=== calc_ is now known as calc [06:45] moin === asac_ is now known as asac [12:36] 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 ? [12:36] Launchpad bug 220640 in linux "[hardy] iwl3945 + wpasupplicant fails to connect to university network. regression from gutsy (ipw3945+wpasupplicant)" [Undecided,New] === cradek_ is now known as cradek [12:49] ubuntudemon: https://bugs.edge.launchpad.net/ubuntu/+bug/219268 [12:49] Launchpad bug 219268 in ubuntu "iwl3945 doesn't work with my wifi card (ipw3945 did)" [Undecided,New] [13:39] ubuntudemon: we don't have ipw3945 in hardy [13:50] ubuntudemon: oops, misread the bug title [13:51] ubuntudemon: anyway, install linux-backports-modules-hardy-generic [13:51] reboot and try that [13:57] ubuntudemon: did you see http://ubuntuforums.org/showthread.php?p=4612681 ? [14:01] 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] ubuntudemon: the main point on that page was the "options iwl3945 disable_hw_scan=1" [14:03] the led is just a minor nag [14:03] alex_joni does that work from a live cd ? [14:05] ubuntudemon: it might [14:13] 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 [14:13] Launchpad bug 220640 in linux "[hardy] iwl3945 + wpasupplicant fails to connect to university network. regression from gutsy (ipw3945+wpasupplicant)" [Undecided,New] [14:18] alex_joni : I'm also talking in #ubuntu-bugs about this problem [14:22] ubuntudemon: on a livecd boot do: sudo modprobe -r iwl3945; modprobe iwl3945 disable_hw_scan=1 [14:29] 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] BenC: it might be that starting the module once confuses the HW, and it won't work until a next reboot [14:35] ubuntudemon: try disabling the module when starting the LiveCD.. I think there is a bootoption to disable a certain module from loading [14:37] 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] Launchpad bug 220640 in linux "[hardy] iwl3945 + wpasupplicant fails to connect to university network. regression from gutsy (ipw3945+wpasupplicant)" [Unknown,Confirmed] [14:39] Is there a way to give disable_hw_scan=1 at bootup (using the live cd) ? [14:40] ubuntudemon: Press F6. [14:40] module_name.parameter_name=value [14:41] so it's : iwl3945.disable_hw_scan=1 [14:41] so I would try iwl3945.disable_hw_scan=1 in the boot param list (the one you get with F6) [14:41] I'm trying now [14:42] I added it at the end of the line [14:42] unknow boot option .... ignoring [14:42] I must have done something wrong .. trying again [14:43] again the "unkown boot option" thing [14:45] I just tried again with the same result.. so I must be doing something wrong [14:47] I'm pressing F6 and typing iwl3945.disable_hw_scan=1 at the end of the line. [15:04] What about including the ipw3945 module in Ubuntu as an option ? It's possible see : http://james.colannino.org/downloads.html [15:08] ubuntudemon: Hardy is being released tomorrow :) And ipw3945 isn't supported by Intel anymore. [15:12] 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] ioctl[SIOCSIWSCAN] Device or resource busy [15:13] amitk : I know but I also found that a lot of people have all kinds of issues with iwl3945 [15:16] ubuntudemon: have you tried LBM? It has a more recent release of iwlwifi. [15:19] rtg_ no I haven't. I have never heard about LBM. [15:20] Do you mean linux-backports-modules ? Yes I have tried it. [15:20] ubuntudemon: try installing linux-backports-modules for Hardy. [15:20] ubuntudemon: oh. [15:32] ubuntudemon: did you reboot after doing so? [15:34] 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] 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] sudo modinfo iwl3945 | grep srcversion gives : srcversion: FDE2E62843DE3ED112A50C3 [15:46] Is there anything else I can try from the live cd ? [15:50] 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] 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] Bye all! [16:33] hello [16:33] 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] it starts using the hard disk in about every 20 minutes for 1-3 minutes [16:33] and it slows down my system even slows applications like firefox inspite of the fact that CPU usage shows 30% only [16:34] why kjournald takes so much time? (if it is the culprit) [16:44] i made a `ps faux`: http://pastebin.com/d34cda402 === calc_ is now known as calc [18:51] anybody? [19:55] boritek: are you sure it isn't the trackerd? [19:56] BenC, well it doesnt come up in the iotop or atop list [19:56] and i turned the updating off [19:56] is it swapping? [19:57] i dont think so, it keeps having 5% only [20:02] BenC, http://pastebin.com/d34cda402 [20:06] No, I mean is your system using swap [20:41] BenC: guess -16 will be the one for tomorrow? [20:41] yeah [20:42] cool :) [20:55] 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: (the driver works fine on Gutsy) [21:06] fbond: I'm confused. how do you build LBM 2.6.22 on Feisty? That is a Gutsy package. [21:11] rtg: I modified it slightly and turned it into a 2.6.20 package. [21:11] rtg: It only contains updated ALSA modules. [21:12] 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] 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] fbond: yeah, I think you're on own on this one. I would suspect incorrect headers or something. [21:13] s/on own/on your own/ [21:21] rtg: thanks [21:33] BenC, yes i have 2GB swap [21:33] boritek: but is it being used is what I am asking [21:33] boritek: like have you exhausted your memory and progs are swapping out [21:34] BenC, my Gnome-panel says the system is using 5% swap [21:35] i have 1GB RAM 61%used, 33%cache [21:35] boritek: can you pastebin /proc/meminfo [21:36] BenC, http://pastebin.com/d6c5bea6d [21:38] boritek: I suspect you are just getting swap usage and that causes disk usage [21:38] BenC, i never experienced this earlier [21:39] and it does it when i even dont do anything particular [21:39] you may have more things running, or they may be using more memory [21:39] if there is 33% cache it can just free it up, right? [21:40] so there is plenty of memory, and swap isnt really used, its only 5% [21:40] it's still ~90Megs used, so there is something being written to it [21:41] and reserving disk for 2-3minutes it could read and write more hundred MBs [21:43] i shot down may services like, postfix, mysql, postgresql, and it still does this [21:43] many* [21:46] BenC, i also got 100 iowait which is definitly abnormal i think [21:46] 100% [21:47] system is quite unresponsive at those times [21:55] BenC, swap is not being in use [21:56] i am just watching it with iotop [22:17] how have the ubuntu kernel diverged from the standard linux kernel? [22:17] and are the changes drastic? [22:19] http://kernel.ubuntu.com/git/ [22:21] so what is the best way to dive into kernel development? [22:21] Linux? BSD? something distro-specific? [22:21] Linux [22:21] http://kernelnewbies.org, probably [22:22] I am wondering if I should first implement my own kernel [22:22] to get hands on experience on how everything ties together [22:26] only if you have 2-3 years ;) [22:28] writing/fixing drivers might be a start though [22:28] sounds good :) [22:29] AFAIK kernelnewbies is a good resource to get started [22:29] thanks
