Bug detailed description:
------------------------- 
This new case fails on ILK and SNB with mesa master branch, works well on 10.2 branch.
Following cases also fail:
spec_ARB_shader_texture_lod_execution_tex-miplevel-selection_*ProjGradARB_2DRect
spec_ARB_shader_texture_lod_execution_tex-miplevel-selection_*ProjGradARB_2DRect_ProjVec4

output:
Failure:
  Expected level: 0
  Observed: wrong layer/face/slice or wrong level or wrong offset
  Fetch level: 0, baselevel: 0, maxlevel: 0, minlod: 0, maxlod: 0, bias: 0, mipfilter: no
Summary: 0/1 passed
PIGLIT: {"result": "fail" }

Reproduce steps:
-------------------------
1. xinit
2. bin/tex-miplevel-selection *GradARB 2DRect -fbo -auto
Comment 1 Samuel Iglesias Gonsálvez 2015-06-29 07:45:51 UTC
I tested it on my SNB laptop with mesa master branch. The test passes:

$ bin/tex-miplevel-selection *GradARB 2DRect -fbo -auto
Summary: 1/1 passed
PIGLIT: {"result": "pass" }

$ glxinfo | grep version | grep OpenGL
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.7.0-devel (git-6218c68)
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.0 Mesa 10.7.0-devel (git-6218c68)
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.7.0-devel (git-6218c68)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

Mesa master HEAD: 6218c68bece0cea671f2940a651119a87ab8b24e

Can you still reproduce it on your ILK/SNB machines?
Comment 2 Rhys Kidd 2015-07-12 06:46:40 UTC
Hello Samuel and Lu Hua,

On my ILK laptop the test passes:

$ mesa-release bin/tex-miplevel-selection *GradARB 2DRect -fbo -auto
Summary: 1/1 passed
PIGLIT: {"result": "pass" }

$ mesa-release glxinfo | grep version | grep OpenGL
OpenGL version string: 2.1 Mesa 10.7.0-devel (git-8108de4)
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 10.7.0-devel (git-8108de4)
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

Mesa master HEAD: 8108de4774f2542a8fe65de71b82221821f73434

(mesa-release being my little wrapper script)

Christophe, 
Does this issue still happen on your machines?
Comment 4 Tapani Pälli 2015-09-14 10:00:41 UTC
passes fine on my SNB (tested using Mesa 10.7), seems to pass for others as well so resolving as fixed, feel free to reopen if failure still occurs
