| mase_work | hey guys , i am running into the same symptoms as https://bugs.launchpad.net/ubuntu/hardy/+source/linux/+bug/240071 on a fully up to date 8.04.2 server. It says a fix has been released but I can't see anywhere what the fix actually was and if that means it's been released as part of the regular update cycle of it need a special repository | 03:06 |
| ubot3 | Malone bug 240071 in linux "BUG: soft lockup - CPU#0 stuck for 11s!" [Undecided,Fix released] | 03:06 |
| mase_work | I was hoping someone could guide me as to how i can determine if I am hitting this same issue or if I have something different that just presents the same | 03:07 |
| cwillu | mase_work, that's an error, it's fixed in intrepid, somebody said they'd nominate it for hardy, but it looks like that didn't happen | 03:48 |
| cwillu | mase_work, you might be able to get away with simply installing intrepid's kernel packages though | 03:48 |
| cwillu | actually, ignore that | 03:48 |
| mase_work | ah ok. so i need to apply this patch normally | 03:50 |
| mase_work | manually rather | 03:50 |
| mase_work | cwillu: sorry this might seem like a stupid question, is it possible in launchpad to get a patch or a git commit id which i could use to grab the patch | 03:54 |
| cwillu | mase_work, sometimes, but in this case, I don't think so | 03:55 |
| cwillu | it looks like it was a "here's a new version with lots of stuff fixed, is your bug fixed?", without a specific patch in mind | 03:55 |
| === mcasadevall is now known as NCommander | ||
| mase_work | I see. Do you have any recommendations as to how best to deal with this ? | 04:00 |
| mase_work | should i revert to a previous kernel or move to a newer kernel ? | 04:00 |
| cwillu | move to a newer one is probably the best bet, you can just install the deb files for a later kernel image, they should Just Work. | 04:08 |
| mase_work | cwillu: so the intrepid-xen images are acceptable ? | 04:12 |
| cwillu | I would imagine s | 04:13 |
| cwillu | so | 04:13 |
| mase_work | ok thanks. I am using pygrub so i should be able to do it. Do you know if the vpcu=1 work around that is listed is likely to actually work ? | 04:14 |
| ZeroProg | hey guys im trying to learn some driver writing but am having trouble compiling and testing....is there an ubuntu doc for doing this? | 04:16 |
| ZeroProg | anybody in here | 04:43 |
| mase_work | yeh there is | 04:47 |
| mase_work | i just don't know the answer to your question sorry | 04:48 |
| mase_work | i could google around but i presume you have already tried that approach and been unsuccessful | 04:48 |
| ZeroProg | exactly | 04:48 |
| ZeroProg | i guess the best place to start would just be ubuntu kernel programming but i cant seem to find a tutorial | 04:49 |
| lifeless | its not an ubuntu specific thing | 04:50 |
| lifeless | look for linux kernel docs/tutorials | 04:50 |
| lifeless | rusty russell has done several tutorials at LCA for instance | 04:50 |
| ZeroProg | i have but after talking to people in #kernelnewbies and they said ubuntu is different | 04:51 |
| lifeless | Ubuntu takes the kernel and we add some patches and package it. Its still the same thing though in terms of writing code for it. | 04:52 |
| ZeroProg | yes but the source and headers and stuff is different is what i gather | 04:52 |
| lifeless | news to me | 04:52 |
| ZeroProg | i followed 3 tutorials to the letter and i still get the same errors about not finding linux/init.h | 04:52 |
| ZeroProg | the guys in the other channel said something about make-kpkg | 04:54 |
| lifeless | are you trying to build with the full kernel source locally? | 04:54 |
| lifeless | or using your installed kernel's headers? | 04:55 |
