Binary Upgrade from 6.1-Stable to 6.2-Release

[Don O'Neil]

I didn't get any response on my original post, so I figured I'd 'summarize'
it better. Bottom line is I'm having SMP problems under 6.1-STABLE-200608
and suspect it's a problem with 6.1 that may have been addressed in 6.2... 

Here are my questions:

I'm concerned about doing a binary upgrade to 6.2 won't fix the problem, and
I've tried using freebsd-update, but it complains about the version not
being compatible. Is there a way to 'force' the ID of the system to be
6.1-RELEASE so that freebsd-update will work? 

If I do a binary upgrade from CD, will it also update the kernel sources so
I can build a new one? Will it complain about it not being compatible like
freebsd-update?

Will doing the 6.1-6.2 binary upgrade as posted by Colin (the author of
freebsd-update) also update the kernel sources? 

Any help/recomendation would be appreciated.
