| login_ | hello | 12:58 |
|---|---|---|
| login_ | I have been compiling kernel 2.6.22 and have run across a dilemna. My compiled kernel weighs in at about 400-500 mb while the ubuntu kernel weighs about 100-200 mb. How did you guys get the kernel to be so thin?While i was uncompressing the kernel i saw it uncompress folders such as sparc so is it possible that my kernel installed all architectures? if so , how can i make it only use 1386? | 01:00 |

| mikmorg | Could someone assist me as to where the debian post/pre inst/rm scripts can be found for linux-image, linux-headers, and linux-source? I figured they would be somewhere in git://kernel.ubuntu.com/ubuntu/ubuntu-feisty.git, but I can't find them. | 05:24 |
| crimsun | that's because make-kpkg (in the kernel-package binary package) handles it. | 05:28 |
| mikmorg | crimsun: Do you know where I should send a patch to those files? | 05:29 |
| mikmorg | crimsun: There is a problem with the kernel-img.conf parsing that needs to get fixed ASAP, hopefully before 16-30 comes out | 05:29 |
| crimsun | mikmorg: file a bug against the kernel-package source package, and attach the diff(s). | 05:33 |
| mikmorg | crimsun: I filed the patches against the files in /var/lib/dpkg/info/linux-*. I will change the target from linux-source to kernel-package. Thanks. | 05:36 |

| aquo | BenC: can you tell me who is responsible for bug what is the status on https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/50214 | 03:13 |
| BenC | aquo: how about giving me a quick overview so I don't have to read the entire report, please? | 03:14 |
| aquo | kernel is compiled with wrong Wireless Extension | 03:14 |
| BenC | kernel is compiled with stock 2.6.22 wireless extensions | 03:15 |
| BenC | it's the only way it can be compiled | 03:15 |
| aquo | aquo@cayley:/etc$ iwconfig --version | 03:15 |
| aquo | iwconfig Wireless-Tools version 28 | 03:15 |
| aquo | Compatible with Wireless Extension v11 to v20. | 03:15 |
| aquo | Kernel Currently compiled with Wireless Extension v21. | 03:15 |
| aquo | ath0 Recommend Wireless Extension v13 or later, | 03:15 |
| aquo | Currently compiled with Wireless Extension v21. | 03:15 |
| BenC | I don't see the problem there | 03:15 |
| BenC | v20 wireless-tools works fine with v21 kernel extensions | 03:15 |
| aquo | no, not everytime. | 03:15 |
| BenC | then wireless-tools needs updating | 03:16 |
| aquo | it is not possible to connect to hidden networks | 03:16 |
| BenC | it's not like I can tell the kernel to be v20 | 03:16 |
| BenC | how can you be sure that v21 kernel extensions is what is causing that? | 03:16 |
| BenC | these extensions are meant to be compatible in cases like this | 03:16 |
| aquo | should be possible, the bug report states that people solved the problem by recompiling the kernel | 03:16 |
| BenC | v20 wireless-tools just wont use the v21 extensions | 03:17 |
| BenC | recompiling it how? | 03:17 |
| aquo | not sure, changing the version of Wireless Extension v21 | 03:17 |
| BenC | I heard about this whole thing last week, and I'm just not convinced that v21/v20 compatibility is the problem | 03:17 |
| BenC | aquo: if you just change a line in the kernel to say it's v20, then you are actually breaking things | 03:18 |
| rtg | I think its more a problem with hidden SSID, not WEXT versions. | 03:18 |
| rtg | There is alot of FUD in that report. | 03:19 |
| BenC | yeah, the version information is a red herring, IMO | 03:19 |
| aquo | i don't think so, i would be interesting to see if it worked with the original kernel on the media ... | 03:19 |
| aquo | 20-15 | 03:19 |
| BenC | aquo: you can't compare 2.6.20 vs. 2.6.22 just based on v20/v21 kernel extensions | 03:19 |
| rtg | Yeah, there is too much change in the wireless subsystem. | 03:20 |
| aquo | i am just comparing 20-15 and 20-16 | 03:20 |
| BenC | the bug could very well be somewhere else, or it could be in wireless-tools, and the fact that it breaks because it assuming something it shouldn't | 03:20 |
| aquo | i am still on feisty | 03:20 |
| rtg | aquo: Can you confirm it works if you enable broadcast SSID? | 03:20 |
| BenC | aquo: ok, then I'm getting ever more conflicting info on this bug report | 03:21 |
| aquo | yes, with broadcast it is working. | 03:21 |
| rtg | aquo: I think that implies the WEXT versions are fine. There might be something between wpa_supplicant and network manager. | 03:21 |
| aquo | hoe, i think it is a major problem if i am not able to connect to hidden networks | 03:22 |
| BenC | aquo: I read a little more of the report, and it seems that the wireless-tools maintainer is agreeing with your assumption that v20 tools is breaking with v21 extensions | 03:23 |
| BenC | aquo: IMO, that clearly says that wireless-tools for v20 extensions is broken | 03:24 |
| aquo | "Hi Julie, upgrading only wireless tools won't make difference, because the kernel is recompiled with Wireless Extension version that is not supported by Wireless Tools. This is a simple mismatch and the kernel team can easily solve this by recompiling the kernel. I already did that on my system and it works." | 03:24 |
| BenC | aquo: I'd really like someone to tell me how to recompile the kernel with an older wext | 03:25 |
| BenC | that bit of info seems to be clearly absent from the report | 03:25 |
| aquo | don't know, but i will investigate. | 03:25 |
| BenC | it's not like it's a switch, or a config options...it's basically backing down the entire tree, subsystem and drivers, to older code | 03:25 |
| BenC | which we wont do | 03:26 |
| aquo | but first i want to check the situation on the original release media ... | 03:26 |
| BenC | so if newer wext tools fixes things, best bet is to find the patch that fixes this case | 03:26 |
| aquo | want to check if normal feisty has matching versions | 03:26 |
| BenC | we wont be making sweeping "downgrade wext" or "upgrade wireless-tools" changes in feisty, period | 03:27 |
| BenC | aquo: I'd also appreciate if you could update this bug report with what we discussed, to keep everyone informed of the status | 03:29 |
| aquo | ok | 03:30 |
| BenC | aquo: thanks | 03:32 |

