** Attachment added: "Additional output" https://bugs.launchpad.net/bugs/945877/+attachment/2808137/+files/hung_gpu.tar.bz2
** Description changed: I am making an application using OpenGL. Everything works fine, but if I include a call to glPolygonMode(GL_BACK, GL_LINE) in my code, the GPU hangs. I was able to reproduce this three consecutive times (the function call moved around a bit in the code), and see the problem disappear when the function call was removed again. The relevant part of kern.log: [ 189.285257] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung [ 189.285266] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 189.289268] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 19362 at 19361, next 19365) [ 193.243376] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
