            Bug ID: 100932
           Summary: [regression] GPU hangs in Sacha Willems'
                    Multithreading Vulkan demo
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: eero.t.tamminen at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

Last time Sacha Willems' Multithreading Vulkan demo worked fine was with:
-----------------------------
b295a52836 at 2017-04-27 16:52:25 UTC
clover: Fix build since clang r301442
-----------------------------

Day later, at:
-----------------------------
85ca563b58 at 2017-04-28 15:54:45 UTC
anv: Drop 'x11' prefix from non-X11 WSI funcs
-----------------------------

And after that, it seems to be GPU hanging on all GEN8+ SOC platforms: BSW,
BXT, GLK...

On BYT there have started to be GPU hangs in ComputeNBoby Vulkan demo (not in
Multithreading), but I don't know whether it could be related, there's a large
gap in our data for BYT around that time.
