JamesPageQuestion: can someone confirm that the ibmasm module is *not* supported on powerpc architecture?  I believe it relies on x86 but wanted to check. Thanks :-)11:12
apw        depends on X86 && PCI && INPUT && EXPERIMENTAL11:14
apwJamesPage, ^^11:14
JamesPageThought that was the case; thankyou!11:15

ubot2Launchpad bug 574910 in linux-meta (Ubuntu) (and 4 other projects) "High load averages on Lucid while idling (affects: 35) (dups: 3) (heat: 230)" [Undecided,Invalid]14:29
smbsmoser, jj-afk has been fixing up the rebase and bjf[afk] will proceed to prepare the upload as soon as he is not afk anymore14:30
smoserthanks. 14:30
ogasawaraapw: awesome, thanks14:37
tgardnerogasawara, you're up early.14:39
tgardnerogasawara, do you have a FFE for module-init-tools ?14:39
ogasawaratgardner: so I've got the diff which I was going to ask you to give a quick once over14:40
* smb wonders whether the question is related to the statement...14:40
ogasawaratgardner: I'm not sure what additional process is involved beyond that in order to upload14:41
tgardnersmb, its tangentially related14:41
tgardnerogasawara, just robbiew's signoff in the bug. the archive admins'll hold it until then14:41
ogasawaratgardner: ack, I'll update the bug with sabdfl's test results and then have robbiew review14:42
tgardnerogasawara, shall I upload the bits from your PPA ?14:43
ogasawaratgardner: yep that'd work, just munge the version to be proper (ie not have the ~lp630748)14:43
tgardnerogasawara, ack14:44

tgardnerogasawara, hmm, wth is your launchpad PPA address? I seem to be challenged this morning.14:45
ogasawaratgardner: https://launchpad.net/~leannogasawara/+archive/ppa/14:46
tgardnernm, leannogasawara14:46
tgardnerogasawara, I think the PPA filter should default to 'Any series'. It always throws me for a loop when I don't immediately see a package that I _know_ should be there.14:48
apwtgardner, that is a most irritating feature14:49
tgardnerapw, I think thats why I got confused about -meta in teh kernel-ppa last night.14:49
tgardnernow that I think about it14:50
apwwell we were missing some for lucid as well14:50
apwbut +packages is the only page i understand these days14:50
ogasawaratgardner: have robbiew's Ack for upload in the bug now14:58
tgardnerogasawara, too late, already uploaded :)14:58