| movi | i think i found a bug in the newest kernel in gutsy (and -7 too) | 04:41 |
| movi | the thing is, im using a Celeron 2.6 | 04:41 |
| movi | and ksoftirqd/0 is using about 25-30% of the cpu all the time | 04:42 |
| movi | someone pointed me to look and /proc/interrupts | 04:42 |
| movi | and the thing is, timer only generates 62 interrupts, then stops | 04:42 |
| movi | i tried booting with noapic and lapic | 04:43 |
| movi | n | 04:43 |
| movi | noapic and nolapic | 04:43 |
| movi | and then the timer does generate interrupts, but the process eats up 35% of the cpu all the time | 04:43 |

| movi | 2.6.20 (on 7.04) works perfectly | 04:44 |
| kylem | while the timer "doesn't" generate interrupts, is "LOC" increasing? | 04:44 |
| movi | yes | 04:44 |
| movi | and lots it too | 04:44 |
| kylem | then it's fine. | 04:44 |
| kylem | LOC is the local APIC timer | 04:44 |
| movi | why the cpu usage then ? | 04:45 |

| login_ | Hi guys. I recompiled kernel 2.6.22 on my ubuntu box and comparing to ubuntu's kernel , it is ismply 5 times larger! my deb file is 194 mb and when i isntall it , it is 500 mb. From synaptic , i see that the ubuntu kernel is about 75 mb . how can i make my 2.6.22 compiled kernel thinner? | 04:45 |
| movi | i | 04:45 |
| movi | i booted in single mode too to rule-out any rigue processes - nothing | 04:45 |

| mjg59 | login_: The Ubuntu kernel build process strips the modules before putting them in a package. If you do it by hand (without using the full kernel build process) you need to do that yourself. | 09:03 |
| login_ | o so i run find /lib/modules/ -name \*.ko | xargs strip while compiling | 09:04 |
| mjg59 | No, when installed | 09:05 |
| mjg59 | And I suspect you don't want to run strip without any arguments - that'll remove symbols needed for loading the modules | 09:06 |
| mjg59 | But this really isn't the place to ask | 09:06 |
| mjg59 | If you want to avoid it altogether, just disable CONFIG_KALLSYMS_ALL | 09:06 |
| login_ | i disabled that but it only went down a couple of kb | 09:07 |
