| elfy | apw: currently I am at https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1371651/comments/58 | 13:35 |
| ubot5 | Ubuntu bug 1371651 in plymouth (Ubuntu) "Daily does not boot into graphical interface after installation" [Critical,Fix released] | 13:35 |
| apw | elfy, ok then this is something new, as the segv was the clear trigger for the problem i fixed | 13:36 |
| elfy | ok | 13:36 |
| apw | can you file a new bug against, erm lightdm to start with and let us get the bits for your issue together | 13:38 |
| elfy | apw was just going to ask that :) | 13:38 |
| elfy | apw: do you want me to do the bug before I've started lightdm ? | 13:39 |
| apw | elfy, sounds best yes | 13:41 |
| apw | elfy, also when there what does "cat /proc/fb" say | 13:43 |
| elfy | once booted or before? | 13:44 |
| apw | either i think | 13:44 |
| elfy | ok - well once lightdm starts 0 VESA VGA | 13:45 |
| elfy | I'll check the other in a minute | 13:45 |
| elfy | apw: bug 1375805 | 13:48 |
| ubot5 | bug 1375805 in lightdm (Ubuntu) "Lightdm fails to start in VirtualBox " [Undecided,New] https://launchpad.net/bugs/1375805 | 13:48 |
| apw | elfy, ok can you grab a dmesg from the machine before lightdm starts onto the bug as well | 13:52 |
| elfy | do my best | 13:52 |
| apw | jodh, is there a way to say "status all" to get all jobs ? | 13:55 |
| elfy | apw: done | 13:55 |
| apw | elfy, and an "initctl list" | 13:56 |
| elfy | yep - anything else while I'm there? | 13:57 |
| apw | elfy, not sure, /me is flying blind currently | 13:57 |
| elfy | heh | 13:57 |
| apw | elfy, i wonder if this reproduces with --verbose on the end of the kernel command line | 13:58 |
| elfy | apw: initctl added - I'll try with --verbose | 14:00 |
| elfy | apw: just goes straight to tty1 without even trying tty7 | 14:02 |
| apw | elfy, i hate debugging upstart interactions | 14:04 |
| elfy | :) | 14:04 |
| elfy | apw: ok - so now when I start lightdm (with --verbose and it not even trying tty7) it starts into a sensible sized vbox instance instead of 64x480 | 14:06 |
| apw | elfy, erm | 14:06 |
| elfy | probably no help - but I'm trying to just give you what I see here | 14:06 |
| apw | elfy, ok so i guess i need the syslog bits for init: at least from the --verbose boot you did, so i can compare them to mine; which obviously works | 14:13 |
| elfy | so verbose and do a new syslog? | 14:13 |
| apw | yeah the --verbose bits get dumped into syslog, well they did on mine | 14:16 |
| elfy | apw: added | 14:17 |
| apw | elfy, what video options did you select for this VM btw ? | 14:17 |
| elfy | I don't tend to fiddle much - 3d enabled and 128Mb | 14:18 |
| apw | ok so you are different to me, i'll try those | 14:19 |
| elfy | apw: ok - what do you have - I can try with yours | 14:19 |
| apw | whatever the defaults are, something like 12M and none of the tickies on | 14:20 |
| elfy | ok | 14:20 |
| apw | yeah 12m | 14:20 |
| apw | nope that works for me as well (128m and 3d( | 14:21 |
| apw | elfy, what release is your host | 14:21 |
| elfy | utopic | 14:22 |
| apw | this is a trusty host | 14:22 |
| elfy | ok - I'll reboot into trusty and see what occurs there - biab | 14:22 |
| elfy | give me a while to install the vm - biab | 14:23 |
| elfy | and whatever updates I've got pending - don't boot it often :) | 14:23 |

| jsalisbury | ** Ubuntu Kernel Team Meeting - Today @ 17:00 UTC - #ubuntu-meeting | 14:51 |
| jsalisbury | ** | 14:51 |
| elfy | apw: ok - so in trusty with vbox v 4.3.16-95972 I get exactly the same fail | 14:53 |
