dmesg with GPU_HANG

Software versions:
    4.2.0-1-generic
    OpenGL version string: 3.0 Mesa 11.1.0-devel (git-13a5805)

GPU hardware:
    OpenGL renderer string: Mesa DRI Intel(R) Haswell Desktop 
    00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200
v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

CPU hardware:
    x86_64
    Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

CTS version:
git at 67ae88f31295

command: 
./glcts --deqp-case=ES31-CTS.compute_shader*

Environment:
Mesa built with: --enable-debug
export MESA_GLES_VERSION_OVERRIDE=3.1
export MESA_EXTENSION_OVERRIDE=GL_ARB_compute_shader

----------------------------------------------
When running all the compute shader test of the OpenGL ES 3.1 CTS, execution
stops after 3 or for test with:
"intel_do_flush_locked failed: Input/output error"
dmesg shows:
[drm] GPU HANG: ecode 7:0:0x8fd8ffff, in glcts [23876], reason: Ring hung,
action: reset

This is not reproducible when the tests are run alone.
The issue is not reproducible on Gen8+.
