            Bug ID: 96248
           Summary: [SKL] intermittent arb_texture_multisample failures
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

In the past few days I have seen intermittent failures for tests in this
category:

piglit.spec.arb_texture_multisample.texelfetch fs sampler2dmsarray

sample output:
/tmp/build_root/m64/lib/piglit/bin/texelFetch fs sampler2DMSArray 4
98x1x9-98x129x9 -auto -fbo
piglit: debug: Requested an OpenGL 3.1 Forward-Compatible Core Context, and
received a matching 4.2 context

98x1x9
98x2x9
98x3x9
98x4x9
Probe at (500,16)
  Expected: -0.000000 0.333333 0.625000 0.500000
  Observed: 0.098039 0.098039 0.098039 1.000000
....

Also, piglit.spec.khr_texture_compression_astc.array-gl is newly intermittent:
/tmp/build_root/m64/lib/piglit/bin/khr_compressed_astc-array_gl -auto -fbo
Probe at (0,1)
  Expected: 0.156863 0.101961 0.129412 1.000000
  Observed: 0.909804 0.831373 0.784314 1.000000

Because these failures are intermittent, I'll need to do some work to bisect.
