Open action: manjo to send a firewire patch with test info

tgardner uploaded the latest package of module-init-tools which contains the switch. pgraner and I have tested the new stack, and I have also tested this in Lucid and found to perform better than the old stack. pgraner did tests with dvgrab, kino, and files transfer across HDDs, and all checked out ok. Thanks to pgraner for all the testing. Jfo will issue a call for testing soon. Since this item is all done we can have this item removed from the meeting agenda.

Open action: JFo to put out a CFT on new firewire stack

Will send out today.

Breakdown of bugs with patches


Blueprint: kernel-maverick-apparmor

Fixed Bug #581525 both kernel and user space and am about to push out test kernels for reporters to verify. Have a patch for Bug #599450 that needs to be tested. Bug #602261 has been reported as a potential AA issue, looking into it. We have some compiler patches that reduce memory usage that will get synced with alpha3. Looking into duplicating and the bug and seeing if it is AA.

  • [[|Launchpad bug 581525 in apparmor (Ubuntu) “Lucid: system becomes unstable randomly, seems related with apparmor” [Undecided,New] ]]
  • [[|Launchpad bug 599450 in linux (Ubuntu Maverick) “[apparmor] getattr handled incorrectly in 2.6.35-6.7” [High,New] ]]
  • [[|Launchpad bug 602261 in linux (Ubuntu) “Thrashing and OOM during upgrade from 10.04 to Maverick” [Undecided,Incomplete] ]]
    (apw) Notes that that bug occurs when running lucid (pre-update kernel). (jjohansen) Agrees, though it is likely userspace component since the compiler consumes 80-100MB.

Blueprint: kernel-maverick-firewire-stack

See open action item above. This blueprint topic will be removed from future agendas.

Blueprint: kernel-maverick-misc

Some work on cleaning up lintian errors is ongoing. Nothing else to report.

Blueprint: kernel-maverick-new-kernel-on-lts

Nothing new this week.

Blueprint: kernel-maverick-pv-ops-ec2-kernel

Have update Xen patchset, that I will start testing today. Amazon have opened their pv-grub based loader for general use so I will be revisiting the pv-ops based kernel.

Blueprint: kernel-maverick-ubuntu-delta-review

Since we won’t be using union-mounts in Maverick, we’re planning an aufs update for Alpha3.

Blueprint: kernel-maverick-union-mounts

Based on the lack of feedback we will assume staying with aufs2 for Maverick. Preparations to update aufs2 are in progress. This blueprint topic will be removed from future agendas.

Blueprint: kernel-maverick-config-review

We have 2 misc bugs to close for Alpha3. Both are already assigned to a kernel dev and In Progress.

Blueprint: kernel-maverick-bug-handling

Nothing new this week.

Blueprint: kernel-maverick-upstart

The ureadahead patches remain untested. Will bring this up with foundations.

Blueprint: kernel-maverick-bios-test-automation

Changes to Firmware Test Suite this week:

  • Additional Tests:

    • thermal_trip: Check Thermal Zone trip mechanism.
    • cpufreq: Check P-states across all CPUs.
    • bios_info: Gather BIOS version information.
    • microcode: Check if latest microcode is loaded.
    • maxfreq: Check CPU max freq against BIOS setting.
  • Other changes:

    • hibernate: Fix S4 detection bug, check for hibernation phases.
    • lid: Detect GPE activity on lid events.
    • WMI: Only dump driver writing advice text out once.
    • ACPI tables: Extract ACPI tables without the need for acpidump.
  • Misc:

    • Wrote Python version of acpidump for inclusion into apport
    • Maverick PPA builds for new code.

Status: Maverick

linux-2.6.35-6.9 was uploaded immediately upon Alpha2’s release. I expect the upstream 2.6.35-rc4 kernel to land relatively soon. We’ll of course rebase our Maverick kernel at that time.
Alpha 3 is Thurs Aug 5th which is about a month away. We are towering over the Alpha 3 burn down chart’s trend line, so please review the list of work items for Alpha 3 and start closing out tasks:

  • maverick-alpha-3

Lucid has been reuploaded with a proposed kernel that addresses a lot of ext4 issues. If all goes to plan this gets moved to updates soon enough to have a security update before Jul-28 which is the first point release.

Karmic is still not accepted because of the abstracted.debian backport. As there is a security update pending we need to eihter get someone take the risk and accept it into proposed, or we need to revert everything and get the minimal changes uploaded. Though the security update would be based on the version currently in updates, I think it would require a very careful merging back and together with the branches needing special care cause the whole validation of the builds being void.

  smb    tgardner, pgraner Would you think that Steve would take that risk if you asked him?
  tgardner    possibly
  tgardner    especially after we show that the binary packages are identical
  smb    tgardner, Would you take the action of talking to him, then?
  tgardner    smb, sure
  smb    ok thanks

Incoming Bugs: Bug day report

Community Bug days will resume next Tuesday. The focus will be on Fix Committed bugs. We will be looking to ensure that Fixes that were committed were in fact released so we can set their status appropriately. I’ll be sending out an e-mail announcing this tomorrow.
We’ll again be having the Team Bug Day over Friday and Monday as half days
