| jjohansen | morning: ppisati, apw | 08:26 |
| apw | jjohansen, late one for you | 08:26 |
| jjohansen | heh yeah, Ian had a late nap, so he will be up for at least a couple more hours so I am writing | 08:27 |
| smb | code or documentation? | 08:27 |
| jjohansen | smb: documentation after a fashion, its a paper | 08:27 |
| apw | anyone else running natty with an external monitor, and if so, are the indicators on the external monitor creaping off the right slowly over time? | 08:29 |
| smb | apw, Well I run it on my desktop... | 08:30 |
| apw | this is over days i am noticing it moving off, the power button me menu and clock have gone now, and a few pixels of the envelope now | 08:30 |
| jjohansen | apw: I get indicators being half drawn/covered and indicators disappearing, not seen going off the right | 08:30 |
| smb | But the indicators stay I think (if they show up at all, though that could have been because when booting there was an external networking issue) | 08:31 |
| apw | yestrerday i only had the date, no time from the time app, now the date is gone as well | 08:31 |
| ohsix | are any of the migration applets in the empty space | 08:32 |
| jjohansen | apw: fun, have you tried killing compiz, and or unity to see if it restores them | 08:32 |
| smb | Hrm, only got the time there ... and the settings thre brings up ... nothing | 08:32 |
| ohsix | er if it's unity then it's not a real panel and nevermind me :] | 08:33 |
| soren | apw: I do have an external monitor, but I switch between it and the laptop's LCD a couple of times a day, and I don't see this happen at all. | 08:33 |
| RAOF | apw: That's an *awesome* bug. That I've not experienced with my external monitor and oneiric. | 08:33 |
| apw | soren, yeah i suspect if i unplug and replug it'll get fixed | 08:34 |
| soren | apw: If only there was a way to find out... | 08:34 |
| apw | the one on the LCD is fine, its just my external | 08:34 |
| soren | :p | 08:34 |
| smb | Great, no changing time and date settings today... at least not with the ui | 08:34 |
| c2tarun | My kubuntu's performance is getting poor when I try to run my laptop on battery. Is there any way to improve it. I tried everything from power management and everywhere but, its not improving. I think its a kernel issue. Can anybody please help? | 08:50 |
| jjohansen | c2tarun: that is rather vague, you need to collect more information | 08:52 |
| c2tarun | jjohansen: what kind of information? | 08:52 |
| jjohansen | c2tarun: well, some firm performance figures showing how things are slower would be good | 08:54 |
| jjohansen | a bug with logs, etc | 08:54 |
| jjohansen | maybe some runs with powertop, latencytop, .. | 08:55 |
| c2tarun | jjohansen: hmm... how can I get log for getting system slow? I can feel it, opening any window and closing it, switching workspaces, openening widgets, everything is getting slower. :( | 08:55 |
| jjohansen | c2tarun: right, but your feel of things getting slower isn't something we can debug against | 08:58 |
| jjohansen | filing a bug, that collects the logs and system information gives some basic information to start from. | 08:59 |
| c2tarun | jjohansen: yeah, you are right, actually I was looking for something that can enhance my system's performance and not fix a bug. | 08:59 |
| ohsix | c2tarun: do you see intel_idle in the output of lsmod? | 08:59 |

| apw | ppisati, nice ... that'll help out stats | 10:48 |
| ppisati | apw: yep | 10:48 |
| ppisati | apw: i really didn't know of the existence of that page... | 10:48 |
| apw | ppisati, heh no worries, that page is really the stable teams input for cves | 10:49 |
| apw | and until karmic went dead fsl-imx51 at least was a rebase onto that, now its not we need some other solution | 10:49 |
| apw | and you are the solution there, so its a new requirement just since release | 10:50 |