| ZeroProg | whatever i need to do to write drivers heh | 04:55 |
| lifeless | depends on what you're doin | 04:55 |
| lifeless | g | 04:55 |
| lifeless | but I can't give you a useful pointer unless you tell me *what you were trying* | 04:55 |
| ZeroProg | u mean like what type of driver? | 04:56 |
| lifeless | no | 04:56 |
| ZeroProg | oh ok | 04:56 |
| ZeroProg | i understand....i read these tutorials about what was needed to write drivers and the consensus was to download and build a kernel source | 04:56 |
| ZeroProg | so i followed the readme included with the source | 04:56 |
| ZeroProg | other tutorials said headers were sufficient but i still cant get ubuntu to recognize linux/init.h and the other includes | 04:57 |
| lifeless | ok, following the full source approach is easiest I think | 04:57 |
| lifeless | and the vanilla upstream kernel will build on Ubuntu | 04:57 |
| lifeless | in fact we use that for testing | 04:57 |
| ZeroProg | ok...is there perhaps a newb tutorial on downloading and installing that? | 04:58 |
| lifeless | sounds like you were following one | 04:58 |
| ZeroProg | yeah :/ | 04:58 |
| lifeless | so, I'd follow it. Do the full source one, not the headers package - that way you are guaranteed to have everything basically the same. | 04:59 |
| ZeroProg | ok | 04:59 |
| ZeroProg | thanks again | 04:59 |
| ZeroProg | where can i find that kernel | 05:04 |
| lifeless | http://kernel.org/ | 05:05 |
| ZeroProg | ohh ok i thought it was something specific my fault | 05:05 |
| ZeroProg | one last newb question for the night....how do u know its vanilla upstream | 05:06 |
| lifeless | if you get it from upstream :) | 05:11 |
| ZeroProg | lol is there an upstream section on the site? | 05:11 |
| mase_work | that is _the_ upstream | 05:13 |
| ZeroProg | jeez im confused...what makes it vanilla is that what its named? | 05:13 |
| mase_work | no | 05:13 |
| mase_work | vanilla just means no added patches | 05:13 |
| mase_work | its the tree that linus holds | 05:14 |
| mase_work | Ubuntu uses that then applies some added patches for various things | 05:15 |
| mase_work | and packages that up as the ubuntu kernel | 05:15 |
| mase_work | but for the most part they are the same | 05:15 |
| ZeroProg | ohhh ok | 05:15 |
| mase_work | the version on kernel.org is the unpackaged source version. | 05:16 |
| ZeroProg | alright im gonna leave before i ask anything else dumb thanks again | 05:16 |
| mase_work | ZeroProg: have you done much C programming before ? | 05:16 |
| ZeroProg | not on linux but yes | 05:16 |
| mase_work | ok cool. | 05:16 |
| mase_work | have fun | 05:17 |
| ZeroProg | haha ill try thanks | 05:17 |

| ikepanhc | hi smb | 12:01 |
| * apw waves to ikepanhc | 12:37 | |
| ikepanhc | hi apw | 12:47 |
| ikepanhc | have a question for you: bug 360966 | 12:48 |
| ubot3 | Malone bug 360966 in linux "bnx2x missing in initrd for install media" [Medium,Won't fix] https://launchpad.net/bugs/360966 | 12:48 |
| ikepanhc | could I set affect to initramfs-tools? | 12:48 |
| ogra | ikepanhc, more likely debian-installer | 12:49 |
| ikepanhc | ogra: you mean debian-installer makes the initrd? | 12:50 |
| ogra | initramfs-tools is only used on installed systems or in conjunction with casper for the live images | 12:50 |
| ogra | the alternate installer uses udebs ... ogasawara mentioned ./debian/d-i/modules/nic-modules, thats a udeb spec file | 12:51 |
| ikepanhc | oh, you are right | 12:51 |
| ogra | so its actually a linux issue ... d-i only uses the produced udeb | 12:52 |
| ikepanhc | I know what I am wrong, I test with a new kernel install | 12:53 |
| ikepanhc | thanks ogra | 12:54 |
