cooloneysmb: morning08:44
smbcooloney, good morning08:44
cooloneythese days i'm fighting with the building test on my imx6 board08:44
cooloneyi was asked to test building kdepim, gcc-4.6, chromium-browser, firefox and webkit08:45
apwcooloney, how is sbuild working out for you there08:45
cooloneyi only got kdepim build successfully, but other four packages fail for some reason.08:46
cooloneysometimes out-of-memory08:46
apwcooloney, but they build on your babbage ?08:46
apw(or whatever the current buildds are?)08:46
cooloneyoh, i never tried that on babbage before.08:46
apwbabbage may be the wrong name, i get very confused08:46
cooloneythey are supposed to be build without any error08:47
apwi probabally mean panda08:47
cooloneysince we build them on panda08:47
apwyou have a panda right?  so you could shift the sbuild containing disk over there and test 08:47
smbOK, if they build there with the same compiler it sounds a bit like some corruption going on on the other08:47
cooloneyand sometime the system will lockup without any output after a very long building time like 8 hours.08:47
apwto see if its your environment or the machine08:47
cooloneyapw: yeah, i'm trying to setup the environment with my PandaES. bs08:48
apwit might be good to literally take the same disk over there08:48
apwthen you'd know it wasn't that exact sbuild environment08:48
cooloneyright, i'm trying to do these on my PandaES. i tried another USB harddisk before, it looks like not very stable.08:51
apwcooloney, if they are not reliable over time, they are next to useless as that is exactly what we would want to do with them08:51
cooloneyi think i need a USB disk with external power supply. i just found one, and going to do that08:51
apwcooloney, ok08:51
cooloneyapw and smb, thanks for understanding. it is quite annoying about the build failure. and I will post the build logs after i tested it on my PandaES08:53
cooloneyapw: and for the lxc /root prefix issue. based on your idea, i think i can post a patch to LP for you guys discussion08:54
apwcooloney, ok sounds good, point me at it when it is there, i will forget otherwise08:55
smbcooloney, As apw said I think it is a good idea (if possible) to take the environment to the Panda and see what happens there. It would rule out this as a source of error. And yes, if you have something, post it 08:56
smbcooloney, I assume it is a change to the lxc setup?08:57
cooloneysmb: yeah, that's what i'm going to do. i got an SATA-TO-USB cable and an external SATA HD power supply now08:57
smbppisati, Try the getabis posted and let us know how that works :)08:58
ppisatismb: i'm finishing another kernel than i'll test ot08:59
ppisatiit08:59
smbapw, Yes, some message/warning would do ok. Hopefully you never place a package of the exact name there, but anyway.08:59
apwsmb, indeed but if you do it'll be a big confusing supprise that you cannot get it to work, then i ask you to test and it works and i pull all my (remaining) hair out09:00
smbapw, No we would not want you to do that... :)09:01
apwsmb, exactly, who would look like bill the cat then09:01
smbbill the cat himself?09:02
cooloneyapw: i posted the patch in bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/95935209:27
ubot2`Ubuntu bug 959352 in lxc "Ephemeral containers have "/rootfs" prefix in /proc/self/maps entries" [High,Confirmed]09:27
apwcooloney, thanks09:29
apwcooloney, i have also made comment that as only the rootfs part of the name leaks into the container, there may be something we can do with the way the unions are placed to get rid of it should they really not be able to cope with the prefix09:35
apwperhaps placing two unions instead of one or something09:35
dileks+        # echo "rming rootfs softlink for overlayfs" >&209:38
dileksRemoving/Deleting09:38
cooloneydileks: that's is just a comment, i followed others 09:38
dileksand I thought its rming's rootfs09:39
cooloneyapw: hmmm, i don't fully understand here. 09:39
cooloneyapw: do you mean we move the unions directory to some other place instead of "rootfs"?09:40
apwcooloney, me either i am just suggesting they may be able to play with mounting differnetly09:41
apwi have not looked to see how its mounted09:41

jibeltodays quantal server with LVM fails to reboot after installation11:41
jibelbug 103661211:41
ubot2`Launchpad bug 1036612 in linux "Quantal Server failed to install with LVM: VFS: Cannot open root device "mapper/ubuntu-root" or unknown-block(0,0): error -6" [Undecided,New] https://launchpad.net/bugs/103661211:41
smbjibel, Repeatable or maybe just some failure with the initrd (which it quite often is)12:01