| ghostcube | hi friend of mine has a 10.04 lts server with ecc ram and gets spammed by edac mc0 errors is there any solution | 11:13 |
| smb | ghostcube, Yeah, better RAM | 11:13 |
| ghostcube | heh | 11:13 |
| smb | But really, had the same and had to find the module that was faulty. | 11:14 |
| smb | Those messages tell you that there is a problem. Usually like correctable ecc errors. There is some hints about the location too, but it can be a bit tedious to map them to the physical slots | 11:15 |
| ghostcube | seems to be an edac bug | 11:17 |

| ghostcube | his ram isnt faulty he testet it | 11:17 |
| apw | ghostcube, in that bug all of the users seem to have indicated that quick boot was not clearing the memory out leading to the eec errors | 11:30 |
| apw | somone has to write to all of ram before eec can be safely enabled | 11:30 |
| ghostcube | yeah he tried this, but its still spamming errors its strange | 11:35 |
| ghostcube | one hint is just to blacklist edac modul | 11:35 |
| apw | yep stops reporting but they are still there i am sure | 11:35 |
| ghostcube | nope, he tried debian 6 hdd and bootet in slow boot now no more errors | 11:36 |
| ghostcube | hmm | 11:36 |
| apw | and does that kernel even have the edac module for his h/w ? | 11:37 |

| cjwatson | could somebody advise me on what to do about bug 785394? reserving 128MiB of RAM seems like an awful lot, and I wonder why the kdump kernel is taking quite so much memory to boot | 12:14 |
| ubot2 | Launchpad bug 785394 in grub2 "Hard-coded crashkernel=... memory reservation in /etc/grub.d/10_linux is insufficient" [Undecided,New] https://launchpad.net/bugs/785394 | 12:14 |
| cjwatson | It looks like it's OOMing while unpacking the initramfs ... hmm | 12:23 |
| cjwatson | $ zcat /boot/initrd.img-2.6.38-9-generic | wc -c | 12:23 |
| cjwatson | 44324864 | 12:23 |
| apw | cjwatson, the kernel en-toto is pretty huge, initramfs coming straight out of ram, both compressed and uncompressed | 12:35 |
| apw | cjwatson, do we use a standard kernel for the kexec kernel? ie. do we not strip the initramfs at all | 12:36 |
| cjwatson | I was hoping one of you lot would know | 12:38 |
| apw | i can have a look | 12:39 |
| cjwatson | it does have to mount the rootfs, so it seems to me that it would have many of the same requirements | 12:39 |
| apw | cjwatson, and the complaint there is that it won't fit into 64M in that bug | 12:39 |
| cjwatson | though maybe we could use MODULES=dep for the kdump initramfs, if it's possible for it to be different | 12:39 |
| apw | which with a 40M initrd, ... its not going to i suspect | 12:40 |
| apw | cjwatson, right that was what i was thinkng, you kexec initrd really doesn't need to be portable | 12:40 |
| cjwatson | I don't know if it's possible for it to be separate, though | 12:41 |
| apw | cjwatson, me either, shall i take a look ? | 12:41 |
| cjwatson | if you could, that'd be great | 12:41 |
| ppisati | lucid -proposed is stuck due to ec2 bug, right? | 13:08 |
| ppisati | i mean linux (2.6.32-32.62) | 13:08 |
| ppisati | https://launchpad.net/ubuntu/lucid/+source/linux/+changelog | 13:08 |
| herton | ppisati: yes, was put on hold because of ec2 issue | 13:36 |
| ppisati | herton: i see | 13:44 |
| apw | cjwatson, so its is a simple configuration to change which kernel kdump uses, defaulting to the current kernel, whats not so obvious is how we might maintain more than one initrd for a kernel via the normal mechanisms. i don't know if we could consider having on fixed kernel for kdump, as using the likely crashing one to dump itself is a little scarey | 14:29 |
| * apw pops out to collect a bag | 15:11 | |
| ppisati | what was the script that updated the changelog? | 16:37 |
| herton | ppisati: debian/rules insertchanges ? | 16:37 |
| ppisati | herton: i mean, the kteam tools | 16:38 |
