I get the same error as you, and have reported this earlier. I also included text core dump as attachment in the message. How did you manage to paste the dmesg text here? Is there are way to attach dmesg on the generated core dump? After my laptop panicked, the only thing I could do was take a shot of the dmesg with a camera.
