bisect?
(In reply to comment #3) > bisect? But I find it failed from 20080826, the day GL_EXT_framebuffer_object was supported. Before that it was not supported.
OK, we don't really expect bug reports for always-failing testcases at this point -- our priority is regressions and improving issues that are impacting applications.
This was a bug in the testcase when handling an unsupported framebuffer in a previous test. Yet another reason why you should never build tests that test more than one thing at a time. commit 35122d69307f0b9c88bc143715f616be80ac5cae Author: Eric Anholt <eric@anholt.net> Date: Fri Sep 24 11:28:49 2010 -0700 glean/tfbo: Properly clean up when the driver reports unsupported. Fixes spurious test failures on the intel driver.
It still fails on Pineview now with the same error info as following. libGL: OpenDriver: trying /opt/X11R7/lib/dri/i915_dri.so GL_EXT_framebuffer_object is supported GL_ARB_framebuffer_object is not supported depth = 0, stencil = 1 (0, 0) = [0.000000, 0.000000, 0.000000], is expected to be[1.000000, 0.000000, 0.000000] FAILURE: Render to single texture failed (at tfbo.cpp:850) mode = 2 depth = 1, stencil = 0 (14, 0) = [0.749020, 0.749020, 0.749020], is expected to be[1.000000, 1.000000, 1.000000] FAILURE: Render to depth texture failed (at tfbo.cpp:1155) fbo: FAIL rgba8, db, z24, s8, win+pmap, id 33 6 tests passed, 2 tests failed.

some more info is I tested it with both the glean source contained in piglit test and the glean source from glean.git.sourceforge.net.
