| Kano | hi, do you want to build a 3.14 kernel soon? | 11:29 |
|---|---|---|
| infinity | Kano: Like this one? http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-trusty/ | 11:30 |
| Kano | well with aufs | 11:30 |
| Kano | not mainline | 11:30 |
| infinity | Then you want http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=shortlog;h=refs/heads/unstable | 11:31 |
| Kano | i know, but its not tagged | 11:31 |
| Kano | i currently build that | 11:31 |
| Kano | i already updated ndiswrapper, fglrx, nvidia with rc8, the patches are simple, ndiswrapper you can get from debian | 11:32 |
| smb | apw, So my ppa now contains the updated xen package. I think I will have to change the binary package that I use to add the grub config from utils-common to hypervisor since that at least triggers an update-grub run. | 12:30 |

| apw | smb, sounds good, do you want me to test that or wait on this binary package move? | 13:09 |
| smb | apw, Hm, maybe its better to wait for the move. | 13:14 |
| apw | smb, ack | 13:19 |

| smoser | anyone interested in looking at this: | 14:05 |
| smoser | http://paste.ubuntu.com/7184918/ | 14:05 |
| smoser | should i file a bug? | 14:05 |
| smoser | note the old kernel version | 14:06 |
| rtg | smoser, wow, thats pretty old. can you repro it with the current kernel ? | 14:10 |
| smoser | rtg, this is the only time i've ever seen that. | 14:10 |
| smoser | so, probably not. | 14:10 |
| smoser | but that doesn't mean anything :) | 14:11 |
| rtg | well, probably not much we can do about it. | 14:11 |
| smoser | mainly i just posted to see if it showed an obvious error. | 14:11 |
| rtg | its not one I recognize | 14:11 |

| apw | rtg, have pushed an update to master-next | 15:07 |
| rtg | apw, ack | 15:09 |
| smb | apw, Ok, ppa now has the more recent test version of xen | 15:11 |
| apw | smb, thanks | 15:11 |
| apw | smb, what do i undo in my setup to be "normal" for it to work | 15:11 |
| apw | smb, as i currently have it mangled to make it use xen right ? | 15:11 |
| smb | apw, If you have set some GRUB_DEFAULT != 0 and not booted manually into xen you could set that back to 0 | 15:12 |
| apw | smb, yeah that ... | 15:12 |
| smb | apw, Bah, of course right after saying that, there is a "bug" in the message... its /etc/default/grub.d/xen.cfg to look into | 15:15 |
| rtg | apw, pushed AA sync | 15:50 |
| apw | rtg, ack | 15:52 |
| rtg | apw, I'm gonna jigger HEAD to add a bug number (bug #1298611) | 15:54 |
| ubot2 | Launchpad bug 1298611 in libvirt (Ubuntu) "[FFe] apparmor signal and ptrace mediation" [High,Triaged] https://launchpad.net/bugs/1298611 | 15:54 |
| apw | smb, those see to work mostly as i would expect thanks, modulo that error you self spotted | 15:54 |
| apw | rtg, ack | 15:54 |
| jdstrand | apw, rtg: did the release team ack it? | 15:55 |
| === gerald is now known as Guest30600 | ||
| rtg | jdstrand, they don't get to ack kernel patches | 15:55 |
| smb | apw, Cool, I already updated the local source to keep me forgetting | 15:55 |
| smb | from | 15:55 |
| jdstrand | rtg: not even for feature? | 15:55 |
| jdstrand | cause, infinity seemed to indicate they would | 15:55 |
| rtg | jdstrand, besides, kernel freeze is not until Apr 3 | 15:56 |
| jdstrand | (and I've kept infinity in the loop all along) | 15:56 |
| jdstrand | well, I don't mean to disrupt the process. just trying to do it by the book :) | 15:56 |
| rtg | jdstrand, according to jjohansen these patches should be backward compatible with Precise user space. | 15:56 |
| jdstrand | they are | 15:56 |
| rtg | ok, then I'm fine with them | 15:57 |
| jdstrand | extensive testing was performed by him and me for that configuration (and others). this is detailed in the bug | 15:57 |
| jdstrand | wfm | 15:57 |
| rtg | jdstrand, yup, I had a pretty good conversation with him about it last friday | 15:57 |
| jdstrand | ack. the testing continued over the weekend with the code in the pull request | 15:59 |
| apw | rtg, i think the only thing we care is if they are going to reject the whole feature us carrying the patches makes no sense | 16:02 |
| rtg | apw, perhaps, but it does keep us closer to upstream, and should be benign for Precise user space. | 16:03 |
| rtg | dannf, have you booted 3.13.0-20.42 on an x-gene SOC ? | 16:06 |
| dannf | rtg: we booted the first -20, dont' remember the version | 16:06 |
| rtg | I made a bunch of config changes, some of which may have affected arm64 | 16:06 |
| rtg | dannf, -20.41 should have been sufficient. -20.42 was just packaging | 16:07 |
| dannf | rtg: ok. i'll double check just to be sure | 16:07 |
| rtg | dannf, thanks | 16:08 |
| rtg | ppisati, you should do the same for your Trusy armhf platforms | 16:08 |
| * ppisati reads the backlog | 16:09 | |
| rtg | ppisati, just make sure the latest Trusty kernel works | 16:09 |
| ppisati | rtg: i'll do | 16:10 |
| apw | rtg, aa> fair enough i guess, as we should have the older support still and the kernel bits should understand the lack of userspace features | 16:10 |
| apw | rtg, pushed a could of "shhhh" patches | 16:11 |
| ppisati | rtg: doing another upload before freeze? | 16:11 |
| rtg | ppisati, yup | 16:11 |
| ppisati | rtg: i would like to squeeze a ptch in, if i can make upstream ack a problem i'm seeing | 16:12 |
| rtg | apw, where did your "shhhh" patches go ? | 16:12 |
| ppisati | rtg: ping me before the deadline | 16:12 |
| apw | rtg, look to be there for me | 16:12 |
| rtg | ppisati, wednesday is the last possible | 16:12 |
| rtg | day | 16:12 |
| ppisati | rtg: ack | 16:12 |
| rtg | apw, must have been a race. got 'em now | 16:13 |
| rtg | apw, I'm wondering if we shouldn't set CONFIG_ZSWAP=n ? Especially for an LTS kernel. This feature is still considered experimental by upstream. | 16:18 |
| rtg | perhaps turn it back on for 14.10 | 16:20 |
| apw | rtg, as long as that isn't the one we use for low memory systems in the installer | 16:21 |
| apw | rtg, which i think is ZRAM | 16:21 |
| apw | rtg, so the other question is when is it used, always if it is on, on | 16:21 |
| apw | or does one have to trigger its use somehow | 16:21 |
| rtg | apw, ZSWAP always on as far as I can tell | 16:22 |
| rtg | is always* | 16:22 |
| apw | rtg, hurm, difficult given we ave been using it such a lot then, but i can see turning it off ought to be safer | 16:25 |
| rtg | apw, well, we do have a lot of bug reports about suspend/resume, and a number of other random page faults. seems like a possiblity (though I have _no_ hard information). | 16:25 |
| apw | rtg, then wack it | 16:26 |
| rtg | just going by the help text for the feature.... | 16:26 |

