| edgimar_ | Could anyone give me tips on debugging a kern.log entry -- I am seeing a "bad: scheduling from the idle thread; Pid: 0, comm: swapper Not tainted 2.6.32-29-generic #58-Ubuntu; Call Trace: ..." about every 2-3 microseconds -- and the logs (kern.log, syslog, and messages) are getting HUGE (as in around 20GB each). | 11:55 |
| edgimar_ | Here's a snippet from the syslog which could be relevant: http://pastebin.com/m3tUashf | 12:03 |
| kristian-aalborg | https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel | 13:00 |
| kristian-aalborg | the dependencies you get with the command listed here (sudo apt-get build-dep linux-image-$(uname -r)) are way too heavy - who's to "blame"? | 13:01 |
| kristian-aalborg | not the quatiation marks, nobody is to blame of course :) but this could probably be fixed | 13:02 |

| AnAnt | Hello, anyone knows what happened to open_sem function in kernel ? | 14:15 |
| AnAnt | was it replaced by something else ? | 14:15 |
| kristian-aalborg | there should be some kind of lottery where you got a ticket each time a kernel build failed ;) | 14:24 |
| AnAnt | sorry, I meant DECLARE_MUTEX | 14:28 |
| kamal | kristian-aalborg: I'd be sooooo rich. ;-) | 14:29 |
| kristian-aalborg | speaking of errors, ah few is nothing to worry about, right? | 14:36 |
| kamal | kristian-aalborg: actually, any *error* will stop your build dead. perhaps you just mean warnings? post an example of one of the "errors" you're worried about. | 14:39 |
| kristian-aalborg | kamal: yup, I was thinking warnings | 14:39 |
| kamal | kristian-aalborg: yeah, the kernel build spews lots and lots of warnings for sure... don't worry about them, as long as your build keeps rolling along. | 14:40 |
| kristian-aalborg | it would be cool if you could just upload your .config and then get the .deb | 14:50 |
| kristian-aalborg | bugger, it quit again | 15:07 |
| kristian-aalborg | I got it to build finally, installing now :) | 15:24 |
| kristian-aalborg | hurm, dependency problems | 15:49 |
| kamal | kristian-aalborg: which .deb(s) did you build and install? If you build "binary-headers" and "binary-generic" you should end up with 3 .debs (one linux-image-...deb and two linux-headers-...deb). That set of 3 .debs should be installed as a group. That help any? | 16:03 |
| * kamal notes that the wiki page https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel fails to mention binary-headers :-( | 16:04 | |
| kristian-aalborg | kamal: likely | 16:06 |
| kamal | kristian-aalborg: try this instead of just 'binary-generic': fakeroot debian/rules binary-headers binary-generic | 16:07 |
| kamal | then verify that you end up with 3 .debs -- dpkg -i them all together -- should help. I'll see about fixing the wiki. | 16:07 |
| kristian-aalborg | kamal I was following some instructions I got on this channel recently more than the wiki | 16:08 |
| * kristian-aalborg facepalmed and got some more coffee... is ready again now | 16:13 | |
| kamal | kristian-aalborg: oh yes, I should have mentioned... strong coffee is another prerequisite for the kernel build ;-) | 16:14 |
| kristian-aalborg | hurm, I actually only have two .debs - linux-headers and linux-image | 16:17 |
| kristian-aalborg | I got the missing modules error, then tried again with the ignore-missing (or such) flag | 16:17 |
| kamal | kristian-aalborg: ignoring module checks and abi is fine. I suspect you need that third .deb, which you'll get if you build 'binary-headers' | 16:18 |
| kamal | FYI, the complete set of 3 will look something like this: | 16:19 |
| kamal | linux-headers-2.6.38-6_2.6.38-6.34_all.deb | 16:19 |
| kamal | linux-headers-2.6.38-6-generic_2.6.38-6.34_amd64.deb | 16:19 |
| kamal | linux-image-2.6.38-6-generic_2.6.38-6.34_amd64.deb | 16:19 |
| kristian-aalborg | ok | 16:20 |
| kristian-aalborg | so, fakeroot debian/rules binary-headers | 16:20 |
| kamal | kristian-aalborg: yes | 16:20 |
| kristian-aalborg | how "heavy" is that, compared to the others? | 16:21 |
| kamal | very light | 16:21 |
| kristian-aalborg | cool | 16:21 |
| kristian-aalborg | who's doing the wiki, btw? | 16:21 |
| kamal | the wiki pages are maintained by the Ubuntu kernel team (and the community in general) | 16:22 |
| kristian-aalborg | it could use a little touching up, although I really like that it's rather short | 16:23 |
| kristian-aalborg | btw, ubuntu.com is looking real pro these days - probably the neatest OS website I have seen | 16:24 |
| kamal | kristian-aalborg: there have been various versions of the "how to build a kernel" instructions, some too long, some too short. its tough to come up with one document that works well for everybody. | 16:24 |
| kristian-aalborg | sure | 16:24 |
| kristian-aalborg | there's just a point where it gets so detailed that users can be intimidated to never try, imo | 16:25 |
| kamal | kristian-aalborg: absolutely true -- I like the "short instructions" for that reason, but perhaps they've been trimmed down just a bit too much. | 16:26 |
| kristian-aalborg | yes, it is a very hard balance to find | 16:28 |
| kristian-aalborg | there's also a point where you keep users in the dark by insisting that they do things the "easy" way | 16:30 |
| kristian-aalborg | something is happening now... this might work | 16:33 |
| kristian-aalborg | kamal: using apmd? | 16:37 |
| kamal | kristian-aalborg: nope | 16:38 |
| kristian-aalborg | erm, my new kernel reboots the box | 16:39 |
| kristian-aalborg | also in recovery mode | 16:39 |
| kamal | kristian-aalborg: did you apply any patches, or is the source unmodified? What version exactly did you build, and what Ubuntu version are you running? | 16:41 |
| kristian-aalborg | I'm running 10.4 - I did a make localmodconfig and then tweaked it | 16:41 |
| kamal | kristian-aalborg: I suggest that you try building a plain unmodified kernel as a sanity check. | 16:41 |
| kristian-aalborg | I got it via git | 16:42 |
| kristian-aalborg | yeah, that's probably what I should do | 16:42 |
| kristian-aalborg | something weird is that I called it ~custom, but it seems to have installed as -generic | 16:44 |
| kamal | kristian-aalborg: so are you building the ubuntu-lucid (10.04) kernel on a lucid system, and then installing it on a lucid system? Or something more fancy (i.e. installing a newer-than-lucid kernel on a lucid system?) | 16:45 |
| kristian-aalborg | I'm building on Lubuntu 10.4 which should be the same, then installing on 10.4 | 16:46 |
| kristian-aalborg | wut | 16:47 |
| kristian-aalborg | aptitude wants to install tzdata and similar things | 16:47 |
| kamal | kristian-aalborg: ok, nothing too fancy then. I don't understand what you mean by "called it ~custom" vs. "installed as" though... Sounds like you modified debian{.master?}/changelog and didn't get the result you expected. post the specifics if you need help unraveling that. | 16:48 |
| kristian-aalborg | might fix things... lemme see | 16:48 |
| kamal | kristian-aalborg: tzdata gets updated often -- probably not related to your kernel build/reboot issue. | 16:48 |
| kristian-aalborg | yeah, I was thinking of BzImage | 16:49 |
| kristian-aalborg | I edited debian/changelog to have a name that'd be different from my other kernels | 16:49 |
| kamal | kristian-aalborg: good plan, but ... | 16:49 |
| kristian-aalborg | this reflects in the names of my .debs, so weird it's not showing upon install | 16:50 |
| kamal | kristian-aalborg: note that debian/changelog gets overwritten (copied from) debian.master/changelog during the "fakeroot debian/rules clean" phase ... | 16:50 |