| apw | elfy, ack thanks for testing that, i am sure it was a pita | 14:53 |
| elfy | fairly :) | 14:53 |
| elfy | not sure it puts us anywhere further forward though | 14:54 |
| apw | elfy, ok i think i know approximatly what is happening; you are not getting a graphics card notification | 15:17 |
| apw | elfy, which for the moment i am going to put down to a race | 15:17 |
| apw | elfy, which means you should hit the fallback, and it seems that that is busted in utopic | 15:17 |
| apw | elfy, someone has tried to fix it, and failed badly | 15:17 |
| * apw will poke it and get back to you | 15:18 | |
| apw | elfy, actually could you take the contents of http://paste.ubuntu.com/8466613/ as /etc/init/udev-fallback-graphics.conf | 15:19 |
| apw | elfy, and let me know if that at least gets you lightdm | 15:19 |
| backjlack | Hello! | 15:32 |
| backjlack | I'm seeing a major problem on Ubuntu 12.04 with trusty-lts: https://i.imgur.com/EXQm49N.png | 15:32 |
| backjlack | 1 GB of RAM is used by upstart-udev-bridge and 240 MB of RAM is used by "init" | 15:33 |
| backjlack | I was able to run into this problem by running ~200,000 Docker containers. | 15:33 |
| apw | jodh, ^^ that sounds like a memory lieak in upstart-udev-bridge or something | 15:38 |
| elfy | apw: I succeeded in killing the existing vm - reinstalling it now - will do that ^^ asap | 15:39 |
| apw | backjlack, is that in one instance of upstart-udev-bridge ? | 15:39 |
| backjlack | apw: yes | 15:39 |
| backjlack | apw: headless ubuntu server with trusty lts kernel, fully updated | 15:40 |
| apw | backjlack, ok that does sound like a memory leak or similar in upstart-udev-bridge ... could you file a bug on that | 15:41 |
| backjlack | apw: Ok, what should I file the bug against? | 15:41 |
| apw | backjlack, ubuntu-bug upstart | 15:42 |
| jodh | backjlack: as apw says, please raise a bug so we can investigate. | 15:43 |
| hallyn | "skipabi=tue" well that ain't gonna fly | 15:43 |
| apw | hallyn, :) | 15:44 |
| elfy | apw: posted confirmation to bug - that .conf works here | 15:48 |
| rtg | hallyn, try skipabi=weds | 15:49 |
| apw | elfy, thanks ... thats at least an easy fix | 15:49 |
| apw | rtg, :) | 15:49 |
| elfy | :) | 15:49 |
| apw | elfy, now to go and beat on the person who removed it :) | 15:51 |
| elfy | heh | 15:51 |
| elfy | I shall toddle of into other less uncharted channels for me now - I'm about if needed :) | 15:52 |
| elfy | apw: thanks for your help | 15:52 |
| apw | elfy, heh yeah thanks to you for your quick testing, that got us there | 15:52 |
| elfy | welcome as always | 15:52 |
| elfy | cheers :) | 15:52 |
| hallyn | rtg: why not just shoot for the moon, fri no doubt will have the happiest results. unless we're in one of those countries where kids get a hlaf day every wed | 15:54 |

| ubot5 | Ubuntu bug 1198180 in upstart (Ubuntu) "possible leak in upstart 1.5" [Medium,Confirmed] | 15:57 |
| backjlack | Should I also investigate 14.04 to make sure it doesn't have the exact same problem? | 15:59 |
| apw | backjlack, that owuld be interesting to know for sure | 16:00 |
| backjlack | Ok, that should take only a few minutes to confirm. | 16:04 |
| apw | smb, shortly there should be new udev binaries for this fallback thing in https://launchpad.net/~apw/+archive/ubuntu/lp1375805 ... i'll be interested to know if they fix your binary-drivers not giving you lightdm issue too | 16:23 |
| smb | apw, okidok | 16:23 |
| apw | smb, of cour the build estimates are just static in time | 16:36 |
