fabbioneok...06:22
fabbionewas that with or without options?06:22
fabbioneyou could also try to add: pci=routeirq06:23
pooliethat was 9, which is currently installed, with nosmp noreplacement06:23
pooliedo you want me to try the dvd, or the installed image with those options?06:24
fabbionebefore you change kernel, please try to add pci=routeirq too06:25
fabbionethen jump to 2.6.20-10 or -1106:25
fabbione(not sure -11 has been uploaded yet)06:25
fabbionestart without options06:25
fabbioneand add them one at a time to see which one changes behavioy06:25
fabbionebehaviour06:26
fabbionei suggest you also take note of these tests and add the results to the bug06:26

pooliefabbione: hi, still no luck with the current -1009:00
fabbionepoolie: did you try all the options*?09:00
pooliefabbione: where do the device files come from in initramfs? i have no sda109:00
pooliejust going to try pci=routeirq09:01
fabbionepoolie: they are generated by udev09:01
fabbioneand there is a bug about it09:01
poolieok, it also oopses with pci=noroute added09:04
pooliebut i also get, earlier, mdadm: No devices listed in conf file were found. / failed to assemble all arrays 09:05
pooliewhich i guess is why it can't mount root, which is on raid09:05
\shfabbione: do you know anyone from HP who is an ubuntu geek, best location uk or europe in general? :)09:07
fabbionepoolie: cat /proc/partitons .. does it show the devices?09:07
poolieit's empty09:08
fabbione\sh: try one of our sysadmins...09:08
fabbionepoolie: ok if that's empty there is no way to assemble a raid out of thin air... it means that disks have not been found at all09:08
poolieright09:08
\shfabbione: elmo or znarl?09:08
fabbioneand that's mostlikely related to the block subsystem OOPSing09:08

poolieok, will take a while to come back up09:14
lifelesspoolie: you could also try setting root= during the boot09:14
poolieto what?09:15
poolieoh i see09:15
pooliewhile booting from cd 09:15
poolieyep worth a shot09:15
pooliei wonder why the recovery mode needs you to set a hostname?09:22
poolieoh ffs09:39
fabbioneBenC: that linker script error seems to show up only when forking the build with CONCURRENCY_LEVEL09:43
poolielifeless: i'm chrooted into my root from the installer kernel, what did you want me to try?09:47
lifelesswell you should be able to upgrade your kernel, udev, now09:55
poolieyeah, that's what i did09:56
poolieso the good news is i have a way to get updates on; but they don't fix it yet09:56
lifelessok09:56
lifelessso the installer has the same kernel as you now, and udev. So it might be another package09:56
pooliewell, the installer actually uses -9, which is quite a bit older the current one in the distro09:57
poolieor it may be starting things up in a different order from userspace that avoids this09:58
pooliebut for now i will wait for guidance from benc i think09:58
Mithrandirpoolie: try installing -9 from the repositories and see if that boots correctly?09:59
pooliei have, though maybe they updated -9?10:01
pooliedo you know when it gets a new -9 number rather than a -9.1?10:01
lifelessyes10:03
lifelessthe -X is the ubuntu serial number for all intents and purposes10:03
Mithrandirpoolie: grab the correct set of binaries off https://beta.launchpad.net/ubuntu/+source/linux-source-2.6.20 ?10:03
=== Lure [n=lure@external-7.hermes.si] has joined #ubuntu-kernel
poolielifeless: but sometimes there are several uploads of -9?10:04
poolieMithrandir: will that be different to what's in the archive?10:05
Mithrandirpoolie: if you grab the one marked "removed", yes.10:05
Mithrandirpoolie: -9 is the ABI version, it's only bumped when the upload changes the ABI.10:06
Mithrandirthere was two uploads of -910:06
pooliei see, thanks 10:06
poolieMithrandir: and which do you think is correct?10:07
poolieit's broken in -7; it's broken in -1010:07
Mithrandir2.6.20-9.16, probably.10:08
poolieok, and you think that might work because it's the one used by the installer?10:10
Mithrandiryes10:10
poolieok thanks10:10

aboganiMithrandir: May i disturb you?03:31
Mithrandirabogani: sure, what's up?03:55
aboganiMithrandir: About my spec (https://wiki.ubuntu.com/RealTime)....03:56
aboganiI have created a linux-patch-realtime-preempt package. This package contain only the Ingo Molnar's patch (and not all linux kernel source) adapted to Ubuntu linux kernel (i use dh-kpathes method). Users can build kernel follow this http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-getting     03:56
aboganiIt is a right way? Now exist a possibility that this package will be accepted in universe? What i should do for achieve this objective?03:57
BenCabogani: get someone to review it, and sponsor the upload, then buy Mith a few pints04:04
BenCabogani: That's something you'd want to check #ubuntu-motu for04:05
Mithrandirabogani: your approach seems sane, yes.04:07
aboganiBenC, Mithrandir : Ok Thanks :-)04:07
BenCabogani: and if it helps, I'll give a nod for the package, considering you were very open to packaging suggestions and quick to change the entire build process to suit it04:09
Amaranthwouldn't it be better to do like Xen and have the package pull in the kernel source, apply the patch, and build a kernel for the binary package?04:10
BenCAmaranth: That's what he did04:10
Amaranthoh, i thought he was saying the end user would have to build the kernel04:10
BenCoh, maybe he did, I misread04:10
BenCI suggested using the xen method yesterday :)04:10
=== mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-kernel
aboganiBenC: I already seen Xen packaging approach.. but xen-source package contains a complete linux source copy! It is also _vanilla_ kernel! ...... Ok i'm confused. :-| .... What is exactly the xen package that i should use as example?04:33
BenCabogani: The 2.6.17 one in edgy04:34
BenCthe one in feisty might be full source04:34
aboganiBenC: Ahhhh04:34
Mithrandiruh, please don't do that.  It's deprecated and I will reject any new packages doing that.04:35
Mithrandiryou're free to have a package that build-depends on the appropriate kernel source, includes a patch and builds linux-image-$whatever binaries, though04:36
aboganiBenC: thank you for the patience :-)04:36
BenCMithrandir: that's the approach he's working towards04:37
