Oh, we're extremely aware of it. And it's not a new issue, the locking
problem have apparently been around forever, although I'm not sure why
the lockdep splat itself started happening only recently.

They'll make it into 3.9, it's 3.8 that won't have them. The patches
initially caused way *worse* behavior than just a lockdep splat - they
caused actual hard lockups (and that was *after* the initial series of
fixes). That got fixed (hopefully for the last case!) fairly recently,
and I'm not willing to take the scary patch-series that has had
several problem cases.
