apwcyphermox, ogasawara, isn't there a fix in the batch on stable 3.0.6 something to do with failing to load builtin firmware on resume an ordering issue10:46

smbbullgard4, I think that is related to cleaning up network namespaces. Since that is time consuming it is done by a helper in batches.12:19
brendandsconklin, bjf - is there a tag i can rely on to find bugs that were regressions caused by -proposed kernels?12:19
bullgard4smb: Thank you very much for explaining.12:23
smbbullgard4, glad if it helps12:24
bullgard4Yes, it does.12:24
hertonbrendand: regressions in -proposed should be tagged as regression-proposed, not sure everything is being tagged correctly though12:32
brendandherton - yeah, i got some though now. thanks12:38

smoseris anyone able to tell me i'm a complete moron, and this is not possible https://bugs.launchpad.net/ubuntu/+source/linux/+bug/84586413:18
ubot2Launchpad bug 845864 in linux "painfully slow recharge time" [Undecided,Confirmed]13:18
smoseror at least that it could not be kernel related.  13:18
smoseri would not have thought it could be, but I utlemming and both noticed this on our laptops during oneiric.13:19
tgardnersmoser, perhaps its a good question for cking13:22
smoserif someone else had not started seeing the same thing, i would hvae thought that my battery was just beginning to fail.13:24
tgardnersmoser, I wonder what role the EC has in charging your battery?13:24
smoserEC ?13:25
* cking looks at the bug13:25
tgardnersmoser, its an embedded controller that does a lot of stuff behind the scenes.13:25
ckingI'd suggest recharging it when the machine is off and seeing what happens - if it still charges slowly it's a battery problem13:27
ckingotherwise, if it's running and slowly charges I expect some process or kernel power management feature is sucking power causing the recharge to take forever13:29
tgardnercking, that would explain the differences between kernel versions13:29
smosercking, well, 'top' doesn't show anything, and the system does not otherwise appear heavily loaded at all.13:30
ckingthe other option is to boot with an older kernel and use the oneiric user space to factor out if it's a kernel issue or not13:30
smoseryeah.13:30
smosercking, thanks. 13:30
ckingbut first I'd see how long it takes to charge when not running - that's an easy test and will show you if it's H/W related13:31
smoserwell, yeah, except turning it off means i can't use it for work.13:31
smoserbut it is a nice day here, and golf could fill that time :)13:31
cking:-)13:31
ckingsee how it charges at the end of the working day ;-)13:32
ckingsmoser, the data from /proc/acpi/battery/ comes from the ACPI _BST, _BIX and _BIF methods and these basically read the battery status via the EC, so I doubt that this is broken13:34
cking..it's fairly straight forward code in the kernel. The only explanation is the either something is chewing up the power or the EC is doing the wrong thing13:35
cking..or the battery is not happy13:35
smosercking, yeah. i would have assumed bad battery. but utlemming complained about this to me right after he upgraded to oneiric without me leading him at all.13:37
smoserbut, i'll check when power off and such.13:37
smoserthanks for your  help.13:37
ckinghrm, gitweb is sucky and slow today on zinc13:54
ckingswapping like crazy13:55
tgardnercking, yeah, zinc is kinda under powered for some things13:56
ckingwell, it's all blocked in I/O and swapping like mad, so more memory would be handy for it13:57
tgardnercking, indeed13:58
* ogasawara back in 2014:10
bjfbrendand: no, at this time there really isn't14:52
ogasawaraapw, smb: have either of you tried installing this linux-image-extra virtual package?15:02
apwnot since you integrated it, no, whats up15:02
smbogasawara, Not yet15:02
ogasawaraseems to have dependency issues15:02
smbogasawara, But it should be a relative quick exercise to try15:02
apwogasawara, what happens15:03
apwluckily its an opt in package, so even if its bust it can wait till the first SRU upload15:03

