ln-Package: linux-image-2.6.15-51-68600:01
ln-Version: 2.6.15-51.6400:01
BenCthat's not the one with the fix00:01
BenCit was fixed in 51.6500:01
BenCmake sure you have all the latest updates from dapper-security00:01
BenCreboot, and retest00:01
ln-i do have all the updates from dapper-security...00:02
BenCeither you're mistaken, or that upload has not been released yet...either way, you aren't testing the version that has the fix00:05
BenCI'm checking the upload status, give me a minute00:05
ln-thanks00:05
=== reynaldo_ is now known as reynaldo
BenCln-: looks like that upload is pending00:09
BenCln-: kees would know more00:09
ln-do you think there's something wrong in ubuntu's "process," if a thing broken in Oct 2006 doesn't get fixed by Feb 2008, even if the fix is known and is trivial?00:13
BenCln-: considering there's a work around and there is no data-loss involved, it's a rather trivial issue to begin with00:15
BenCln-: kees handles security, so you really should talk to him00:15
=== doko_ is now known as doko
ln-i'll try to ping him again tomorrow.00:16
ln-... or why bother.00:25
BenCln-: well, if there's is an issue with the process, kees would be willing to explain or possibly improve00:27
BenCln-: I'm sure he would appreciate input, or being put on the spot :)00:27
ln-ok, i'll ping him then..00:28

Kanohi, current aufs in lum works for me09:13
Kanobut09:13
Kanowith standard ubuntu config (too many old legacy drivers) i get this09:15
Kanohttp://paste.debian.net/4803309:15
Kanowhich results in no dma for hdc09:15
Kanoa pure libata kernel has no problem at all with it...09:16
Kanoalso, i see no reason to try blacklists on those 2 modules, debian has even bcm43xx completely disabled, you could do that too09:18
Kanohttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/18571909:18
ubotuLaunchpad bug 185719 in linux "remove duplicate pci ids bcm43xx/ssb prism54/p54pci" [Medium,Triaged] 09:18
Kanoas soon as tools like discover are installed blacklisting does not work09:18
Kanohostap_pci is completely unstable btw. dont know why09:19
Kanop54pci works fine09:19
Kanodid anybody try ath5k?09:26
lagahey juliank 10:16
lagajuliank: aufs doesn't work with nfs branches. it was complaining that i need to apply the lhash patch (and add the config option)10:17
julianklaga: Are you running the latest git kernel?10:18
Kanohi laga , well it worked for live mode, but you can add those ;)10:18
lagajuliank: "latest" as in "pulled right after rtg committed your patches", yes.10:19
lagaKano: great :)10:19
Kanodid you get the link in pm?10:19
lagayes10:19
Kanoit has some problems shutting down, but before i got kde boot errors10:20
lagahaven't tried it yet, i don't need live disks at the moment :) 10:20
lagaoh10:20
Kanoyou can use vbox or vmware to boot it too10:20
julianklaga: the latest ubuntu-hardy.git +  ubuntu-hardy-lum.git should work10:20
Kanoyou will see a huge difference when you boot with union=unionfs 10:20
lagaKano: speed-wise?10:20
Kanothen network-manager does not work10:20
Kanoi dont get why the same kernel works on hardy with networkmanager10:21
Kanowith unionfs10:21
Kanomaybe somebody changed networkmanager10:23
lagamy nick comes up #2 in google when you search for "unionfs sucks", so don't expect an answer from me10:23
Kanogood point ;)10:24
laganote: i've changed my opinion since then. current unionfs is probably just fine with a vanilla kernel, but i guess i'll never find out :)10:25
Kanowell not for me, with the test i did...10:25
lagajuliank: the changes which have been committed since then are not relevant - except for the missing entries in debian/config/i386 which i added myself10:27
Kanoi even had the strange issue with unionfs that in a vm a simple du -h /dir returned an error - a real pc did not have that error however10:28
lagaodd.10:28
julianklaga: do cat /sys/fs/aufs/config10:28
lagaunionfs doesn't work well with bonnie either. not sure what's causing that.10:28
Kanocould never trace it why this happend, aufs worked10:28
julianklaga: what does not work? build or mount?10:31
lagajuliank: mounting. 10:31
lagajuliank: i'm booting the VM now..10:31
Kanoit builds, thats not the problem10:31
Kanodo you want a sample iso?10:31
juliankKano: You have an ISO?10:32
Kanoof course10:32
juliankKano: size?10:32
Kanowith that kernel, but based on etch10:32
Kanolive-helper created10:32
Kanountil some other things are patched in u i will not use it10:32
lagajuliank: CONFIG_AUFS=m, CONFIG_AUFS_FAKE_DM=y, CONFIG_AUFS_BRANCH_MAX_127=y, CONFIG_AUFS_SYSAUFS=y, CONFIG_AUFS_RR_SQUASHFS=y10:33
lagajuliank: that's /sys/fs/aufs/config10:33
lagaif fails with the error message: aufs test_add:357:exe[2033]: NFS branch is not supported, try some configurations and patches included in aufs source CVS10:35
julianklaga: I'm fixing it.10:35
lagajuliank: great.10:36
Kanowell you would need to patch+compile the kernel first to try10:36
lagapatch what?10:37
juliankKano: The Ubuntu kernel has the patches.10:37
Kanojuliank: fine, then it should be easy to update just lum10:38
Kanoa few seconds ;)10:38
juliankKano: One variable name is wrong, that's all.10:39
Kanogood, can update lum with ease10:40
Kanoscripted ;)10:40
julianklaga: Do you have a build log of l-u-m?10:40
lagajuliank: no, but i can make one real quick :)10:41
julianklaga: I'm building10:41
julianklaga: try to add KSRC=$(PWD) to the top of ubuntu/fs/aufs/Makefile and build it.10:43
Kanoalso could you enable aufs for powerpc too?10:43
julianklaga: I will send a patch soon10:43
juliankKano: Soon.10:44
Kanodid somebody have got no framebuffer support on amd64 live cd or is it just me?10:46
Kanoi386 live cd has a splash10:47
Kanoamd64 not10:47
Kanojuliank: what do you think about a blacklist option for casper, i have that for kanotix10:48
Kanoit writes to /etc/modprobe.d/custom-blacklist10:48
Kanobefore udev starts10:48
lagajuliank: i don't think it's working10:52
lagasame message10:52
julianklaga: I need a build log.10:52
lagajuliank: http://www.pastebin.ca/88445610:54
lagajuliank: here's the KSRC patch i added: http://www.pastebin.ca/88445710:55
julianklaga: rebuild with KSRC=$(srctree)10:57
lagaam i supposed to use that string literally or should i expand srctree?10:58
julianklaga: as written. it's a variable10:59
lagaoops. that's gonna take a few minutes, just deleted the squashfs image for my diskless client.11:05
lagajuliank: ok. CONFIG_AUFS_LHASH_PATCH and friends were picked up properly, but i'm still getting that error message. 11:12
lagajuliank: ok. CONFIG_AUFS_LHASH_PATCH and friends were picked up properly, but i'm still getting that error message. 11:12

