tgardnercking, really? I would not have expected that the network subsystem was alive in the earliest phases.14:24

jsalisburyhenrix, ping14:26
henrixjsalisbury: hi. just a quick question14:26
henrixjsalisbury: i believe that bug #93819514:27
ubot2`Launchpad bug 938195 in linux "kernel 3.2.0-17-generic crashes constantly" [High,Confirmed] https://launchpad.net/bugs/93819514:27

henrixwhat do you think?14:27
henrixi'm asking you because you initially tagged it as rc614:27
henrixjsalisbury: btw, i have built a test kernel for this (or these) bug(s)14:29
jsalisburyhenrix, yes they do look like dups comparing the trace14:29
jsalisburyhenrix, The bug reporter for 938195 has been unable to reproduce the bug by enabling rc614:30
henrixyeah, and there's another dup for these bugs (924486)14:30
jsalisburyhenrix, ok14:30
jsalisburyhenrix, we can pick one as the "Master" bug and mark the others as duplicates of it14:31
henrixjsalisbury: the reporter of 938195 ends up saying at some point that his system crashed w/ rc614:32
henrixjsalisbury: check comment 34)14:32
henrixjsalisbury: i was planning to pick the oldest bug as the master14:32
henrixjsalisbury: is this ok?14:33
jsalisburyhenrix, sounds good14:33
henrixjsalisbury: ok, cool.14:33
henrixjsalisbury: and thanks14:33
jsalisburyhenrix, np.  Is this the same patch that is mentined in bug 923512?14:34
ubot2`Launchpad bug 923512 in linux "ath9k wireless stopped working after kernel upgrade to 3.2.0-12" [High,Fix released] https://launchpad.net/bugs/92351214:34
jsalisburyhenrix, actually, probably not.14:35
henrixjsalisbury: let me take a look...14:35
jsalisburyhenrix, They probably are not releated.  923512 was for wifi not working not crashes14:37
henrixjsalisbury: yeah, doesn't look the same. and the patch is not the same14:37
henrixjsalisbury: but i'll take a closer look. they may be related...14:38
jsalisburyhenrix, ok, thanks14:38
henrixno prob14:38
ckingjsalisbury, do we have any trends on ath9k crashing on boot?14:40
ckingcausing an un-bootable system?14:41
jsalisburycking, not crashing on boot, but crashing at run time and producing call traces.14:42
tgardnerogasawara, do you suppose we should more widely advertise the fact that we don't plan to support aufs ? given the deficiencies we've encountered with overlayfs, we may have to change our minds. see bug #90389714:43
ubot2`Launchpad bug 903897 in linux "-virtual kernel missing modules" [High,Fix released] https://launchpad.net/bugs/90389714:43
ogasawaratgardner: yah I saw it.  I ran into a similar bug request the other day and have duped it to that one.14:43
ogasawaratgardner: I've been posting a blurb about aufs to every milestone's TechnicalOverview.  I can craft a more wide spread email.14:44
tgardnerogasawara, given that apw has kept aufs up to date, I'm tempted to just turn it back on. maybe overlayfs will get its problems fixed in 3.514:44
jsalisburycking, There was this one though bug 89458414:44
ubot2`Launchpad bug 894584 in linux "ath9k driver causes kernel panic" [Medium,Incomplete] https://launchpad.net/bugs/89458414:44
jsalisburycking, However, the original bug reporter stated he could not reproduce the issue.14:45
tgardnerogasawara, I know you need more email in your inbox, but perhaps we should request use case scenarios on ubuntu-devel ?14:45
ogasawaratgardner: indeed, I'd like some compelling evidence for carrying it for the next 5 years14:46
tgardnerogasawara, ok, while you're sending out that email I'll go figure out why Lucid doesn't build14:47
ogasawaratgardner: ack14:47
ckingjsalisbury, bug 919815 manifests this problem, but I've seen nobody else with this issue - which makes me wonder if it is a (broken) H/W issue14:52
ubot2`Launchpad bug 919815 in linux "Ubuntu freeze on battery after power on/off - blacklisting ath9k stops freeze" [Medium,Confirmed] https://launchpad.net/bugs/91981514:52
jsalisburycking, hmm, yeah maybe hw issue with the wifi device itself14:57
jsalisburycking, I suppose I can ask him to try an oneiric or earlier kernel to confirm14:58
ckingjsalisbury, well, we could try this out, but I was wondering if we had seen other ath9k regressions - but if not, it is worth trying out a previous version just in case. But my gut feeling is that it is borked H/W15:00
jsalisburycking, no pattern of ath9k regressions similar to this bug15:00
* cking nods. google searches affirm that assertion ;-)15:01
ckinglemme chat to him - he reached out to me privately, so I will plug away at this bug with him15:01
jsalisburycking, ok, thanks15:02
tgardnerherton to the rescue. I see the Lucid build problem is already fixed by bumping ABI15:03

allan_shandIs there any one online at the moment?20:26
allan_shandI have a problem with all of the recent kernels I have some information about the problem here http://askubuntu.com/questions/58763/why-wont-ubuntu-11-04-11-10-boot-after-install20:32
jsalisburyallan_shand, I would recommend opening a bug by running the following from a terminal: ubuntu-bug linux20:33
allan_shandI can't Install ubuntu to start a kernel bug the bug stops ubuntu from being Installed.20:35
allan_shandI ran a verbose boot from the Live disk and the line in the Question at askubuntu is the line it stops at during the boot of the live disk20:36
jsalisburyallan_shand, what version are you trying to install?  If possible, can you see if you can boot from a Live CD?20:36
jsalisburyallan_shand, so you can boot/install 10.04 and 10.10, but not 11.10?20:38
allan_shandAt the moment I have 10.10 on the system I have tried all versions including the current daily build of 12.04 all with the same result.20:39
allan_shandI was able to boot 10.04-3 but since the update to 10.04-4 this also won't boot20:39
allan_shand10.10 will boot /10.04-4 no /11.04 no /11.10 no /12.04 no20:40
jsalisburyallan_shand, can you boot into 10.10 and open a bug?  That way we can gather some information about your system.  That will allow some further debugging and possible testing of kernels.20:41
allan_shandhow should I inform about the bug being about a different kernel?20:42
jsalisburyallan_shand, Just add that information as a comment, and I can add the appropiate tags20:43
allan_shandgive me a couple of minutes to boot and set up the bug thank you for the advice jsalisbury20:44
jsalisburyallan_shand, thanks for reporting the bug!20:44
allan_shandbtw I forget should I run ubuntu bug as sudo?20:47
jsalisburyallan_shand, sure.  If you don't you'll be prompted for the administrative password.20:49

kklimondahey, what's the definition of "SAUCE"? Are those ubuntu-specific patches, or are they backported from staging and other upstream branches?21:34
smosersmb, ping21:39
smoserif you're awake21:39
smoserhttp://paste.ubuntu.com/862565/ is pastebin of cg1.4xlarge, it had a soft lockup on boot21:40
ogasawarakklimonda: SAUCE basically means it's usually a patch which has been submitted upstream but not yet applied to Linus' tree but it is of enough value for ubuntu to carry it.21:50
ogasawarakklimonda: https://wiki.ubuntu.com/Kernel/Dev/StablePatchFormat might help explain21:51
kklimondaogasawara: and can I grep through changelog to see what "SAUCES" have been applied to the precise kernel, or should I just clone the git repository?21:53
ogasawarakklimonda: yep, you should be able to grep through the changelog for "SAUCE"21:53
