| ali1234 | does console-kit-daemon really need to use all spare cpu time or is it a bug? | 07:37 |
|---|---|---|
| === ericm is now known as ericm-afk | ||
| lool | ali1234: it's a bug | 08:49 |
| lool | ali1234: What environment do you see this in? | 08:49 |
| ali1234 | lool: i'm running on omap850 after using the "root from scratch" script with --seed=lxde,gdm | 08:50 |
| lool | ali1234: Could it be an option missing from your kernel? | 08:51 |
| ali1234 | yes, it certainly could. but which one? | 08:51 |
| lool | ali1234: I would strace consolekit to see whether it's failing a syscall or something like that | 08:51 |
| lool | ogra: Did you ever see 100% used with CK? | 08:52 |
| lool | I didnt ever see this | 08:52 |
| ogra | nope | 08:52 |
| ogra | but i remember the desktop team had a bug about it early in jaunty ... though that was fixed for release | 08:53 |
| ogra | CK did spawn threads endlessly iirc | 08:53 |
| ali1234 | i saw that bug on launch pad, it seems to be a memory leak issue with lots of ssh connections. i only have one | 08:53 |
| ali1234 | strace just says: restart_syscall(<... resuming interrupted call ...> | 08:55 |
| ali1234 | then nothing | 08:55 |
| ogra | hmm, why dont we have a dove image today | 08:57 |
| ali1234 | it almost is a kernel issue since i'm using 2.6.25 and no particular config | 08:58 |
| ali1234 | *almost certainly | 08:58 |
| ogra | lool, Couldn't open .flint/dbw/postlist.baseA: Too many open files | 09:02 |
| ogra | Couldn't open .flint/dbw/postlist.baseB: Too many open files | 09:02 |
| ogra | ) | 09:02 |
| ogra | do you think it's worth trying to giv that back ? | 09:02 |
| ogra | (thats xapian-core) | 09:03 |
| ogra | seems like a buildd issue | 09:03 |
| lool | hmm | 09:13 |
| lool | Any other build like this? | 09:13 |
| ogra | nope | 09:13 |
| ogra | xapian seems to hammer the disk during its test phase | 09:14 |
| lool | I guess you could give it back | 09:14 |
| ogra | we have two idling buildds, i'll just try | 09:14 |
| lool | ogra: livefs failed to build | 09:14 |
| lool | http://people.canonical.com/~ubuntu-archive/livefs-build-logs/karmic/ubuntu-dove/latest/livecd-20090901-armel.out | 09:14 |
| lool | empathy: Depends: libmissioncontrol-client0 (>= 4.37) but it is not installable | 09:15 |
| ogra | ah, yeah, empathy | 09:15 |
| lool | evolution and others | 09:15 |
| lool | evolution: Depends: evolution-common (= 2.27.90-0ubuntu2) but it is not going to be installed | 09:15 |
| ogra | i just gave back evo, it always needs handholing | 09:15 |
| ogra | seb never waqits until the "all" packages are published | 09:15 |
| ogra | hmm, xapian has the same issue on ia64 | 09:16 |
| ogra | and on sparc | 09:16 |
| ogra | lool, i dont get why dove wouldnt use an older livefs as all other arches do though | 09:18 |
| * ogra pbuilds xapian-core locally | 09:19 | |
| lool | Oh that's unrelated, I actually broke the build but I fixed it now | 09:24 |
| lool | Well I think, I'm test building | 09:24 |
| lool | poumpoudoum | 09:28 |
| ogra | poumpoudoum ? | 09:30 |
| lool | lalala if you wish | 09:31 |
| lool | ok it built | 09:31 |
| lool | hmm that's bad | 09:31 |
| lool | /home/lool/cdimage/debian-cd/tools/pi-makelist-vfat: Couldn't list any drive | 09:31 |
| ogra | oh | 09:31 |
| ogra | i thought you were talking about xapian and wondered whn you secretly pushed that to the buildds :) | 09:32 |
| ogra | ETOOMANYTOPICSATONCE | 09:32 |
| lool | Oh | 09:35 |
| lool | We never actually cared to support partition=1 in pi-makelist-vfat | 09:35 |
| lool | only no partition or part 2 | 09:35 |
| ogra | which didnt fail since we never used partition 1 yet | 09:35 |
| lool | Hmm oddly it doesnt work with partition=1 either | 09:36 |
| lool | Ok found another bug in that script which went unnoticed | 09:37 |
| lool | Oh no it was just local to my edit, some typo during copy-paste caused a lowercase or something | 09:39 |
| lool | and it worked, cool | 09:40 |
| lool | all deployed, just waiting to confirm I can kick a rebuild | 09:40 |
