sugnanhello, am using Ubuntu 10.10 (Maverick), when i tried to compile the linux kernel of version 2.6.36 and 2.6.37( my default version is 2.6.35), i get the error mount mounting none on /dev failed: no such device, when i try to boot. can someone please help, am a newb and compiling kernel for the first time. is it because the ubuntu version am using doesnot support this version06:14
sugnanis it the right channel to ask question regarding ubuntu kernel  development ?06:23
RAOFYes.06:25
sugnanRAOF, am using Ubuntu 10.10 (Maverick), when i tried to compile the linux kernel of version 2.6.36 and 2.6.37( my default version is 2.6.35), i get the error mount mounting none on /dev failed: no such device, when i try to boot. can someone please help, am a newb and compiling kernel for the first time. is it because the ubuntu version am using doesnot support this version06:25
RAOFFirst, the meta-question: why are you building a new kernel?06:26
sugnanactually i wanted to upgrade to the latest version, and i have added few user defined protocols in it06:27
sugnanRAOF, i have made my own device, in order interact with it i have designed my own protocol, so i have added that protocol in the linux kernel code, now i want to compile it, but i ended up with this problem06:29
RAOFI'm not familiar with that specific problem; it sounds like you perhaps haven't built in all the necessary options, such as devtmpfs?06:33
sugnanRAOF, ya i get some error relating devtmps too06:34
sugnanRAOF, can i just know how to compile the modified kernel for the current ubuntu am using, is it necessary that i need to compile the whole ubuntu? or is it necessary that i compile the same version of the kernel am having by default ?06:39
RAOFI'm not sure what the question is.  It's certainly not necessary to recompile anything other than the kernel, and it's entirely possible to use different kernels; the kernel team maintain a couple of different mainline builds, which work.06:40
sugnanRAOF, thanks06:41

sconklinFor bugs which are not verified and have the fix reverted, we can set them "wontfix" or "incomplete". Any thoughts from anyone about this?18:41
bjfsconklin, personally, i like "wontfix" and require a new bug and full, new SRU process for the related patch18:42
sconklinThat's what I proposed, but I've heard the arguments that 1) wontfix isn't accurate, as we will fix it if it's tested, and 2) incomplete accurately reflects what happened. I'm afraid that bugs already turn into a mess too often, and we use them essentially for tracking tasks, so we should open a new bug. Otherwise, we also have to unwind the "fix committed" states18:45
bjfsconklin, but once a bug "needs verification" then it is more than just a bug, it is also tracking a process, which the bug states were never intended/designed to be for so it seems we can make them mean anything we want (i know this is a bit of a stretch but i hope you get my drift)18:48
sconklinbjf: right - we have no way to re-use a bug for another trip through the process, so I think we need to close it and start another. We agree?18:51
bjfsconklin, agreed18:52
jjohansenugh, that is less than ideal18:52
bjfwhat would be ideal then?18:53
sconklinI'm open for suggestions18:53
sconklinby the way, I think we'll also break patchwork, when people reply to earlier email to re-request acceptance of a patch that was previously accepted. But we can deal with that later18:54
jjohansensconklin: I don't have a better suggestion, ideally you could reuse the bug.  Having to close and start a new bug is just extra work and an extra step that mistakes can happen in.  /me was just kvetching that the process isn't as nice as it could be if it had been designed to accommodate SRU needs from the start19:10
ogasawarasconklin: hrm I slightly in favor of re-using the existing bug.  It should be simple enough to hammer out an arsenal script which posts a comment about the revert, sets the bug to Incomplete, and resets the tags.19:24
ogasawarasconklin: having to open a new bug, re-submit/re-ack patches is going to get annoying.  The patches and ack's should still be good, it's just the verification that failed.19:25
lamonthow do I disable ipv6 on just one interface?  or can I?19:26
* lamont finally finds it19:31
sconklinogasawara: the actual agreement that was reached at UDS was that bugs will be closed "wontfix". There was a lot of discussion at UDS, and I feel like we're having it all over again.19:42
sconklinIt's not that I'm opposed to refinement, but I do want to end discussion at some point and try something19:42
ogasawarasconklin: ack19:42
ogasawarasconklin: and we can always refine the process if we find our approach need tweaking19:43
sconklinMy overriding goal from a selfish point of view is to minimize the amount of work that the stable team has to handle, as I'm not sure we will be able to keep up.19:44
sconklinAnd I am very open to changing things that don't work.19:44
sconklinI'm also concerned about creating still more bugs which seem to live forever19:44
bjfogasawara, i'm curious to your thinking on not having to re-ack patches, once a patch has been reverted how would it get back into the repository?19:45
sconklinI'm frustrated by having to use a bug tracking tool to implement process, but it's what we have . . .19:45
sconklinso bjf - to recall some of the discussion that we had at UDS . . . One proposal was just to revert the patches and leave them on the tip of the tree until they eventually get tested.19:47
sconklinBut this would lead to an ever-increasing load of cruft that we have to carry around.19:47
bjfsconklin, you'd revert, re-upload, then reapply?19:47
sconkline also wanted to get assurance by whoever re-proposed the second SRU that there was a commitment to testing19:47
ogasawarabjf: I guess my thought process is that the patch was already reviewed and ack'd for it appropriateness, the fact that it was reverted due to failed verification doesn't actually reflect the patch itself is bad.  so if a reporter said "oops I was on vacation and wasn't around to test" we could just re-apply it.19:47
sconklinbjf: yeah - I'm NOT recommending that, it was just an idea that was rejected19:48
