=== Bugs with Patches Attached:110 (not counting Fix Committed)(down 2)
Breakdown by status:

=== Blueprints: kernel-lucid-bug-handling (JFo) ===
No update, all items are still in progress.

=== Blueprints: kernel-lucid-review-of-ubuntu-delta (apw) ===
Lenovo driver confirmed no longer required and dropped.  This blueprint is essentially complete and this item wll be removed from the meeting agenda.

=== Blueprints: kerne-lucid-kernel-config-review (apw) ===
It seems we require SECCOMP enabled for Lucid, preliminary patches for ARM are under testing.

=== Blueprints: kernel-lucid-kms (sconklin / apw) ===
The v2.6.33 DRM backport is looking very much the better starting point in most testing.  There are still issues to resolve but they are much much less severe.  The final go/no-go decision is expected in the next couple of days with the change occuring 
this week.
We have been attempting to test the main Lucid kernel and also the Lucid kernel with the .33 drm backport, but have encountered problems with suspend/resume that appear to be related to the Iron Lake processor but not the drm drivers. We are continuing to 
try to sort out these problems.

=== Blueprints: kernel-lucid-suspend-resume (manjo) ===
Nothing new to report.

=== Blueprints: kernel-lucid-apparmor-development (jjohansen) ===
Another submission going out today, wanted to sleep on d_path and d_namespace changes.  Also pam_apparmor will be finished up today.  Upstream is generally receptive to the new patches, the d_path stuff is getting the most conversation.

=== Blueprints: kernel-lucid-boot-performance (apw, csurbhi) ===
We remain around the 1.6s to rootfs mark.  There is some instability in the figure which looks to be a race during boot, needs further investigation.  Patches for incremental readahead detection are now in testing.

=== Other Release Tasks: Lucid Audio Support (bjf) ===
Nothing new to report.

=== Other Release Tasks: Lucid Better Power Mgt (amitk) ===
Nothing new to report.

=== Other Release Tasks: EC2 Lucid Kernel Status (jjohansen) ===
Nothing new to report.

=== Status: Lucid (apw) ===
Lucid is at stable v2.6.32.9.  We have taken a few small update icluding a wacom driver update.  As mentioned above we are still looking to update graphics with that likely to be the outcome.  Progress has been pretty solid the last week, but new tasks and 
bugs pulling us back from the trend-line.  There is a fair bit to do before kernel freeze but the new bits should be in in time.  We will have to do some fixing after that.  We have closed off one of the slipped items, the rest remain and need pushing. If 
you have an at-risk item, i would like to know when its likely to be done.

=== Security & bugfix kernels - Karmic/Jaunty/Intrepid/Hardy/Others (smb) ===

  For Karmic: the following bugs are unverified:
   * bug 504273, bug 494045, bug 494461 and bug 510722 (intel graphics)
   * bug 458503 and bug 458503 (hotkeys)
   * bug 506180 (ath5k regression by stable)
  For now there were some doubts on bug 452558 as of whether 96MB of memory stolen is a high ratio of overall memory on ARM. Probably someone with knowledge has to say there is still enough left.
