I've encountered an issue with the DRM driver on the 3.8.13 kernel that others might have had before and I'm looking to track down. I wanted to get the info out on the list as I try to track this down. I think I'm seeing something similar on the 3.12 kernel as well.
https://gist.github.com/jadonk/7665464 In particular, I get the below error, but there are errors earlier in the log as well.
