[08:33] discussing kernel bugs goes in the "kernel development discussion" category, right? [08:37] Usually. [08:38] so how should i go about debugging an issue with a hotkey that apparently is kernel-level because input_events and acpi_listen both say nothing's going on when i press the key? === apw`` is now known as apw [09:37] there is something weird happening with the kernel source package... I get this --> http://rafb.net/p/hSVkME70.html [09:37] but some other people are not getting that problem [09:37] (im using "main server" in apt software sources config) [09:43] mnemo: You are better off fetching the linux source either from git, or with linux=2.6.28-7.20 for example. [09:44] but the git might contain some patches that are not in my binary right? because I assume a new package is generated automatically every time someting is commited to the git tree? [09:45] TheMuso: what you mean exactly when you say "use linux=2.6.28-7.20" ?? [09:45] mnemo: You use the source package name linux, and you are giving an exact version number, so apt-get doesn't get confused and look up the first partial match it finds. [09:46] mnemo: I don't know how the kernel team do PPA uploads, but what is in git now may not be in the binaries that are in the archive. [09:46] More to the point, I don't know how often they upload to PPAs etc. [09:46] ok, makes sense [09:47] but what would be the full apt-get command line for doing the linux=2.6.28-7.20 trick? [09:47] apt-get source linux=2.6.28-7.20 as of the latest upload from the kernel team in the archive. [09:48] how did you find that number? I mean if I want to do this again later on [09:48] mnemo: Best place to check is launchpad, http://launchpad.net/ubuntu/+source/linux [09:51] ok thanks [09:51] You're welcome. [09:55] * TheMuso sighs. Ok, that should be the final ports upload for now, and should get us binaries on most if not all ports architectures. [09:56] All arches would be nice, but there may yet be unknown FTBF issues on ia64, sparc, or hppa. [11:44] I'm working on the Jaunty LPIA alternate CD, and have run into issues with not being able to load the CD-ROM driver after first boot under KVM. It was suggested that this may be a missing kernel module in the udebs, but I'm not seeing much variance in the set of modules built between the regular kernel and the lpia kernel in the debian/d-i/modules directory. Could someone help me track down this issue, or redirect me to the appropriate foru [11:44] m? [12:58] What can I do to get a vmlinux file for my standard ubuntu kernel? [12:58] Do I have to rebuild the kernel and extract that file from the source tree? Or is there a way to extract a vmlinux out of a vmlinuz? [13:13] johan: It's just a gzipped vmlinux, I believe. [13:15] soren: google tells me there are no known tools to extract it [13:15] gzip? [13:15] I'd guess that the symbols are also stripped [13:15] johan: there are still enough symbols to load modules. [13:16] rtg: yes, but not enough to get useful information out of oprofile [13:17] other then the exported public symbols, then yes you are correct [13:17] there used to be linux-image-debug kernels just for that, but appears they're not updated any longer [13:18] johan: IIRC, Hardy is the last release that produced debug kernels [13:19] rtg: is there a reason they can't be built and put on ddeb.ubuntu.com for instance? [13:20] I think we determined that it was a lot of build/space overhead for little benefit. no one seemed to be using them. [13:23] it's pretty useful to have them for tools like systemtap/oprofile [15:29] nyargh! [15:29] the kernel's silly fd interfaces never cease to annoy me [15:30] they're implemented as streams, yet don't behave like streams [15:30] you can't just read part of the data into a buffer, it returns -EINVAL if the buffer is too small for the struct [15:31] but you can over-read multiple structs in one read [15:31] should so be a msgbuf instead === thunderstruck is now known as gnomefreak === KterinK is now known as dou213 === calc_ is now known as calc [21:18] hi rtg [21:23] Kano: you're on my todo list for tomorrow [21:23] * laga blinks [21:23] thats a tiny patch against the driver you already have, i tested it as external compile hack, it compiled [21:23] but the user with the webcam did not appear, all i can say it compiled [21:24] Kano: if it doesn't fix anything, then why bother [21:24] it fixes the compilation,the tiny patch i gave you in the last mail [21:24] i guess it could work [21:25] it was always the same abi change [21:25] so i guess the patch is correct