| vlad_starkov | QUESTION: Is it possible to disable udev on boot? (Ubuntu 14.04 Server 64bit) | 17:40 |
| * antarus blinks | 17:41 | |
| antarus | in Ubuntu? why would you want to do that? | 17:41 |
| vlad_starkov | antarus: My system does not boot even with Live USB. It hangs with CPU soft lockup errors | 17:42 |
| vlad_starkov | antarus: I think the cause of this is in kernel modules load sequence | 17:42 |
| antarus | hrm interesting | 17:45 |
| === hatch__ is now known as hatch | ||
| vlad_starkov | antarus: if you like I can pastebin console logs at boot | 17:46 |
| antarus | sorry, I probably can't help you | 17:47 |
| * antarus mostly lurks here | 17:47 | |
| vlad_starkov | antarus: OK | 17:49 |
| antarus | I was mostly curious why you wanted udev off. The best idea I can think of is to somehow guess which module is causing hte problem and blacklist it somehow? | 17:50 |
| antarus | not sure what the kernel command line arugments are for that | 17:50 |
| vlad_starkov | antarus: this is whta I'm trying to do | 17:51 |
| TJ- | vlad_starkov: I'm with you here, too | 17:52 |
| vlad_starkov | TJ-: Oh nice | 17:52 |
| vlad_starkov | TJ-: so, I think this is the last attempt to deal with my server | 17:53 |
| vlad_starkov | TJ-: for now I disabled SATA and PATA. Trying to boot from USB. The same result :) | 17:53 |
| TJ- | vlad_starkov: Did you get the memoserv note I left you Friday night? | 17:53 |
| vlad_starkov | TJ-: Mmm I think I'm not | 17:54 |
| TJ- | vlad_starkov: Check... I suspect it'll address issue | 17:54 |
| vlad_starkov | TJ-: never did it before, could you guide me how to check memo | 17:54 |
| TJ- | vlad_starkov: "/msg memoserv help" | 17:55 |
| TJ- | vlad_starkov: The gist was, kernel option "elevator=deadline" ought to fix it | 17:55 |
| vlad_starkov | elevator=deadline | 17:56 |
| vlad_starkov | yep, just read it in memos) | 17:56 |
| vlad_starkov | TJ-: let me try | 17:56 |
| TJ- | vlad_starkov: I had to think hard to remember it! | 17:56 |
| TJ- | vlad_starkov: Shall we switch back to #ubuntu-server, to avoid messing up the kernel team's history ? | 17:56 |
| vlad_starkov | TJ-: sure! | 17:57 |
| dannf | rtg: oh yeah, works fine | 18:55 |

| darklight_ | the latest kernel kinda broke the intel driver | 23:05 |

| darklight_ | happens with i915 too | 23:05 |

| RAOF | darklight_: What mesa are you running against? | 23:16 |
| darklight_ | RAOF: 10.1.0-1 stock 14.04 atm | 23:17 |
| darklight_ | I've seen a bug report for kwin online and here I have another application failing related to node-webkit | 23:18 |
| RAOF | Huh. I thought that bug was introduced in a more recent mesa. | 23:18 |
| RAOF | I've seen tjaalton talking about that with upstream. | 23:18 |
| * RAOF sends out the Bat Signal | 23:18 | |
| darklight_ | I tried with 3.19 and at least for my testcase things work fine | 23:19 |
| darklight_ | 3.20 breaks it | 23:19 |
| darklight_ | for reference it's the popcorn-app, it's not in the repository, but I think anything related to node-webkit should show the same isse | 23:19 |
| darklight_ | RAOF: I'm off to bed, if you need me to test something /msg me | 23:21 |
