ckingif it carries on like this I will move to a different ISP09:21
ckingwell, 3G seems to work well enough for irc and email and they hope to get it fixed by 1pm09:21

smbPrepare for the worst... Well on the other hand. Distractionlesser day09:22
ckingwell, less mumble traffic today ;-)09:23
apwcking, testing your 3G ?09:23
smbcking, Right, which can be a big source of distraction09:23
ckingapw, 3G seems to work quite well from my loft .. not bad really09:24
smbcking, while you are still there, have you had luck catching panics with netconsole before?09:24
ckingsmb, I believe not, but I haven't used it much09:25
* cking can't recall 09:25
ckingthe plus side is that it isn't too tricky to rig up09:26
smbcking, Ah ok. Could not remember whether you had been using that at all09:26
smbThought I had something... though did not see any message which may say I did not09:26
ckingI've used it for debugging - but I'm not sure if I got any panics captured using it 09:26
smbcking, <hope>is there a setup rune on your blog?</hope>09:28

brendandcan anyone think of a good reason why the first cpu core would be offlines by default on say a 16 core system?14:46
brendandi've seen it on two systems. two different models of processor, the common thread being they are both 16 core14:48

apwhallyn, another issue ?15:20
hallynapw: apparmor returns -EINVAL on any overlayfs file15:20
hallynapw: it's possible this is purely apparmor's problem and I should hit up jjohansen again, but I wasn't sure15:21
apwhallyn, cirtainly we should get jj involved yes15:21
apwhallyn, gawd what does this drivel even mean ...15:27
hallynthe code, or my report?15:28
apwhallyn, this is a case of it making sense to the reader, if they get lxc and apparmor i suspect15:29
apwhallyn, so #3 does that say that you don't need a container here15:29
hallynright15:30
hallynjust mount an overlayfs, have an enforcing apparmor policy, boom15:30
hallynwhich means, i'd expect libvirt to fail on livecd15:30
hallyn(untested)15:30
apwi'd not expect you to want to use libvirt on a live cd, but hey15:31
apwhallyn, anyhow i'll poke jj and see what this means15:31
hallynapw: tahnks.  sorry, yesterday i was pretty sure it was just another missing hook, but now i'm thinking not...15:32
* ogasawara back in 2015:33
jjohansenhallyn: hrmm, that sounds wrong, give /me needs to get kids off to school and then I can look at it15:39
apwhallyn, what does this capabilities list even say ?  is that essentially "allow all" ?  the one in #3 ?15:40
apwjjohansen, lets talks when you get back15:41
jjohansenapw: sure.15:41
apwjjohansen, you can teach me what this gibberish in dmesg means15:42
jjohansenapw, hallyn: apparmor only return EINVAL in a few places15:42
hallyni see, the gibberish is my policy :)15:43
hallynanyway we don't want to allow all - we'll want to deny cap_mac_admin and cap-mac_override in final policy15:43
apwhallyn, yeah i was trying to work out if the policy there was actually essentially a noop15:48
hallynapw: the one in the example was meant to be a noop15:54

ogasawaralooks up to date -> http://reports.qa.ubuntu.com/reports/kernel-bugs/reports/rls-p-tracking-bugs.html16:45
bjfskaet, i also looked at the timestamp on the file on cranberry and it is this am16:45
ogasawaraout of date -> http://reports.qa.ubuntu.com/reports/kernel-bugs/reports/rls-mgr-p-tracking-bugs.html16:45
bjfogasawara: yes, the second is out of date16:46
skaetbjf,  its the second one (rls-mgr-p-tracking) I'm trying to get working again.  :)16:47
bjfskaet: ok, that wasn't clean. fixing now16:48
* skaet thinks we need to rename those reports and the tags.... later though. :P16:48
bjfskaet: it was turned off several weeks ago, i've re-enabled it and it's running16:48
skaetbjf - any idea why it was turned off?16:49
bjfskaet: didn't think anyone was looking at that one, just the other and it was sucking cycles16:49
bjfskaet, it will now run with all the rest16:49
bjfskaet: or maybe i turned it off last week when debugging that issue, and just forgot to re-enable it16:50
bjfskaet: anyway, it should be fixed now16:50
skaetbjf,  thank you.   the rls-mgr-p-tracking one is where folks are tagging things that should be considered.   rls-p-tracking is only those things that teams COMMIT to fix. 16:50
bjfskaet: (as soon it regenerates)16:50
skaetthere's a delta between the consider and the commit - both are useful.16:51
skaethowever - the tags do seem to be causing confusion.16:51
skaetmaybe a transition to something like consider-p-tracking,  commited-p-tracking at some point in the future?16:52

* jsalisbury see pulseaudio crash, then mumble freak out and consume 100% cpu, spinning on sched_yield()17:08
hallynmaybe thats what used to happen to my banshee17:08

ohsixdoom to he who uses sched_yield17:09

ohsixwhy can't they just sleep :[17:09
skaetThanks bjf!   Yup,  now I can see all the new packages that need to be sorted into teams too.  :)   17:11
ohsixjsalisbury: that looks like a pulse bug (the _yield thing, it's done a lot to wait on async queues, something has to go really wrong though)17:22
ohsixi guess pulse crashing is wrong enough, but it should be getting a sigpipe or something in the client when it happens17:22
jsalisburyohsix, hmm, maybe mumble likes to do things really wrong 17:23
ohsixhow pulse exited is probably interesting too, killed by rtkit, killed by its own rttime quanta or killed by a crash17:23
jsalisburyohsix, yeah, I plan on digging deeper17:23

ohsixi dunno what else could be calling _yield then, mumble only does in some speex performance test, not in the program proper17:25

