Lucid Release Status: Bugs

Blueprints: kernel-lucid-bug-handling

Only outstanding item for beta 2 still open: [leannogasawara] apport — sub-system directed reporting [amber]:INPROGRESS all other beta 2 tasks are complete

Blueprints: kerne-lucid-kernel-config-review

PATA and SATA pull out is done and some debian installer fallout sorted out (thanks smb), and the review of the builtin sub-systems complete.

Blueprints: kernel-lucid-kms

I’ve just released a test kernel which addresses the flickering problem with some Intel graphics devices. There are five bugs open against this: http://bit.ly/aiKuuL. Otherwise we are continuing to debug issues as they appear.

Blueprints: kernel-lucid-suspend-resume

Nothing new to report.

Blueprints: kernel-lucid-apparmor-development

Looking at Bug #458299, Bug #529288, Bug #544764, Bug #549428, which all seem to be inter-related or even possibly symptoms of the same bug

• Launchpad bug 458299 in linux “apparmor_parser: page allocation failure. order:5″ [High,Confirmed] https://launchpad.net/bugs/458299
• Launchpad bug 549428 in apparmor “Triggers permanent high i/o load after upgrade” [Undecided,New] https://launchpad.net/bugs/549428
• apparmor “unkillable apparmor_parser” [Undecided,New] https://launchpad.net/bugs/544764
• linux “”Kernel Oops” – unable to handle kernel paging request at ffff880323279bf2 RIP is at aa_dfa_match_len+0xd9/0xf0″ [Low,Incomplete] https://launchpad.net/bugs/529288

Blueprints: kernel-lucid-boot-performance

Looks like the remaining ureadahead work will get postponed to Lucid+1 as the userspace bits are not likely to make Lucid. That likely will close off the blueprint.

Other Release Tasks: Lucid Audio Support

Did a bunch of arsenal work, blasted several hundred alsa-driver bugs with automated comments.

Other Release Tasks: Lucid Better Power Mgt

Pushed a new set of packages out and a CFT (call for testing). No news since.

Other Release Tasks: EC2 Lucid Kernel Status

Did lots of testing for Bug #540378, Bug #527208, haven’t been able to trip either so we are looking good for EC2.

• Launchpad bug 540378 in linux-ec2 “BUG: soft lockup – CPU#1 stuck for 66s! [swapper:0]” [Medium,New] https://launchpad.net/bugs/540378
• Launchpad bug 527208 in linux-ec2 “ec2 instance fails boot, no console output on c1.xlarge” [High,Confirmed] https://launchpad.net/bugs/527208

Status: Lucid

Lucid is at stable 2.6.32.10+drm33.1. We are prepping to the Beta-2 freeze on Thursday, and expect to upload kernels for that early Wednesday. Anything we need in should be up for review _today_.

Security & Bugfix Kernels

Karmic ec2 and mvl-dove have no open bug reports but were rebased to the version of master in proposed. Asked for quick re-test.
