[12:36] <ubuntudemon> Hey. Can I do anything to provide more information to this bug ? https://bugs.launchpad.net/ubuntu/+source/linux/+bug/220640 And does anybody know how to use ipw3945 with Hardy's kernel ?

[13:39] <BenC> ubuntudemon: we don't have ipw3945 in hardy
[13:50] <BenC> ubuntudemon: oops, misread the bug title
[13:51] <BenC> ubuntudemon: anyway, install linux-backports-modules-hardy-generic
[13:51] <BenC> reboot and try that
[13:57] <alex_joni> ubuntudemon: did you see http://ubuntuforums.org/showthread.php?p=4612681 ?
[14:01] <ubuntudemon> alex_joni thanks. but I don't think that will work. I don't have any LED issues. I'll try just in case :)
[14:03] <alex_joni> ubuntudemon: the main point on that page was the "options iwl3945 disable_hw_scan=1"
[14:03] <alex_joni> the led is just a minor nag
[14:03] <ubuntudemon> alex_joni does that work from a live cd ?
[14:05] <alex_joni> ubuntudemon: it might
[14:13] <ubuntudemon> alex_joni thanks for the suggestion. it didn't work but I got different errors see : https://bugs.launchpad.net/linux/+bug/220640/comments/9

[14:18] <ubuntudemon> alex_joni : I'm also talking in #ubuntu-bugs about this problem
[14:22] <BenC> ubuntudemon: on a livecd boot do: sudo modprobe -r iwl3945; modprobe iwl3945 disable_hw_scan=1
[14:29] <ubuntudemon> BenC : Thanks for the suggestion. I've tried something like that. It gives different error messages like "ioctl[SIOCSIWSCAN] Device or resource busy". I'm trying again to put more debugging information on this in the bug report.
[14:35] <alex_joni> BenC: it might be that starting the module once confuses the HW, and it won't work until a next reboot
[14:35] <alex_joni> ubuntudemon: try disabling the module when starting the LiveCD.. I think there is a bootoption to disable a certain module from loading
[14:37] <ubuntudemon> BenC : Here's the newest debugging log : https://bugs.launchpad.net/linux/+bug/220640/comments/11  (different errors than when not using disable_hw_scan)
[14:37] <ubotu> Launchpad bug 220640 in linux "[hardy] iwl3945 + wpasupplicant fails to connect to university network. regression from gutsy (ipw3945+wpasupplicant)" [Unknown,Confirmed] 
[14:39] <ubuntudemon> Is there a way to give disable_hw_scan=1 at bootup (using the live cd) ?
[14:40] <soren> ubuntudemon: Press F6.
[14:40] <alex_joni> module_name.parameter_name=value
[14:41] <ubuntudemon> so it's : iwl3945.disable_hw_scan=1
[14:41] <alex_joni> so I would try iwl3945.disable_hw_scan=1 in the boot param list (the one you get with F6)
[14:41] <ubuntudemon> I'm trying now
[14:42] <ubuntudemon> I added it at the end of the line
[14:42] <ubuntudemon> unknow boot option .... ignoring
[14:42] <ubuntudemon> I must have done something wrong .. trying again
[14:43] <ubuntudemon> again the "unkown boot option" thing
[14:45] <ubuntudemon> I just tried again with the same result.. so I must be doing something wrong
[14:47] <ubuntudemon> I'm pressing F6 and typing iwl3945.disable_hw_scan=1 at the end of the line. 
[15:04] <ubuntudemon> What about including the ipw3945 module in Ubuntu as an option ? It's possible see : http://james.colannino.org/downloads.html
[15:08] <amitk> ubuntudemon: Hardy is being released tomorrow :) And ipw3945 isn't supported by Intel anymore.
[15:12] <ubuntudemon> After a reboot and using "sudo modprobe -r iwl3945 ; sudo modprobe iwl3945 disable_hw_scan=1" I'm seeing both errors in one run : ioctl[SIOCSIWENCODEEXT]: Invalid argument 
[15:12] <ubuntudemon> ioctl[SIOCSIWSCAN] Device or resource busy
[15:13] <ubuntudemon> amitk : I know but I also found that a lot of people have all kinds of issues with iwl3945
[15:16] <rtg_> ubuntudemon: have you tried LBM? It has a more recent release of iwlwifi.
[15:19] <ubuntudemon> rtg_ no I haven't. I have never heard about LBM. 
[15:20] <ubuntudemon> Do you mean linux-backports-modules ? Yes I have tried it.
[15:20] <rtg_> ubuntudemon: try installing linux-backports-modules for Hardy.
[15:20] <rtg_> ubuntudemon: oh.
[15:32] <BenC> ubuntudemon: did you reboot after doing so?
[15:34] <ubuntudemon> BenC : I'm running of a Hardy livecd (RC). I'm running an encrypted Gutsy installation on my harddrive and I don't want to upgrade if I can't get wireless to work.
[15:35] <ubuntudemon> But installing linux-backports-modules and modprobing iwl3945 seemed not to need a reboot because i'm seeing the led_class module which I didn't see before
[15:39] <ubuntudemon> sudo modinfo iwl3945 | grep srcversion gives : srcversion: FDE2E62843DE3ED112A50C3
[15:46] <ubuntudemon> Is there anything else I can try from the live cd ?
