Hello to all. Sorry if these aren't right place, please point me to the right direction if you can :)
When trying new 2.6.35-rc4, our kernel team (ArchLinuxPPC) has tried to setup KMS acceleration for radeon based machine. We have removed radeonfb, and all others framebuffer driver, and added fbcon and KMS enabled by default for radeon driver. With a clean start, the screen freeze, when the control pass from yaboot to kernel. If we start with video=fbcon (or video=radeondrmfb), we could reach the loading modules point, but after the loading of radeon, the screen goes black, without any log information. Loading kernel with video=fbcon radeon.modeset=0 allow us to reach the end of init stage, and we could load X.org. In this case, acceleration is disabled. If we log out and do the following command: modprobe -r radeon drm modprobe drm debug=1 modprobe radeon modeset=1 The screen goes black, but at next boot we have found the logs. Any hint?
