=== Status: General Oneiric  ===
Per bug 837332, we've spun a last minute upload of the kernel this morning to ensure CONFIG_EFI_VARS=y.  We've also added this config to our enforcer now.  I was a bit too strict with the enforcer check which has resulted in FTBFS for powerpc and arm.  The 
release team has chosen to ignore those for now and we'll get it resolved on the first upload after Beta-1.
  * [[https://launchpad.net/bugs/837332|Launchpad bug 837332 in linux (Ubuntu) "missing efi-modules udeb" [High,Fix released] ]]
Additionally, upstream stable v3.0.4 has been released so we'll be rebasing shortly.  We'll upload the v3.0.4 rebase as well as any queued patches on master-next this Friday after Beta-1 releases.  I would also like to remind everyone that Kernel Freeze is 
fast approaching, ie Thurs Sept 15.  After that, 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 1 - Beta 1 (2 days)
  * Sept 15 - Kernel Freeze (~2 weeks)
  * Sept 22 - Beta 2 (~3 weeks)
  * Oct 13 - Final Release (~6 weeks)
I'd also like to note that the P-series git repo was recently rebased it to v3.1-rc4.  It's available at git://kernel.ubuntu.com/ubuntu/ubuntu-p.git master-next .

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

We have a few new CVEs this week, a result of the security team cleaning house.

=== Status: Stable Kernel Team ===
We've finished the verification phase for Lucid and Maverick, which was
delayed due to time required to find regressions. Two fixes have been reverted
from those kernels due to a failure to have them verified.
< >
< >
In addition, another regression was reported in Lucid, and the patch was reverted.
< >
< >
Both Lucid and Maverick have been respun and uploaded, and the builds should
be completed tomorrow, and they will be ready to enter testing phase.
< >
< >
We have gone ahead and prepared the nect Natty kernel without waiting for the next
cycle to start for the other kernels, so that we don't pile up more stable upstream
patches than we must. This effectively decouples Natty from the kernel cadence for
the other kernels
