I just started getting X failures that say:
[ 739.208] (EE) RADEON(0): [drm] failed to set drm interface version.
I'm not sure what triggered it.
dmesg says:

-13 means -EACCES.
We'd need to see dmesg from the beginning to be sure, but it looks like something (maybe plymouth or whatever boot splash you're using?) is keeping the DRM device open, so Xorg doesn't become DRM master.
