ogasawaradavmor2: able to get the latest test kernel installed and tested?  just posted a comment to the bug.13:05
ogasawaradavmor2: I'm planning to upload our alpha3 kernel today, so would like to get this resolved in time if we can.13:06
davmor2ogasawara: ah okay so the newer kernel might of been over riding it?   the RAlink driver has a glitch but it's really hard to get it to reproduce reliably,  every now and again it will drop out and not reconnect, disable the wifi and enable it again or flick the wifi switch off and on and it connects and works fine till it decides to drop again13:13
davmor2only happened twice13:14
davmor2today it hasn't dropped at all13:14
ogasawaradavmor2: that ralink driver is still noted as experimental, so I'm not too surprised it might still have some issue13:14
davmor2ogasawara: Yeap I was just forewarning you13:15
davmor2ogasawara: on the whole it's fine13:15
ogasawaradavmor2:  if you're maybe able to find a good reproducer, might be good to open an upstream bug13:16
davmor2ogasawara: right so I've knocked some of the old test kernels off and am trying again now13:16
ogasawaradavmor2: cool13:16
davmor2ogasawara: I will do it's trying to get it to reproduce on spec at all currently13:17
davmor2ogasawara: okay so I reboot I have no wifi but is the kernel right now as it still doesn't look it http://paste.ubuntu.com/654489/13:33
ogasawaradavmor2: so that looks like the mainline v3.0 kernel, care to make sure that's uninstalled?13:33
davmor2ogasawara: will do although I though I already had once13:34
davmor2ogasawara: right purged from the system and now to try again13:39
ogasawaradavmor2: thanks, sorry for all the confusion13:39
tgardnerjjohansen, so what patches went into your test kernel at people.canonical.com/~jj/linux-image-2.6.38-11-generic_2.6.38-11.47~lp813748_amd64.deb ?13:49
ogasawaratgardner, apw, bjf[afk]: wanna mumble after I'm done with the release meeting this morning?13:49
tgardnerogasawara, wfm13:49
jjohansentgardner: it was the full set listed in the redhat patch, the tree was on tangerine13:50
jjohansentgardner: I can recreate13:50
jjohansenjust give me a few min13:50
tgardnerjjohansen, well, attach them to the bug report. thats about the only permanent place.13:50
jjohansentgardner: ack13:51
davmor2ogasawara: finally got the right one, no wifi13:52
ogasawaradavmor2: ok, seems to be something in our overlayfs patches.  gonna require a few more test iterations to narrow down which one and not sure we'll be able to resolve in time for the Alpha 3 upload.13:53
ogasawaradavmor2: will kick off the next test build...13:54
davmor2ogasawara: go for it :)13:54
tgardnerogasawara, overlayfs isn't loaded automatically (I think), so how could that affect wifi ?13:55
ogasawaratgardner: does seem a bit odd that it would have any affect at all13:56
tgardnerogasawara, well, it could have a memory corrupter if loaded. is it getting loaded ?13:56
ogasawaradavmor2: ^^ can you check for the overlayfs module13:58
ogasawaradavmor2: can you also double check that you indeed had the following test kernel installed when you confirmed it was working?  http://people.canonical.com/~ogasawara/lp814882/good/linux-image-3.0.0-7-generic_3.0.0-7.8~lp814882v3commitf59f91_i386.deb13:59
davmor2ogasawara: yeap right kernel this time it was replacing 3.0.0-7-generic in the grub menu14:00
apwogasawara, there are a couple of generic patches in the start of the overlayfs stack, if tis not working pull it14:00
lilstevieIm getting this error while trying to build a kernel package: "Checking for dupe aliases in tegra...14:00
lilstevierun-parts: debian/tests/check-aliases exited with return code 2"14:00
apwogasawara, though they are all vfs related iirc14:00
davmor2ogasawara: how do I check for the modules is there an lsmod or something like that?14:01
ogasawaradavmor2: yah, do an lsmod14:01
davmor2ogasawara: no overlayfs listed in lsmod14:03
apwogasawara, so why do we think its overlayfs14:04
ogasawaraapw: only because I built him a test kernel right up to before we applied the overlayfs bits, and it worked.  with the overlayfs bits, fails.14:04
