I have heard of mei issues recently, but no real "this is a problem"
type thing.  There are some patches queued up for 3.12 in that area, if
they are needed earlier, that would be great for me, as a subsystem
maintainer, to know.

The openSUSE Tumbleweed disto also pushes out these stable kernels.  But
there's only an "estimated" 8-10 thousand users of that openSUSE
"flavor", while smaller than what Fedora has, it's better than nothing.

I would love that report, one of the things I keep asking for is for
people to send the patches that distros have that are not in stable to
me, as those obviously are things that are needed for a valid reason
that everyone should be able to benifit from.

If they aren't "allowed" by the current rules, I'd be interested to know
why, unless it's the "add a new feature" type thing, which makes sense
why I couldn't take them.

I care :)
