https://bugzilla.kernel.org/show_bug.cgi?id=30832 Summary: Radeon S-Video Out has become black and white. Works fine in 2.6.37 Product: Drivers Version: 2.5 Kernel Version: 2.6.38.6 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx ReportedBy: arbitrabbit@xxxxxxxxxx Regression: Yes The S-Video out of Radeon driver has become black and white in kernel 2.6.38.The regression happened around 2.6.37.2 as the driver worked fine in 2.6.37. I have a Radeon HD4850 card. Here is the difference in the dmesg output from the two kernels. I can hardly notice any difference, other than timestamps. In kernel 2.6.38, initialization happens very quickly - maybe a timing issue? Other than the kernels, everything else is same. 2.6.38-6-generic [ 9.422549] [drm] Initialized drm 1.1.0 20060810 [ 10.094022] [drm] radeon defaulting to kernel modesetting.
