Dmesg goes : [11010.821533] [drm] stuck on render ring [11010.821537] [drm] GPU crash dump saved to /sys/class/drm/card0/error [11010.821538] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [11010.821539] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [11010.821540] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [11010.821540] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it. [11010.824949] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0xf985000 ctx 1) at 0xf985e00 [11016.849418] [drm] stuck on render ring [11016.849459] [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x10e35000 ctx 1) at 0x10e35e00 [11016.849461] [drm:i915_context_is_banned] *ERROR* context hanging too fast, declaring banned! I can post an error dump for that if it’s of any help. Earlier I got : [ 9058.287646] [drm:intel_dp_start_link_train] *ERROR* too many full retries, give up but I would guess it’s about the display pannel and not related to my hangs and crashes.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