ogasawaraapw: you by chance have a netbook with broadcom?14:05
apwogasawara, thats pretty conclusive14:05
ogasawarabug 81488214:05
apwogasawara, yep14:05
ubot2Launchpad bug 814882 in linux "BCM-sta driver stop working with the latest kernal update" [Medium,In progress] https://launchpad.net/bugs/81488214:05
ogasawaraapw: have you thrown the latest 3.0.0-7.8 kernel on there by chance?14:05
ogasawaraapw: I'd be curious if you're able to reproduce14:06
=== bjf[afk] is now known as bjf
apwogasawara, if its that conclusive rip it out and give him another test kernel with it off14:06
ogasawaraapw: ack14:07
apwas in reverted, and it that sorts him, then lets drop it for A3 and scratch head, how it could affect wirelss14:07
apwi suspect its as likely a kernel layout issue as anything else14:07
apw ogasawara is BCM-sta == the wl driver ?14:07
tgardnerapw, I think so since he's complaining about jockey installs14:09
tgardnerBroadcom Corporation BCM431214:09
apwi have a 431314:10
davmor2ogasawara: is it worth me double checking the other kernels to ensure I was looking at the right one when they were working?14:10
apwtgardner, can you remember which one is supported by the staging driver14:10
tgardnerthere is some overlap, so I'm not sure I ever knew for sure.14:11
ogasawaraapw: can't off the top of my head14:11
apwok14:11
ogasawaradavmor2: yes, double check http://people.canonical.com/~ogasawara/lp814882/good/linux-image-3.0.0-7-generic_3.0.0-7.8~lp814882v3commitf59f91_i386.deb14:11
ogasawaradavmor2: that should work14:12
ogasawaradavmor2: or so you claimed14:12
apwdavmor2, you say the driver "uninstalled itself" and "cannot reinstall it with apt-get"14:14
apwwhat error do you get when you try and reinstall it with apt-get14:14
davmor2apw: ah pass I can find out after one sencond14:16
davmor2ogasawara: sorry it look like I might of booted into the wrong kernel with that one it's not working and I've double checked it this time :)14:21
ogasawaradavmor2: ok, lets try to walk back through these then14:21
ogasawaradavmor2: retest http://people.canonical.com/~ogasawara/lp814882/good/linux-image-3.0.0-6-generic_3.0.0-6.7+lp814882v1_i386.deb14:23
kirklandapw: are there instructions in the wiki for how to add a minor patch to an Ubuntu kernel and push to a PPA for building?14:25
lilsteviehttp://pastie.org/229006914:25
kirklandapw: these aren't for me;  I need to pass them on to someone14:25
davmor2apw:  bcmwl-kernel-source is already the newest version, with remove and install it does just that.  so no error just it's already there14:26
lilstevieI saw that ogra had a similar issue when googling the error but following what was said after that didn't seem to work14:26
apwdavmor2, hang on there was a bug with dkms not rebulding dkms things which was fixed really really recently14:26
apwwhat version of dkms do you have right now14:26
davmor2apw: 2.2.0.1-0ubuntu114:27
apwdavmor2, can you tell from the apt logs when it was installed for you14:30
davmor2apw: it was install way back I'll check for you though14:31
awilkinskirkland, I haven't so far been able to get a Kernel / PPA going14:32
awilkinskirkland, I have built kernel debs locally though14:32
awilkinsI'm not sure that the kernel builds are integrated into Soyuz anyway ; the kernel team seem to use git and the Bazaar imports are just there to be useful14:34
apwdavmor2, the update is only 2 weeks old14:35
davmor2apw: I have kernels 3.0.0-5 on here and I'm pretty sure there is one before that too14:36
davmor2ogasawara: That one fails now I'm looking in the right place, I think I must of been using that mainline the whole time as it was the newest kernel version14:37
davmor2apw: what the new version of dkms or do I have it installed?14:38
apwdavmor2, the version of dkms until this latest update would randomly decide that it didn't need to make external modules14:39
jcastrosconklin: ok, the old forum threads have been deindexed, can you try a few queries and see if anything bad shows up in google?14:40
apwdavmor2, you seem to have it installed now, which is why i am interested when it became installed14:40
