Looks like 1048304 is another dupe of this? 1056511 looks like a very similar backtrace to me as well, even though the driver at the last stage is nouveau rather than cirrus, the rest of it looks the same.
As of todays Quantal update it's stable enough to allow me to login and get a few minutes of useage before failing.
