            Bug ID: 90685
           Summary: [SKL] ChromiumOS WebGL GPU hangs leads to system
                    reboot
           Product: Mesa
           Version: 10.6
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: joon.jung at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

System Environment:
--------------------------
Platform: SKL ChromiumOS
Libdrm: libdrm-2.4.60
Mesa: 10.6.0 - a04b520890c669ce012b4b18165392dcabe0b27b
Kernel: (drm-intel-nightly:
2015y-05m-26d-17h-31m-17s)5267b96e584de7aa76434cc9fefad61169664c2f

Bug detailed description:
-----------------------------
The easiest way is to run a WebGL app on Chromium. A simple 3D box animation
can reproduce it. It looks like it is easier to reproduce when the load is
demanding, for example, running Aquarium 4000 fishes vs. 50 fishes. If left
running, the GPU reset kicks in and recovers but after multiple hangs and
recoveries, eventually the browser reports WebGL failure or the system will
reboot. 

Reproduce steps:
---------------------------- 
Open Chromium browser and run WebGL Aquarium 4000 fishes.
