            Bug ID: 106865
           Summary: [GLK] piglit.spec.ext_framebuffer_multisample.accuracy
                    stencil tests fail
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

This seems to only affect HD600 (2x6), and not HD605 (3x6).

Output from one of the failing tests:

/tmp/build_root/m64/lib/piglit/bin/ext_framebuffer_multisample-accuracy 6
depth_draw small depthstencil -auto -fbo
Pixels that should be unlit
  count = 126470
  Perfect output
Pixels that should be totally lit
  count = 131408
  RMS error = 0.141088
The error threshold for unlit and totally lit pixels test is 0.010323
Pixels that should be partially lit
  count = 4266
  RMS error = 0.077997
The error threshold for partially lit pixels is 0.206460