| smb | It will be build by 6pm (though we do not say which day)? | 16:37 |
| rtg | apw, can you comment on this ? (should be simple) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1121699/comments/9 | 16:38 |
| ubot5 | Ubuntu bug 1121699 in linux (Ubuntu Raring) "aufs CONFIG_AUFS_EXPORT build option should be enabled" [Medium,Fix released] | 16:38 |
| apw | rtg, ack, and i still have that perl thing to look at now i have "fixed" this vbox "kernel" issue | 16:40 |
| rtg | apw, the hyper-v dudes are complaining about crash dump still, but it appears to be a matter of a larger reservation. | 16:41 |
| apw | smb, ^ didn't we talk about using a smaller initrd for those? ==neeed or something ? | 16:42 |
| apw | smb, as i suspect we are holding like half the ram in these instances | 16:42 |
| smb | apw, Though the size was also just made bigger... | 16:42 |
| apw | smb, "just" == ? | 16:43 |
| smb | apw, would have to install it again.... though maybe arges remembers it from his head (having to use it) | 16:44 |
| apw | smb, ok trying to work out if the hyper-v folk tested before or after "just" | 16:44 |
| smb | apw, iirc it would be = something (something maybe 256M | 16:45 |
| apw | yeah i assumed they changed it from 128 to 256 or somethign | 16:45 |
| apw | but more it is the when of it ... | 16:45 |
| apw | though how big is am m1.small, that isn't going to leave anything for the actual instance :) | 16:45 |
| smb | Somehwen between P and T but I know that is vaque | 16:46 |

| smb | smalles you get would be micros (~ 600M). I think m1.small is 3.5G already | 16:46 |
| smb | apw, Hrm... and m1 seems to be "old fashion" anyway http://aws.amazon.com/de/ec2/instance-types/ | 16:47 |
| smb | ok... m1.small down there , so 1.7 G | 16:48 |
| apw | smb, that feels like they have gotten a whole heap bigger than i remember | 16:50 |
| smb | apw, Yeah. m1.small is now considered something similar than micro... at least one could think that | 16:51 |
| backjlack | Is there any way at all to get a libc with dbgsym? | 16:51 |
| arges | smb: what happened? | 16:55 |
| smb | arges, Nothing immediate. Just apw was asking about what mem size we nowadays use for kcrash | 16:56 |
| arges | smb: i think i had a bug to bump it | 16:57 |
| arges | it would be nice if we made it have an auto parameter | 16:57 |
| smb | Yeah, at least for the small ram size it would not work in the past. So I think we just went to something for all... just cannot remember what value | 16:58 |
| arges | 384M | 16:58 |
| smb | oh ok. quite a bit for small systems but we probably not expect those being around that much | 16:59 |
| arges | smb: we can specify ranges too | 16:59 |
| smb | Yeah, I know. Problem was the initrd by default being too big | 17:00 |

| jdesfossez | Hi, I'm trying to detect if a target kernel is a ubuntu kernel | 17:21 |
| jdesfossez | I noticed the new UTS_UBUNTU_RELEASE_ABI symbol which is great | 17:21 |
| jdesfossez | but I need to include generated/utsrelease.h to have it | 17:22 |
| jdesfossez | which might not exist | 17:22 |
| apw | why might it not exist | 17:22 |
| jdesfossez | I don't see it on a vanilla kernel | 17:22 |
| jdesfossez | hum actually I see it, but I'm wondering if this file always exists | 17:25 |
| apw | i believe that is a purfectly standard header indeed, i am not sure you need to nclude generated though | 17:31 |
| apw | isn't there a real wrapper for that ? | 17:31 |
| smb | include/linux/vermagic.h:#include <generated/utsrelease.h> | 17:35 |
| jdesfossez | ah great | 17:35 |