jibelsmb, repeatable, all the automated tests that use LVM failed and reproduced manually12:02
jibelsmb, alternate, which also runs a test with LVM but doesn't use a squashfs for installation passes. And it uses the same kernel12:03
smbOk, hm. mapper/ubuntu-root... would be good to know what grub.cfg looks like and what the vg / lv is named, but I assume it uses ubuntu as hostname, too...12:04
smbI'll try to reproduce it here...12:05
henrixapw: are you aware of any network changes on tangerine or gomeisa?12:08
henrixapw: i'm not able to run rmadison anymore12:09
henrixapw: for ex., 'rmadison --architecture=source linux' seems to hang forever12:09
henrixwell... no forever. it eventually exit with a 'couldn't connect to host' error12:10
smbhenrix, firewall? did that work before?12:10
henrixsmb: yes, it did work before12:11
henrixsmb: the makefile for the meta packages actually use rmadison12:11
henrixsmb: that's how i found something's changed12:11
smbhenrix, Ok, so that really sounds like something changed in between12:12
smb(not on the hosts)12:12
henrixyep12:12
ppisatismb: it works12:17
* smb assumes it is the getabis script and not the rmadison call12:17
ppisatismb: yep, getabi12:18
smbppisati, Cool, then you can ack it12:18
* smb closes both eyes on tangerines dmesg...12:19
smbhm gomeisa as well...12:20
henrixouch! :)12:20
smbapw, non-accessible hardlink creation was attempted by: git12:20
henrixi've never seen this error before, but it looks like its yama related12:26
henrixsysctl kernel.yama.protected_nonaccess_hardlinks12:26
smbhenrix, Yes I think it is some effect of hardening12:28
smbhenrix, It might be we need to talk to sforshee ... ;)12:38
smb... and Joe and Colin...12:39
smb... he and I have to talk to me as well...12:41
henrixheh12:41
apwsmb, so when is that happening?  when pusing or locally?12:42
smbapw, Cannot say, its just entries that happen at some point12:42
apwsmb, not that it matters probabally ... as git will fall back to copying12:42
smbMust be something I cannot write to... hm, maybe --reference /usr3/...12:43
smbapw, Yeah, both are on the same disk... I guess that is what happens 12:44
apwyeah makes sense.  and git is hiding it from you probabally12:45
apwas it probally just does ln, and if that fails its copies12:45
apwassuming ln failure will be cross disk12:45
smbsounds reasonable... Just trying it, so my id should produce a new msg12:45
smbit did12:45
smbapw, And no error from git. Only scary thing is a double entry in alternates (which likely does not matter either)12:47
apwoh that is odd12:49
smbbut I suspect it might be completely unrelated12:50
* smb wonders whether hardlink protection might go a step too far, though12:51
apwit is doing what is intended, it is preventing you linking to things you cannot write to12:52
apwso that you cannot drop links to things you cannot modify in random places12:52
apwto be overwritten by accident12:52
smbhm, thought git would create only readable objects...12:52
smbthough at some point they probably are writeable, otherwise it should not be possible to create them...12:53
apwi may be able to write to the directory but not link the files as they are yours12:58
smbapw, Well I guess, given that my objects appear to be writeable to me (on gomeisa, my local repo objects seem to be read-only) that hardlink failure is correct13:05
henrixapw: what about the rmadison failure i referred above? any idea?13:06
apwhenrix, seems to work for me here now13:07
apwrmadison -a source linux13:07
henrixhmm... i'm unable to run it on tangerine or gomeisa, but it runs locally on my laptop13:07
smbAnd it still does not on gomeisa for me13:08
smbI asked on #is but got no answer yet13:08
henrixon gomeisa i get an error; on tangerine it seems to hang forever13:08

hggdhsforshee: just a Q -- my touchpad when south with the new kernel on quantal, is it still an option to try your dkms?15:10
sforsheehggdh, that dkms package was only for testing. All the changes should be in quantal, so if it worked with the dkms package and doesn't work with quantal file a bug and assign it to me.15:15
hggdhsforshee: will do, thanks.15:15
sforsheemjg59, would you be agreeable to picking up the gmux switcheroo changes now, before the graphics driver issues are sorted out? That will at least get the mux state restored correctly after s3.15:19
mjg59sforshee: Yeah, I think so15:20
mjg59sforshee: It shouldn't break any existing config15:20
sforsheemjg59, no it shouldn't. I'll rebase on top of your patches for the retina then and send the patches later today.15:20
mjg59sforshee: Brilliant, thanks15:21
