AGP module not loaded before graphics module when using plymouth hook
I was getting a "[drm:radeon_agp_init [radeon]] *ERROR* unable to acquire AGP: -19" error at boot, after "starting version 219" and before plymouth took over the screen when following the instructions. E.g. hooks="base udev plymouth ...", despite having modules="via_agp radeon ...".
Not sure if it's a problem with the current plymouth hook but I removed it from mkinitcpio.conf, rebuilt initramfs and the error goes away -and- I still have plymouth on boot. --Kit (talk) 21:13, 21 May 2015 (UTC)
