Update on this bug: My first assumption that drm_intel_gem_check_aperture_space() causes this problem is probably wrong. As it turned out, this function fails a lot more often than I see the "failed to submit batch buffer" message in Xorg.0.log - in general without any noticeable impact.
After enabling some more debug output, I am now seeing the error message Execbuffer fails to pin. Estimate: 234897408. Actual: 67125248. Available: 130940928 so I guess that the DRM_IOCTL_I915_GEM_EXECBUFFER2 ioctl in do_exec2() causes the failure. LibreOffice's print dialog can (sometimes) also trigger this bug. -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
