dmesg showing output from radeon driver after failed rotation
Description of problem:
Using nomodeset due to bug 522260
followed instructions for testing XRandR, tried to rotate the screen. The screen went blank, and X never recovered.
By switching to vt-2, I got an ordinary text mode, and dumped the 'dmesg'. There was nothing interesting in the Xorg log, the dmesg output is attached.
Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages (at least F12Beta, but even better if the very latest versions).
Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you.
If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you.
