Can you try this patch for KMS: http://people.freedesktop.org/~agd5f/0001-drm-radeon-kms-update-new-pll-algo.patch or xf86-video-ati git master for UMS? If you want to test UMS, add radeon.modeset=0 to your kernel command line. (In reply to comment #4) > Can you try this patch for KMS: > http://people.freedesktop.org/~agd5f/0001-drm-radeon-kms-update-new-pll-algo.patch I tried to rebuild the Fedora kernel SRPM, with that patch added, but I can't get that patch to apply at all. What kernel version is it against?

What kernel version is it against? > It's against the drm-radeon-testing branch of airlied's drm tree: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=shortlog;h=refs/heads/drm-radeon-testing Also, does the patch on bug 26668 help? It should apply to just about any recent kernel. closing due to lack of feedback. |
