            Bug ID: 104487
           Summary: portal2_linux GPU hang
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

/sys/class/drm/card0/error with mesa 17.3.0

I have Intel(R) Celeron(R) CPU G3950 @ 3.00GHz CPU (Kaby Lake) with integrated
graphics:

00:02.0 VGA compatible controller: Intel Corporation HD Graphics 610 (rev 04)

When I play Portal 2 from Steam on Linux, it often freezes with GPU hang
messages in syslog. I'm using 4.14.6 kernel with Calculate (basically Gentoo)
patchset.

I've tried two versions of mesa: 17.3.0 and git master (commit
0158565924564ec2edca7acd0ccbc33a369ea50d) with libdrm from git as well (commit
831036a6f62005da9fb4a75fe043bd96ce672d27). With both version I got the hangs.

Additionally I tried applying the patch from
https://patchwork.freedesktop.org/series/35325/ (see
https://bugs.freedesktop.org/show_bug.cgi?id=102435#c27), but it did not
resolve the issue.

I'm attaching two hang logs, one with 17.3.0 and the second with git master +
patch.
