== What was done engineering wise? ==

We uploaded the linux-3.2.0-14.23 and linux-3.2.0-15.24 kernels.  These
uploads contained rebases for upstream v3.2.3, v3.2.4, and v3.2.5.
Additional fixes included support for new broadcom bluetooth devices,
mtip32xx driver updates, vga_switcheroo support for models with nvidia
optimus hybrid graphics, fixes for radeon issues on MacBook Pro 8,2, and
misc regression fixes and config updates.

We also have been tracking the latest upstream releases in our ubuntu-q
git repo [1].  This has most recently been rebased to the latest
upstream v3.3-rc3 kernel.  Again, this repository is strictly for
development and testing purposes only and will be completely unsupported
until we officially release Precise and the Q development cycle begins.

We are above our Beta-1 trend line but should be closing out a few tasks
relatively soon to drop us below the line.  The remaining work items are
not release critical.

== What's about to land that might impact the other teams? ==

We plan to send out an RFC regarding dropping support for the non-smp
powerpc flavor.  We will post to the kernel-team and ubuntu-devel
mailing lists for feedback/discussion before making any changes.
