Bugs with Patches Attached:126 (down 2)

Blueprint: kernel-maverick-apparmor

Bug 615947 - Fixed and updated regression test suites. Will get a patch out to kernel list tonight. User side updates to log parsing should be commited today or tomorrow.

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

LTS backports are tracking Maverick at 2.6.35-14.20

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

Bug #612875 virtual kernel in EC2 only boots from pv-grub. This is going to require user image creation work on packaging up an aki. Basically we need to strip the bzImage header off leaving only the gzipped vmlinux. This is low priority and probably won't be done. Bug # 574910 High load averages on Lucid while idling. This is in the Xen patchset, and I have a new kernel being built to test later today. I have 4 bugs that I haven't really gotten a chance to look at yet, and anyone who wants is more than welcome to them. Bug #606373 cloud-init output does not get to console when booted with and ramdisk. This looks like it is a variation on Bug #431103, except with the pv-ops hvc console instead of xvc0. Bug #613083 user-data is corrupted inside metadata service Bug #613022 ssh daemon hangs after publickey packet sent Bug # 613273 kernel panic on ec2 in system_call_fastpath

Blueprint: kernel-maverick-bug-handling

Nothing to report

Blueprint: kernel-maverick-upstart

Looking into an issue wherein console opens are being failed. Believe we have the issue diagnosed, a solution is in progress. Nothing else to report.

Blueprint: kernel-maverick-bios-test-automation

  • Changes since last week:
    • update fwts from 0.17.2 to 0.17.9 in maverick universe
    • USB key images at http://kernel.ubuntu.com/~kernel-ppa/testing (with help from bjf)

    • --P, --power-states category for S3 S4 tests
    • better AML parsing for hpet_check test
    • nx test: print out model number as integer (fixes segfault)
    • fix typos in man page

Status: Maverick

Since our Maverick kernel is now rebased on v2.6.35, we've started applying 2.6.35.y pre-stable patches. We'll keep Maverick in sync with the 2.6.35.y releases as they become available. Maverick Beta is Thurs Sept 2nd, ie ~3weeks away. Also keep in mind that Kernel Freeze is Thurs Sept 16th, ie ~5weeks away. We are above our Beta burn down chart's trend line but I'm not too worried as most of the open tasks are investigative in nature and not release critical.

  • fsl-imx51 has not been released in security this time as there had been problems with certain board revisions. We need to add one more SRU patch before next upload. We won't do that until we get feedback on the patch actually fixing the issue.
  • For Lucid a new proposed kernel which addresses a few priority issues has been uploaded and will get accepted into proposed as soon as the CD images for the point release are settled.

Incoming Bugs: Bug day report

Today is the Bug Day. We are focusing on bugs incorrectly listed as new. These will be put in the correct state and their subsystem tag will be added. I'll update next week with the result. We will continue to have the Team Bug Day to address the Top 50 list as half days on Friday and Monday, as these seem to be working out very well. Reviewers, please take a look at your needs-review lists and help us keep the process moving. I will be in Oxford, UK next week, so I'll send my metrics update to bjf via e-mail.

Triage Status

Great work is being done daily in our bugs due to many folks from other userspace systems helping to triage as well as providing numerous nuggets of wisdom to the bug reporters themselves. We met simar during last weeks meeting. simar is workin on expanding multitouch knowledge and looking over those bugs. holstein has been looking at kernel bugs and is currently undergoing bug mentorship with hggdh. I have been mentoring chazn85 also, focusing on tagging and requests for information. chazn85 has also been looking through our wiki documentation to bring inconsistencies to my attention. I'd also like to thank charlie-tca for all of the work he has been doing ion kernel bugs as well.

Open Discussion or Questions: Anyone have anything?

  • We will be having our Monday bug chat on Friday at the usual time since JFo will be in Oxford and unavailable next week.