ogasawarabjf: and we could tag the bug with something like "re-apply" or whatever to know which patches to shove back in for the next upload.19:50
sconklinogasawara: from the end user's POV I see this - if they're on vacation for a week and miss verification, we should make it easy for them to reapply. And honestly, getting everything correct on an SRU request is hard enough as it is.19:50
sconklinto totally throw a wrench in this - there are bugs which track the same fix in multiple releases19:52
ogasawarasconklin: ugh, now that could get messy19:52
bjfsconklin, known issue, and the question is when someone marks it verified which release were they referring to?19:53
sconklinexample: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/58074919:53
ubot2Launchpad bug 580749 in linux (Ubuntu Maverick) (and 5 other projects) "Pulseaudio is not running VT1708 (affects: 2) (heat: 33)" [Undecided,Fix committed]19:53
ogasawaraalmost seems you'd need to make it verification-done-<release>19:53
sconklinbjf: This is currently handled manually by pitti. As he described it to me, when someone says it's verified for a release, he leaves both the verification-needed and verification-done flags set until every release is verified, then removes the verification-needed tag.19:54
sconklinI think we should probably change to verification-xxxxx-<release>, but this requires changes to Pitti's scripts that he uses19:55
bjfsconklin, but how does he know which release the commentor tested? does he ask them? (i'm assuming that he does)19:55
sconklinbjf: dunno, if it's not obvious from the comment19:55
bjfsconklin, if we ignore reverting patches, the fact that we now require certification testing of the proposed releases puts us in a much better place than we were before19:56
sconklinI'm worried that we have so much home-grown processes and so many tools which are dependent on special tags, text formatting in changelogs, etc, and so little of it is documented, that we have potential to break things unless we add more unique tags for our use.19:57
sconklinbjf: you mean if we don't revert? I don't think that's an option. But yes, I think we get more goodness from testing than from any other piece of this19:58
bjfsconklin, frankly the fact that we are using tags (which any user can add/remove/modify) for processes is not a good thing19:58
bjfsconklin, i'm not suggesting not reverting (though i'd like to)19:58
sconklinbjf: agreed, but today;s not the day for that fight. It's beyond the scope of what we can influence19:59
sconklinand reverting patches is being done to bring us in line with the release guidelines for Ubuntu, so unless they change, I'm trying to do a better job of compliance with those. I think requiring verification is a good thing.20:00
sconklinIf we can manage the repositories, I don't think it would be terrible to just revert and reapply patches that don't get verified, then drop them after three strikes or something. We can think about that as an option if the process is too difficult to manage with reverts20:03
sconklin(that was more thinking out load than anything)20:04
ikepanhcsconklin: once verification for an SRU bugs finished, shall bug reporter modify the tag from verification-needed to verification-done or wait SRU team to review the verification and modify the tag?20:07
sconklinSo far, we've let the user do it, and even instructed them to do it in the text added to tge bug20:08
sconklinikepanhc: the reason is that I want to avoid another task that the stable team has to do on the verification deadline day, which is to open all the unverified bugs and read the comments to see whether it's verified. I want all of our operations to be scalable to more fixes without requiring more time, and I want them all to be able to be automated with scripting when possible.20:11
ikepanhcsconklin: make sense to me20:12
jjohansenhowever relying on reports to set tags right is not going to work well20:13
ikepanhcsconklin: another question, for bug 640214, everything is fine with karmic to enable Intel B43, but not on lucid, x-x-v-intel driver is not updated (maybe because nomination for lucid is not accpeted yet), can I just put verification-done there? (for kernel, it is done)20:14

sconklinogasawara, bjf: another argument I just thought of in favor of NOT closing unverified bugs - they may have milestones set which are important, and be requiring new bugs to be opened, we may be proliferating cruft into the release and milestone tracking tools - this is another example of magic processes that work off of bugs that I don't fully understand20:14
sconklin".... by requiring new bugs ... "20:15
bjfjjohansen, i agree completely, but we do it all the time20:15
sconklinbjf, jjohansen: so more accurately - instead of eliminating the need to review every unverified bug before reverting on revert day, I'm hoping to minimize the number that need to be looked at, by asking people to set the tags. I think review will still be required.20:17
bjfsconklin, so, we are going to have to visually inspect every bug to make sure the bug was not left on by mistake nor removed by mistake20:18
jjohansenbjf: yep, however we seem to be doing it more and more, and basically fear its getting to be too much20:18
jjohansensconklin: what bjf said20:18
bjfsconklin, sorry "bug" -> "tag"20:19
sconklinI think that we at least have to check the ones without a verification-complete tag and see whether a comment says they are verified. For the converse, we have to decide what it means if someone sets the verification-done tag with no comment or explanation.20:20
sconklinAs it stands now, we let them pass.20:20
sconklinand I think that now, no one pays much attention to bugs unless they are verification-needed. pitti would know. 20:23
sconklinI've asked him to join this room - he's away at the moment. 20:23
sconklinOn monday we're going to do ~something~ to the unverified bugs - either close wontfix, or set to incomplete. (and we'll revert the changes). Since we're unsure about this, it seems to me that setting incomplete is the safer of the two options until we figure it out. Agree? Disagree? There will be text added explaining everything that is done.20:26
* jjohansen -> lunch20:26
ogasawarasconklin: agree, setting to incomplete for now seems better imo.20:27
