Not sure if this is relevant, but I had a similar problem: ------------------ Mar 11 16:09:21 bytesize-desktop kernel: [ 1141.077075] [drm:i915_hangcheck_elapsed] *ERROR* stuck on render ring
Mar 11 16:09:21 bytesize-desktop kernel: [ 1141.077095] [drm] capturing error event; look for more information in /sys/kernel/debug/d ri/0/i915_error_state Mar 11 16:09:21 bytesize-desktop kernel: [ 1141.082863] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x6043000 ctx 1) at 0x60431c8 ------------------ The fix for this for me was to change the display drivers to intel-01 drivers ( 01.org ). This bumped the MESA driver from 9.2.1 to 10.0.0. >From what i could guess it seamed to be sandy-bridge related, and apparently got fixed in MESA 9.2.3 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/946899 Title: 8086:2a02 [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