| lool | Sure enough http://cdimage.ubuntu.com/ports/daily-live/20090831/karmic-desktop-armel+dove.list was empty | 09:42 |
| rabeeh | lool: which machine are you using for that build? | 09:42 |
| rabeeh | lool: are dove machines already part of the buildd cloud? | 09:43 |
| ogra | rabeeh, nope | 09:48 |
| lool | rabeeh: No, imx51 based | 09:48 |
| ogra | we hope to add dove soon though | 09:48 |
| lool | rabeeh: I dont think we can get z0 stable enough and we dont have enough yX | 09:48 |
| rabeeh | isn't that incremental work? meaning if you have 1 yx then you can add to buildd, and if you have 2 then you can add 2? | 09:49 |
| lool | My main worry is silent breakage: it might be ok if a buildd goes completely missing and has to be remote rebooted but it's not ok if it breaks in the middle of a build: it could either cause a subtle breakage to go unnoticed and if it actually fails the build we cant distinguish hardware errors from software ones which we need to fix :-/ | 09:50 |
| rabeeh | i mean you can start with what you have, and get more soon. | 09:50 |
| ogra | but we dont have a single one we can spare yet | 09:50 |
| lool | rabeeh: I think we could start like that, but we have no facility to schedule builds on this or that buildd | 09:50 |
| rabeeh | so, what is the yx board allocation o buildd/developer? | 09:53 |
| rabeeh | btw - is it possible to set a board remotely part of a buildd? | 09:54 |
| rabeeh | for example i have my own y0 board; that is free at nights and weekends; can i set it (behind a firewall) to be part of the buildd cloud? | 09:55 |
| rabeeh | (i know; this is intermediate solution until you get the amount of boards you have requested) | 09:55 |
| ogra | we have 7 armel buildds atm ... https://launchpad.net/builders | 09:56 |
| rabeeh | for example, you can never ssh to the board; but the board can poll and pull build requests from the web | 09:56 |
| ogra | and as you can see currently two are idle, one is in maintenance | 09:56 |
| ogra | having more doesnt really help, having faster ones will ... | 09:57 |
| ogra | which is why we look forward to add doves | 09:57 |
| rabeeh | hmm. why? | 09:57 |
| ogra | because one package is built on one buildd | 09:57 |
| ogra | if you take openoffice it takes about 36h to build | 09:58 |
| rabeeh | but they are idle :) | 09:58 |
| rabeeh | don't they have queues for karmic builds? | 09:58 |
| ogra | having it building in 24h would improve ... having one more buildd wouldnt help speeding it up | 09:58 |
| ogra | its not a cluster where adding more power would improve anything for the single build | 09:59 |
| ogra | adding more machines just lets the qeue get empty faster | 10:00 |
| ogra | butu the queue as you can see is empty most of the time ... it might indeed help at high times where you have tons and tons of uploads | 10:00 |
| ogra | the amount of 7 machines is quite ok ... replacing them incrementally with doves will help a lot but we currently need the few doves we have for development and QA of the dove image we build | 10:02 |
| rabeeh | which machines you have here are running on discovery 78100? | 10:02 |
| rabeeh | i recall canonical had few of those machines for jaunty armv5 armel distro | 10:03 |
| rabeeh | my point is can we use armv5+vfp machines for armv6+vfp? | 10:03 |
| ogra | right, but after the alpha5 release (thursday) we will default to only build for v6 | 10:04 |
| ogra | no, you cant use v5 machines for that | 10:04 |
| rabeeh | (implementing software instruction abort handlers for the armv6 part) | 10:04 |
| ogra | thats why we currently are stuck with imx51 machines | 10:04 |
| ogra | how stable would such a software layer be ... how much slowdown would you get through such an additional layer | 10:05 |
| rabeeh | well. it's hard to guess; but armv6 has big SIMD addition; which is never used in integer/floating based application | 10:06 |
| lool | sorry had an UPS delivery | 10:06 |
