| kees | jjohansen, arjan: I will now get out of this communication loop. ;) | 00:38 |
|---|---|---|
| arjan | hehe thanks | 00:39 |
| jjohansen | arjan: I have kicked off a debug kernel build for you, I'll ping you when its done | 00:39 |
| arjan | all I need is the drivers/acpi/processor-idle.o file | 00:39 |
| === omani2 is now known as omani | ||
| arjan | http://www.kerneloops.org/oneweek31.php | 00:40 |
| arjan | that is currently mostly ubuntu reports (until Fedora 12 ships I suspect.. then it'll be amix) | 00:40 |
| arjan | looking at the nr 2 issue | 00:40 |
| arjan | and failing to make sense out of it without knowing exactly which instruction we're executing | 00:41 |
| arjan | -> hence the request for vmlinux or drivers/acpi/processor-idle.o | 00:41 |
| jjohansen | arjan: okay, I just build that then, it will be quicker | 00:45 |
| jjohansen | arjan: http://kernel.ubuntu.com/~jj/processor_idle.o | 00:57 |
| * arjan grabs | 00:58 | |
| arjan | thanks a lot! | 00:58 |
| arjan | ooh fun | 00:59 |
| arjan | this is in a paravirt hook | 00:59 |
| arjan | anyway that's good food-for-thought | 01:00 |
| arjan | thanks again | 01:00 |
| * arjan will ponder more after dinner ;) | 01:00 | |
| eswenson | Is there an irc channel where I can ask a question about the ubuntu/debian kernel build environment? | 01:19 |
| rtg | eswenson, this is the right channel, but most folks are about gone. can you post an email to the canonical-kernel-team@lists.canonical.com list? | 01:42 |
| eswenson | rtg: I could, but I'm not on the kernel team. I'm just a developer who has a need to update/add modules to a local copy of the kernel. Can I still send email to canonical-kernel-team list? | 01:44 |
| rtg | eswenson, yep, I'll moderate it later tonight. | 01:44 |
| eswenson | rtg: And my question regards the jaunty kernel, not the karmic kernel. Ok, I'll post the question to the list. THanks. | 01:45 |
| === bjf is now known as bjf-afk | ||
| indus_ | hello | 06:42 |
| Appiah | On launchpad bugs , should the team be the ones selecting confirmed and priotrity? | 09:19 |
| Appiah | or the team? | 09:19 |
| Appiah | or the user* i mean | 09:19 |
| JanC | Appiah: confirmed is if other people can reproduce the same bug, so it can be another user | 10:57 |
| JanC | priority is for the developers (or team managers or such) | 10:57 |
| JanC | never confirm your own bugs though ;) | 10:58 |
| apw | Appiah, yeah what JanC said ... the priority is covered by our 'policy' so data loss is critical, crashes are high or medium etc | 11:07 |
| apw | the status implies things about the bug, co | 11:07 |
| apw | confirmed for more than one user, trigaged for 'having all the data we need' etc | 11:08 |
| hyperair | does anyone know if there's a difference between the sreadahead and the ureadahead kernel patches? | 11:09 |
| hyperair | and how come the said patches aren't entering mainline? | 11:10 |
| apw | hyperair, yes the patches differ. and as it says in the leader to those patches, we are expecting a more sane common and standard way to trace all syscalls via ftrace which would superceed most of the patch | 11:20 |
| hyperair | @_@ | 11:21 |
| hyperair | i see | 11:21 |
| hyperair | you really meant header and not leader, right? | 11:22 |
| apw | those words mean the same thing to me for patches ... :) ... the description of the patch | 11:22 |
| hyperair | are you sure "leader" can be used in this context? | 11:23 |
| hyperair | "leader" applies to a person who leads, right? | 11:23 |
| apw | It's not upstream because it will need to be rebased onto the syscall | 11:23 |
| apw | trace events whenever that gets merged, and is a stop-gap. | 11:23 |
| apw | a leader is something or someone who leadsd | 11:23 |
| apw | the header arrives in your eyes first, so i can be called a leader | 11:23 |
| apw | english is stupid | 11:23 |