tgardnerapw, I'm wondering how you use debian/scripts/misc/insert-mainline-changes ?18:08
apwinsert-mainline-changes debian.master/changelog v3.2.3 v3.2.2..v3.2.318:09
apwtgardner, something like that18:09
apwit allows you to specify the range in case you don't have the tags, so you can use sha1s if you need to18:10
apwtgardner, then you'll find git diff shows what its done to changelog18:10
tgardnerand you've documented this where ?18:10
apw:))18:10
apwtgardner, if there is somewhere you'd recommend, i can add it18:11
tgardnerhow abiout just getting it in the help message with a quick example18:11
apwyeah that would have made sense18:11
apwtgardner, i'll do it now and push it up, you can cherry it onto your rebase before you push18:12
tgardnerapw, so all I got from that was '* rebase to v3.2.3'. does that mean there were no buglinks ?18:13
apwtgardner, thats the implication if i didn't mess up the incantation :)18:13
* apw checks18:13
apwtgardner, indeed no buglinks so ... it did nothing, but thats not always the case18:14
apwand i assume ogasawara used it for the 33-rc1 rebase, which would have had a bunch i bet18:15
apwogasawara, which reminds me, we probabally need to include -v when we upload the first one into Q if we want those buglinks to work18:16
ohsixanyone know offhand of any of the ld_preload hacks to lessen the impact on the file cache for cron jobs and such? akpm had something on userweb.kernel.org but it's not there anymore18:17
ohsixoh neat i think i found a descendent of it on google code18:19
ckingohsix, is this what you are referring to? http://smackerelofopinion.blogspot.com/2009/06/does-prelinking-speed-up-boot-times.html18:26
ohsixcking: not unless it uses an LD_PRELOAD hack to keep read pages out of the page cache (i'm trying to get a duplicity cron job that's run hourly to not completely destroy interactivity for most of the hour between runs)18:28
ckingohsix, in which case, it's not what you're looking for18:28
ohsixthere was a flag added a while ago but it was wired up to a no-op, dunno if this got in http://lwn.net/Articles/449420/18:29
ohsixlooks like they made rsync use it already too, librsync doesn't (or can't, don't think it deals with files directly)18:30
tgardnerapw, have you pushed? vanilla 3.3 don't build anyways. working on figuring out the missing dependency18:32
tgardner3.2.3*18:32
apwtgardner, waiting on atime wrappage update time disk hell18:33
ckingapw, that always seems to coincide with beer time doesn't it?18:33
apwi think there is a cirtain alignment :/18:35
ohsixbummer, _NOREUSE is still a no-op18:37
* cking -> EOD18:39
apwtgardner, pushed18:39
ohsixheh posix_fadvise DONTNEED on linux trashes all the file pages no matter who has it open, that seems fun18:45
vanhoofogasawara: heya19:03
brycehbjf, you might adjust your kernel bot to not bug reporters if the kernel-handoff-graphics tag is present; generally we only add that when we pretty much already know the bug's disposition (and usually have found a fix)19:06

bjfbryceh: you have an example bug?19:10
tgardnerogasawara, pushed precise master-next with v3.2.3 stable. there is likely more carnage yet to come as I expect Greg will release v3.2.4 shortly due to compile issues.19:13

vanhoofogasawara: quick question on the cw-3.2 lbm update for oneiric19:28
vanhoofogasawara: will what's in -proposed now have to land before we see the fix in 923900 land?19:28
* vanhoof is not exactly sure how the lbm cadence works19:29
ogasawaravanhoof: hrm, it could go up separately, but I suspect bjf/herton will just want up coordinate it with the kernel in -proposed.19:31
hertonogasawara, vanhoof: I't not sure how it was done previously, may be we could shove this new version into current -proposed19:34
bjfherton, i'm fine with pushing it19:34
ogasawaraherton, vanhoof: it looks like https://launchpad.net/ubuntu/+source/linux-backports-modules-3.0.0/3.0.0-16.8 has already been uploaded to -proposed19:34
vanhoofherton: yeah this is the first time i've encountered a bug like this 19:34
ogasawaraherton, vanhoof: so I suspect it'll move to -updates at the same time as the kernel19:35
vanhoofogasawara: and then the next upload would be another update to lbm to factor in bug 923900 ?19:36
ubot2`Launchpad bug 923900 in linux-backports-modules-3.0.0 "Enable iwlwifi drivers for compat-wireless v3.2 backports" [Undecided,In progress] https://launchpad.net/bugs/92390019:36
hertonyes, 3.0.0-16.8 is the current one in -proposed, as it didn't move yet to -updates (and I think it will wait for more 1 week for it), I think a new lbm could be copied so it gets along when -proposed moves19:36
hertonwe just would have to ask an archive admin to copy a new lbm over proposed again19:37
ogasawaravanhoof: yep, sorry.  we would need another upload LBM to resolve 923900.  but as herton just mentioned, they should be able to shove that up now.19:37
vanhoofogasawara: no worries, and thanks for the info :)19:38
ogasawaraherton, bjf: I assume LBM is not under as strict a QA schedule as the kernel since it's an elective install.  and I'm sure vanhoof is willing to give you immediate testing feedback.19:39
vanhoofand beer19:39
bjfogasawara: i don't think QA knows LBM exists19:39
hertonyeah, never saw anyone mentioning QA of lbm. I'll prepare a new lbm, and ask it to be copied then to -proposed. I already have to ask for a new linux-meta copy for maverick also, because of the missing omap/versatile metas19:40
vanhoofherton: bjf: just poke me and I can get some widespread testing done quickly19:50

ogasawaratgardner: i was doing test builds yesterday and all seemed fine20:13
ogasawaratgardner: but I didn't look closely at the logs to see if anything was amiss20:13
tgardnerogasawara, I need to make sure that the resolvconf issues aren't preventing package updates.20:13
