=== Blueprint: kernel-maverick-bug-handling  ===
Nothing to report. Lots in the wings to be finished soon.

=== Status: Maverick ===
Our Maverick kernel is now rebased to v2.6.35.3 and uploaded as linux-2.6.35-18.24. We've also most notably dropped support for ia64 and sparc per the Tech Board decision.
< >
< >
Maverick Beta is Thurs Sept 2nd, ie ~1week away. Beta Freeze is this Thurs, so I'll be uploading our Beta kernel today. Also, keep in mind that Kernel Freeze is Thurs Sept 16th, ie ~3weeks away. Remember after Kernel Freeze, we transition to our SRU 
policy in order to apply patches to Maverick.
< >
< >
We are above our Beta burn down chart's trend line but below our overall trend line for the cycle. I'll be following up with individuals who have open work items to see if we can close any out.

New security release was done (currently trying to figure out a Hardy
regression in Xen that was caused by that).
<<BR>>
<<BR>>
Uploads to proposed have been re-done for Karmic and Lucid. The uploads
for Lucid-LBM and Lucid-mvl-dove still pending acceptance.
<<BR>>
<<BR>>
One regression fix from Lucid proposed have been moved into the security
update as the severity was high enough.
<<BR>>
<<BR>>
The security update for Lucid-fsl-imx51 included all proposed patches in
order to prevent any further bricking issues with babbage2.5 boards.

=== Incoming Bugs: Bug day report  ===
Today's focus is on bugs with patches. I'll be reviewing them to ensure that there is a patch actually attached. Per Pete, there will then be a review of the bugs to see if the patch has already been included or if it is sufficient to be included. This 
process will be getting further defined once I submit my rough plan to Pete for how to complete the review and inclusion of patches in the future. The next bug day will be next Tuesday. We will be focusing on bugs in the confirmed state and working to move 
them either into incomplete or triaged states. We will continue to have the Team Bug Day to address the Top 50 list as half days on Friday and Monday, as these seem to be working out very well. Reviewers, please take a look at your needs-review lists and 
help us keep the process moving. Please also take ownership of your bugs as you work them so we can get them fixed or otherwise off the list.

=== Triage Status ===
I'm getting pinged by the Ubuntu Studio folks who are concerned about whether the realtime kernels will be available for Maverick. I was in Oxford last week, so I don't have much on this yet. I'd be interested to hear if any of you encountered any triagers 
or their questions over the last week.
realtime or preempt kernels that is

This will be dealt with off-line with the responsible developers.

===  Open Discussion or Questions ===
Leann will be chairing next week's IRC meeting.