| ikepanhc | ogra: but it is useless to send as Jaunty SRU, because we have released it | 12:55 |
| ogra | i'm not sure, it would require a d-i SRU as well i think, cjwatson could answer that | 12:56 |
| ikepanhc | so, could we assume this issue only affect him because he use NFS as rootfs? | 12:58 |
| ogra | well, he doesnt talk anout nfsroot | 12:59 |
| ogra | just that there is no network available | 12:59 |
| ikepanhc | The jaunty release kernel image contains the module he need, but he said he need the module when initrd. | 13:00 |
| ogra | right | 13:00 |
| apw | thanks ogra | 13:01 |
| ogra | but debian-installer uses the nic-modules udeb | 13:01 |
| ogra | in the netboot iso the udebs are included, in the normal d-i the udebs are loaded from CD | 13:01 |
| ogra | either way the driver needs to be in the udeb, no matter if you do a local or netboot install | 13:02 |
| ogra | indeed in case of nfsroot its more fatal :) | 13:03 |
| ikepanhc | Thanks ogra, I will check the d-i and udeb | 13:03 |
| ikepanhc | I assume he use NFS rootfs because he will have the module after mounting local rootfs | 13:04 |
| ikepanhc | Then I have to check if there is another net module missing | 13:04 |
| ogra | well, how would he do an nfsroot install without network ? :) | 13:05 |
| ikepanhc | ohoh, I forget this | 13:05 |
| ikepanhc | anyway, I re-open this bug :-D | 13:06 |
| ogra | if its for SRU talk to cjwatson first about the d-i situation | 13:07 |
| ogra | its pointless to add it to the udeb if d-i wont use it | 13:07 |
| ikepanhc | got it | 13:10 |
| ikepanhc | thanks ogra | 13:11 |
| apw | smb, you had a machine which worked, stopped working for a bit, and started working again on later kernels with no obvious changes in the area of the fault. what was the symptoms there? | 13:24 |
| smb | apw, You probably mean the acer which crashed when chaging the kernel data ro | 13:25 |
| apw | yeah thats the one... thanks | 13:26 |
| smb | It was the AA1, and crashed early on in the boot. | 13:26 |
| apw | you remember nigelp's sata issue. there his machine failed on -11.38 worked on either .39 or .40 and stopped again on .41 | 13:26 |
| apw | and yet there is no sata changes in that sequence | 13:26 |
| smb | using acpi=off made it working in most cases (strange enough) | 13:27 |
| smb | Sounds weird indeed | 13:27 |
| apw | nnng... | 13:27 |
| apw | another wierdy for sure | 13:27 |
| smb | how did nigelp's machine not work (mean the symptom there)? | 13:28 |
| apw | sata timeouts and panics (i believe he has flashing capslock syndrom at times) | 13:28 |
| smb | slightly different than the other as that was strictly locatable to the point of making the ro change (though sometimes you got killed by recursive stacktraces) | 13:30 |
| smb | Do we have any stactrace hint? | 13:30 |
| apw | nothing yet that i have seen. he is testing -proposed and latest mainline for me now | 13:33 |
| cking | apw: it's weird that we have not see this kind of issue on any other identical hardware | 13:48 |
| apw | i know ... very | 13:48 |
| cking | apw, I suspect the H/W is borked | 13:54 |
| apw | ok he has -proposed installed -12 kernel and is now happy | 13:54 |
| apw | explain that one to me | 13:54 |
| rimvis | hi, i have problem with aoetools who can help me? | 13:56 |
| smb | apw, random memory relocation and timing? | 13:56 |
| apw | smb, its cirtainly looking like that kind of thing ... very annoying to debug | 13:56 |
| smb | apw, You think a fully debug (kernel hacking) kernel might help? Unfortunately this often removes the race | 13:58 |
| apw | yeah not sure ... cirtainly intereested in getting the latest mainline tested there | 13:58 |
| apw | to see if its going to come back when he upgrades to karmic | 13:59 |
