You mean other than the URL I've supplied at kernel.org and the comments within
tainted.c ?

Probably not, since 13 and 12 are probably a pair in your case.

No.  It is just saying that in the unlikely event you run into a kernel problem 
and
you want to report it you should first check to see if others have the problem 
and/or
try to reproduce it a non-tainted environment.  Like running whatever you 
thought
caused the problem in a QEMU/KVM environment.

I don't think it is very likely that you're going to run into a kernel issue 
that
needs reporting.  I've never had a kernel crash except years ago when 
integrating the
nVidia drivers was a DYI project.