davmor2apw: the driver worked fine in 3.0.0-6-generic then when it updated to 3.0.0-7-generic it stopped,  ogasawara has given me a newer mainline version that has the wifi working if I understand correctly14:41
ogasawaradavmor2: you confirmed mainline 3.0-rc7 was working, so I'd like you to retest that the final v3.0 is indeed broken as that major change between 3.0.0-6.7 and 3.0.0-7.8 is the rebase from 3.0-rc7 to 3.0 final14:43
ogasawaradavmor2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.0-oneiric/14:43
apwdavmor2, right so in each test you confirmed the running kernel version, and whether there was a wl loaded ?  yes ?14:44
apwogasawara, are you giving davmor2 different kernels with the same abi ?14:44
davmor2apw: I thought I had but it seems not which is why I'm going back over it all now14:45
apwand if you don't have wl, we'd want to know waht modprobe wl says too14:45
davmor2apw: is it just wl for the module name if so it say "Module wl not found"14:48
apwdavmor2, well i'd want that confirmed too14:48
apwand when we are in that situation i want to ask dkms to rebuild so we can check the build logs14:49
jjohansentgardner: attached, though I don't think all of the patches should be necessary for this particular bug, but I haven't weeded through them yet.14:52
tgardnerjjohansen, please keep working it to narrow down to the minimum set.14:55
davmor2ogasawara: right 3.0.0-0300-generic Doesn't work, which wsa right it was the modded rc7 that did from memory14:56
jjohansentgardner: ack14:56
tgardnerplus, lets use the public bug. there are no real secrets here.14:56
apwdavmor2, ok can you look in /var/lib/dkms/bcmwl/5* and see what directories you have14:57
apwdo you have one called 3.0.0-0300-generic 14:57
apwdavmor2, and you confirmed that modprobe wl says "Module wl not found"14:58
davmor2apw: /var/lib/dkms is empty bar dkms_dbversion and modprobe wl still says "Module wl not found14:59
davmor2"15:00
apwyou have _no_ bcmwl directory even15:00
davmor2apw: Nope 15:01
apwdavmor2, ok then i think we want to uninstall and reinstall the bcmwl-kernel-source and can you pastebin all of the output that produces15:02
davmor2ls15:05
davmor2apw: now there is15:05
davmor2apw: http://paste.ubuntu.com/654555/15:07
apwdavmor2, and modprobe wl now ?15:07
davmor2apw: FATAL: Erro inserting wl (/lib/modules/3.0.0-0300-generic/updates/dkms/wl.ko): Operation not permitted15:09
davmor2Error even15:09
apwdid you do that as you or via sudo15:10
davmor2apw: no that went through now D'oh15:10
davmor2apw: and now I have wifi15:11
apwdavmor2, so now we need you to re-install the linux-image .deb for the latest release kernel which didn't work15:11
davmor2apw: the one from the repo's correct?15:12
apwyou should find a copy of the .deb in /var/cache/apt/archives15:12
apwyes the one from the repos15:12
apwand again i want a pastbin of the output15:12
davmor2apw: grrrr it looks like it is installing the version that I install from ogasawara rather than the version from the repo :(  let me see if I can kill that and try again15:20
* ogasawara back in 2015:21
davmor2apw: right installed linux-generic and linux-headers-generic which grabbed 3.0.0-7-generic from the repo,  no wifi,  Fatal: Module wl not found.   http://paste.ubuntu.com/654574/ was the install and /var/lib/dkms/ still has the bcmwl folder in it15:43
apwdavmor2, ok whats in /var/lib/dkms/bcwml15:44
davmor2apw: the bcmwl folder only lists the 3.0.0-0300-generic-i686 kernel15:44
apwdavmor2, what does dpkg -l | grep 3.0.0-715:45
apwsay15:46
davmor2apw: exact contents are 5.100.82.38+bdcom kernel-3.0.0-0300-generic-i686 for completeness15:46
davmor2apw: http://paste.ubuntu.com/654579/15:47

davmor2apw: http://paste.ubuntu.com/65458616:04
apwdavmor2, ^^ what smb said16:04
davmor2smb, apw: is that another sudo one?16:05

apwdavmor2, could you pastebin /usr/lib/dkms/dkms_autoinstaller please16:12

apwdavmor2, one sec let me see if i can find a fixed dkms16:17
apwdavmor2, u t16:17
apwdavmor2, i think if you uninstall brcml-kernel-source and reinstall it, it will fix you current kernel version16:18