| apw | you get a similar confusion with rider, a rider can be someone who rides or it can be something which is carried with and is a bout something, like a limitation | 11:24 |
| hyperair | @_@ | 11:25 |
| hyperair | alright, point taken | 11:25 |
| apw | hyperair, apparently we have 12 meanings for leader | 11:25 |
| * hyperair groans | 11:25 | |
| apw | 1. a person or thing that leads. | 11:25 |
| apw | is the one i was using it in | 11:25 |
| hyperair | ah | 11:25 |
| apw | you don't need to remind me that english is massivly ambigious even to native speakers and a nightmare for the rest of the world :/ | 11:26 |
| hyperair | so anyway, what does ureadahead require that the sreadahead patch doesn't provide? | 11:26 |
| * hyperair considers himself to be a native speaker of english | 11:26 | |
| apw | it needs to know which binaries you are running | 11:26 |
| hyperair | ah i see | 11:27 |
| hyperair | well then off i go to hack the ureadahead patch to apply ontop of sreadahead's | 11:28 |
| apw | hyperair, why so? | 11:29 |
| hyperair | apw: i compile and run the zen kernels. they have the sreadahead patch applied. | 11:29 |
| hyperair | but not the ureadahead one | 11:29 |
| hyperair | maybe i'll go suggest to them | 11:30 |
| apw | well we are expecting to switch out sreadahead for ureadahead at the same time that the kernel updates | 11:30 |
| apw | and i assume xen is a patch on top of our main branch | 11:30 |
| apw | so they should switch when they rebase | 11:30 |
| hyperair | zen, not xen. | 11:31 |
| apw | ... oh yeah ... no idea :) | 11:31 |
| hyperair | heh | 11:31 |
| hyperair | and no, zen isn't a patch.. | 11:31 |
| apw | what the heck is zen | 11:31 |
| hyperair | it's a tree | 11:31 |
| hyperair | http://www.zen-kernel.org/ | 11:31 |
| hyperair | it's the mainline with all kinds of unapproved extras applied | 11:31 |
| hyperair | stuff like phc, bfs, tuxonice | 11:32 |
| hyperair | and they frequently pull from mainline | 11:32 |
| apw | gotcha | 11:32 |
| apw | so you'd want them to have 'both' so you can use that kerenl with ubuntu userspace i assume | 11:33 |
| hyperair | but of course | 11:33 |
| apw | sounds like fun for them :) | 11:33 |
| hyperair | heh | 11:33 |
| hyperair | well the ureadahead patch isn't much on top of the sreadahead patch, is it? | 11:33 |
| hyperair | i only had one conflict | 11:33 |
| hyperair | and that conflict was from stuff already added by sreadahead | 11:34 |
| apw | i think it produces more data for the existing sreadahead hook iirc | 11:34 |
| hyperair | yeah it does | 11:34 |
| apw | dunno how sreadahead would take that change | 11:34 |
| hyperair | isn't it a different ftrace? | 11:34 |
| apw | to be honest sreadahead has major issues, like its not aware of hdd ... so it makes things worse there | 11:34 |
| hyperair | agreed | 11:35 |
| hyperair | my boot up time is 2m 30s | 11:35 |
| hyperair | this is ridiculous | 11:35 |
| hyperair | readahead-list was way better | 11:35 |
| hyperair | why did we get rid of that? | 11:35 |
| apw | yeah ... it was ... and ureadahead is fixing that and doing better | 11:35 |
| apw | was where the majority were going, and probabally was wrong | 11:36 |
| hyperair | yeah, at least we don't need readahead-list wasting time setting up inotify hooks on every single file on the filesystem >_> | 11:36 |
| hyperair | there was quite some noise made re readahead-list's removal, but somebody said that sreadahead's packfile was equivalent if not better <_< | 11:36 |
| hyperair | and conveniently stifled out all the noise by invalidating said bug | 11:37 |
| hyperair | very elegant. | 11:37 |
| apw | heh ... sometimes you need to try things, find its wrong, and fix it | 11:40 |
| apw | i think thats what happened here | 11:40 |
| hyperair | heh i suppose =\ | 11:42 |
| hyperair | aw damnit it won't compile | 11:44 |
