[12:26] <ubotu> Schedule for Europe/Berlin: 24 Jul 17:00: Kernel Team | 25 Jul 14:00: Edubuntu | 25 Jul 22:00: Xubuntu Developers | 26 Jul 17:00: Ubuntu Development Team | 27 Jul 14:00: MOTU Team | 31 Jul 17:00: Ubuntu Server Team meeting
[04:59] <zul> hello
[05:02] <BenC> ok, hello everyone
[05:02] <BenC> This is the Ubuntu Kernel Team meeting, our agenda is at https://wiki.ubuntu.com/KernelTeam/Meeting
[05:03] <BenC> Unfortunately, Kyle and Tim are at UbuntuLive and wont be attending, which shortens our agenda quite a bit
[05:04] <BenC> A few highlights of recent things we've been working on include UME kernel (amitk), and liveCD memory issues (pkl)
[05:05] <BenC> amitk: would you care to elaborate on some of the work you're doing with UME, and plans for power management improvements?
[05:06] <BenC> ah, amit has lost connection :)
[05:07] <BenC> While he's regaining that connection...any questions from community folks?
[05:07] <zul> not me
[05:07] <zul> I didnt prepare anything at least
[05:07] <BenC> this is going to be a short meeting, so we'll have time for this sort of thing :)
[05:08] <zul> oh yeah ill try to get to vserver this week what about openvz?
[05:08] <ScottK> Would anyone be willing to work on kernel bug triage while we wait?
[05:09] <BenC> zul: openvz looks like it may miss the gutsy release, but we are discussing possibilities with them
[05:09] <zul> ok
[05:09] <BenC> they are still based on 2.6.20 kernel, and the reject list is huge against 2.6.22
[05:10] <zul> and im not touching it ;)
[05:10] <amitk_> I dropped out...
[05:10] <BenC> ScottK: you're more than welcome to do that at any time :)
[05:11] <BenC> amitk: saw that on the other server...we were just discussing some open topics, but I had wondered if you wanted to give an update on UME and/or power savings work in gutsy
[05:11] <ScottK> BenC: Unfortunately for me, when it comes to the kernel, I'm more of a triagee than a triager.
[05:12] <BenC> ScottK: heh, a good time for that is bug days, in which we'll have a kernel team person actively helping and working on kernel bugs
[05:13] <ScottK> Sure.  Just thought maybe it would be a target of opportunity while waiting.  No problem.
[05:13] <amitk_> nothing big really - UME kernels seem to work on the menlow platform
[05:13] <amitk_> https://blueprints.launchpad.net/ubuntu/+spec/power-management-in-ubuntu has been modified to be more focused for gutsy
[05:14] <amitk_> and I am now working on splitting up the test cases for laptop-testing group in order to revive it
[05:14] <BenC> excellent, the laptop testing sounds really promising
[05:15] <BenC> amitk: have you contacted heno about the test infrastructure yet?
[05:15] <amitk_> no I haven't. I will do that right away
[05:16] <BenC> hopefully they've been working on the backend already, and it will just be a matter of plugging in the explanations and reporting procedures that you come up with
[05:16] <BenC> pkl_: you've been tasked with livecd memory usage problems, and with virtualization (mainly xen)...how's that coming?
[05:17] <amitk_> I would also like to put out a call for volunteers to do some powertop hacking (www.linuxpowertop.org)
[05:17] <pkl_> BenC: currently suspended, looking at the critical #126964 bug.
[05:18] <pkl_> That's the liveCD corruption and hang bug.
[05:18] <BenC> ah, right
[05:18] <pkl_> The hang I traced last week to a race I put into Squashfs in April.  Fixed.
[05:18] <BenC> been able to point the blame at anything specific yet?
[05:19] <BenC> good, nice work
[05:19] <pkl_> The corruption bug is much rarer, but very nasty.
[05:20] <pkl_> Unfortunately the available debug info proved impossible to track this down.
[05:20] <BenC> pkl_: would this benefit from crashdump?
[05:20] <BenC> I could probably write up something, and create an ISO which can handle crashdumps capturing
[05:21] <pkl_> I have put in a lot more non-invasive (i.e. no spewing rubbish to dmesg) logging via a psedo file (debugfs), and got some good debug info yesterday,
[05:22] <pkl_> I believe I know the execeptional set of circumstances which cause the bug.  It looks like an undiscovered race condition in the Squashfs fragment cache code.
[05:22] <BenC> ok, if you need more extensive testing, would be good to talk heno about putting out a call for that
[05:22] <BenC> otherwise, keep up the good work you're already doing
[05:22] <pkl_> Debugging is currently ongoing.
[05:23] <pkl_> Yeah, I've been up to 6am most nights..
[05:23] <pkl_> As it's Squashfs I have a vested interest in fixing it, and a certain responsibility :)
[05:24] <BenC> pkl_: sleep becomes a luxury at times :)
[05:25] <BenC> Well, unless there's some other topics people want discussed, this meeting is at an end
[05:25] <BenC> I'll give a short pause from the chair...
[05:26] <BenC> And, that's it folks :)
[05:27] <BenC> thanks everyone, have a good week and so you all in two weeks for the next meeting
[05:28] <amitk_> bye