ogasawaraThe following information may help to resolve the situation:15:03
ogasawaraThe following packages have unmet dependencies:15:03
ogasawara linux-image-extra-3.0.0-12-virtual : Depends: linux-image-3.0.0-12-virtual (= 3.0.0) but 3.0.0-12.19 is to be installed15:03
ogasawaraem: Unable to correct problems, you have held broken packages.15:04
ogasawaraonly discovered it cuz I was trying to test out a meta package for it15:04
smbHm, linux-image shoudl exist...15:04
apwogasawara, i am unsure how that didn't happen to me, but it looks plain wrong15:05
apwit should be the other version in teh control.in15:05
apwogasawara, you gonna look at it or should i15:06
ogasawaraapw: I can investigate15:06
smbogasawara, ok get the same here15:06
apwi think its a single line change to control.stub.in or stub.d/virtual15:07
ogasawaraapw: am also gonna send out a patch for an -extra's meta package15:07
apwto switch the version number round15:07
smbapw, So to get the -12.19 added?15:09
apwyeah, it must mention the wrong version variable there15:09
smbprobably adding ABINUM helps15:11
smbhm no15:11
smbwould only be 12...15:11
ogasawarait looks right to me15:11
ogasawaraI'm missing something15:11
apwthere is a proper15:11
apwthere is a proper longer version number isn't there?15:12
ogasawaraapw: must be, now to find the variable name for it15:12
hertonbjf: well, https://wiki.ubuntu.com/Kernel/BugFocus bugs says regressions in -proposed should be tagged as regression-proposed15:13
herton(refering to brendand's question)15:13
apwogasawara, doesn't look like we have the specific version as a variable, only PKGVER and ABINUM15:18
apwogasawara, the headers depedancy is just to the unversions package name, we could do the same i suspect and be fine15:18
apwDepends: ${misc:Depends}, coreutils | fileutils (>= 4.0), SRCPKGNAME-headers-PKGVER-ABINUM, ${shlibs:Depends}15:19
ogasawaraapw: ack, I'll try that and test15:19
smbapw, Its likely new that you need to be in lockstep with a specific kernel version...15:19
apwsmb, likely though its officially abi compliant, so it shouldn't matter in theory15:19
bjfherton: that may be, but who has been doing the tagging?15:20
smbapw, Probably loadable. Though it may have strange behaviour as they are really tightly coupled15:20
smbapw, On the other hand every build will produce both anyway15:20
hertonbjf: no one that I know, that's why I told probably not everything is tagged correctly. I guess we should be doing it when we identify a regression15:23
apwogasawara, it wouldn't be hard to add a variable too15:24
bjfherton, and that's why i replied that at this time there isn't one, no one is applying it15:25
hertonbjf: shouldn't we be applying it anyway?15:26

tgardnerwhere one half is split onto his keyboard15:29
brendandbjf, herton - does regression-proposed get added by apport if a user is running the -proposed kernel?15:33
=== zz_bigbash is now known as bigbash

bjfbrendand: i don't think so, http://people.canonical.com/~kernel/reports/regressions-proposed-report.html shows bugs marked regression-proposed15:35
bjfbrendand: there just aren't enough on that list for it to be accurate15:35
brendandbjf - true, there's only 39 there last time i checked15:36

apwok not beer, but an actual waterfall coming through his fuse box!!!  so i think smb will be away for some time15:44
apwogasawara, tgardner ^^15:44
ogasawarawhoa, that's not good15:45
brendandbjf - btw, we have a session at UDS about improving coverage of certification testing for SRUs. Your feedback is welcome : https://blueprints.launchpad.net/certify-planning/+spec/hardware-p-cert-sru-coverage15:45
brendandsconklin too ^15:46
tgardnerapw, did local construction efforts redirect a local river into his house ?15:46
brendandbjf - i got your feedback on the wiki page15:46
sconklinbrendand, thanks, subscribed15:47
bjfbrendand: subscribed15:49
brendandsconklin, bjf - do you guys have some time for a brainstorm about where our efforts might be best focused?15:49
brendandsconklin, bjf - we're already sort of set on improving wireless, video and audio coverage so we'd be focusing on identifying use-cases within those areas15:50
bjfbrendand: the three areas users have the most issues with: wireless, audio, graphics15:50
brendandbjf - agreed then15:51
sconklin+115:51
bjfbrendand: you should be working with QA, they should be hitting the same areas, i'd expect the two teams to be able to share tests, they may be focused on depth while your focus is breadth15:52
brendandbjf - yes, fewer tests but on a broader variety of hardware15:53
brendandsconklin, bjf - are you guys ok with taking some time tomorrow afternoon to discuss this then? we'll engage with QA, but also looking for your input15:54
bjfbrendand: i'm pretty much always available to talk about testing the kernel15:55
bjfbrendand: are you thinking mumble, irc or email ?15:56
bjfbrendand: i personally like a "paper" trail15:56
sconklinwhat he said15:57
brendandbjf - i'd go for IRC15:57
sconklinbrendand, how about in the #ubuntu-kernel channel15:59
brendandsconklin - no reason not to keep it public16:00
brendandbjf, sconklin - i'll schedule something tomorrow just to make sure everyone's in the same place at the same time (there are other folks from my team interested in participating)16:01
bjfbrendand: sounds good, should be able to pop in here and start anytime, unless there's some hot discussion raging :-)16:01
sconklinsounds great, looking forward to it.16:02
