So finally I have an i915_error_state. I was lucky to have it soft crash this
time. This was obtained through

$ cat /sys/kernel/debug/dri/0/i915_error_state2 > /home/user/i915_error_state
&& gzip /home/user/i915_error_state

kernel: 3.9.3 with Mika's first patch
libva: 1.2.0.pre1
intel-driver (vaapi): 1.1.0.pre1
vaapi version: 0.34.0
intel-xorg-driver: 2.21.7 

P.S.: dmesg output:
