| maco | discussing kernel bugs goes in the "kernel development discussion" category, right? | 08:33 |
|---|---|---|
| soren | Usually. | 08:37 |
| maco | 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? | 08:38 |

| mnemo | there is something weird happening with the kernel source package... I get this --> http://rafb.net/p/hSVkME70.html | 09:37 |
| mnemo | but some other people are not getting that problem | 09:37 |
| mnemo | (im using "main server" in apt software sources config) | 09:37 |
| TheMuso | mnemo: You are better off fetching the linux source either from git, or with linux=2.6.28-7.20 for example. | 09:43 |
| mnemo | 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? | 09:44 |
| mnemo | TheMuso: what you mean exactly when you say "use linux=2.6.28-7.20" ?? | 09:45 |
| TheMuso | 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. | 09:45 |
| TheMuso | 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 |
| TheMuso | More to the point, I don't know how often they upload to PPAs etc. | 09:46 |
| mnemo | ok, makes sense | 09:46 |
| mnemo | but what would be the full apt-get command line for doing the linux=2.6.28-7.20 trick? | 09:47 |
| TheMuso | apt-get source linux=2.6.28-7.20 as of the latest upload from the kernel team in the archive. | 09:47 |
| mnemo | how did you find that number? I mean if I want to do this again later on | 09:48 |
| TheMuso | mnemo: Best place to check is launchpad, http://launchpad.net/ubuntu/+source/linux | 09:48 |
| mnemo | ok thanks | 09:51 |
| TheMuso | You're welcome. | 09:51 |
| * TheMuso sighs. Ok, that should be the final ports upload for now, and should get us binaries on most if not all ports architectures. | 09:55 | |
| TheMuso | All arches would be nice, but there may yet be unknown FTBF issues on ia64, sparc, or hppa. | 09:56 |
| persia | 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 |

| johan | What can I do to get a vmlinux file for my standard ubuntu kernel? | 12:58 |
| johan | 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? | 12:58 |
| soren | johan: It's just a gzipped vmlinux, I believe. | 13:13 |
| johan | soren: google tells me there are no known tools to extract it | 13:15 |
| soren | gzip? | 13:15 |
| johan | I'd guess that the symbols are also stripped | 13:15 |
| rtg | johan: there are still enough symbols to load modules. | 13:15 |
| johan | rtg: yes, but not enough to get useful information out of oprofile | 13:16 |
| rtg | other then the exported public symbols, then yes you are correct | 13:17 |
| johan | there used to be linux-image-debug kernels just for that, but appears they're not updated any longer | 13:17 |
| rtg | johan: IIRC, Hardy is the last release that produced debug kernels | 13:18 |
| johan | rtg: is there a reason they can't be built and put on ddeb.ubuntu.com for instance? | 13:19 |
| rtg | I think we determined that it was a lot of build/space overhead for little benefit. no one seemed to be using them. | 13:20 |
| johan | it's pretty useful to have them for tools like systemtap/oprofile | 13:23 |
| Keybuk | nyargh! | 15:29 |
| Keybuk | the kernel's silly fd interfaces never cease to annoy me | 15:29 |
| Keybuk | they're implemented as streams, yet don't behave like streams | 15:30 |
| Keybuk | you can't just read part of the data into a buffer, it returns -EINVAL if the buffer is too small for the struct | 15:30 |
| Keybuk | but you can over-read multiple structs in one read | 15:31 |
| Keybuk | should so be a msgbuf instead | 15:31 |

| Kano | hi rtg | 21:18 |
| rtg | Kano: you're on my todo list for tomorrow | 21:23 |
| * laga blinks | 21:23 | |
| Kano | thats a tiny patch against the driver you already have, i tested it as external compile hack, it compiled | 21:23 |
| Kano | but the user with the webcam did not appear, all i can say it compiled | 21:23 |
| rtg | Kano: if it doesn't fix anything, then why bother | 21:24 |
| Kano | it fixes the compilation,the tiny patch i gave you in the last mail | 21:24 |
| Kano | i guess it could work | 21:24 |
| Kano | it was always the same abi change | 21:25 |
| Kano | so i guess the patch is correct | 21:25 |
