Description of problem: After upgrading to the latest F9 kernel build 2.6.25.7-65.fc9, Xorg stops working on an ATI Radeon X800. During start-up, the monitor goes to power saving mode due to a missing video signal. The system needs a hard reset to reboot. Version-Release number of selected component (if applicable): kernel-2.6.25.7-65.fc9.x86_64 How reproducible: Always. Steps to Reproduce: 1. Boot F9 with kernel 2.6.25.7-65.fc9. Actual results: Monitor goes to power saving mode. System is locked. Expected results: Boot-up procedure completes successfully. Additional info: - The latest entry in the changelog reads * Fri Jun 20 2008 Dave Airlie <airlied> 2.6.25.7-65 - update radeon patches to newer upstream which is obviously the cause of the issue. - Reverting to kernel-2.6.25.7-64.fc9 restores normal operation.
Created attachment 309843 [details] Xorg.0.log in case of failed system boot procedure.
Issue also occurs for kernel-2.6.25.7-65.fc9.i686 after reverting to the x86 version of Fedora 9.