| rabeeh | it is used in packages like ffmpeg; and might only break if the debian/rules calls some test to use that | 10:06 |
| lool | and it's broken so I need to deal with it | 10:06 |
| rabeeh | lool: hope it's not Dove :) | 10:06 |
| lool | It's not :) | 10:06 |
| ogra | my assumption is that if you develop such a layer to run on v5 buildds you invest a lot of time to make sure its stable enough, do QA on it etc | 10:07 |
| ogra | and i bet once you are done the amopunt of y0 we want is available :) | 10:07 |
| ogra | so using imx51 until that point serves as well without risking stability | 10:08 |
| rabeeh | right. and i'm looking at the instruction set addition; and seems lots of instructions being added | 10:09 |
| ogra | right | 10:09 |
| rabeeh | will take lots of time to implement those exception handlers | 10:10 |
| rabeeh | ogra: what i can promise is that y1 boards will come with 1GB of DDR :) | 10:10 |
| ogra | effectively you would end up with something like qemu-arm inbetween the CPU and userspace | 10:10 |
| ogra | WOW ! | 10:10 |
| rabeeh | right | 10:10 |
| ogra | that will make a huge improvement ! | 10:10 |
| ogra | the diskspeed already is a huge improvement on the dove vs imx | 10:11 |
| ogra | adding more ram will make the builders fly :) | 10:11 |
| rabeeh | personally i think we should have buildd version of dove | 10:12 |
| rabeeh | overclocked and even more DDR | 10:12 |
| rabeeh | lunch time :) ttysw | 10:14 |
| ogra | :) | 10:14 |
| lool | rabeeh: It's common for packages to call binaries from others; not frequent but common enough that it needs to work well; for instances all GStreamer apps call the equivalent of gst-inspect on startup which will cause all plugins to be loaded | 10:37 |
| lool | Including ffmpeg | 10:37 |
| lool | (Now Gst is a special case because it actually traps sigill but still :) | 10:37 |
| rabeeh | ogra: back to the original question; is it possible that put my board part of the buildd cloud? (inside a firewall) | 11:08 |
| rabeeh | lool: got it. | 11:08 |
| ogra | rabeeh, nope, our IS team wouldnt allow that i guess | 11:15 |

| tlee | Has karmic's arm build system move to vfp yet? | 17:38 |
| ogra | after alpha5 we'll move immediately | 17:54 |
| tlee | Thanks Ogra. How many days (weeks) is that from now? Also how long you think it would take to rebuild all the packages? | 17:58 |
| ogra | alpha5 images will be released on thursday | 17:59 |
| ogra | (including a dove live image btw) | 17:59 |
| ogra | testing appreciated :) | 17:59 |
| ogra | no idea how long it will take to rebuild the whole archive ... i'd guess a week or two | 18:00 |
| ogra | lool, any idea ? | 18:00 |
| lool | ogra: we moved already | 18:04 |
| lool | to vfp | 18:04 |
| lool | tlee: we're using v6+vfp at the moment | 18:04 |
| ogra | oh ! | 18:04 |
| lool | We wont rebuild the archive | 18:04 |
| ogra | dont we do a complete rebuild anyway during the process ? | 18:05 |
| lool | What do you mean? | 18:05 |
| tlee | wow. | 18:05 |
| ogra | lool, on the std arches we usually do a complete archive rebuild before final | 18:06 |
| ogra | https://wiki.ubuntu.com/KarmicReleaseSchedule spt24th | 18:06 |
| ogra | *sept | 18:06 |
| ogra | and oct 15th | 18:06 |
| lool | ogra: That's out of archive | 18:09 |
| lool | We dont keep the results | 18:09 |
| ogra | oh, i thought we did | 18:09 |
| lool | ogra: So did you get like thousands of packages to download on the week before release? :) | 18:09 |
| ogra | why would i if the versions dont change | 18:10 |
| lool | ogra: Because the binaries arent identical | 18:14 |
| lool | ogra: It would be a terrible idea to have two .debs with different md5 and contents named the same thing and using the same version; we never do that | 18:14 |
| ogra | oh, indeed | 18:15 |
| lool | And it's also why we wont rebuild the whole archive just for armel | 18:15 |
| ogra | yeah, understood | 18:15 |
| ogra | thast a bit sad though | 18:15 |
| lool | Not too much | 18:16 |
| lool | But it's why the lack of buildd was such a big deal | 18:16 |
| ogra | indeed | 18:16 |
