[03:06] I made a custom kernel based on the ubuntu sources. In my /lib/modules/2.6.31-15-generic/ there is an initrd directory with vesafb.ko in it, but in my custom kernel's modules directory there is no initrd directory. Why is this? What do I need to do to get that? I built my package with make-kpkg. [03:35] anyone here? [03:53] mozmck, yes. [03:55] I'm doing a little bit of extra testing to see if bug 484943 is only valid on a wubi based install. (currently installing on a native hd partition) [03:55] Malone bug 484943 in linux "resume crashes with ext3 error with wubi based install" [Undecided,New] https://launchpad.net/bugs/484943 [07:57] <_ruben> could anyone enlighten me on how to add a custom built kernel (ubuntu git method) to our custom package mirror (which uses mini-dinstall)? [07:57] <_ruben> the debian/rules binary- only creates .deb files, no .dsc and/or .changes [07:58] _ruben: debuild -S -sa -i -I [08:01] <_ruben> AceLan: i doubt that that'd make my binary .debs "dput-able" ? [08:05] _ruben: yes, it will produce necessary files dput needs [08:05] including .dsc and .changes [08:13] <_ruben> the changes files only references the source, not the binaries i had already built [10:50] Does the swap part. have to be *at least* the same size as RAM for hibernation to work? [10:51] I vaguely remember that Ubuntu kernel does some compression, hence swap d [10:51] ...could be less [10:53] depends. [10:53] there are three approaches for hibernation. [10:53] swsusp, uswsusp, and tuxonice [10:54] ubuntu uses swsusp by default. [10:54] uswsusp compresses the image, and so does tuxonice [10:54] but imo tuxonice does it best [10:54] swsusp is extremely slow, and uswsusp is slightly less slow, but that's a different matter. [10:54] cankoy_: ^ [10:55] hyperair: so the default scheme does not compress? [10:55] it does not [10:55] hm, ok [10:55] it also does not save/restore the file cache upon resuming [10:56] and also only restores half of the memory after resuming, resulting in a whole load of page faults upon resuming. so even if your resume didn't take that long, it'll hang and page fault for another 3-4 minutes before you can use it again [10:56] iow, for now, hibernation sucks and you're better off not using it >_> [10:57] ok, thanks for insight, much appreciated ;-) [10:57] np === cankoy_ is now known as cankoy [13:39] hi, how about .32-rc8? === BenC1 is now known as BenC [16:16] Hi! My problem: I have an app with 4 threads wich should run at 100% on each core. I have a 4 core processor. The behavior is not obvious: 2 threads runs on their own core at 100%, while the other 2 shares one single core, leaving the other core idle. Why? [16:18] you don't have isolcpus set in the boot line do you? (disclaimer - I know almost nothing!) [16:20] no, just googled isolcpus: didn't even know it :) [16:30] hello, Can someone comment on aufs in 10.4 lucid [16:36] cj you work on the cdrom build? [16:41] how do I get my custom kernel's initrd to load the vesafb module by default? the kernel is built with the ubuntu sources and config from 2.6.31-15-generic. I found something on adding it to /etc/initramfs-tools/modules/ but will that work for installing the debs on another computer? [16:44] nick_schembri: nope. that was kinda' random... [16:53] mozmck: kernel .deb includes the initrd. But I'm not sure just adding vesafb to initramfs-tools/modules is enough to make it work. [16:53] cj yes that is a little random. I had your nic in my head. I know that the person who is working on the cdrom build will know if aufs is going to be removed from lucid 10.4. [16:58] cankoy: I installed on a computer with intel onboard gpu and it wouldn't boot. So I booted with ubuntu kernel and added vesafb and fbcon to initramfs-tools/modules, ran update-initramfs -c -k and now it boots fine. [16:59] my custom kernel boots now that is. [17:00] so how do I make it use those modules in the initrd created when I build debs? (I used make-kpkg) [17:01] mozmck: IIRC, you cannot use vesafb on intel gpu because it conflicts with KMS (and inteldrmfb) [17:01] i tested bug 484943 on native ext3 suspend, and it crashed just like what it did with a wubi based install. [17:01] Malone bug 484943 in linux "resume crashes with ext3 error with wubi based install" [Undecided,New] https://launchpad.net/bugs/484943 [17:02] cankoy: I had to use nomodeset on this one to get it to boot reliably and to find the correct resolution. [17:04] in x that is. with the standard kernel it worked but mine had to have the vesafb