jbaileyWow, really musn't leave this long between merges of initramfs-tools02:26
zuloh dear i have the hiccups02:26
jbaileyThe merged version only has 908 lines of diff now.  *sigh*02:27
zulonly?02:28
Keybukheh02:28
Keybukthat's quite an improvement02:28
Keybukwhat are the major changes?  did we take the /etc/mkinitramfs => initramfs-tools change?02:29
jbaileyYup02:29
=== nigel_c [n=nigel@nigel.suspend2.net] has joined #ubuntu-kernel
jbaileyAlot of it was that they went through and cleaned up quoting.02:29
jbaileyWe pushed hook scripts out to various packages.02:29
jbailey(I've taken all of the quoting changes now.  yay debdiff)02:30
Keybukcool02:32
jbaileyAlot of the stuff that's in the Debian version is actually things from us.02:33
jbaileySo while there would be subtle things like quoting changes.02:34
jbaileyOr places where tab/8 spaces was different, they code was the same.02:34
Keybukok, so we shouldn't expect much to change?02:34
jbaileyRight.02:34
jbaileyThere's a new noresume feature.02:35
jbaileyAnd whee, the machine booted fine.02:35

=== jbailey reviews the ubuntu-old to ubuntu-new debdiff.
jbaileyKeybuk: An interesting change is that rather than doing touch /dev/.initramfs-tools, it now does > /dev/.initramfs-tools02:39
BenCkernel-package uploaded aswell02:39
jbaileySo you can always fetch more info from there.02:39
jbaileyAlso, it fixes the ramdisk size for /dev at 10M02:39
jbaileyAdds cryptroot support02:40
jbaileyApparently works with lilo better now.02:42
BenCzul: I'd be interested to know if the new kernel-package handles your xen stuff well02:42
BenCzul: I can send you a .deb if you need it02:42
zulBenC: it doesnt work that great with the patch that we had, it didnt make the vmlinuz and when i tried making the kernel-image it wanted to make linux-xen002:43
zuldebian doesnt use kernel-package for the xen0 kernels02:43
zulother than that i been doing make and make install for the modules and vmlinuz02:44
jbaileywhee, accepted.02:46
jbaileyOff to spend the rest of the evening with my wife and sister-in-law.02:46
zulif the kernel-package sees CONFIG_XEN then it wants to build the linux-xen0 image02:47
BenCzul: I didn't port the xen stuff, just relying on the support already in kernel-package 10.x02:49
zulBenC: i know :)02:49
BenCyou could just install the debian kernel-package, and for xen, it should be same02:49
BenCok :)02:49
zultrue...i havent tried the kernel-package since 02:50
DarkMageZcan anyone confirm if r8169 exists in dapper's k7-26?02:50
crimsun/lib/modules/2.6.15-26-686/kernel/drivers/net/r8169.ko02:52
crimsunI don't see why -k7 would differ.02:52
cjblikewise /lib/modules/2.6.15-23-k7/kernel/drivers/net/r8169.ko02:53
cjb(which is k7 but not 26.)02:53
DarkMageZyeah, i did test the box against -23 (which it still has hanging around). hmm, i'll have to do more testing when i get back to work... thanks02:55
crimsun-rw-r--r-- root/root     37174 2006-07-07 14:24 ./lib/modules/2.6.15-26-k7/kernel/drivers/net/r8169.ko02:56
DarkMageZyeah, i brought one of those cards yesterday and it just didn't work. i'll check over for me making noob mistakes and try again :) cyas02:57
cjbSpeaking of this stuff, is there a reason I'm not getting grub runs after kernel installs, after upgrading to edgy?03:00
cjb.. or initrds made.03:00
zuler....known bug03:00
cjbAh, thanks. 03:03

