Hi Rodrigo,
I use the latest snapshot (including your patch
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=4df0052a21efd744c4b8cb2409139ded6e45f5c8)
of xf86-video-video to verify this issue in Xubuntu 14.10 beta-1 (because my
built host is xserver-xorg-core v1.15),

commit d08a5f555a0c47ae23c0f9a890b512cb23e74feb

This issue is still able to be reproduced with the same GPU error code in CPU
d-step BDW machine.
