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

mikmorgCould 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
crimsunthat's because make-kpkg (in the kernel-package binary package) handles it.05:28
mikmorgcrimsun: Do you know where I should send a patch to those files?05:29
mikmorgcrimsun: There is a problem with the kernel-img.conf parsing that needs to get fixed ASAP, hopefully before 16-30 comes out05:29

mikmorgcrimsun: 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

aquokernel is compiled with wrong Wireless Extension03:14

aquo          Currently compiled with Wireless Extension v21.03:15
BenCI don't see the problem there03:15
BenCv20 wireless-tools works fine with v21 kernel extensions03:15
aquono, not everytime.03:15
BenCthen wireless-tools needs updating03:16
aquoit is not possible to connect to hidden networks03:16
BenCit's not like I can tell the kernel to be v2003:16
BenChow can you be sure that v21 kernel extensions is what is causing that?03:16
BenCthese extensions are meant to be compatible in cases like this03:16
aquoshould be possible, the bug report states that people solved the problem by recompiling the kernel03:16
BenCv20 wireless-tools just wont use the v21 extensions03:17
BenCrecompiling it how?03:17
aquonot sure, changing the version of Wireless Extension v2103:17
BenCI heard about this whole thing last week, and I'm just not convinced that v21/v20 compatibility is the problem03:17
BenCaquo: if you just change a line in the kernel to say it's v20, then you are actually breaking things03:18
rtgI think its more a problem with hidden SSID, not  WEXT versions.03:18
rtgThere is alot of FUD in that report.03:19
BenCyeah, the version information is a red herring, IMO03:19
aquoi don't think so, i would be interesting to see if it worked with the original kernel on the media ...03:19
BenCaquo: you can't compare 2.6.20 vs. 2.6.22 just based on v20/v21 kernel extensions03:19
rtgYeah, there is too much change in the wireless subsystem.03:20
aquoi am just comparing 20-15 and 20-1603:20
BenCthe 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't03:20
aquoi am still on feisty03:20
rtgaquo: Can you confirm it works if you enable broadcast SSID?03:20
BenCaquo: ok, then I'm getting ever more conflicting info on this bug report03:21
aquoyes, with broadcast it is working.03:21
rtgaquo: I think that implies the WEXT versions are fine. There might be something between wpa_supplicant and network manager. 03:21
aquohoe, i think it is a major problem if i am not able to connect to hidden networks03:22
BenCaquo: 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 extensions03:23
BenCaquo: IMO, that clearly says that wireless-tools for v20 extensions is broken03:24
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
BenCaquo: I'd really like someone to tell me how to recompile the kernel with an older wext03:25
BenCthat bit of info seems to be clearly absent from the report03:25
aquodon't know, but i will investigate.03:25
BenCit's not like it's a switch, or a config options...it's basically backing down the entire tree, subsystem and drivers, to older code03:25
BenCwhich we wont do03:26
aquobut first i want to check the situation on the original release media ...03:26
BenCso if newer wext tools fixes things, best bet is to find the patch that fixes this case03:26
aquowant to check if normal feisty has matching versions03:26
BenCwe wont be making sweeping "downgrade wext" or "upgrade wireless-tools" changes in feisty, period03:27
BenCaquo: I'd also appreciate if you could update this bug report with what we discussed, to keep everyone informed of the status03:29
BenCaquo: thanks03:32

movithe thing is, im using a Celeron 2.604:41
moviand ksoftirqd/0 is using about 25-30% of the cpu all the time04:42
movisomeone pointed me to look and /proc/interrupts04:42
moviand the thing is, timer only generates 62 interrupts, then stops04:42
movii tried booting with noapic and lapic04:43

login_plz anwser this will be my last question :'(08:56
bdmurraylogin_: you might find 'man strip' and 'man xargs' helpful08:59
login_i still dont get it .:(. O well. Does the gutsy kernel have any stamps on it saying it is an ubuntu kernel?09:02
mjg59login_: 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 compiling09:04
mjg59No, when installed09:05
mjg59And I suspect you don't want to run strip without any arguments - that'll remove symbols needed for loading the modules09:06
mjg59But this really isn't the place to ask09:06
mjg59If you want to avoid it altogether, just disable CONFIG_KALLSYMS_ALL09:06
login_i disabled that but it only went down a couple of kb09:07
