reiseippisati: yep07:42
ppisatireisei: btw, it's panicing on the shutdown, nut much we can do07:42
ppisatireisei: btw, we do you use the linaro kernel instead of the ubuntu one?07:42
ppisati*why07:42
reiseippisati: because I use specific board. Developer use linaro, so should I.07:43
ppisatireisei: than i'm sorry, can't help you07:45
ppisatireisei: which kerne are you running?07:45
ppisatireisei: i mean, version?07:45
reiseippisati: 3.1.507:47
ppisatireisei: why don't you try with 3.3.?07:47
reiseippisati: I can compare... but have to port board file whatever07:50
ppisatireisei: did you try without the omapdrm module? or you need it?07:52
reiseippisati: 3.1.5 is stable enough, but there is this annoying halt issue07:53

apwdileks, erm, we don't normally before A1 but i haven't checked we may have not stopped09:47
dileksI wanted to test a "remastered" iso - before answering your email09:48
apwdileks, its not an easy game changing the kernel in the iso ...09:48
dileksas this is why I primarily need/want overlayfs09:49
dilekshmm, lets see. if it fails I will test with live-build09:49

akgranerbjf, yep - I "borrowed" it from Pete - before I knew it belonged to you - is it ok if I use it during UDS then give it back to you then?13:38
bjfakgraner: sure13:39
bjfakgraner: i was not using it at all, so have fun with it13:39
akgranerbjf - thanks a million - I needed an older one  - it will be running one of the summit displays at UDS :-)  thanks for your contribution to the cause.13:40
akgranerbut I'll package it all back up nice and neat for you on Friday13:40

dileksa question to bind-mounts14:19
dilekssudo mount --bind /run $CUSTOM_DIR/run14:20
dileksthat should cover /run /run/shm and /run/lock14:20
dilekssudo mount --bind /dev $CUSTOM_DIR/dev14:20
dilekssudo mount --bind /dev/pts $CUSTOM_DIR/dev/pts14:20
dileksisnt 1st line enough?14:20
jsalisburytgardner, I'll help bisect that one14:20
apwdileks, i'd expect the bind mount to only bind each filesystem, so pts is another mount and needs binding separatly14:21
dilekshmm14:22
dileksand for the /run/* stuff the same?14:22
dileksDo some bind-mounts before entering chroot-env: http://nopaste.snit.ch/13742714:26

htorquehope it's okay to ask in here: why is the kernel debug package (-dbgsym) a 650 mb download, when in debian it's just 250 mb?17:30
dilekshtorque: IIRC waldi switched to xz for compressing which reduced -dbg packages immensly. dunno what ubuntu-kernel uses.17:46
htorquedileks: yeah, that would make sense i guess. they also differ in on-disk size, though 2.2 gb vs. 1.8 gb. (not that i expect them to be exactly the same, of course.)17:48

smoseranyone know what kernel options i need to add to make kms never switch modes ?  ie "old school vga"18:47
hertonsmoser, nomodeset I think is what you want18:50
smoserherton, thank you.  i swear at one point in the past i had to even blacklist some kernel modules, but.... thanks.18:52

jsalisburytgardner, thanks.  Yeah, these wireless bugs have so many variables that come into play.19:23
tgardnerjsalisbury, at least its not systemic.19:23

dileksafter deinstalling (live-boot and) live-boot-initramfs-tools, I can boot my own 3.4-rc5 kernels19:27
dilekswhats live-boot-initramfs-tools modifying on kernel-installation?19:28
dileksfs-problems and swap cant be mounted (ignore - modify - manual repair)19:29
ogra_ubuntu doesnt use live-boot anywhere ... but i would assume it does similar things casper does 19:29
ogra_(mounting a squashfs image into an overlayfs or aufs mount to achieve a writable rootfs from an iso)19:30
dileksogra_: it seems to have some kernel hook-scripts19:33
dileksI see that when doing dpkg -i $linux-image-file19:33
ogra_well, it surely havily modifies the initrd like casper does19:33
dileksthats breaking my kernels build with make deb-pkg19:33
ogra_right, why do you install a tool to boot live isos in your build env ?19:34
dileksI wanted to create an own live-system and was experimenting on my host19:35
ogra_well, dont do that :) 19:35
ogra_roll your live images iside a chroot 19:35
ogra_*inside19:35
dileksyupp, know I am wiser19:35
dilekstoday I experimented with re-packing a precise-iso19:36
dileksso refreshing chroot skillz was one lesson19:37
dileksogra_: http://paste.ubuntu.com/965367/19:37
ogra_looks fine on first sight19:39
dileksbut the goal was to include a selfmade linux-image or one from mainline19:41
dileksI guess I have to hack that *.lz file 19:41
tgardnerapw, can't seem to get this nVidia hang to repro after all this futzing about.19:42
ckingtgardner, sounds like a typical hardware enablement scenario - use lots of time up getting no-where :-/19:47
tgardnercking, indeed19:47