lagai left out the CONFIG_ part. 11:15
lagajuliank: what do you need grepped?11:17
julianklaga: not needed. I know the problem now.11:17
lagajuliank: great11:17
julianklaga:  the patch is at http://www.pastebin.ca/884477 -11:19
lagathanks, building now11:24
lagajuliank: awesome, it's working.11:29
julianklaga: I'll send the patches to kernel-team11:29
lagajuliank: great11:29
julianklaga: patches sent11:33
laga:)11:33
lagait takes 27s from power-on to having X loaded with aufs in my diskless environment11:34
lagathat's very nice IMHO :)11:34
julianklaga: Could you try to use the rr flag for the nfs root? I need to know if this works.11:34
julianklaga: in the aufs mount options11:35
lagajuliank: i'm not using nfs root, i'm using a squashfs root with a nfs share on top. still want it?11:35
julianklaga: your nfs root is specified in dirs= or br=, then yes11:36
julianklaga: s/root/share/11:37
lagaok11:37
juliankI always kill my ssh proxy because I close the window ssh is running in.11:39
lagajuliank: well.. aufs does not fail, but of coruse the system won't boot because / is read-only :)11:40
julianklaga: that's good.11:41
juliankthanks11:41
juliankexit11:41
Kanolaga: how about exporting it again via nfs and boot via network?12:20

Kanortg: hi, didnt you say you remove the pci ids when i report the bug?19:14
lagaKano: i think if you increase the frequency of your questions it'll get fixed faster19:32
Kanortg: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/18571919:36
ubotuLaunchpad bug 185719 in linux "remove duplicate pci ids bcm43xx/ssb prism54/p54pci" [Medium,Triaged] 19:36
Kanoi dislike that idea with blacklisting19:37
Kanolaga: best tell him that this change is needed, also you could forget the bcm43xx patch when you disable that module (same for prism54), debian disabled bcm43xx19:55
Kanobye19:56
rtglaga: so what does Kano think is wrong with blacklisting? 19:59
lagai have no clue20:03
lagain that ticket, he says that it'd break if "discover" was installed20:03

amitk_rtg: what version of ALSA is in the stock kernel?22:25
rtgamitk_: dunno, some mix of 1.0.15 plus. I've removed it from the kernel for -6.10 and put it in lum (1.0.16rc2)22:26
amitk_rtg: aaah...22:28
amitk_rtg: are we updating to a newer version of alsa in lum?22:28
rtgamitk_: is that the sound of something stuck in your throat ? :)22:28
amitk_hehe22:29
rtgamitk_: I pulled ALSA this AM, so the version in lum is very current.22:29
rtgIts actually -rc2 plus 8 or 9 more patches.22:29
rtgamitk_: by the way, I'm still build testing... You mileage may vary.22:30
crimsunJaroslav (employed by Red Hat now) anticipates releasing 1.0.16 final next Tuesday.22:33
