Testing on latest drm-intel-nightly from

http://cgit.freedesktop.org/~danvet/drm-intel/

If that doesn't help then please boot with drm.debug=0xe, reproduce the
issue and then attach the complete dmesg. Please make sure everything
starting from boot messages is in there, increase the dmesg buffer with
log_buf_len=4M or so if that isn't the case.
