Can't locate module char-major-116

[Richard Kimber <rkimber@ntlworld.com>]

I've recently started to receive log messages of the form:- 

modprobe: modprobe: Can't locate module char-major-116

These seem to appear randomly, though everything *seems* to work OK, and
I'm not aware of having made any module-related changes.

I'd be grateful if someone could tell me

(a) where there's a list that would in future show me what char-major-xyz
refers to
(b) what the explanation is likely to be, and whether I need to do
anything about it.

Thanks,
- Richard.
