Thank you for the updated dump. It seems that intel_gpu_dump output and i915_error_state is still incompatible, but at least now we know that this is not due to the limited debugging capability of the ubuntu kernel. Maybe this tells the developers something useful.
I have forwarded your bug report upstream to the intel developers at https://bugs.freedesktop.org/show_bug.cgi?id=27614. Please register at bugs.freedesktop.org (if you haven't already) and add yourself to the CC field in the upstream bug report. You will then be able to work directly with upstream to get this bug resolved. If you have any ubuntu-specific questions (e.g. how do I test what they ask me to test?), you can ask here at the downstream report so that the upstream developers are not bothered with that. It is possible that they will ask for the dri_debug info with an updated userspace. You may capture that already by using the xorg-edgers PPA (https://launchpad.net/~xorg-edgers/+archive/ppa) and upload it to the upstream report in order to possibly save one round of communication. ** Bug watch added: freedesktop.org Bugzilla #27614 http://bugs.freedesktop.org/show_bug.cgi?id=27614 ** Also affects: xserver-xorg-video-intel via http://bugs.freedesktop.org/show_bug.cgi?id=27614 Importance: Unknown Status: Unknown ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed => Triaged ** Changed in: xserver-xorg-video-intel (Ubuntu) Importance: Undecided => High ** Tags added: 945gm -- [i945gm] Random X hang https://bugs.launchpad.net/bugs/560376 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
