Looks real enough but its not a tty/vt layer spew. This is all coming out of the core framebuffer code which doesn't seem to be able to decide what the locking rules at the invocation of fb_notifier_call_chain are.
It might need some console layer tweaking to provide 'register console and I already hold the locks' or similar but that notifier needs some kind of sanity applying as well.