| kristian-aalborg | I did it before | 16:50 |
| kamal | kristian-aalborg: I'd say, double-check debian/changelog *now* to make sure it still has your ~custom tag in there -- does it? | 16:51 |
| kristian-aalborg | one moment, I have to fire up another pc then | 16:51 |
| kamal | kristian-aalborg: oh wait... do you mean just that you expected to see "~custom" in the GRUB boot loader menu? it doesn't show it there (sadly)! | 16:52 |
| kristian-aalborg | ah, that's okay | 16:52 |
| kamal | kristian-aalborg: yeah, it shows up in 'uname -a' (but it sounds like you're rebooting/crashing long before getting to a login prompt, yes?) | 16:53 |
| kristian-aalborg | yes | 16:53 |
| kamal | kristian-aalborg: likely all is fine then -- when you build your "unmodified" test kernel, you may want to go ahead and *still* mark it with a special version string, just so you can verify that its really your kernel with 'uname -a' once you do get it to boot. | 16:54 |
| kamal | kristian-aalborg: I often build test kernels with a "~unchanged" version string addition. | 16:54 |
| kristian-aalborg | I fooled around with dpkt and apt-get to try to "fix" the .deb that would not install | 16:55 |
| kristian-aalborg | I seem to have locked linux-generic in the process, unwise as I am | 16:56 |
| kamal | kristian-aalborg: I don't know what state you're in there, but apt-get install -f may help (or at least tell you what the problem is). | 17:01 |
| kristian-aalborg | they say "dependency hell" as if there is a "dependency heaven"... sigh | 17:07 |
| kristian-aalborg | I'm wondering... since this is from git, could it be partly unmet by the repos? | 17:16 |
| kamal | kristian-aalborg: unlikely -- the git repo's "master" branch should always produce a kernel that builds and installs properly. | 17:17 |
| kristian-aalborg | ok | 17:17 |
| kamal | kristian-aalborg: I wonder if you have some leftover bits installed from your first failed installs. try this: | 17:19 |
| kamal | dpkg -l | grep "~custom" | 17:19 |
| kamal | this should list all packages that you have installed which have "~custom" in their name | 17:19 |
| kristian-aalborg | I still have all of it | 17:20 |
| hyperair | kristian-aalborg: dependency issues? how about a paste of the errors? | 17:20 |
| kristian-aalborg | hi hyperair | 17:20 |
| hyperair | hi | 17:20 |
| hyperair | so how about pastebinning your errors | 17:20 |
| kristian-aalborg | these issues were my own fault... I was missing a .deb | 17:21 |
| kamal | you could remove (with dpkg) all of your "~custom" packages to clean up. | 17:21 |
| kristian-aalborg | I'm trying once more now the dependencies seem fixed | 17:23 |
| kristian-aalborg | ah, enough for now | 18:05 |
| kristian-aalborg | but thanks for helping out, ppl... I believe I will have this sorted in the foreseeable future | 18:08 |
| * kristian-aalborg is back | 20:19 | |
| kristian-aalborg | kamal: ping | 20:20 |
| kristian-aalborg | fakeroot debian/rules clean | 20:21 |
| kristian-aalborg | fakeroot debian/rules binary-generic | 20:21 |
| kristian-aalborg | only these two commands needed for the "sanity check"? | 20:21 |
| Kano | hi, would somebody update kernel-wedge to be newer than current squeeze/sid version? | 20:29 |
| === ogra is now known as Guest23759 | ||
| kamal | kristian-aalborg: I always do: fakeroot debian/rules binary-headers binary-generic (building and installing the headers along with image is quick enough, and never hurts) | 20:48 |
| kristian-aalborg | I'll do that as well, then... although not in that order | 20:51 |
| kristian-aalborg | btw the system I'm building on is Lubuntu 10.4, not Ubuntu... but should not matter, I think | 20:52 |
