=== ARM Status  ===
  * Marvell dove
   * Nothing new (they've shipped their LSP 5.3.6)
  * Texas Instruments
   * for ti-omap4, we just fixed a config issue bug 672635
   * PATCH    : PowerSGX patch:
                .Spent a lot of time looking at powerSGX
                .Studied 3 implementation: Android, Meego and rcn-ee
                .The Meego patch was folded in linaro-linux-2.6.35 but got rejected -) not upstreamable
                .To be accepted, the patch would have to be nursed through the iteration process -) this is a full time assignment
                .Going from ubuntu to linaro for kernel maintenance mandate that submitted patches be upstreamable

=== Blueprints: Kernel Configuration Review  ===
Configuration changes are defined and approved.  Work has not yet started on applying these, should hit before natty-alpha-1.

=== Blueprints: Enhancements to the firmware test suite  ===
Changes to fwts (natty development branch):
  * Added more intelligence in backlight issues found in klog
  * add --show-tests-full option
  * add --lp-tags to print out LP tags when scanning klog errors
  * make -p (show progress) default
  * add -q, --quiet option
  * add --dumpfile to load tables from acpidump and fwts --dump output
  * prototyped ACPI method execution for sanity checks and mutex state checks

=== Blueprints: Handling of Deviations from Standard Kernels  ===
Not much to add for the moment.  Working on the announcement scripts. And I guess someone needs to do the documentation at some point...

=== Blueprints: Review of the Stable Maintenance Process  ===
During UDS, discussions were held which resulted in the adoption of a new process for release of stable kernel updates. Details about why this was needed and how it will be implemented have been committed to the Ubuntu wiki here:
https://wiki.ubuntu.com/Kernel/StableReleaseCadence

It looks like the first official cycle may start on Nov 18th, but this is still in discussion.

The question was asked, "how are we progressing on the testing front" to which the answer is: "we aren't". We will be asking that someone responsible for testing attend this meeting to report out on the progress.

Lots of discussion with how to handle reverting patches (or not). The decision was made to take the discussion to #ubuntu-kernel.

=== Blueprints: Ubuntu Kernel Delta Review  ===
Work has started on updating the Ubuntu drivers.  Work centers on updating aufs2 which is a blocker for (performant) live-cds.  Pulled in an experimental version of aufs2 for testing in v2.6.36.  Also pulled this up to v2.6.37-rc1 and did some testing. 
Looking good so far.

=== Blueprints: Kernel Version and Flavours  ===
Pulled the ports meta-packages into the main master branch to simplify ongoing maintenance.

=== Status: Natty  ===
Natty has just moved over to a v2.6.37-rc1 based kernel.  Stability is unexpectedly high.  Work is ongoing to get aufs2 working again so we can have performant live-cds shortly; likely in the next upload.  Blueprints are mostly up to date with initial work 
items and work is just beginning on our deliverables.

Anyone who has not yet added milestones for their work items are likely to find I have assigned them one.  You may well find that means your entire natty workload is now scheduled for natty-alpha-1.  Please review these and split them out as necessary.

  * The Karmic proposed kernel has been moved to updates.

=== Open Discussion or Questions: Raise your hand to be recognized  ===
  * For those who own a blueprint could you add a 'Status:' block to your whiteboards which should be a couple of sentences covering the current progress and any blockers.
  * Discussion about "Subject: Ubuntu ARM and the linaro kernels" (https://lists.ubuntu.com/archives/ubuntu-devel/2010-November/031952.html). Noone knows how or if we will be using linaro provided kernels for natty distro development.
