Meeting Agenda]]


=== ARM Status  ===
  UUID support: Found a way to support an initrd-less kernel using GPT, 
an hybrid mbr and the ROOTUUID boot parameter, kernel seems to be good 
already.
  lp709245 ("ARM SMP scheduler performance bug"): Still bisecting latest 
P kernel trying to find where the fix for this issue has been embedded 
in the TI BSP - whenever i turn on the the corresponding upstream errata 
(PL310_ERRATA_769419) the kernel hangs on boot, so there must be a 
previous patch clashing in there. Now i'm down to a ~160 commits window.
  P/omap4: Nothing new to report this week.

=== Status: Precise Development Kernel  ===
  Last week we rebased to v3.2.4 and uploaded.  We've recently rebased 
to v3.2.5 and plan to upload shortly.  Note that Beta-1 is on the 
horizon with Beta Freeze approximately 2 weeks away.  We'll be prepping 
our Beta-1 kernel next week.  If there are any patches which need to 
land, submit them now.
  I'd like to also note that we've opened the Q git repo for anyone 
interested (git://kernel.ubuntu.com/ubuntu/ubuntu-q.git).  At this time, 
it is strictly for development/testing purposes only and will not be 
supported until Q officially opens in the archive.
  Important upcoming dates:
   * Thurs Feb 23 - Beta Freeze (~2 weeks)
   * Thurs Mar 01 - Beta 1

=== Status: CVE's  ===
  Currently we have 73 CVEs on our radar, six new CVEs were added this week.
  See the CVE matrix for the current list:


  Overall we have pushed the backlog down by approximatly 2 CVEs this week:


  We have also pushed another CVE back to security for review.  This backlog
  is increasing.