| ppisati | herton: i think it's startnewrelease | 16:38 |
| JFo | I'm going to take a bit of an extended lunch. need to run some errands and check on my truck in the shop. | 16:38 |
| JFo | may not be gone very long, but wanted to let you know anyway :) | 16:38 |
| herton | ppisati: ah sorry, should be maintscripts/maint-startnewrelease | 16:38 |
| ppisati | herton: yes, that one | 16:39 |
| ppisati | herton: but it doesn't update the changelog | 16:52 |
| ppisati | uhm | 16:52 |
| herton | ppisati: yep, it just adds a boilerplate and insertchanges updates it after you commit your changes | 16:52 |
| ppisati | so... | 16:53 |
| ppisati | the process is | 16:53 |
| ppisati | startnewlrelease | 16:53 |
| ppisati | debian/rules insertchanges | 16:53 |
| ppisati | and then a commit UBUNTU: Ubuntu-2.6.X-Y.Z | 16:53 |
| herton | yep, from what I read from KernelMaintenance page in wiki | 16:56 |
| ppisati | ah, the wiki... :) | 16:56 |
| herton | ppisati: https://wiki.ubuntu.com/KernelTeam/KernelMaintenance | 16:56 |
| herton | but it seems to me we should always use maint-startnewrelease instead of startnewrelease rule, correct? (at least that is the procedure on stable proposed releases) | 17:09 |
| ppisati | herton: yep | 17:10 |
| ppisati | herton: maint-startnewrelease | 17:10 |
| ppisati | herton: apply stuff | 17:10 |
| ppisati | herton: and then close it | 17:10 |
| ppisati | i will tatoo these steps on my right arm so i won't forget it anymore | 17:10 |
| herton | hehe | 17:11 |
| * herton --> lunch | 17:11 | |
| smb | herton, ppisati maint-startrelease also gets you the abi files and applies them to the commit | 17:11 |
| ppisati | sorry, but still can't get my changelog updated | 17:27 |
| ppisati | e.g. http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=commit;h=538abd32e3b8b1fb152927c9dfbd7b43f301e377 | 17:30 |
| ppisati | i miss the modification to changelog that this commit has | 17:30 |
| ppisati | i know, i did it in the past | 17:30 |
| ppisati | but i don't remeber how i got the stuff there | 17:30 |
| ppisati | is there some magic script? or what else? | 17:31 |
| bjf | ppisati, i can walk you through it | 17:31 |
| ppisati | bjf: ok | 17:32 |
| ppisati | i know i did it | 17:32 |
| bjf | ppisati, did the "maint-startnewrelease" do the right things? | 17:32 |
| ppisati | yep | 17:32 |
| apw | ppisati, thats the fdr insertchanges t | 17:32 |
| bjf | did you do a "fdr insterchanges" ? | 17:32 |
| apw | that makes those changes | 17:32 |
| apw | - CHANGELOG: Do not edit directly. Autogenerated at release. | 17:32 |
| apw | - CHANGELOG: Use the printchanges target to see the curent changes. | 17:32 |
| apw | - CHANGELOG: Use the insertchanges target to create the final log. | 17:32 |
| ppisati | yes | 17:33 |
| apw | the key lines are those and need to be there | 17:33 |
| ppisati | that's what i get | 17:33 |
| apw | also does fdr printchanges print anything | 17:33 |
| ppisati | nothing | 17:33 |
| ppisati | empty | 17:33 |
| apw | as that is what gets inserted instread | 17:33 |
| ppisati | printchanges i mean | 17:33 |
| apw | ok then that likely means your previous commit has the wrong format | 17:33 |
| apw | printchanges looks backwards for the UBUNTU: Ubuntu-xxxx line | 17:33 |
| apw | and if thats not formatted right in the previous version it breaks | 17:33 |

| apw | i would ammend it yes | 17:35 |
| ppisati | ok | 17:35 |
| ppisati | let me try... | 17:35 |
| apw | bjf, you have a script for checking a tree tip has been correctly closed i think? | 17:35 |
| bjf | apw, yes, "verify-release-ready" | 17:36 |
| apw | ppisati, ^^ that is a good thing to use | 17:36 |
| ppisati | ok | 17:36 |
| ppisati | any way to amend the -16 commit? | 17:37 |
| apw | w | 17:37 |
| apw | ppisati, which one ? | 17:37 |
| ppisati | the broken one | 17:37 |
