--- Comment #4 from Imre Deak <imre.deak at gmail.com> ---
Could you try the latest nightly kernel? There's been quite a lot of BYT
related fixes since -rc4:

git://people.freedesktop.org/~danvet/drm [drm-intel-nightly]

If that doesn't work could you provide a register dump both with and without
i915.modeset=0, before any client (plymouthd) would access the driver?  The
required tool is at:

git://anongit.freedesktop.org/xorg/app/intel-gpu-tools

and (with debugfs mounted) you need to run as root:

# tools/quick_dump/quick_dump.py -a

Thanks.
