Bruno, Please help me understand, how does this scenario occur? I'm interpreting what you've written above to mean that fbcon is accessing the framebuffer before you've called defio_init()? Is that correct? The typical defio use sequence is: defio_init(), register_framebuffer() and the typical remove sequence is in the reverse order unregister_framebuffer(), defio_cleanup(). So, I don't see how fbcon is accessing the framebuffer either before register_framebuffer() completes (at which point defio init is already done) or after unregister_framebuffer() completes.
