I cannot reproduce this failure on my mobile SNB (8086:0126 (rev 09)). If you are still able to reproduce this either at current tip of 8.0 (0e08205) or at the bisected commit, can you provide the '-v 4' output from one failing visual? Xun is out today. Ouping, can you check it today? (In reply to comment #2) > Xun is out today. > Ouping, can you check it today? Oops, just realized Ouping is also out today. Let's wait for Xun tomorrow. This failure is unstable on mobile SNB. It is easy to reproduce this failure on sugarbay at current tip of 8.0(65b50085).
The bisect commit seems not correct because autobisect find another bad commit.

Are you not building with --enable-texture-float? > GLSL Version - '1.30' We are not building with '--enable-texture-float' on Mesa 8.0 branch.
I build mesa 8.0 with '--enable-texture-float' and retest the case.

I am unable to reproduce this failure on current Mesa master or Mesa 8.0.4 release on Sandybridge mobile. Xun, can you confirm? It still fails on current Mesa master or Mesa 8.0.4 release on Sandybridge(include mobile), Ironlake and Ivybridge. reproduces on my old oglconform snapshot on ivb, at least. Couldn't reproduce. Test passes with mesa master(1e85713) on mobile SNB. I am able to reproduce this failure on current Mesa master or Mesa 9.1 on Ironlake, Sandybridge, Ivybridge and Haswell. tested on SNB desktop with oglconform 42.01.580 and mesa master [3.0 Mesa 10.1.0-devel (git-8d1400f], all 12 tests are passing. all tests passing also on IVB ultrabook, therefore resolving this Verified it on latest mesa master and 10.2 branch. |
