* smb pries open his eyes08:13
smbcking, g'morning08:18
ckinggood morning!!!08:18
smbWoah! Not so enthusiasticly :-P08:19
ckingoh, ok, how about:  yawn, morning... *sigh*08:19
cking;-)08:19
smbAh much better :=08:20
cooloneygood morning smb and cking 08:20
ikepanhcgood morning08:20
smbcooloney, morning o king of SMS08:20
cooloneysmb: i guess no SMS here. hehe08:20
ikepanhcsmb: I read your email, what you mean is we plan to removing control*?08:21
ikepanhcsmb: I look into the hardy tree, looks like netbook branch is using the same control/control.stub with master branch08:22
* cking starts trawling through a load of BIOS bugs08:22
smbikepanhc, Can you give me more context of what I said? I am not sure what exactly I wrote when. I don't think I will remove any of the control files on the master branch.08:23
smbikepanhc, Maybe you mean my stuff about removing kernel-versions08:24
smbin your branch08:24
smbas you removed the other two files08:24
ikepanhcsmb: if master branch not to remove them, I vote for not to remove them in netbook branch...08:24
ikepanhcsmb: sorry for making you confusing because of changing mild08:25
smbikepanhc, No worries. Its done later, so why not think about it. I am just a bit conservative there. As Hardy is out that long08:26
smbikepanhc, Still you would be free to do your own thing there.08:26
smbWhatever seems better to you08:26
smbActually the lpia branch is already different in that it checks no abi files08:26
ikepanhcsmb: let me 'fdr clean' again to make sure what will happen on those three files08:28
smbikepanhc, I guess all three will be re-created. The main reason for keeping them was to avoid a failure when you run something else. And clean is not the most obvious way to create something.08:29
ikepanhcsmb: for Jaunty and later release, we need to 'fdr clean' before doing anything else, do we expect the same on hardy release?08:32
ikepanhcanything means 'debuild -S' and 'fdr binary'08:32
cooloneyikepanhc: debuild -S is a command to build source package08:33
smbikepanhc, I would not, but more because a lot of things changed after Hardy. So I am prepared to difference there08:33
ikepanhccooloney: I know08:33
cooloneyikepanhc: fdr bianry is for building binary package.08:33
smbikepanhc, We need to rename cooloney to man-bot. :)08:34
ikepanhc:)08:34
smbikepanhc, For me its just one more difference of things in Hardy compared to the later releases that I don't want to make it different as that might surprise other people. (same with Dapper)08:36
cooloneysmb and ikepanhc, hehe, man-bot is more popular than bugbot08:36
ikepanhcsmb: agree, so I prepare the tree again, not to remove control and control.stub this time08:37
smbcooloney, Maybe as popular as the talking office clip... >:-P08:37
ikepanhcsmb: just "as it was"08:37
jk-"it looks like you're trying to package a kernel ..."08:38
smbjk-, :)08:39
ikepanhcbtw, the kernel-version is re-created by kernel-wedge?08:39
smbikepanhc, Ok. I was saying you could keep it as you like. But there actually might be a sort of dependency when using the rebase script later. And for kernel-version, yes08:40
* apw thinks we should rip them out of hardy master too ...08:48
apwrend, tear, shread08:48
smbapw, Its a needless change to a working environment08:48
smbYou just should not expect that an old release behaves the same as a new one08:49
* apw puts his mining hat on ... "i'll get them captain"08:49
apwsmb, by that measure debian commonisation back to jaunty makes no sense, but i really have no firm oppinion08:49
smbI am not really sure about Jaunty either. But at least Jaunty is more similar to Karmic and Lucid that to Hardy08:50
smbIn Hardy we have custom binary build blocks which are nowhere else08:51
apwsmb, if we wait long enough jaunty will fix itself :)  and no i wouldn't suggest any major changes to hardy anyhow08:51
apwthough i am not sure that removing those built files would be such a big change, it has stopped a lot of error in later releases08:52
smbapw, If we wait long enough even Hardy fixes itself... All just a matter of time. :)08:52
apwheh indeed08:52
ikepanhcfixed itself.... I like it08:53
ikepanhcbtw, I heard hardy netbook branch will fix itself at March 201108:53
smbWell yes, you cannot create a source package without them rather than with the wrong files08:53
smbikepanhc, Then you would be more lucky than me08:54
smb:)08:54
ikepanhcsmb: ah, yeah, the EOL for you is to 201308:55
apwsmb when does hardy desktop support finish ?08:55
apwis that the same time as dapper comes off completely ?08:55
amitkweber finance loan company <weberfinanceloan@gmail.com> has been08:55
amitksuccessfully subscribed to kernel-team.08:55
jk-sweet08:56
amitkapw: ^^ what are the chances we've got a spammer08:56
smbapw, I am just thinking that there might be people out there that use the Hardy git repo as a base and might get surprised. Sure it would "just" be a educational process. But then, I usually update the files on abi bum. Or find out on my test builds...08:56
smbapw, Dapper-server goes off in Apris 201108:56
apwsmb we like supprising people on my side of "conservatism valley"08:56
smbapw, We know we live on opposite ends of that. :)08:57
apwsmb, so i assume as hardy is 2 years behind, and desktop is 2 years less than server, that it goes at the saem time ?08:57
apwsmb, na i live in the middle, tim lives on the other side :)08:57
smbhehe08:57
smbapw, I usually check the times on the wiki. And usually I am surprised every time I do08:58
apwsmb, got a link to the support wiki ?08:58
smbhttp://wiki.ubuntu.com :)08:59
apwi can never find the support info ... i hate the wiki08:59
smbHardy: Destop till Apr-2011 and Server till Apt-201308:59
apwsmb, so we do drop off desktop as we drop dapper, sweet08:59
apwsmb, s09:00
smbOr even https://wiki.ubuntu.com/Releases. Right09:00
apwsmb, shouldn't dapper be on that list ?09:00
apwand i note dapper says june09:00
smbapw, Remember what I said about being surprised09:01
apwwell as it was a .06 that makes sense, though i had heard apr recently for it09:01
smbThere is a last column on the Release page09:01

