  If your name is in the above table, please review your Alpha-2 work 
items.  Note that Alpha-2 is Thurs Feb 2.

=== Blueprint: hardware-p-kernel-power-management  ===
  Power Management:
   * Write up results from wake events analysis and file lots of bugs
     http://zinc.canonical.com/~cking/power-benchmarking/events/
   * Write cpustat: git://kernel.ubuntu.com/cking/cpustat.git
     Test CPU utilization, results:
     http://zinc.canonical.com/~cking/power-benchmarking/cpu/
   * Investigate MSR_IA32_ENERGY_PERF_BIAS on sandybridge, no +ve results
     need to rig up Ivybridge desktop to sanity check this.
   * LP#911325 - new pm-utils scripts to save power
   * Collect power measurements on Hardy, Lucid, Maverick, Natty, 
Oneiric, Precise

=== Status: Precise Development Kernel  ===
  Over the holiday break we rebased to v3.2-rc7 and uploaded.  Aside 
from that not much else has been done.
  Important Upcoming Dates:
   * Thurs Feb 2 - Alpha 2 (~4 weeks)

=== Status: CVE's  ===
  === CVE Metrics ===

  We have had two new CVEs added to the matrix since the last report. 
Two of those without upstream fixes have had those identified and have 
been triaged to specific releases.


=== Status: Stable, Security, and Bugfix Kernel Updates - 
Oneiric/Natty/Maverick/Lucid/Hardy  ===

  Here is the status for the main kernels, until today (19/12):

   * Hardy - 2.6.24-30.98
    * New kernel, now in verification. Contains commits for 5 CVEs.

   * Lucid - 2.6.32-38.82
    * New kernel, waiting to be copied to -proposed. Contains a stable 
upstream
      release as well as some CVEs. This also turns CONFIG_NET_NS back on.

   * Maverick - 2.6.35-32.64
    * New kernel, waiting to be copied to -proposed. Contains a rare, stable
      upstream release as well as some CVEs.

   * Natty - 2.6.38-13.53
    * New kernel, now being built.

   * Oneiric - 3.0.0-15.25
    * New kernel, now in verification. A regression was identified in the
      previous -proposed kernel (bug 904569). The offending commit was 
reverted
  * [[https://launchpad.net/bugs/904569|Launchpad bug 904569 in linux 
(Ubuntu Oneiric) "Linux 3.0.0-15 causes laptops to fail to resume from 
suspend (Dell XPS 1645, Sony Vaio VPCF1390)" [Undecided,In progress] ]]