| lool | But given the number of uploads before release it's not that bad | 18:16 |
| ogra | true | 18:16 |
| ogra | problematic is that we wont see fallout caused by the setting for packages that werent uploaded | 18:16 |
| ogra | we'll likely hit the ftbfs'es for these in karmic+1 only | 18:17 |
| === bjf-afk is now known as bjf | ||
| tlee | Have any of you seen this "BUG: soft lockup - CPU#0 stuck for 61s!"? | 18:55 |
| ogra | nope, not on armel yet | 18:56 |
| tlee | Google it and it seems to happen a lot of times in kernel. | 18:56 |
| ogra | i have seen it on via eden | 18:56 |
| ogra | and other thin clients i worked with (geode etc) | 18:56 |
| tlee | orga: turn on nullmailer and see if you can see what I seen on karmic. | 18:56 |
| ogra | oh, wait, looking at my dmesg ... | 18:57 |
| ogra | http://paste.ubuntu.com/263307/ | 18:57 |
| tlee | I believe I have 400+ email Q to send out and nullmailer is trying to run every few minutes. Seems to trigger that erorrs for me. | 18:57 |
| ogra | it's currently doing a heavy duty build | 18:57 |
| tlee | on Karmic. Quite offer. | 18:58 |
| ogra | NCommander, http://paste.ubuntu.com/263307/ | 18:58 |
| tlee | On Jaunty, I see the bash has issue. | 18:58 |
| ogra | NCommander, watch your dmesg on the dove under load, appears to be a kernel bug | 18:58 |
| tlee | On Karmic, seems only the nullmailer. | 18:58 |
| ogra | well, i'm building a package here | 18:59 |
| ogra | and it seems to have been triggered by bash | 18:59 |
| tlee | Do you know any method to help track this bug down? | 19:01 |
| ogra | i pinged bjf in #ubuntu-kernel | 19:01 |
| bjf | orga, I can *sigh* here just as easily | 19:02 |
| ogra | heh | 19:03 |
| ogra | note that i use the -201 build still | 19:04 |
| bjf | ogra, oh! well that's obviously your problem :-) | 19:04 |
| ogra | not sure if 202 or 203 fix it, but i guess tlee runs something newer | 19:04 |
| ogra | i cant replace the kernel before webkit isnt finished, i need the log | 19:05 |
| ogra | and that might go on for the rest of the nigh ... | 19:05 |
| ogra | +t | 19:05 |
| bjf | ogra, I'll boot mine up and see what I see | 19:05 |
| ogra | i didnt see it before | 19:05 |
| ogra | seems to be load related | 19:05 |
| tlee | orga: what do you mean by 201, 202, 203? | 19:14 |
| ogra | the kernel builds | 19:15 |
| ogra | its the ABI version of the packaged kernels we use | 19:15 |
| bjf | tlee, you will see the version as 2.6.31-203.8, the 203 is the API versions | 19:16 |
| ogra | http://ports.ubuntu.com/pool/main/l/linux-mvl-dove/ | 19:16 |
| tlee | I am still back in 2.6.30. I built 2.6.31 last week, have not try it yet. | 19:16 |
| ogra | linux-image-2.6.31-203-dove_2.6.31-203.7_armel.deb is the current package | 19:17 |
| ogra | (i think there is one pending in the queue though) | 19:17 |
| bjf | ogra, yes there is one "in the queue", it has some of the latest mvl changes and we are building zImages instaed of uImages | 19:18 |
| ogra | yeah, i saw the thread on the ML | 19:18 |
| tlee | Ok, I will try to sync it up tomorrow. Have some demo to do today. Don't want to mess with the demo god for now. | 19:18 |
| ogra | heh | 19:19 |
| bjf | tlee, I hear that! | 19:19 |
| tlee | I am in trouble now. Lighting is stiking from above..... run ..... :-) | 19:20 |
| ogra | haha | 19:21 |
| NCommander | ogra, yeah, I've seen that. Thought it was an issue with the old kernel I was using | 19:30 |
| NCommander | It didn't reappear since I updated to a 202 kernel, although I haven't been using that as extensively | 19:30 |
| NCommander | actually | 19:31 |
| ogra | ok, i'll see what 203 does for me then | 19:31 |
| NCommander | er | 19:31 |
| NCommander | 203 | 19:31 |
| NCommander | er, 202 or 203 | 19:31 |
| NCommander | I used to get it trying to spin livecd-rootfs's | 19:31 |
| NCommander | then it went away when I updated the kernel | 19:31 |
| tlee | There is no uImage in the linux-image-2.6.31-203-dove_2.6.31-203.7_armel.deb. How do I make the uboot to load vmlinuz? | 22:45 |
