The problem we're talking about was a direct result of this PR:

http://www.freebsd.org/cgi/query-pr.cgi?pr=166656

The commit (MFC) was done to stable/8 and stable/9 in this revision and
at this date/time:

stable/9 commit: r247335 -- 2013/02/26
stable/8 commit: r247336 -- 2013/02/26

You can see the commit log/messages in the PR.

Now let's talk about versions:

FreeBSD 9.0-RELEASE came out 2012/01/12:

FreeBSD 9.1-RELEASE came out 2012/12/30:

http://lists.freebsd.org/pipermail/freebsd-announce/2012-December/001448.html

So when you say "the issue" for you "began at FreeBSD 9.0", you need to
be more specific (uname -a output would be a good start), because
otherwise to me it sounds like you're experiencing a *completely*
different problem.

> Much appreciated, shouldn't this be at wiki? 

What wiki?  How would people know to read it?  Using a web search engine
like Google?  That would return this mailing list thread, as well as
the ones I've referenced.

There is enough old/outdated/completely and absolutely WRONG crap on the
FreeBSD Wiki as is.  The Wiki is not the "official source/list of
problems" (there is no official source/list -- the mailing lists are,
for a decade, have been as good as it gets).
