spijetGood Mourning!01:40
spijetExcuse me for my bad English, i have a problem with 2.6.30.5 kernel.01:41
spijetWhen i have installed it, it starts, but after ~2 seconds in usplash, it (crashes?) to a black screen with cursor in a upper-left corner.01:44
spijetAnd it is NOT terminal, because i can't switch it.01:45

rtgsmb, what is it you're asking me about the joystick regression? I realize the same patch is upstream, but looks to be incorrect. Are you gonna work with the upstream developers to find a better fix?13:29
smbrtg, I, if asking is the right word, just wanted you to be aware of it. The question is whether this patch is incorrect or the Saitek joystick driver in its use of a certain button code. That is a bit beyond y knowledge, but I am checking on the upstream bug.13:32
rtgsmb, is this causing wide spread carnage, or are we helping more then we hurt?13:50
smbrtg, Spread enough in Jaunty to cause complains. Otherwise I just was notified as I was in the SOB13:50
rtgsmb, you were notified that upstream is changing the patch?13:51
smbNo of the started bugzilla regarding the regression13:52
rtgsmb, ah.13:52
smbBut the initial comment from Dmitry sounds like he also believes BTN_DIGI is for digitizers and not for joysticks13:52
smbto be continued13:52
rtgsmb, ok. I assume this'll find its way into a stable update eventually.13:53
smbrtg, I'd say so. As said, just for you to know when gamers complain to you about it. 13:54
rtgsmb, huh, like _I'll_ hear about it. It'll be Andy that gets most of the noise.13:55
smbrtg, Heh, well he is not around for a bit...13:55

thjcHi all, I need some help debugging a system crash (sudden reboot) which I can reproduce compiling certain files with an arm cross compiler. This seems to be related to the specific revision of the hardware in the machine (ich8 rev3) as I have tried the same hard disk and operation in a similar laptop with ich8 rev4 hardware16:04
thjcalso a centos 2.6.18 kernel doesnt have the issue, but ubuntu Jaunty and Karmic kernels do16:05
amenodoes it always happen while compiling the exactly same file? (you said fileS)16:07
thjcit doesnt always happen, but there are server files that I can set up a bash do while loop over compiling and it will die within 2 mins16:07
thjcno oops messages of any sort, hard reboot. does the same thing if I boot recovery mode and run the compile loop there16:09
dholbachhello everybody16:53
dholbachcan somebody take a look at  https://bugs.launchpad.net/ubuntu/+source/open-vm-tools/+bug/277556 ?16:53
ubot3`Malone bug 277556 in open-vm-tools "should build kernel modules with dkms" [Undecided,Confirmed] 16:53
rtgdholbach, seems like a server team issue. kirkland could probably answer your questions.16:56
dholbachI was pinged about it and know nothing about dkms stuff16:56
dholbachfunnily enough I got another email about something with dkms today16:57
rtgdholbach, its just a method for building external kernel modules (like nVidia)16:57
dholbachright16:57

