I'm running natty, and every since the upgrade to 6.14.0 I've been unable to consistently boot. After some discussion in the forums, I tried repeatedly to boot into recovery mode. In most cases, I got a black screen. One time though, when I was able to successfully increase the brightness, I saw some errors from the radeon module. I took a photo (available at http://i.imgur.com/P0bQ0.jpg), and here's the stack and call trace, as best as I can read it:
There is also some register info dumped at the top of the screen visible in the photo, that I didn't bother to write, as I'd most certainly get something wrong.
