--- Comment #12 from Emil Velikov emil.l.velikov@gmail.com --- Hello there, a couple of suggestions to make dev's life easier and get things resolved a bit faster. It's unlikely that I will look into the issue itself.
Try to track down the version of - Xorg radeon DDX (xf86-video-ati) - Mesa - Linux Kernel - libdrm/libdrm_radeon
Rebuilding/installing the debug symbols (mesa, kodi, others?) is a good idea ;-)
