=== Status: General Oneiric  ===
We uploaded the 3.0.0-12.19 Ubuntu kernel last friday.  We are nearing Final Freeze for Oneiric this Thurs, Sept 29.  Only high/critical issues which are deemed necessary for the release will warrant an upload at this time.  Because we are in Kernel 
Freeze, all patches are subject to our SRU policy in order to be applied.
Some important upcoming dates to keep in mind are as follows:
  * Sept 29 - Final Freeze (2 days)
  *  Oct  6 - Release Candidate (~1 week)
  *  Oct 13 - Final Release (~2 weeks)
I would also like to note that the P-series git repo has been rebased to v3.1-rc7 and is available on the master-next branch at git://kernel.ubuntu.com/ubuntu/ubuntu-p.git .

=== Status: CVE's  ===
Currently open CVEs for each supported branch:

One additional CVE was added this week and all CVEs with fixes are now closed out.  We have referred two of the Hardy CVEs which have very large patch stacks back to the security team for review.

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

  An i915 graphics regression was discovered in Natty which was released in -updates.
  The offending patch has been identified and will be reverted in the next Natty
  kernel. Work is under way with upstream to come up with a new fix to add external
  monitor plug support without regressions. The bugs open for this regression are:
  * [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/838181|External monitor connected trough . . .]]
  * [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/814325|fuzzy and corrupted display after dpms cycles]]

  SRU kernel status:
  * [[http://people.canonical.com/~kernel/reports/kernel-sru-workflow.html|Kernel SRU Workflow Status]]
  * [[http://people.canonical.com/~kernel/reports/sru-report.html|Detailed Information Here]]

  Kernel status for each series is as follows:

===== Hardy =====
  * [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/853945|Hardy Tracking Bug]]
  * Currently undergoing regression testing

===== Lucid =====
  * [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/849228|Lucid Tracking Bug]]
  * Awaiting publishing to -updates and -security

===== Maverick =====
  * [[https://bugs.launchpad.net/ubuntu/+source/linux/+bug/854092|Maverick Tracking Bug]]
  * In testing Phase. Undergoing regression testing, needs Certification testing

===== Natty =====
  * In preparation, should be in Verification phase by the end of this week

  Current Kernel versions are available here: http://people.canonical.com/~kernel/reports/versions.html
