Note, this agenda item is finished for the Maverick development cycle and will be removed from the meeting agenda.

Status: Maverick

We've uploaded a new Maverick kernel, 2.6.35-21.31. This was to resolve linux-libc-dev ti-omap4 version conflicts which prevented any armel uploads.

Kernel Freeze is this Thurs Sept 16th. After Kernel Freeze, we transition to our SRU policy. I plan to upload our final Maverick kernel Sept 17th. There is little to no room for uploading any kernels beyond the 17th as the archive will freeze in preparation for Mavrick's 10.10 Release Candidate. Any patches which have any hope of landing the the 10.10 Maverick kernel need to be submitted and garnered the appropriate Ack's prior to the 16th.

We are again nearing being above the trend line for our overall burn down chart. We need to start closing out all remaining open work items. JFo, sconklin, apw, tgardner, jjohansen, smb: It appears you have open work items. Please review if your work item(s) can be marked as DONE or POSTPONED, else get er done.

    • There are very little to no verifications coming in for the Karmic and Lucid
      • proposed kernels. It looks like we need to start our own bug(them)-squad.
    • Accepting packages into proposed also faces some delays as pitti was on
      • holiday and it feels like there is no real backup there.
    • Karmic-fsl-imx51 sounds like being dead to me. We should probably make an
      • official announcement that we won't do any security updates on it anymore and see whether anybody cries.

JFo is continuing to work on removing the "regression-potential" tag from various processes.

Incoming Bugs: Bug day report

Due to much of the kernel team being in Taipei next week, the next bug day will be postponed to the following week.

Triage Status

The Kernel Triage Summit was a success. I am thankful to all of you who were able to make yourselves available for the sessions. Thanks to sconklin, diwic, apw and ogasawara for holding the sessions. I'll be blogging about the event and making the transcripts and survey available to those who were unable to attend.

sconklin

Thanks JFO, I thought we got good participation

JFo

any input you'd like to make on the Summit?

JFo

sconklin, I did too

JFo

I was well pleased

apw

just that we should touch those people who attended and showed interest again

JFo

I agree

apw

to follow up with them, and get their feedback individually

JFo

I'll be going though the transcript to see who was involved and get back with them

ogasawara

and we should follow up that the info dispersed lands in a wiki page somewhere

JFo

yes

apw

there was some very good audio info in there we must not lose ..

JFo

I think that is the most important bit here

JFo

apw, definitely agree

Open Discussion or Questions: Raise your hand to be recognized

  • As we will be in Taipei next week, I'd like to see about doing the bug chat on Thursday or Friday.

kstailey

go search on: ubunut nopat
