--- Comment #1 from Ander Conselvan de Oliveira <conselvan2 at gmail.com> ---
Please boot your kernel with drm.debug=0x1e in its command line, reproduce the
bug again and then attach the output of dmesg here.

Also, could you check if the issue exists with the drm-intel-nightly branch
from http://cgit.freedesktop.org/drm-intel?