tseliotsmb: do you know what can be causing this? https://pastebin.canonical.com/38003/17:36
tseliotsmb: in a 32bit chroot on a 64bit host17:37
tseliotadding -m32 to CFLAGS and -melf_i386 to LDFLAGS doesn't seem to solve the problem17:37
smbtseliot, I trie to find what the issue is you might mean17:38
smbtseliot, and the chroot is started with linux32, so uname -m shows i686?17:39
tseliotsmb: I'm building a kernel module with dkms in a chroot that is not using linux3217:39
tseliotand the arch is shown as x86_6417:39
smbthat may be the problem17:40
tseliotsmb: do you know of any workarounds apart from using linux-32?17:40
smbwhy would you not do that17:40
apwtseliot, why would you do that?17:41
smbyou want a 32bit build in a chroot17:41
tseliotright17:41
smbso you need to start it or have it configured to start with linux32 compat mode17:41
tseliotit's our build system, I guess17:41
smbtseliot, I am not really sure I know what you try to do and maybe I do not want to know either17:42
apwcirtainly you are asking for a world of pain running a 32bit userspace without the compat17:42
smbI see 2.6.24 mixed with 2.6.36 versions17:42
tseliotyes, 2.6.24 is the host17:42
apwso that is to be expected as the real kernel is .2417:42
tseliot2.6.32-22 is the guest and 2.6.36 is just part of the path (not an actual kernel)17:43
apwso the only thing wrong seems to be the missing linux32, but why is that missing?17:43
tseliotthat's a good question17:43
smbI am actually even surprised that running a 2..6.32 chroot on a 2.6.24 host works... but ok17:44
tseliotyes, I do it all the time17:44
tseliotbut I don't build kernel modules in a chroot17:44
apwit probabally has to work else the buildds wouldn't work17:44
tseliotI'm asked that hoping to get an answer (as I don't work on buildds)17:45
apwbut ... i would concentrate on the linux32 missing, i don't see how that can be right17:45
smbtseliot, Or could it be that .o files remain locally after a 64bit buildß17:46
tseliotsmb: and how would you deal with that17:47
tseliot?17:47
smbtseliot, The problem is that I do not know how you get to the place you got. Is the directory cleaned, or is it like our builders which start from a clean point17:48
tseliotsmb: I think it starts from /var/lib/dkms/compat-wireless-ath9k-htc/source (which is clean) and copies that to /var/lib/dkms/compat-wireless-ath9k-htc/build and starts the build17:49
apwtseliot, perhaps you could get us the schroot/dchroot configuration file for the chroot to look at17:50
apwtseliot, as smb said, the other option is the directory was not clean from a 64 bit build (the build directory) and it could have looked it cause the files its moaning about are .tmp.xxx files which you'd not see by default17:53
tseliotapw: sure, let me see where that file is17:54
tseliotapw: I don't think I have a configuration file with the "arch"17:58
smbtseliot, Is that a machine where you can login and start the chroot yourself?17:59
smbtseliot, Then what type schroot or dcroot17:59
smbdepending on that its either /etc/schroot/schroot.conf or /etc/schroot/schroot.d/something or /etc/dchroot/dchroot.conf or so18:00
smbcannot remember the full detals18:00
tseliotapw, smb: no, I don't have access to that machine, however I can reproduce the problem in my pbuilder chroot18:00
smbtseliot, You mean you *have* reproduced it or you *may* if we want to?18:01
apwtseliot, so you have also hit this problem in a pbuilder env ?18:01
tseliotsmb: I have reproduced the problem here in pbuilder and I'm currently inside the chroot18:01
tseliotapw: yep18:02
smbSo ok, and inside the 32bit chroot you run uname -m and get x86_86, right?18:03
tseliotsmb: x86_6418:03
tseliotso, yes18:04
apwtseliot, ok even on my natty kernel i get i686 in  my 32bit chroots18:09
jjohansenapw: is the overlayfs you mentioned fuse based, or is there another one?18:09
apwthere much be something wrong with the chroot setup18:09
apwjjohansen, no that is kernel based18:09
apw(the one i mentioned is)18:09
jjohansenapw: okay, when I looked all I found was miklos and neils fuse one18:10
apwjjohansen, look for overlayfs and hybrid union mount in the lkml archives18:10
apwtseliot, so we need to see the command line and configuration for the chroot you are using18:12
apwtseliot, as all of ours in all combinations say i686 and yours does not18:12
tseliotapw: ok, how do I do that? Shall I tell you how I created the chroot?18:12
smbtseliot, pastebin /etc/dchroot.conf or whatever18:13
apwtseliot, well the command you typed to get in there you should be able to cut-n-paste18:13
apwand what smb said :)18:13
smblamont, Doing that discussion I am not sure the dchroots are all correct on zinc here18:14
lamont"that discussion"?18:14
smblamont, Trying to find out why tseliot 32bit chroot tells him x86_64 in uname -m18:15
lamontdid he say 'linux32 dchroot'?18:15
smblamont, The I looked at zinc for reference and maverick and lucid have linux32 in the config for -i386 but not hardy or karcmic18:15
tseliotapw, smb: there's no such directory http://pastebin.ubuntu.com/504030/18:16
lamontsmb: fixed18:16
lamontthat is, tseliot: pls try now?18:16
smblamont, Now thats, service :) thank18:16
smbs18:16
tseliotlamont: what shall I try?18:17
lamonttseliot: the 32 bit dchroots on zinc should now think they're 32-bit, even when you don't say 'linux32 dchroot'18:17
smblamont, The notice of zinc was just coincidence and has nothing to do with what tseliot actually does18:17
lamontmeh18:17
* lamont goes back to sleep18:17
tseliotapw, smb: I created my chroot with pcreate -a i386 -d lucid mychroot18:17
apwtseliot, whats in /etc/pbuilder*18:18
keestgardner: so, dmesg says this:18:18
kees[    0.943957] tg3 0000:01:02.0: PCI INT A -> GSI 30 (level, low) -> IRQ 3018:18
kees  30:  212807004          0          0          0   IO-APIC-fasteoi   eth018:18
keesso I guess tg3 is there, but it's not clear to me if that's for tx or rx18:18
tseliotapw: buildd-config.sh  and pbuilderrc but they're pretty useless as my ~/.pbuilderrc overrides them18:19
keestgardner: any clue how to further debug?18:19
tgardnerkees, maybe you could futz noapic, etc18:19
tgardnerkees, yeah, boot with noapic18:20
smbtseliot, Unfortunately I never use pbuilder, so I am not really sure how tings works out there or where we find things... :/18:20
keestgardner: ok, will give it a shot18:20
tseliotsmb: ok, np18:21
tseliotapw, smb: thanks for your help18:21
smbtseliot, Generally the problem seems to me that the build may somewhere try to find out which architecture it is running on with uname -m and then getting confused when it is 64bit which the linker in the 32bit environment does not know18:22
tseliotsmb: yes, that's likely. I'm wondering how apps are supposed to find the chroot's arch in pbuilder...18:24
smbtseliot, Sort of I thought that pbuilder, too should need to use the 32bit personality when starting a 32bit chroot , but I cannot say how you would tell it. Somehow I would expect it to do so when you pass -a i38618:25
tseliotsmb: yes and I guess "-a i386" is stored somewhere18:26
tseliotI'm using pbuild which is a wrapper for pbuilder18:27
smbtseliot, May that be something pitti wrote?18:27
tseliotsmb: mterry did18:27
smbtseliot, So maybe its time to ask people who may understand those tools. ;-P18:28
tseliotsmb:  that too ;)18:28

mpoirierjust following up on your email.23:33
ogasawarampoirier: did my feedback make sense?23:33
mpoirier1) I thought the SRU process was a two-step process.23:33
mpoirierI understand it doesn't have to be.23:33
mpoirieryou can write the SRU at the same time you submit the patch.23:34
bjfmpoirier, normally, you have a bug, you modify the bug to have the SRU justification and then you submit a patch containing a buglink and the SRU justification23:35
ogasawarampoirier: yep, what bjf said23:35
mpoirierOk got it - the first and only time I did an SRU, the patch had already been submitted.23:36
mpoirierI'll send again.23:36
bjfmpoirier, you may also want to look at: https://wiki.ubuntu.com/Kernel/Dev/StablePatchFormat23:38
bjfmpoirier, what this doesn't go into detail about is that the SRU justification is part of the email23:39
bjfmpoirier, even for a single patch there is usually a cover-letter email, and that contains the SRU Justification23:39
ogasawarampoirier: I'd also update the commit message title to be pre-fixed with "UBUNTU: SAUCE:"23:40
ogasawarampoirier: that way whomever applies it doesn't have to fix it up23:40
bjfmpoirier, what ogasawara just said is covered in the above wiki page23:40
mpoirierbjf: ogasawara: the original author submitted 6 patches and we all want them, meaning they should all be part of the SRU.  Do I have to submit all 6 patches individually or can I prepare a pull request with all 6 patches included ?23:59
