\shwhich script generates the initrd for the linux-image package in postinstall? I don't see it in debian/* of linux-source-*, could be that I'm blind ;)12:50

\shyes...I see it now ;) make-kpkg generates postinst12:58
cjwatsonBenC: https://launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/76341 is quite a nasty issue. Do you think you/kyle could have a look at it with the lkml reference I gave?01:51
=== ivoks [n=ivoks@backup.grad.hr] has joined #ubuntu-kernel
BenCcjwatson: sure02:17
BenCcjwatson: Ah, I talked to Keybuk about this, and I'm not sure we've concluded whether it was a udev or a kernel bug02:17
BenCthe kernel code hasn't changed02:17
cjwatsonthe lkml thread seemed to reckon that it was a kernel bug due to MODALIAS=i8236502:18
cjwatsonbut I couldn't find anything outside that thread02:19
cjwatsonI tried to work around it in udev rules, but haven't succeeded yet02:19

zulhey02:41
jes-o-matBenC: yes and I was using the commands as written02:41
BenCjes-o-mat: Without some context, I can't give you any more info02:42
jes-o-matbut there are a lot files missing in kylem's git tree02:42
BenCLike what files02:42
jes-o-matbasic things like copyright e.g.02:43
BenCwhat git tree are you using?02:43
jes-o-matI have taken some of them from the linux-source package, but now I got to a point where the build scripts needs some debian/d-i/shared/firmware/* files which are not present02:44

BenCshows the copyright file, and others02:49
BenCmust be your lock tree02:49
BenCs/lock/local/02:50
jes-o-matI used the following to fetch the tree:  git clone rsync://rsync.kernel.org/pub/scm/linux/kernel/git/kyle/ubuntu-dapper-updates.git ubuntu-dapper-updates02:51
BenCAll I know is, the tree on kernel.org is fine...not sure why yours is having problems02:55
BenCgit-checkout -f02:55
BenCsee if that helps02:55
jes-o-matini get a lot of "unable to read sha1 file of ..."02:56
jes-o-matmaybe the argument "ubuntu-dapper-updates02:56
jes-o-mat" is false02:56
jes-o-matI just guessed it02:56
jes-o-matcuase the wiki is only talking about linux-2.602:57
jes-o-matoh02:57
jes-o-matthat's for the local directory :)02:57
BenCjes-o-mat: my guess is that git isn't following the alternative objects to my tree02:59
BenCjes-o-mat: Best bet is to clone my tree, then pull from kyle's02:59
kylemit probably doesn't if you use rsync.02:59
kylemuse git://02:59
BenCjes-o-mat: Telling me about the missing sha1 messages would have been helpful before :)03:00
jes-o-matBenC, kylem: I'll try using git://03:03
jes-o-matBenC: the list was *very* long :)03:03
kylemjes-o-mat, my repository shares objects with ben's so that it doesn't take a long time to mirror. the downside is you need to use a git-aware protocol for fetching it.03:04
jes-o-matkylem: is the host still rsync.kernel.org?03:04
jes-o-mator is there some git.k.o host?03:05
kylemit's the same pair of machines either way03:05
kylema CNAME by any other name would resolve as sweet.03:05
tepsipakkikylem: I see the upload to dapper-proposed as rejected?03:06
jes-o-matsweet CNAME ... I need to remember that :)03:06
kylemtepsipakki, one of them was rejected, there were two.03:06

tepsipakkikylem: I've searched the dapper queues and I can see only the rejected one :)03:10
kylempossibly one of the archive folks needs to be cattle proded.03:10

jes-o-mat*grml* git:// is blocked by firewall03:15
Mithrandirjes-o-mat: ssh -D 1234 wherever, then use tsocks on localhost:123403:16
Mithrandirssh -D is like the best invention since the internet.03:17
jes-o-matMithrandir: great! didn't knew the -D flag - I always had used -L or -R03:19
kylemMithrandir, hah.03:19
zuli thought slice bread was a pretty good invention myself03:19
Mithrandirsliced bread is a _horrible_ invention.03:21
zuli disagree03:24
kylemi hate sliced bread.03:27
kylemi much prefer carving out a quadrant of a nice big loaf of pumpernickle03:28
thomi am lazy. all dutch bread is horrific, so it makes no odds to me03:30

thomMithrandir: see my leading sentence03:31
Mithrandirthom: bread making machine.03:31
Mithrandirpour ingredients, set timer, wake up to a fresh loaf of bread.03:31

