Created attachment 29868 [details] Error log (KMS is on) Xserver wont start. Latest libdrm, mesa, libgl, ati-dri, xf86-video-ati, xf86-input-evdev installed. After disabling KMS via radeon.modeset=0, X starts.
Please try to get a backtrace with gdb.
Does the patch from bug 24167 help?
I couldn't get the backtrace, I'm sorry. However, I see the patch you've mentioned is applied in the git, I'm compiling xserver again to see is this fixed.
Yes, it's fixed. It appears that this was the same bug as 24167. Thanks. *** This bug has been marked as a duplicate of bug 24167 ***
