Screenshot of rendering error
Can you please attach your Xorg.0.log? (Primarily to confirm the versions.) And of course, X aborting deserves attaching the gdm.log (or xdm.log, whatever). Created attachment 65270 [details]

i915_error_state dump
At the point the rendering garbage appears, there is no error in X and anything else. The abort of X comes from gnome-shell's crash because of GPU hang. So I don't think it's interesting to see, it's too away from the culprit :) Currently the machine has an older version of X/libdrm/Mesa stack for SLED11-SP2 testing. If you'd like to check inevitably the versions in Xorg.log, I can reinstall the machine freshly from openSUSE-12.2-RC2. Let me know. BTW, one more thing I forgot to mention: the fbdev works fine. When I start X with fbdev, there is no rendering problem nor GPU hang. The problem happens only via DRM. That error state is from a broken UXA (using 86 PS threads on IVB GT1). Can you please confirm you are testing with the latest release of xf86-video-intel-2.20.3 and the current mesa-8.0 branch (the GT1 bugfix has not yet landed in a stable release). OK, I'll reinstall the machine and give logs back. Indeed the recent commit in Mesa seems fixing the GPU hang with 3D. The rendering issue looks like a problem in the original openSUSE-12.2 xf86-video-intel package, which is version 2.20.0, so also missing GT1 fix. I'll play a bit more whether it's really stabilized. Confirmed that everything works now with the latest Mesa 8.0 git branch. Thanks for the hint! |
