radeon regression 3.11.0-rc2+

Hello I just upgraded Kernel from 3.10.0-rc6+ to 3.11.0-rc2+ and ran serious problems. That Kernel is current Linux Media master, which contains some upcoming media stuff that should not still has any effect, but lets mention for sure.

Display started freezing and gone black, I think two times. Next freeze led to effect screen was full of very colourful boxes. It recognized mouse moves but text was unable to read so I was forced to hard boot to old Kernel. Attached log contains stuff I found from the debug log.

OS Fedora 17 01:05.0 VGA compatible controller: ATI Technologies Inc 760G [Radeon 3000]
