Ping? Should I bisect it?

Hi all,

While fuzzing with trinity inside a KVM tools (lkvm) guest running latest -next kernel,
I've stumbled on the following spew:
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.

Cc'ing the fbdev folks
