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)

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.

Open Discussion or Questions? Raise your hand to be recognized

(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:

* 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