module - I guess to fall back on. [17:05] the Ubuntu kernel has an initrd directory under /lib/modules/2.6.31-15-generic with the vesafb mod copied in. [17:27] nick_schembri: seen jigdo? [17:28] cj: i sorry what? [17:28] cj: googling [17:31] nick_schembri: oh, you're not trying to build a cdrom, eh? [17:31] cj: look cool. [17:32] no I run ubunt on a flash based system with aufs protecting the flash. [17:32] https://help.ubuntu.com/community/aufsRootFileSystemOnUsbFlash [17:32] I need to update my comments on the status of aufs in 10.4+ [17:32] nick_schembri: nice. might be useful for pyramid... [17:32] http://code.google.com/p/pyramidlinux/ [17:33] it's based on a really old ubuntu, though, IIRC [17:34] cj: i'll look at the website. [17:34] cj: what i need to do is find out how long aufs will be in the kernel and build a package or ppa for the avg user. [17:35] root aufs should be very simple to install and remove. [17:35] nick_schembri: I dunno. I've never used aufs [17:36] It's worked very well for me. I've never had any issues. [17:36] you'll probably need to make-kpkg your own kernel with your own .config, though, I guess [17:37] at this point the aufs modules are installed. I just need to install the userland tools and run the updates for initrd. [17:40] I was hoping that linus would include aufs in the mainline kernel, but he hates the code for some reason. I'm not sure I want to maintane the patches if ubuntu pulls aufs out. [17:43] cj: pyramidlinux looks a little old. I started with voyage linux out of voyage.hk. It's a debian based system that I pulled some of the code from. [17:44] yeah, it's getting pretty ancient ;) [17:44] but it's small [17:44] I'd like to see embdebian get some love [17:45] cj thanks for talking with me. I need pgraner to get back with the official answer to aufs's status in 10.4 [17:48] indeed. sorry I don't know more ;) [17:48] cj: embdebian would be great. I've looked a little at using debootstrap to build a sub 50M distro on ubuntu. I just have not had the time and flash memory is so cheep now I'm not sure it's worth the time. I can live with a little bloat. [17:49] cj: np [17:49] nick_schembri: my problem is that I've already invested in the radio hardware I intend to use, and it's only got 64 [17:49] M of flash [17:50] cj you should look at voyage linux it's easy to strip down. At one point it was less then 50M. [17:52] Voyage Linux is Debian derived distribution that is best run on a x86 embedded platforms such as PC Engines ALIX/WRAP and Soekris 45xx/48xx board [17:54] cj it looks like voyage is moving to tmpfs and it needs 128M of flash. :( === BenC2 is now known as BenC [18:33] yeah, mine's a Soekris 45xx [18:33] any good information on adding automatic scan entries to grub2 (like adding text mode) [18:43] dandel: sure, :) [18:44] oh, grub2, not grub1 [18:44] nm [18:44] * cj isn't familiar with that beast yet [18:46] hmm... i found a little bit, but i really just don't want the updates to grub to knock out what i do ><; [18:47] cj, you running ubuntu 9.10 with ext3 by any chance? [18:53] I am [18:53] does your system crash when you suspend? (ext3 errors.) [18:53] no [18:53] suspend is working pretty well for me aside from sony hardware issues [18:54] strange, me and a buddy with 2 different laptops have an issue with suspend crashing. [18:54] (unplugging ac sometimes kills power) [18:54] dandel: did you upgrade or install karmic fresh? [18:54] * cj upgraded [18:54] both [18:54] upgrade on wubi, and fresh install to native partition both show the same problem [18:54] hurm... did you send the kernel bug report? [18:54] yes [18:54] anyone respond to it yet? [18:55] or mark it as a dup of something else?

[18:57] my fresh install is to an actual hd partition (extended partition tho) [18:57] lvm++ [18:57] is your friend's to an extended partition? [18:57] if so, it might have something to do with extended + ext3. that's something I've never used before. [18:58] no, wubi based. [18:58] maybe grub doesn't know how to access sda[5..n] ? [18:58] no. [18:58] dandel: is wubi an ext3 image on a ntfs partition or something? [18:58] on ntfs. [18:58] the laptop boots in just fine. [18:59] but once i do a suspend, it fails horribly. [18:59] see log on the bug === hggdh_ is now known as hggdh [19:22] cj, i figured out part of what i need, but it doesn't exactly transfer nicely to when i add dev kernels on boot params ><; [21:29] cking: how the hell do you update the BIOS of a Dell Mini 10v? [21:30] Keybuk, dunno - not done it on that machine.
