sourceArea->name, sourceID);

That's not really such a good idea IMO.
First of all, the comment was not updated when the semantics of this check changed.
Then, it may make sense to only dprintf() for userland areas for now (if only because this would break compatibility otherwise), but for kernel areas, I would insist on keeping the panic.
