attached there is the /debug/dri/0/i915_error_state with 3.5.0-26 kernel

with 3.5.0-26 and 3.5.0-27 kernels after few minutes Xorg get temporary lockups and after about an hour I can only move the mouse pointer and I can kill Xorg with alt+print+backspace, but after that graphics will be corrupted

dmesg with 3.5.0-26:
