kernel config
What kernel version has the issue? Also, does kms with with a newer or older kernel version? The affected version is 2.6.35.2, but it seems that I've missed release of .4 so I'll test it with new version and report... Ok, I've tested this kernel versions: 2.6.33 2.6.35.2 2.6.35.4 and all are affected. Is there any other information I should provide to be more helpful? Can you attach a copy of your video bios?

video bios
Just remembered - on 2.6.33 is one difference, after invoking modprobe radeon modeset=1 I got error, but the screen doesn't went blank.
Video bios attached.
Are you loading radeon with the module parameter tv=0? If so, remove that parameter or try this patch: http://lists.freedesktop.org/archives/dri-devel/2010-September/003501.html Patched & tested on 2.6.35.2 -> working. Thanks! :) (this is my first bug on kernel, am I supposed to change status to RESOLVED?) Dave has queued the patch and requested a pull from Linus: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=cf4c12f9a2289e3679722590e1226ae8deb14385 |