[15:50] <ubuntudemon> Tomorrow I'm helping someone who runs Gutsy to get on this wireless network. He also has intel 3945 wireless. Maybe we'll have time to test hardy live on his machine.
[15:51] <ubuntudemon> If there is nothing else I can try I'm going home and I'll try any new suggestions tomorrow. Thanks everybody for your help.
[16:07] <ubuntudemon> Bye all! 
[16:33] <boritek> hello
[16:33] <boritek>  My ubuntu hardy heron uses the hard disk too much and for too long. It seems that it is probably kjournald, pdflush, and/or syslogd
[16:33] <boritek> it starts using the hard disk in about every 20 minutes for 1-3 minutes
[16:33] <boritek> and it slows down my system even slows applications like firefox inspite of the fact that CPU usage shows 30% only
[16:34] <boritek> why kjournald takes so much time? (if it is the culprit)
[16:44] <boritek> i made a `ps faux`: http://pastebin.com/d34cda402
[18:51] <boritek> anybody?
[19:55] <BenC> boritek: are you sure it isn't the trackerd?
[19:56] <boritek> BenC, well it doesnt come up in the iotop or atop list
[19:56] <boritek> and i turned the updating off
[19:56] <BenC> is it swapping?
[19:57] <boritek> i dont think so, it keeps having 5% only
[20:02] <boritek> BenC, http://pastebin.com/d34cda402
[20:06] <BenC> No, I mean is your system using swap
[20:41] <alex_joni> BenC: guess -16 will be the one for tomorrow?
[20:41] <BenC> yeah
[20:42] <alex_joni> cool :)
[20:55] <fbond> Hi, sorry to bother with this sort of question: supposing I rebuilt ubuntu-backports-modules-2.6.22-14-generic on Feisty.  Everything seems to be in order, but the driver doesn't work correctly (snd-hda-intel).  I'm at a loss as to why that would be.  I get a DMA memory allocation error in dmesg.
[20:55] <fbond> fbond: (the driver works fine on Gutsy)
[21:06] <rtg> fbond: I'm confused. how do you build LBM 2.6.22 on Feisty? That is a Gutsy package.
[21:11] <fbond> rtg: I modified it slightly and turned it into a 2.6.20 package.
[21:11] <fbond> rtg: It only contains updated ALSA modules.
[21:12] <fbond> Those should work fine with either kernel version.  The snd-hda-intel driver in Feisty doesn't work with this hardware, but the snd-hda-intel from Gutsy does.  I can't dist upgrade the platform yet, though.
[21:12] <fbond> Seems that there's more to a working snd-hda-intel than what's in the module itself, though, and that caught me a bit by surprise.
[21:13] <rtg> fbond: yeah, I think you're on own on this one. I would suspect incorrect headers or something.
[21:13] <rtg> s/on own/on your own/
[21:21] <fbond> rtg: thanks
[21:33] <boritek> BenC, yes i have 2GB swap
[21:33] <BenC> boritek: but is it being used is what I am asking
[21:33] <BenC> boritek: like have you exhausted your memory and progs are swapping out
[21:34] <boritek> BenC, my Gnome-panel says the system is using 5% swap
[21:35] <boritek> i have 1GB RAM 61%used, 33%cache
[21:35] <BenC> boritek: can you pastebin /proc/meminfo
[21:36] <boritek> BenC, http://pastebin.com/d6c5bea6d
[21:38] <BenC> boritek: I suspect you are just getting swap usage and that causes disk usage
[21:38] <boritek> BenC, i never experienced this earlier
[21:39] <boritek> and it does it when i even dont do anything particular
[21:39] <BenC> you may have more things running, or they may be using more memory
[21:39] <boritek> if there is 33% cache it can just free it up, right?
[21:40] <boritek> so there is plenty of memory, and swap isnt really used, its only 5%
[21:40] <BenC> it's still ~90Megs used, so there is something being written to it
[21:41] <boritek> and reserving disk for 2-3minutes it could read and write more hundred MBs
[21:43] <boritek> i shot down may services like, postfix, mysql, postgresql, and it still does this
[21:43] <boritek> many*
[21:46] <boritek> BenC, i also got 100 iowait which is definitly abnormal i think
[21:46] <boritek> 100%
[21:47] <boritek> system is quite unresponsive at those times
[21:55] <boritek> BenC, swap is not being in use
[21:56] <boritek> i am just watching it with iotop
[22:17] <sleepster> how have the ubuntu kernel diverged from the standard linux kernel?
[22:17] <sleepster> and are the changes drastic?
[22:19] <crimsun> http://kernel.ubuntu.com/git/
[22:21] <sleepster> so what is the best way to dive into kernel development?
[22:21] <crimsun> Linux? BSD? something distro-specific?
[22:21] <sleepster> Linux
[22:21] <crimsun> http://kernelnewbies.org, probably
[22:22] <sleepster> I am wondering if I should first implement my own kernel
[22:22] <sleepster> to get hands on experience on how everything ties together
[22:26] <JanC> only if you have 2-3 years  ;)
[22:28] <JanC> writing/fixing drivers might be a start though
[22:28] <sleepster> sounds good :)
[22:29] <JanC> AFAIK kernelnewbies is a good resource to get started
[22:29] <sleepster> thanks
