           Summary: [SUMO][TURKS] Launching War Thunder make GPU stuck,
                    and then system is hard lockup
           Product: Mesa
           Version: 17.3
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org

Hello!

Launching War Thunder make GPU stuck, and then system is hard lockup. This
issue is starting to happen after upgrade from Mesa 17.2.2 with libdrm 2.4.83
to 17.3.0rc4 with libdrm 2.4.85 (from Padoka Stable PPA
https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa ) on Kubuntu
17.10 x86_64. As soon as I rollback to Mesa 17.2.2 and libdrm 2.4.83, GPU
lockup is no longer reproducible, but then there is another issue: bug 100387

Issue is reproducible on both of iGPU and dGPU. Please look into attached log.

Hardware: 
Acer Aspire 7560G, AMD A8-3500M
AMD Radeon HD 6620G iGPU, AMD Radeon HD 6650M dGPU.

Software:
Kubuntu 17.10 x86_64, Linux 4.14.1.
radeon DDX and modesetting DDX was tested, no difference.

Yes I can confirm this on Radeon HD 4350. Even the game itself shows a dialog
about hangup, but then the GPU is hung for a while. I think it restarts
eventually and takes down the X server (and KDE session). But then I can
normally login to KDE again.

After turning off shader optimization with R600_DEBUG=nosb 
War Thunder works and doesn't crash.

There was quite of an improvement in sb, in the last couple of mesa releases
(even though bug 105371 would make me hesitant to say now it's 100% fixed)

Does war thunder work then in 18.3?

Based on
https://forum.warthunder.com/index.php?/topic/422637-game-crashes-before-going-into-hangar/&do=findComment&comment=8058647,
I seems like this bug hasn't been fixed(although the user in question didn't
supply their version of Mesa).

A user in the linked source supplied the following system specifications:
Dell Precision M4600
Ubuntu 18.04.2
i7 2720QM CPU @ 2.20GHz x 8
32GB RAM
GPU AMD Turks (FirePro M5950)

The default version of Mesa in Ubuntu 18.04 is 18.0.0rc5.
