The debug option did not stick for some reason. Also you're hitting a bunch of WARNs in our driver self-checks. Iirc those should be fixed in the latest code. Can you please test with the latest drm-intel-nightly branch from http://cgit.freedesktop.org/~danvet/drm-intel Also can you please attach a dmesg from a working kernel without the i915.modeset=0 option?