| apw | oh you mean the one which is 16 back from HEAD | 17:37 |
| ppisati | yes | 17:37 |
| apw | git rebase -i HEAD~16 | 17:37 |
| apw | then change the first line to edit | 17:37 |
| apw | then git commit --ame | 17:38 |
| apw | then git rebase --cont | 17:38 |
| * ppisati tries... | 17:38 | |
| bjf | ppisati, is that commit on master branch and was it in a release? | 17:42 |
| smb | sconklin, Hey Steve, you still need me to write a request to revert that max_pfn_mapped patch for Lucid and Maverick or will it be done just based on the failure | 17:42 |
| apw | bjf, its on an fsl-imx51 branch | 17:43 |
| bjf | apw, yes, but if that commit was part of a release, that history shouldn't be re-written | 17:43 |
| sconklin | smb I already reverted it for both | 17:43 |
| smb | sconklin, Ah ok good | 17:43 |
| apw | bjf, that specific commit is safe as it is now in a tag | 17:43 |
| bjf | ok | 17:44 |
| apw | and all of our arm kernels are rebase anyhow | 17:44 |
| apw | so that having a non-linearaity isn't a big deal | 17:44 |
| ppisati | everytime i close a release | 17:47 |
| ppisati | i need a tracking bug? | 17:48 |
| ppisati | i mean | 17:48 |
| ppisati | since there's a big pile of cve | 17:48 |
| ppisati | i wanyed to do it in steps | 17:48 |
| ppisati | so, now i'm doing this | 17:48 |
| ppisati | with some cves | 17:48 |
| ppisati | and i'll ask for a pull | 17:48 |
| ppisati | but i don't want an upload | 17:48 |
| apw | well we don't have to close the release to do a pull of it | 17:49 |
| ppisati | cool :) | 17:49 |
| apw | so just do the startnewrelease, add gthe patches | 17:49 |
| apw | and then just ask for a pull | 17:49 |
| ppisati | ok | 17:49 |
| apw | just leave it open | 17:49 |
| ppisati | k | 17:49 |
| ppisati | so, everytime we close, we upload and thus i need a tracking bug | 17:49 |
| apw | yeah thats a pretty accurate | 17:50 |
| bjf | ppisati, https://wiki.ubuntu.com/KernelTeam/StableHandbook/StablePatchApplication | 17:50 |
| bjf | ppisati, that explains all the steps | 17:50 |
| apw | ppisati, but for the meantime we can leave it not closed, | 17:50 |
| apw | we often don't have it closed in the repo | 17:50 |
| apw | with things sitting there waiting for more before the release gets closed | 17:50 |
| ppisati | ok, so let's see it the other way around | 17:51 |
| ppisati | i have a backlog of... | 17:51 |
| ppisati | 50? 60? patches waiting to be applied | 17:51 |
| ppisati | whats' the best policy? | 17:52 |
| apw | well you are applying about 15 a day | 17:52 |
| ppisati | s/policy/strategy/ | 17:52 |
| ppisati | yes | 17:52 |
| apw | i would apply them as i go, pushing the branch to zinc in my public repo ready for pulling | 17:52 |
| apw | then say weekly ask for it to be pulled | 17:52 |
| apw | when _all_ are applied we can close it and give it stable for handling out | 17:52 |
| ppisati | so the there will be just one big test session at the end | 17:53 |
| apw | yeah most of these cves are 1) generic and 2) already tested | 17:53 |
| apw | so the chance of regression for any which are just cherry-picks is pretty low | 17:53 |
| ppisati | ok | 17:53 |
| ppisati | deal | 17:53 |
| apw | i would test them at the end and cross my fingers :) | 17:53 |
| ppisati | actually i don't have the hw | 17:54 |
| ppisati | so from time to time i compile a kernel and "ship" it to someone to do, at least, a boot | 17:54 |
| apw | i would probabally produce one weekly as i went and ask #arm to test it | 17:54 |
| ppisati | k | 17:54 |
| apw | as it takes hours to build :( | 17:54 |
| ppisati | well | 17:55 |
| ppisati | i do it in about 15/20 minutes | 17:55 |
| ppisati | i cross compile | 17:55 |
| ppisati | all the other arm guys do native compilation | 17:55 |
| ppisati | but it's really too slow | 17:55 |
| * ppisati start a new recompilation... | 17:55 | |
