please reopen and attach a new error state if you still
experience issues with Mesa master or 17.3.0 once it's released.  I've been
testing it locally and it appears to be working fine.

Thanks for the reports, and your patience!
