Status: Quantal Development Kernel

We’ve recently uploaded the 3.5.0-13.13 Quantal kernel to the release
pocket. This upload most notably provides a rebase to the v3.5.3
upstream stable release. This was also uploaded to the q-lts-backport
[1] PPA to help facilitate testing of the 12.10 kernel in 12.04. We
welcome anyone to please install, test, and let us know your feedback.
[1] https://launchpad.net/~ubuntu-x-swat/+archive/q-lts-backport
Note that we are 2 days away from Beta-1 Freeze and ~1 week away from
Beta-1 intself. I do not foresee any further uploads before Thursday,
ie. Beta-1 Freeze. If there are any critical fixes which need to land,
we need to know now. Any uploades after Beta-1 Freeze will require
approval from the release team.
Important upcoming dates:

  • Thurs Aug 30 – Beta 1 Freeze (2 days)
  • Thurs Sept 6 – Beta 1 (~1 week)


Status: CVE’s

== 2012-08-28 (weekly) ==
Currently we have 88 CVEs on our radar, with two CVEs added and two CVEs retired this week.
See the CVE matrix for the current list:

Overall the backlog has decreased slightly this week:

ARM Status

Q/omap4: a new Q/omap4 3.5 kernel was uploaded yesterday (3.5.0-208.14) and a new one that includes all the patches that went into tilt-3.4[1] after i
started my porting is being worked on.
Hopefully this new one (3.5.0-209.15 [2]) will be the last one before beta1,
and it should fix the hangs rsalveti experiences with pvr-omap4.
Source code is available here:

The entire patchset is available at http://people.canonical.com/~ppisati/ti-omap4-tilt-34-on-35/tilt-3.4/
There’s a tracking bug following kernel consolidation here: http://bugs.launchpad.net/bugs/1035289
Right now i’m cleaning up the boot process(WARN_ON()&c), rebasing on latest Q/master, importing latest Q/omap4 config changes, etcetc
i’ll start tackling the analog audio in the next few days.
