If your name is in the above table, please review your Alpha-1 work
items and either get them closed or push them out to the next milestone.
Remember, Alpha-1 is Thurs Dec 1.
=== Status: Precise Development Kernel ===
We have uploaded the 3.2.0-1.3 Ubuntu kernel which was based on the
upstream v3.2-rc2 kernel. Please install and test on any kit you have.
Feedback is appreciated. We've already discovered breakage with the wl
DKMS package as well as some suspend/resume and shutdown issues on some
Intel Atom kit. If there are any patches which need to land for
Alpha-1, submit them now.
Important Upcoming Dates:
* Thurs Dec 1 - Alpha 1 (~ 1 week)
=== Status: CVE's ===
=== CVE Metrics ===

This week four new CVEs were added to the list. Progress remains slow
and steady, overall we finish the week with about the same number of
outstanding CVEs. One of the new CVEs currently awaits an upstream fix.
=== Status: Stable, Security, and Bugfix Kernel Updates -
Oneiric/Natty/Maverick/Lucid/Hardy ===
Last week saw the verification and testing of the current -proposed
updates. Here is the status for the main kernels, until yesterday
(21/11):
Hardy - 2.6.24-30.96 update was tested (QA), and passed. It's now
released on -security/-updates
Lucid - All reporters verified the bugs fixed by 2.6.32-36.79 update.
QA finished working on it, with no problems found. It's ongoing
Certification testing right now, the update will be released once it
finishes and if no problems are found.
Maverick - 2.6.35-31.62 update passed QA, and is now released to
-security/-updates.
Natty - The current update in progress (2.6.38-13.52) was in
verification for all of the last week. On Monday, we got test results
from the last remaining bug to be verified. The update is now waiting
QA/Certification testing to be released.
Oneiric - 3.0.0-13.22 was released to -security/-updates. A new
update is being prepared this week, since Oneiric is with 1 week of
offset
on the 3 weeks cadence, related to the other updates (and we allow this
on the latest stable kernel). New natty/maverick/lucid/hardy updates
will only be prepared next week.
Besides this, on the derivative and backports packages, we got the
following activity:
linux-fsl-imx51 (2.6.31-612.30) - testing done and update released
linux-ec2 (2.6.32-340.40) - packages were prepared and tested. With no
problems found with QA, it's now officially released.
linux-ti-omap4 (2.6.35-903.27) - QA found some failures, now running QRT
tests (not regressions). Paolo is looking at it.
linux-mvl-dove (2.6.32-420.38) - passed QA, released
linux-lts-backport-maverick (2.6.35-31.62~lucid1) - released from
verification, waiting now for QA
linux-ti-omap4 (2.6.38-1209.17) - Verification and QA done, waiting to
be copied to -security/-updates
linux-lts-backport-natty (2.6.38-13.52~lucid1) - released from
verification, waiting now for QA
linux-ti-omap4 (3.0.0-1206.12) - Released
linux-lts-backport-oneiric (3.0.0-13.22~lucid1) - Waiting for QA to be
released.

(cking)
I've been doing some power management work, is this required to have a
status update in this meeting?
I think it's appropriate to mention it here
probabally it shoudl if it is a series goal
Mainly developing tools and figuring out a test framework, tests and
testing plan:
* vmstat/powertop like power monitoring tool:
git://kernel.ubuntu.com/cking/powerstat.git
https://launchpad.net/~colin-king/+archive/powermanagement
* Got Fluke meter configured and reading data with instrument-lib +
sort out sampling timings, fix a few minor bugs, etc.+
* Wrote tools to parse data logs and graph results (in instrument-lib)
* First cut of automated tests + tools to do multiple runs of tests,
gather
and analyse data (averages, std.dev.)
git://kernel.ubuntu.com/cking/fluke-testing.git
* Survey various power saving options, start writing tests
* Currently looking at Atom N450 power consumption for i386, i386-pae,
amd64
and also general i386 vs amd64 performance differences.
[ACTION] ogasawara add cking power management item to agenda
