[03:06] <mozmck> 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] <mozmck> anyone here?
[03:53] <dandel> mozmck, yes.
[03:55] <dandel> 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)

[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-<flavour> only creates .deb files, no .dsc and/or .changes
[07:58] <AceLan> _ruben: debuild -S -sa -i -I
[08:01] <_ruben> AceLan: i doubt that that'd make my binary .debs "dput-able" ?
[08:05] <AceLan> _ruben: yes, it will produce necessary files dput needs
[08:05] <AceLan> including .dsc and .changes
[08:13] <_ruben> the changes files only references the source, not the binaries i had already built
[10:50] <cankoy_> Does the swap part. have to be *at least* the same size as RAM for hibernation to work?
[10:51] <cankoy_> I vaguely remember that Ubuntu kernel does some compression, hence swap d
[10:51] <cankoy_> ...could be less
[10:53] <hyperair> depends.
[10:53] <hyperair> there are three approaches for hibernation.
[10:53] <hyperair> swsusp, uswsusp, and tuxonice
[10:54] <hyperair> ubuntu uses swsusp by default.
[10:54] <hyperair> uswsusp compresses the image, and so does tuxonice
[10:54] <hyperair> but imo tuxonice does it best
[10:54] <hyperair> swsusp is extremely slow, and uswsusp is slightly less slow, but that's a different matter.
[10:54] <hyperair> cankoy_: ^
[10:55] <cankoy_> hyperair: so the default scheme does not compress?
[10:55] <hyperair> it does not
[10:55] <cankoy_> hm, ok
[10:55] <hyperair> it also does not save/restore the file cache upon resuming
[10:56] <hyperair> 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] <hyperair> iow, for now, hibernation sucks and you're better off not using it >_>
[10:57] <cankoy_> ok, thanks for insight, much appreciated ;-)
[10:57] <hyperair> np
[13:39] <Kano> hi, how about .32-rc8?
[16:16] <JohnT> 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] <mozmck> you don't have isolcpus set in the boot line do you?  (disclaimer - I know almost nothing!)
[16:20] <JohnT> no, just googled isolcpus: didn't even know it :)
[16:30] <nick_schembri> hello, Can someone comment on aufs  in 10.4 lucid
[16:36] <nick_schembri> cj you work on the cdrom build?
[16:41] <mozmck> 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] <cj> nick_schembri: nope.  that was kinda' random...
[16:53] <cankoy> 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] <nick_schembri> 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] <mozmck> 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] <mozmck> my custom kernel boots now that is.
[17:00] <mozmck> so how do I make it use those modules in the initrd created when I build debs?  (I used make-kpkg)
[17:01] <cankoy> mozmck: IIRC, you cannot use vesafb on intel gpu because it conflicts with KMS (and inteldrmfb)
[17:01] <dandel> i tested bug 484943 on native ext3 suspend, and it crashed just like what it did with a wubi based install.

[17:02] <mozmck> cankoy: I had to use nomodeset on this one to get it to boot reliably and to find the correct resolution.
[17:04] <mozmck> 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] <mozmck> the Ubuntu kernel has an initrd directory under /lib/modules/2.6.31-15-generic with the vesafb mod copied in.
[17:27] <cj> nick_schembri: seen jigdo?
[17:28] <nick_schembri> cj: i sorry what?
[17:28] <nick_schembri> cj: googling
[17:31] <cj> nick_schembri: oh, you're not trying to build a cdrom, eh?
[17:31] <nick_schembri> cj: look cool. 
[17:32] <nick_schembri> no I run ubunt on a flash based system with aufs protecting the flash.
[17:32] <nick_schembri> https://help.ubuntu.com/community/aufsRootFileSystemOnUsbFlash
[17:32] <nick_schembri> I need to update my comments on the status of aufs in 10.4+ 
[17:32] <cj> nick_schembri: nice.  might be useful for pyramid...
[17:32] <cj> http://code.google.com/p/pyramidlinux/
[17:33] <cj> it's based on a really old ubuntu, though, IIRC
[17:34] <nick_schembri> cj: i'll look at the website.  
[17:34] <nick_schembri> 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] <nick_schembri> root aufs should be very simple to install and remove.
[17:35] <cj> nick_schembri: I dunno.  I've never used aufs
[17:36] <nick_schembri> It's worked very well for me. I've never had any issues.
[17:36] <cj> you'll probably need to make-kpkg your own kernel with your own .config, though, I guess
[17:37] <nick_schembri> at this point the aufs modules are installed. I just need to install the userland tools and run the updates for initrd. 
[17:40] <nick_schembri> 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] <nick_schembri> 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] <cj> yeah, it's getting pretty ancient ;)
[17:44] <cj> but it's small
[17:44] <cj> I'd like to see embdebian get some love
[17:45] <nick_schembri> 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] <cj> indeed.  sorry I don't know more ;)
[17:48] <nick_schembri> 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] <nick_schembri> cj: np 
[17:49] <cj> 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] <cj> M of flash
[17:50] <nick_schembri> cj you should look at voyage linux it's easy to strip down. At one point it was less then 50M. 
[17:52] <nick_schembri> 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] <nick_schembri> cj it looks like voyage is moving to tmpfs and it needs 128M of flash. :(
[18:33] <cj> yeah, mine's a Soekris 45xx
[18:33] <dandel> any good information on adding automatic scan entries to grub2 (like adding text mode)

[18:44] <cj> oh, grub2, not grub1
[18:44] <cj> nm
[18:44]  * cj isn't familiar with that beast yet
[18:46] <dandel> 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] <dandel> cj, you running ubuntu 9.10 with ext3 by any chance?
[18:53] <cj> I am
[18:53] <dandel> does your system crash when you suspend? (ext3 errors.)
[18:53] <cj> no
[18:53] <cj> suspend is working pretty well for me aside from sony hardware issues
[18:54] <dandel> strange, me and a buddy with 2 different laptops have an issue with suspend crashing.
[18:54] <cj> (unplugging ac sometimes kills power)
[18:54] <cj> dandel: did you upgrade or install karmic fresh?
[18:54]  * cj upgraded
[18:54] <dandel> both
[18:54] <dandel> upgrade on wubi, and fresh install to native partition both show the same problem
[18:54] <cj> hurm... did you send the kernel bug report?
[18:54] <dandel> yes
[18:54] <cj> anyone respond to it yet?
[18:55] <cj> or mark it as a dup of something else?

[18:55] <cj> wubi?
[18:55] <dandel> i need to update it a bit tho.
[18:55] <dandel> wubi = windows installer for ubuntu
[18:55] <cj> ah
[18:55] <cj> yeah, that's not me...
[18:57] <dandel> my fresh install is to an actual hd partition (extended partition tho)
[18:57] <cj> lvm++
[18:57] <cj> is your friend's to an extended partition?
[18:57] <cj> if so, it might have something to do with extended + ext3.  that's something I've never used before.
[18:58] <dandel> no, wubi based.
[18:58] <cj> maybe grub doesn't know how to access sda[5..n] ?
[18:58] <dandel> no.
[18:58] <cj> dandel: is wubi an ext3 image on a ntfs partition or something?
[18:58] <dandel> on ntfs.
[18:58] <dandel> the laptop boots in just fine.
[18:59] <dandel> but once i do a suspend, it fails horribly.
[18:59] <dandel> see log on the bug
[19:22] <dandel> 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 ><;
