--- Comment #63 from udo udovdh@xs4all.nl --- 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.