mjg59BenC: Keybuk: Someone's complaining that since the dapper kernel update, the kernel can't find their root filesystem03:48
mjg59Oh, scratch that, he's being confusing about timing03:50
msemtdmjg59: I'm confused!03:51
mjg59msemtd: Ah, you're in here too03:51
mjg59Excellent03:51
msemtdyup - looking for Keybuk!03:51
mjg59Right03:53
mjg59So was the machine running the released version of dapper previously?03:53
msemtdyes - it's been dapper for a few weeks03:54
msemtdI upgraded from breezy03:54
mjg59msemtd: Ok. There have been no udev updates during that time period.03:54
mjg59So it's certainly not a udev issue.03:54
msemtdthe upgrade went well03:55
msemtdI was assuming my rpoblem was simillar to some of the others' who report a simillar hang03:55
zulis it sata?03:56
msemtd...although I only have a single IDE HDD with / & swap03:56
mjg59msemtd: The "hang" is what happens when you don't have a device node for your root file system03:56
mjg59There are various reasons why that could happen03:56
mjg59It could be udev fucking up, or it could be the kernel fucking up03:57
mjg59In this case it sounds more like a kernel issue than a udev one03:57
msemtd...or both! :)03:57
msemtdyeah - it followed a kernel upgrade03:57
msemtdbut now the older kernels won't find root either03:57
msemtdI could keep trying different root=/dev/xxx from grub03:59
msemtdmjg59: should I boot with break=top ?04:01
mjg59msemtd: That would be a good start04:01
msemtdwhat to I need to do to load the device driver module following that?04:02
mjg59modprobe module_name04:02
msemtdI suppose that's IDE04:02
mjg59Depends on what sort of controller you have04:02
mjg59There's probably a specific module04:02
mjg59What sort of motherboard chipset?04:02
msemtdit's onboard ide SiS04:03
mjg59Ah, hang on04:03
mjg59Do break=premount04:03
mjg59Rather than break=top04:03
mjg59Then the module should be loaded04:03
mjg59Sorry, break=mount04:03
mjg59Then go into /dev and see what hd* nodes there are04:03
msemtdok, break=mount - look in /dev - goddit04:04
msemtdhmm, will I have a shell by then?04:04
msemtdBusyBox?04:04
msemtd...from initrd?04:04
Keybukmjg59, msemtd: hmm?04:12
mjg59msemtd: Yup04:12
msemtdKeybuk: sorry - I thought my boot problem was udev04:13
msemtdI have the root file system not found following linux-image-2.6.15-26-686 upgrade04:13
msemtd...hangs at "Waiting for root file system" then gives up on /dev/hda1 and gives me a BusyBox shell04:14
msemtdtried acpi=off noapic irqpoll etc (my usual workarounds :) )04:16
msemtdtried reinstalling older kernels but whilst chrooted from a knoppix 2.6 kernel so dunno if that'd screw things up04:18
msemtdwhy would older kernels (that previously worked) fail to boot when reinstalled? I sit because grub is pointing to a different udev device?04:34
msemtds/I sit/Is it/04:34
mjg59Grub's configuration won't have changed04:42
msemtdthe apt-get install will have run grub-update won't it?04:47
mjg59Yes. That doesn't change the grub configuration.04:52
mjg59Unless your config was already broken before you installed the kernel04:52
msemtdI think the grub config is fine - each new kernel I apt-getted whilst under knoppix got added04:53
mjg59But until you do the test, we're going to have no idea04:54
msemtdtrue - I'll be trying tonight04:54

mjg59Sorry06:30
mjg59grep 0x0101 /sys/bus/pci/devices/*/class06:30
mjg59And then go to the directory with a match and do06:30
mjg59cat vendor06:30
mjg59cat device06:30
msemtd_sorry, mjg59 I'll have to get back to this one - got to sort the kids out06:33
mjg59Ok06:33
KeybukBenC: we're not going with .18, right?06:34
msemtd_vendor is 0x1039 device is 0x551306:36
BenCKeybuk: no06:36
mjg59msemtd_: Hm. Odd. sis5513 should bind to that06:38
mjg59msemtd_: Can you do rmmod ide_generic; modprobe sis551306:38
KeybukBenC: GregKH has some more random sysfs changes happening, I assume those are for .18 or .19 and didn't go into .1706:38
BenCnothing scary in .17 that I'm aware of06:39
Keybukaye, /sys/class in .17 is still just class_dev06:39
msemtd_mjg59: hmm, says "neither ide port enabled"!06:39
mjg59msemtd_: Right. Interesting.06:41
msemtd_mjg59: ah it seems ide0 and ide1 are taken!06:41
mjg59msemtd_: Is ide_generic unloaded?06:41
msemtd_sorry - i'll get back to this later06:42
mjg59Ok06:42
KeybukBenC: any particular reason for the conservative kernel choice?  bad experience with dapper?06:42
mjg59Keybuk: We have no especially good idea when 2.6.18 will be released06:43
BenCKeybuk: not only that, but I didn't want to be chasing upstream kernel bugs+fixes for most of the release cycle06:56
BenCwhen we did dapper, .15 was opened right before dapper started, and I knew we'd have 3 months of settling after .15 was released06:58
BenC.18 was opened shortly after edgy started, and we'd probably only have 6 weeks max after .18 was released before edgy released06:59
Keybukseems fair07:23
jbaileyBenC: And that's assuming that any work gets done in August on 2.6.18, which I think unlikely.07:45
jbaileySummers are great for development when it's mostly students.  Crap when it folks with spouses, kids, and vacation time who hack for a living.07:45
BenCjbailey: Sorry, I missed most of what you said...was outside in the swimming pool with my kids, and then played some volleyball  ;)07:51
KeybukBenC: we're so not fooling for your "I have a life outside of work" pretence07:52
zulheh07:59
jbaileyBenC: *lol*08:02
BenChehe08:15
BenCno sign of Mith, but I'm sure he will allow an exception for a new kernel, given that the current kernel wont boot after install08:24

BenCfabbione: New pbbuttonsd handles keyboard backlighting on my pb now!09:12
fabbioneBenC: yes i saw it!09:19
BenCit's using a different hueristic than macosx does though09:21
BenCon osx, if you were in complete darkness, the keyboard lights were actually a bit dimmer than if you were in partial light09:21
BenCit got brighter, then dimmer as the light decreased09:21
fabbioneBenC: yes, there is a sensor on the keyboard that enable/disable backlight automatically in MacOS09:21
fabbioneyeah09:22
fabbioneMacOS was either on/off or manual09:22
fabbionethe new psbuttunds is more smooth09:22
BenCmacosx was smoother for me09:22
fabbionehmmm09:22
BenCit was automatic09:22
fabbionei will check again...09:22
fabbioneit's rare i work in the dark anyway09:22
BenCsame here, but it's nice when the light is as the threshold where the black-on-grey keys are hard to read09:23
