If not please file a bug upstream following http://intellinuxgraphics.org/how_to_report_bug.html and include dmesg when booting with drm.debug=4 and register dumps in the good/bad cases obtained with the intel_reg_dumper tool from http://cgit.freedesktop.org/xorg/app/intel-gpu-tools Cheers, Julien -- To UNSUBSCRIBE, email to debian-x-requ...@lists.debian.org with a subject of "unsubscribe".
