Bug detailed description:
-------------------------
On IvyBridge there are about 600 ogles2conformance cases will has X hang or X hang with Missing IRQ errors, its pass rate is 560/1198. It works well on SandyBridge, its passrate is 1191/1198. And I tested this is under gnome desktop with compiz disabled. (when enable compiz will make GPU hang, as bug 38362)
Some of the affected cases are:
Ogles2conform/GL_acos_acos_float_frag_xvary.test    Ogles2conform/GL_acos_acos_vec2_frag_xvary.test
Ogles2conform/GL_biConstants_gl_MaxCombinedTextureImageUnits_vert.test    Ogles2conform/GL_biConstants_gl_MaxDrawBuffers_frag.test    Ogles2conform/GL_biConstants_gl_MaxDrawBuffers_vert.test    Ogles2conform/GL_biConstants_gl_MaxFragmentUniformVectors_frag.test
...

Reproduce steps:
-------------------------
1.disable compiz(cd /usr/bin; mv compiz compiz.bak )
2.xinit&
3. gnome-session
4. ./GTF -width=64 -height=64 -run=GL/acos/acos_float_frag_xvary.test
Comment 1 Kenneth Graunke 2011-06-29 10:41:53 UTC 
Strange; this was working fine for me last I checked.  I'll reconfirm tomorrow.  In the meantime, reassigning.
Comment 2 meng 2011-06-30 03:27:18 UTC 
Test with on IVB,
disable compiz:some cases "Missing IRQ",but no "X hang".
enable  compiz:some cases "Missing IRQ" and "X hang".

some cases "X hang"(follow cases reproduce X hang:1/5):
GL_atan_atan_float_frag_xvaryyvary.test
GL_biConstants_gl_MaxFragmentUniformVectors_frag.test

Still haven't seen this, but I haven't tried with Compiz running.  I'll have to try that soon...