smoserrtg, the other i spoke with you about -virtual inclusion of acpiphp under bug 36491617:23
ubot3`Malone bug 364916 in eucalyptus "When running Ubuntu as an Eucalyptus VM instance, module acpiphp is not available to be loaded, complicating the use EBS volume" [Undecided,Confirmed] https://launchpad.net/bugs/36491617:24
smoseri'm new-ish to this process... what do you need me to do for a.) karmic b.) jaunty.  17:24
rtgsmoser, You need to send an SRU request with a patch to the kernel team mailing list. Get with smb or ogasawara if yiou have questions. zul can also help.17:26
smoserok. that is for sru. what about karmic?17:27
smbsmoser, Generally (you have a bug, thats point 1) Then send a patch with a short impact, change and testcase description to the kernel-team mailing list. You can add that the same is needed for karmic17:29
smoserthanks.17:29
rtgsmoser, you could also just create the report, then bribe someone on the kernel team to fix it (which might be faster depending on your kernel build skills). I know for a fact that smb is not immune to the charms of beer.17:31
smoserdo you know people who *are* immune to charms of beer?17:32
smbsome are rather into wine...17:32
smoseri'll avoid the shortcut for now, though.17:32
sbeattiesmb: why is the intrepid-proposed kernel still pending?17:32
smbsbeattie, because the sru team is overworked and also because today a potential regression was found which forced me to reupload17:33
sbeattiesmb: ah, okay, thanks.17:34
ogasawarafabbione, smb: re bug 416266, I'll roll a new patch to include enabling for ia64 and hppa.  just going to kick of some test builds first and will resubmit.17:38
ubot3`Malone bug 416266 in linux "Please enable multicast routing support for sparc" [Medium,In progress] https://launchpad.net/bugs/41626617:38
smbogasawara, Just because rtg is thinking this does not mean I am convinced17:38
ogasawarasmb: that's why I'm gonna push the new patch to a different branch and let you choose :)17:39
rtgresistance is futile17:40
smbogasawara, Ok, if we find someone who can verify this works, I am ok.17:40
smbrtg, That is what you think. :)17:40
smbrtg, If you can provide test results, I am fine. Otherwise...17:41
rtgsmb, honestly, for the 4 ia64/hppa users out there, who really cares? I'm not gonna push this particular case, but for the future we _are_ going to continue to maintain a common config settings algorithm.17:43
smbrtg, We definitely should avoid having common options different over different archs. And with the new config system we less likely will forget to do so in the first place. My point is just that even though the change sound logical, it is always a risk I would like to minimize. 17:47
smbMaybe we can ask lamont to test this with hppa and someone else for ia64. A quick boot and network test would be good to make that change more compfortable17:49
rtgsmb, ah, its hardly worth the effort. I'm just chapping your ass :)17:50
smbrtg, And I try to save my ass from the spanking if that 4 users would get regression. :-P17:51
lamontso... if it's a karmic kernel, hppa is not in karmic.17:51
lamontif it's a hardy kernel, then I kinda care17:51
lamontsome17:51
lamonta little.17:51
smbNo we were talking about hardy17:51
lamontia64, yeah I still care17:51
lamonthardy - definitely would love to test a kernel17:52
rtglamont, what are these boxes being used for? Surely not BGP routing?17:52
smbWell at least it would prove that the normal use case is unaffected17:53
lamontrtg: heh. not so much17:54
lamontactually, I am aware of ia64 boxen being used in a very heavy sctp environment, with a routing protocol (OSPF?) under that17:54
lamontOTOH, they're not running ubuntu17:54
rtglamont, huh, then maybe I sit corrected.17:55
lamontrtg: so mostly I just care that the box still boots after I do a dist-upgrade17:58
rtglamont, I'll try to convince smb to not break things :)17:58
lamontand while I have people's attention, I should really check and see if the most recent kernel upgrade on jaunty made it so that windoze XP Pro/SP2 still boots in kvm17:58
lamont2.6.28-11.42 was the last working verison17:59
lamontversion17:59
smbWell when ogasawara posts the update to the config settings I try to get lamont do a quick test to make sure I do not.17:59
ogasawarasmb: I'll CC lamont on the email18:00
smbogasawara, ok, deal18:00
lamont"quick test"...18:00
lamontthat involves being >8PM or so mountain time, or < 7AM18:00
smblamont, Well see it still boots and has a network18:00
lamontOTOH, booting can be done remotely, and if I temporarily brick that box, it's prolly OK.18:01
lamonthrm... I might even have remote serial console on that machine18:01
smblamont, about the kvm thingy. have you spoken with kirkland about that?18:01
lamontsmb: I don't remember.  it's quite possible that I even filed a bug in launchpad18:06
lamontI do know that kvm had changes in the security release that broke things....18:06
fabbioneogasawara: works for me...18:07
fabbionelamont: hey dude18:07
lamontfabbione: on hppa or sparc?18:08
lamontdude18:08
lamontlong time no chat18:08
lamontthough getting dragged out to lunch atm18:09
smblamont, broke in the security. Hm, if you find that bug pass the number to ogasawara. She will add it to our nag-list18:09
fabbionelamont: enjoy lunch :)18:09
fabbionelamont: i tested on sparc, but I can test ia64 and hppa too if needed18:09
fabbionelamont: the netcode is pretty rock solid on "special" endian and alignment anyway18:09
fabbionelamont: so i am not worried to enable it again18:10
lamontsmb: sigh.  looks like the only jaunty-pain-with-kvm I  filed was  353995   BLTs appear broken - moving blocks on the remote leaves cruft18:10
smbfabbione, if you have both other archs too, I am fine with either of you doing a quick test. I just want a bit of it18:11
lamontI'll upgrade and see what breaks later18:11
fabbionesmb: i am not entirely sure I'll have the time to test them properly, but if you can make me test kernels ready, that will help18:12
smbfabbione, Sure I build them and link those to the bug18:13
fabbionesmb: ok cool thanks18:13

Nafallolots of stuff like that on my laptop. should I be worried?18:44
Nafallojaunty18:44
rtg_Nafallo, you should be running a Karmic kernel, or a mainline 2.6.28. Something in the Ubuntu kernel is not quite right wrt ext4. ogasawara might have some test kernels for you.18:45
Nafallohehe. that wasn't really the answered I wanted :-P18:46
rtg_and yes, you should be worried.18:46

* Nafallo goes to read up on it and grab the kernel.18:48
Nafallohmm. can't see the message after reboot with the test kernel.18:56
Nafallois that expected?18:57
ogasawaraNafallo: others commented that the warning wasn't always present, even the orig reporter said they only saw it once19:09
ogasawaraNafallo: what I'd expect is if you do happen to see the warning again, it's only printed once, not repeatedly19:10
Nafalloah. I've only seen it just now and used this as my panic room :-)19:10
ogasawaraNafallo: if you'd be willing to run that kernel for a while and see if it pops up again that'd be great.  If not, if you could still post a comment to the bug that'd be great.19:11

jsteelDoes anybody know how ubuntu kernels are versioned? Specifically I'm looking for what exactly the 60 means in 2.6.24-24.60. I'm trying to create a custom kernel and want to know if I should name it 2.6.24-24foo1 so that I can upgrade it to 2.6.24foo2 and so on. Or should I call it 2.6.24-24.60foo1? I cant find anywhere a reference that describes Ubuntus kernel versioning.20:20
rtg_jsteel, its just an upload number. if you look at the tags in git you can see how they are encoded, 'git tag|grep Ubuntu'20:31
jsteelrtg_: It looks like there are usually 2 or three upload versions. ie 2.6.24-24.59 and 2.6.25-25.60. Why would there be more than one upload version?20:33
awertg_, ping20:45
rtg_awe, dude20:45
awei just updated my macbook to -7, and associated drivers and it's hosed now.  ;(20:46

rtg_jsteel, somewhere in here is a discussion of version numbers: https://wiki.ubuntu.com/KernelTeam/KernelMaintenance20:46
rtg_awe, boot back to -6. the root the problem appears to be buildd related.20:47
aweI tried that, but I still end up at a cmd-prompt20:47
aweso y'all are aware of the problem I take it?20:47
rtg_awe, some of the problems, but they appear to be related to encrypted swap20:48
awelovely...20:48
aweok, well i'll guess i'll switch over to using my old mbpro ( what i'm typing on now ), and look for some guidance on how to fix my macbook later...20:50
rtg_awe, did you have encrypted swap?20:50
awertg_, no, but i do have home-dir encrypt20:50
rtg_awe, going back to -rc6 should have fixed it (I think)20:51
awertg_, it didn't for me...20:51
awertg_, it didn't for me.  sometimes it won't even boot to the grub menu ( 50/50 )20:52
rtg_awe, no that seems like a different problem. can you boot from LiveCD consistently?20:52
rtg_you had issues in Dublin20:52
awehaven't tried yet...20:52
awertg_, the issues in dublin were this box ( mbpro ).  returned it to apple and they replaced both fans & a memory module20:53

awenew issues are on my new macbook, and appeared as soon as i updated to -720:53
awei also noticed an nvdia update at the same time...20:53

rtg_awe, nvidia shouldn't affect the boot to grub20:55

Q-FUNKone question about karmic:   was there any change in network modules that could explain why an host with an IPv6 address could be pinged under jaunty but not karmic?21:45
rtg_Q-FUNK, they are 3 full kernel versions different, 2.6.28 v.s. 2.6.31. Maybe you could use some of the mainline builds to find out when things quit working.21:47
Q-FUNKI'm still using 2.6.28 on that host.  2.6.31 won't boot (bug filed, ogasawara is working on it) and 2.6.30 are gone from the karmic repo.21:48
rtg_Q-FUNK, look in http://kernel.ubuntu.com/kernel-ppa for maniline builds21:49
Q-FUNKhowever, I thought that maybe some newer version of e.g. ufw might load network modules that it didn't in jaunty or something similar21:49
rtg_you could talk to jdstrand about ufw21:50
Q-FUNKrtg_: I cannot think of anything different in the network config I use on my karmic and jaunty hosts either, yet the only host that cannot be ping'ed with 'mtr' is my karmic host.22:00
rtg_Q-FUNK, get a bug started so we don't forget it. gotta go.22:01
Q-FUNKI'd love to but, at this point, I'm not even sure if it's kernel related22:03
