ARM Status

  • Marvel (mvl-dove)
    • Nothing new this week.
  • Texas Instruments (ti-omap)
    • Tim uploaded 2.6.35 ti-omap4 kernel to Natty branch
    • Linaro Natty kernel can boot up on both OMAP3 and OMAP4 boards with the same
      • Natty minimal root filesystem.
    • Bug 633227: On-The-Going.
      • - I found the same issue on Linaro 2.6.37 based Natty kernel, which is close to mainline for OM - So, mainline also has the highmem issue for OMAP4 SMP system

Bugs with Patches Attached:140 (down 2)

I added 2 new items to the above metrics. The Lucid and Maverick updates milestoned bugs. I think that these may be useful for some of you, such as the SRU Team. I am open to your feedback.

Blueprints: Natty Bug Handling

Nothing to report. All inprogress work items are still in various states of flight. Smile :)

Blueprints: Kernel Configuration Review

HZ report has now been produced, it is showing that moving HZ from 100 to 1000 has a between 10-12% CPU overhead under high load, rendering it unsuitable for any sort of server workload, further analysis of these results ongoing. All other changes are applied an uploaded.

Blueprints: Enhancements to the firmware test suite

Changes to fwts (natty development branch):

  • klog: IO APIC IRQ kernel log checks, use more regexs to allow fuzzier [Firmware] bug checking
  • fix ARM and PowerPC FTBFS
  • add --lp-tags-log, -j, --json-data-path, -u, -utils options
  • expand --lp-tags tagging to all applicable tests
  • Initial UEFI support:
  • detection for BIOS/UEFI firmware
  • rename e820dump to memmapdump as it applies to UEFI too
  • e820 lib reworked for BIOS + UEFI firmware
  • smbios test: fix for UEFI
  • fwts USB stick image: reworked to use latest fwts dev version, tweak dialog progress bar

Blueprints: Handling of Deviations from Standard Kernels

Nothing new

Blueprints: Review of the Stable Maintenance Process (sconklin / bjf)

The Stable kernel team has prepared and uploaded kernels for all supported releases. These contain a number of non-critical CVEs.

These kernels are all built, and are awaiting copying to the -proposed pocket, at which time the Verification phase of the kernel release will begin. This is part of the process described here:


I expect that these kernels will be in -proposed by tomorrow, possibly within hours of now.

We have been developing and refining tools and processes as we go, and this has been the biggest challenge in the new process. All changes are being documented on The wiki page linked above

It's possible that this release can be published by Dec 17th, depending on testing resources and when we begin verification testing.

It is unlikely that we will begin another stable kernel cycle before the beginning of next year.

Security & bugfix kernels - Maverick/Lucid/Karmic/Hardy/Dapper (sconklin / bjf)





Dapper: Kernel


Hardy: Kernel



Karmic: Kernel


= mvl-dove


= ec2


Lucid: Kernel





= mvl-dove


= fsl-imx51



= ec2


= lts-backport-maverick

Maverick: Kernel


= mvl-dove


= ti-omap4


Blueprints: Ubuntu Kernel Delta Review

14 of the 19 personal patch reviews are now done. The remainder have been pushed out to natty-alpha-2, but none are release critical.

Blueprints: Kernel Version and Flavours

Preliminary uploads of ti-omap4 branches for Natty have now occured, this will form a basis for the natty development. Still waiting on ARM CD image testing. A number of minor work items moved out from natty-alpha-1.

Status: Natty

The main distro kernel is now at 2.6.37-8.21 (v2.6.37-rc4 based). This kernel brings fixes for a large number of 'boots to black' failure modes with the grub2 graphical handoff. Testing on the graphics boot changes is looking good on this kernel. v2.6.37-rc5 has already released and will be uploaded shortly.

Incoming Bugs: Regressions

Incoming Bugs

  • 32 Natty Bugs (up 13) 1113 Maverick Bugs (up 25) 1110 Lucid Bugs (up 1)

Current regression stats (broken down by release):


  • 25 maverick bugs (up 2)
  • 83 lucid bugs (up 2)
  • 6 karmic bugs (no change)
  • 0 hardy bugs (no change)


  • 175 maverick bugs (up 8)
  • 198 lucid bugs (down 1)
  • 40 karmic bugs (no change)
  • 2 hardy bugs (no change)


  • 13 maverick bugs (no change)
  • 6 lucid bugs (no change)
  • 1 karmic bug (no change)

Incoming Bugs: Bug day report

Today's bug day is covering regression-update bugs. I sent the wrong information earlier today, but there are 118 bugs that need to be looked at, the majority of which will need to be tested against the latest released version and the current version in development. I sent out an e-mail today concerning the day. I've also posted a blog post on our voices page as a reminder. The next bug day will be next week. I'd like for that one to focus on regression-proposed bugs since the ones that I have on my list have been there too long to be seriously considered as legitimate bugs in the proposed queue. I'm open to your feedback and will plan to send out the details if everyone agrees on this focus.

Triage Status

I have been given further guidance on Bugs with patches by pete and I have begun, albeit slowly, to move through that set of bugs. I hope to have a significant portion of them addressed this week so that the reporting item above should reflect a noticeable difference. I am continuing to work on the script gathering bugs based on a tag as well as the overall hot list script and the script that replaces a tag with another. All of those efforts are intertwined since the logic is very similar. I expect to have some of them finished by the end of this week barring any major roadblocks. Smile :)

Open Discussion or Questions: Raise your hand to be recognized

  • Are the uploads going to make it to -proposed this week?
    • The SRU team is actively working on them as we speak
