I'm quite happy with 3.0 in terms of stability and features, though it's
early days yet.  It's not so good for Debian in terms of timing.  We're
not going to freeze for another 10 months, then the release will likely
be at least 6 months after that.  The earlier a kernel release we pick
with, the more hardware support needs to be backported later.  So,
extrapolating the likely kernel release dates, I think I would prefer to
use something between 3.2 and 3.4.

As for the RT patchset, I haven't seen any announcement that it will
continue to be developed against 3.0 after the release of 3.1.  Of
course, the fact that there *is* a working RT patchset for 3.0 is an
advancement over recent upstream releases.