jes-o-matkylem: seem that the changes does not solve #37452 :/04:49
jes-o-mateverything compiled well but after creating the hw-raid the kernel cannot access sda04:50
kylemwell, someone who actually has the hw will have to hunt down the changeset which fixes it. i can't test it.04:52
cjwatsonBenC: did /proc/cpuinfo change on i386/amd64 recently (.20) for multiprocessor machines? I see why bug 79109 is happening, but apparently it didn't happen with Herd 1 and the relevant code in base-installer hasn't changed at all05:02
BenCbug #7910905:02
BenCcjwatson: It's possible, what portion is it using?05:03
BenCcjwatson: diff'ing the cpuinfo from my 2.6.20 coreduo and 2.6.17 core2duo doesn't show anything changing other than values of the cpu itself05:05
BenCI can try a boot into 2.6.20 for the core2duo and see about same cpu changes05:06
BenCcjwatson: The only thing I see different is that in 2.6.20 it recognizes the difference between physical cpu's and cores05:14
BenCso on .17 it would show physical_id={0,1} and core_id=0 for the two, and on .20 it shows physical_id=0 and core_id={0,1}05:15
cjwatsonBenC: it's grepping for 'cpu family' lines, and forgot to do head -n105:15
cjwatsonBenC: if older kernels had only one cpu family line, but current ones have two (which current ones do), then that would explain it05:16
BenCI show two lines in both05:17
BenCso that didn't change05:17
BenCdoes it use siblings?05:17
BenCor "cpu cores"?05:18
cjwatson        FAMILY=`grep '^cpu family' "$CPUINFO" | cut -d: -f2`05:18
cjwatson        case "$VENDOR" in05:18
cjwatson                " AuthenticAMD"*)05:18
cjwatson                        case "$FAMILY" in05:18
cjwatson                                " 6"|" 15")     echo k7 ;;05:18
cjwatsonjust that sort of thing05:18
cjwatsondunno, maybe it was always broken - I was just curious05:19
cjwatsonoh, unless vendor_id changed similarly - it greps for that too05:19
cjwatsonnothing else, not siblings or cpu cores05:20
BenCstill shows GenuineIntel05:20
BenCOn i386 and amd64 there shouldn't any of this anyway05:21
BenCit should always install -generic05:21
cjwatson-generic is built for 586, so it's needed for 486 systems05:22
cjwatsonmost of the code is inherited, but still05:22
BenCtrue, -386 is the side case05:23
cjwatsonon amd64, in practice it makes no difference - it installs -generic regardless05:23
cjwatsonit's not vendor_id contents I'm thinking about, but whether it appears once or twice05:23
jes-o-matkylem: I just digged into the source and the suggested patchset from Cedric Schieli did not made it into your git05:23
BenCit appears twice on .17 and .2005:24
cjwatsonanyhow, I have a fix now05:24
cjwatsonok, thanks05:24
BenCcjwatson: Do you want my cpuinfo's for reference?05:24
BenCcjwatson: emailed, can't hurt to have it05:25
cjwatsonsure, thanks05:27
cjwatsonBenC: ah, fjp pointed me in the direction of the answer - between Herd 1 and 2, we switched the installer from 386 to generic, and 386 doesn't have SMP alt so the second core didn't show up in cpuinfo05:38
kylemjes-o-mat, which kernel image do you need?05:42
jes-o-matkylem: -server05:43
kylemamd64 or i386?05:43
jes-o-mati386 (for now)05:44
kylemalright05:45
=== kkubasik [n=kjk38@kjk38-laptop.STUDENT.CWRU.Edu] has left #ubuntu-kernel []
BenCcjwatson: The d-i installer, or the livecd installer?05:53
BenCI thought the installer for the alt CD was going to remain 38605:53
cjwatsonfor edgy, it did, but I elected to change that for feisty and just retain the netboot install as 38605:54
cjwatsonI think I mentioned that possibility in mail to you pre-edgy05:54
cjwatsonit simplifies the desktop seed rather a lot, because we can just slam linux-headers-generic in there and not worry about which installer is in use05:55
BenCso the bug was always there, it just never showed up because the -386 installer didn't see the extra cpu's?05:55
cjwatsonhttps://lists.ubuntu.com/archives/ubuntu-devel/2006-December/023036.html05:55
cjwatsonright05:55
cjwatsonI should probably have CCed you on that mail about the installer change05:55
BenCwell, the cpu checking is still pretty moot, because if they boot the live or alt cd's, they don't need -386 anyway05:57
BenCbut it certainly can't hurt to have it, since the end result is the same :)05:57
cjwatsonthat's true, but the same code is used for the netboot installer where it might conceivably matter05:58
cjwatsonI realise it's all a tiny corner case - I just prefer fixing mostly-working code over removing it :)05:59
