Currently running 3.6.0-02886-gd9a8074 and that one help up OK so far for 28
hours. How long to continue before declaring this kernel good?
Previous bisect kernel 3.6.0-05487-g24d7b40 was found within 24 hours to have
crashed in the bootup textmode screen manner.

The 3.8.10 comment is interesting as the changelog does not mention radeon.