Sleep_Walkerhi amitk, do I understand correctly that there is currently no driver for SD and framebuffer for i.MX51 based machines?09:37
cooloneyapw: are you reviewing the ti-omap4 branch?09:40
apwcooloney, not that i know of, should i be ?09:41
Sleep_Walker(in upstream)09:42
apwcooloney, oh i see, no i was helping out lag09:43
cooloneyapw: got it, hehe09:47
jk-Sleep_Walker: that's correct09:48
Sleep_Walkerjk-: ah, ok, well, I'm sick this week and I'd like to help a bit - any suggestions what is needed and what doesn't anyone work on?09:51
jk-Sleep_Walker: I think it's just a matter of having the time to work on it09:51
Sleep_Walkerjk-: I see, I'll try to have a look on SD then09:55
jk-Sleep_Walker: yeah, that'd be my preference09:55
jk-but you may want to catch amitk first to make sure.09:55
Sleep_Walkerjk-: ok, I first read some doc10:11
jk-excellent plan :)10:13
Sleep_Walker:b10:13
cooloneyapw: if i change a module driver to compile it into kernel, need i remove the module name from the abi module list file?10:21
cooloneyapw: is that the right way to avoid the module check failure?10:22
apwyou need to do something to stop the error yes10:22
apwyou can either remove it from the modules list or you can add it to modules.ignore10:22
cooloneyapw: but removing is removing from the previous ABI module list file, right?10:24
cooloneyapw: so after we bump abi, the new module list file of the new abi won't contain the module name which i removed, i think10:25
apwyes10:25
apwcorrect10:25
cooloneyapw: ok, i understand. thanks10:25
amitkSleep_Walker: correct, nothing in mainline. But I'll take patches :)10:36
trapmaxduring system update & restart, noticed this: http://pastebin.com/cF1TVjx110:50
Sleep_Walkeramitk: there are imxmmc.c and mxcmmc.c for other i.MX processors, can it be good start or it is mostly incompatibile?11:35
apwtrapmax, that looks liek its telling you that you have queueing state for a device which is configured not to do queuing, odd11:36

jcastroogasawara: ok21:25
jcastroogasawara: ok so during UDS I asked about enabling fscache now that upstream has removed the experimental tag. The module looks enabled and working and all that good stuff in maverick, but # CONFIG_NFS_FSCACHE is not set21:26
jcastroshould I file a bug to ask for someone to enable the modules for the filesystem support?21:26
jcastro(The module and userspace thing don't seem to work without it otherwise)21:26
jcastroalso, there's a corresponding config for AFS and 9p, but I don't think people use the latter. No idea who uses AFS these days21:27
apwmanjo, superm1 suggests you also ask for testing from ubuntu-mythtv@l.u.c21:33
manjoJFo, ^ CFT that list ? 21:33

jcastrotgardner: apparently CONFIG_FSCACHE_STATS=y and CONFIG_FSCACHE_HISTOGRAM=y help with debugging, maybe a good idea to have on during alpha/beta?21:40
tgardnerjcastro, it depends if it has a runtime impact. I'm still looking at those21:41
jcastrooh ok.21:41
ogasawarajcastro: yep, typically I'd say file a bug with the request to enable the config option, but in this case I'd say we just use 44052221:50
