=== Blueprint: hardware-p-kernel-power-management  ===
  Power Management:
   * Bluetooth power consumption in suspend

   * Background colour with DPMS off
     http://zinc.canonical.com/~cking/power-benchmarking/background-dpms
   * Call for testing: latest RC6 fixes, 
https://wiki.ubuntu.com/Kernel/PowerManagementRC6
     Please *re-test* if you haven't already done so. Thanks to Leann 
Ogasawara
     for organising this.

=== Status: Precise Development Kernel  ===
  The archive remains frozen for the upcoming Beta-1 release on Thursday.
  We received a Beta Freeze exception last week to upload a fix for the
  RC6 patch we applied.  This has received positive testing feedback and
  it looks promising that we will be able to ship with RC6 enabled by
  default.
  We have been queueing patches for the first post Beta-1 upload.  This
  will include a rebase to the latest v3.2.8 upstream stable release.  We
  will need to coordinate our upload with the planned gcc-4.6 upload.
  Important upcoming dates:
   * Thurs Mar 01 - Beta 1 (~2 days)

=== Status: CVE's  ===
  Currently we have 74 CVEs on our radar, two new CVEs were added this week.
  See the CVE matrix for the current list:
  http://people.canonical.com/~kernel/cve/pkg/ALL-linux.html

  Overall the backlog is broadly unchanged this week, we have closed one
  of the new CVEs and the other is already fixed for a number of releases:
