crazybytejjohansen, hello! may i get on your nerves for a short time?07:56
jjohansencrazybyte: sure07:57
crazybytethanks :)07:57
crazybytewell, could you suggest where to try to submit bug report or send a mail got get some pointers on the bug i submitted. to be honest it starts to piss me off. If I use the karmic kernel is oopses even before resume if I use the lucid kernel it oopses only after resume but I can't be sure about that08:00
crazybyteif i try to compile a kernel or try another distro would possibly solve the issue? could this be due to some ubuntu patches or it's a general issue from what you know?08:02
crazybytejjohansen, could it be that the APIC is reenabled on resume and causes the oopses (due to something) ?08:04
jjohansencrazybyte: it sounds like a general issue but trying another kernel might solve it08:04
jjohansencrazybyte: no, it is likely broken bios not setting something correctly08:04
jjohansencrazybyte: from a terminal type ubuntu-bug linux08:05
jjohansenthat will run through the apport hooks to open a kernel bug, file it against lucid08:05
crazybytejjohansen, yeah. like i said some time ago. i had issues with the bios but they were solved from what i see in the newest kernels but instead of that issue now i have this which is most disturbing08:05
crazybytejjohansen, in most cases the only thing i can do is to force reboot using magic key08:06
jjohansenhrmm, wait, don't open a new bug :)08:06
crazybytebecause after that oops a chain of oopses follow08:06
jjohansenright08:06
crazybytei have the bug already in launchpad08:06
jjohansenyeah, sorry I was thinking about something else08:07
crazybyteno problem. i also tried disabling the smp thinking that the bug is related to what i had in hardy, but without any luck it died after a few resumes08:07
jjohansencrazybyte: you have the lp bug # handy08:09
crazybyteone sec08:09
crazybytejjohansen, 56517208:09
crazybytejjohansen, i will try a vanilla kernel tonight and see what happens. the kernels from kernel.ubuntu.com are vanilla or they have already the ubuntu patches applied?08:13
jjohansencrazybyte: ubuntu patches, but we have a mainline build ppa08:14
jjohansenhttps://wiki.ubuntu.com/KernelTeam/MainlineBuilds08:14
jjohansenhttp://kernel.ubuntu.com/~kernel-ppa/mainline/08:14
crazybytei see08:15
crazybyteok08:15
crazybytethank you!08:15
jjohansennp08:15
crazybyte i will try and come back later08:15
jjohansenokay08:15
crazybytejjohansen, btw the addresses i mentioned where the kernel paging fails are the used by user applications.08:16
crazybytethey are not used by the kernel or some modules (you remember i asked how to find out what is using those addresses)08:16
crazybyteok08:16
crazybytesee you later (or annoy you later if i may joke about it)08:17
crazybytethanks again08:17
jjohansencrazybyte: right, that is interesting I'll look through the bug again and refresh my memory08:17
crazybyteok08:17
crazybytethanks08:17
Kanohi apw , could you commit this10:13
Kanohttp://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d1501ea844eefdf925f6b711875b4b2b928fddf810:13
Kanowill be in 2.6.32.12 anyway10:13
apwKano, we'll be pulling in the stable update shortly after release i would think10:17
Kanowell .12 is not out ,but that little commit will not hurt, it just fixes one laptop10:18
Kanotested from .32 to .3410:19
Kanomaybe even older kernels possible, just not tested10:19
apwwelll the kernel won't change before then anyhow10:22
Kanodoes not matter, i use git10:22
Kanoi patch it currently on my own10:22
Kanoi still dont get why you never commited http://kanotix.com/files/kernel/unused-patches/2.6.30-ubuntu-copy-ieee1394-header-for-dvb.patch10:24
Kanobecause without those headers you never can compilie full dvb drivers from external sources, you have to disable firewire drivers all the time10:25
aboganiKano: I'm just curious: DO you have already sent that patch upstream?10:28
Kanoabogani: i mentioned it definitely here when i began to compile my own kernels with it. i just hate to repeat myself all the time.10:30
aboganiKano: Ok, sorry.10:31

hyperairMTecknology: well they'd know more about initrds, in any case =D19:45
MTecknologyI'm booting without any initrd. So initramfs-tools seems pretty pointless. Is there any reason that seemingly half the packages in the system have a dependency on it?19:45
MTecknologyhyperair: btw.. The number one complaint I've heard about Ubuntu is that we 'take away choice' I'm on a personal mission to rip that theory to shreds. I could go repackage each one of those packages and check out the code and the Depends: and change to Suggests: or go about it other wasy. But I'd rather see it there are better options19:48

rackerhacker2.6.32.9 works acceptably, but ureadahead & plymouth throw out some interesting errors at boot22:25

rackerhackeralrighty, well it seems to work ;)22:28
rackerhackeri wasn't sure if y'all had tossed it on ec2 yet22:28
jjohansenwhat are the errors you are seeing with ureadahead and plymouth?22:28
jjohansenI haven't loooked at that at all recently, but last I remember we were going to disable ureadahead for virtual installs, because the ureadahead buffer can be as large as the vms memory22:30

rackerhackermy knowledge of ureadahead is relatively limited22:54
jjohansenrackerhacker: alright I'll need to poke some as I didn't do the changes for ureadahead and plymouth, but those error messages are likely to be how ureadahead is being "disabled"22:55
rackerhackerno rush as it appears to be cosmetic at this time22:55
rackerhackerif you want an environment to play around with, give me a shout and you'll get one22:55
rackerhackeri'll be in california for the xen summit for the rest of the week, but i'll check my email pretty often22:56
jjohansenbasically, since ureadahead uses a large kernel ftrace buffer small memory vm's where running out of memory and couldn't boot22:56
rackerhackerlet me see if it happens on a bigger instance22:56
rackerhackeryeah, exact same output on a 2GB i386 lucid install22:58
