Hi Chris et al, On my Sandy Bridge GPU (8086:0126 rev 09) laptop, I often see hangs that are correctly recovered and sometimes ones which aren't (causing X lockup or kernel hard lock), hurting usability.
I'm able to reproduce GPU hangs often with the composite tests in rendercheck (may need to restart a few times): $ ./rendercheck -t composite,cacomposite Begin composite mask test on a8 <command hang, maybe GPU hang too> I'm on the internal LVDS panel (1600x900), and can produce this with 2.6.39-rc7 and Xorg 1.10.1 (Ubuntu 11.04 + gnome 3). Kernel logs are captured booting with 'drm.debug=0x04' [1], and i915 error state is at http://quora.org/2011/i915_error_state.txt.bz2 . Any joy in reproducing it there? Thanks, Daniel --- [1] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