| Appiah | JanC and apw thanks for the explaination | 12:14 |
| * hyperair reverted every sreadahead commit on the list and then applied the ureadahead patch | 12:18 | |
| michLinuxGuy | Hi! | 14:31 |
| apw | s'up | 14:31 |
| michLinuxGuy | Question: How do I install an older pre-built kernel on Karmic. (Like the kernel used in Jaunty) ??? | 14:32 |
| michLinuxGuy | I am trying to troubleshoot a failing wireless adapter | 14:32 |
| apw | older kernels are available in the launchpad librarian, i blieve all of them are there | 14:32 |
| michLinuxGuy | Do I get to that from synaptic? Or can you give me a URL? | 14:33 |
| apw | you can get to the current ones at least here: https://edge.launchpad.net/ubuntu/+source/linux | 14:33 |
| michLinuxGuy | Thanks! | 14:34 |
| apw | this link looks to show you _all_ kernels ever: https://edge.launchpad.net/ubuntu/+source/linux/+publishinghistory | 14:34 |
| michLinuxGuy | I have a Linksys USB wireless adapter that won't connect now that I installed Karmic. It worked fine with Jaunty. I'm going to try the Jaunty kernel with my karmic installation. Does that sound like a good approach to diagnosing this? | 14:36 |
| apw | michLinuxGuy, yep ... what device is it inside? | 14:36 |
| michLinuxGuy | ID 13b1:000d Linksys WUSB54G Wireless Adapter | 14:37 |
| michLinuxGuy | I tried the adapter on another machine with karmic and it did work, but dropped and reconnected once. | 14:38 |
| apw | odd | 14:38 |
| michLinuxGuy | Yeah. This was with a clean install. I could try reinstalling, but I think I will try the older kernel first. | 14:39 |
| michLinuxGuy | The problem machine is an older HP laptop: ze4210 | 14:40 |
| michLinuxGuy | apw: Are the links you showed me source only? Is it possible to get a prebuilt .deb file with the kernel and modules? | 14:44 |
| apw | michLinuxGuy, binary packages appear to be there if you click trhough the build links for an architecture | 14:46 |
| michLinuxGuy | I guess I am not as smart as I thought I was. I can't quite find what I need to install an older kernel from binary. :( | 14:53 |
| michLinuxGuy | To install a binary kernel, do I just need an image .deb and a .deb containing the kernel modules? | 14:57 |
| === thunderstruck is now known as gnomefreak | ||
| apw | michLinuxGuy, the linux-image contains the whole kernel, if you have any binary drievers you also nead the linux-headers, and the generic headers the _all package which is only built on i386 | 15:06 |
| michLinuxGuy | apw: Thanks for all your help. | 15:10 |
| === bjf-afk is now known as bjf | ||
| michLinuxGuy | apw: I installed kernel linux-image-2.6.28-16-generic_2.6.28-16.55_i386.deb and my linksys USB wireless adapter started working again. Do you have advice on what I should do with this information? | 15:19 |
| apw | file a bug using ubuntu-bug when you are booted on the karmic broken kernel. include a dmesg from the working kernel | 15:21 |
| apw | and clearly mark that dmesg, and clearly indicate the version you found it does work | 15:21 |
| michLinuxGuy | apw: Thanks, I'll do that. One note: the symptom is it finds the access pt, but never connects and times out. I didn't see anything informative in the dmesg output about it. | 15:22 |
| apw | but having both tells us if the same driver picked up the device and the like | 15:24 |
| michLinuxGuy | apw: Okay - will do. Thanks! | 15:24 |
| michLinuxGuy | apw: I submitted a bug for the problem [Bug 472953]. Thanks again for your help with this. | 16:51 |

| tormod | cwillu, thanks, right, I guess that's the whole point of the PPA :) but there is some Ubuntu building stuff like a debian dir? | 22:03 |
| cwillu | can't speak to that, sorry :p | 22:05 |
| tormod | btw there is 2.6.32-rc6 now | 22:05 |
| tormod | is the daily ppa build exactly like the upstream "snapshot" or is it a pull from linus tree at some time of day? | 22:07 |
