Sorry for the long delay in locking at this bug. The SNA issues are unrelated

    drm/i915: Treat crtc->mode.clock == 0 as disabled

Can you please install intel-gpu-tools (git is available at
http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/ ) and grap the output of
intel_reg_dumper for both a working configuration and a broken one.