| apw | nigelp is with us now :) | 13:59 |
| apw | nigelp, so you have no problems now with the -proposed kernel ? | 13:59 |
| nigelp | apw, none of those SATA issues that showed up that I had to do irqpoll and all_generic_ide for. | 14:01 |
| apw | very perplexing | 14:01 |
| nigelp | the test that triggered it was downloading a CD image.. I've just downloaded 10 in a row; it never used to make it past 100Mb before. | 14:02 |
| smb | It will be interesting to see how the -13 kernel that will be in -proposed soon fares | 14:02 |
| smb | If that fails it is definitely weirdness time | 14:02 |
| apw | nigelp, what was your disk controller? | 14:04 |
| apw | yeah a quick review of the changes between where it did not work before and the -proposed kernel isn't showing anything i would expect to help you | 14:07 |
| nigelp | apw, sorry, being ignorant. How do I find out what my disk controller is? | 14:09 |
| apw | lspci | grep -i sata | 14:09 |
| apw | might do the trick | 14:09 |
| nigelp | apw, is this what you're looking for? ATI Technologies Inc IXP SB400 IDE Controller (rev 80) | 14:10 |
| apw | yep | 14:11 |
| apw | nigelp, we need to get all this data into the same bug. if you have one with support lets get that out of them, else we need a new one | 14:12 |
| apw | i can imaging you want to get some work done now its working! but if you have a chance later to test the mainline kernel i pointed you to that would help. and get that info into the bug too | 14:13 |
| apw | then let me have the number when you have it | 14:14 |
| nigelp | apw, let me ask shang if he opened one. | 14:14 |
| === sconklin-gone is now known as sconklin | ||
| nigelp | apw, support say its the same bug as: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/206635 | 14:23 |

| * apw pokes ubot3 | 14:24 | |
| apw | but that bug is duplicate of a bug which was fixed in intrepid and jaunty | 14:25 |
| nigelp | ok.. so time for a new one? | 14:25 |
| apw | way back in feb. so ... if you are seeing it now its either a new one, or that one was not fixed | 14:25 |
| apw | for now i would open your own bug, and add your info there, if it _is_ dup we can dup it later | 14:26 |

| apw | nigelp, can you subscribe me to the bug when it exists | 15:06 |
| nigelp | apw, sure | 15:07 |
| apw | smb, for hardy do we use linux-image-2.6.24 still? | 16:34 |
| smb_tp | apw, Hardy is 2.6.24, yes | 16:43 |
| smb_tp | or do you mean the naming? | 16:43 |
| apw | i mean do we use linux or something else for bugs there | 16:43 |
| Kano | hi apw , do you update the karmic kernel now and not rtg? | 16:44 |
| apw | our team is responsible for it, i am handling the rebases for a bit while rtg is off doing other things | 16:44 |
| smb_tp | apw, Hardy uses linux | 16:44 |
| apw | smb_tp, thanksk ... and when did you go back to _tp? | 16:45 |
| smb_tp | apw, When I disconnected and irc still thinks me is there | 16:45 |
| === smb_tp is now known as smb | ||
| apw | smb, heh ... still not reset your router at midnight then | 16:46 |
| smb | apw, No, you should poke me :) | 16:46 |
| smb | apw, BTW, you can see what label to use in debian/changelog. It was linux-source-x.y.z before hardy | 16:48 |
| apw | ahh before hardy. good | 16:48 |
| Kano | apw: are you interested in an aufs2 patch | 17:11 |
| apw | an updated one for karmic kernel? | 17:11 |
| Kano | yes | 17:12 |
| Kano | i tested it even with your live iso | 17:12 |
| Kano | cjwatson tries to use unionfs-fuse but his approach does not boot | 17:12 |
| apw | send it over. we are looking at vfs-union mount right now for the live cd's but should that not be possible the aufs patch would be a good fallback | 17:13 |
| Kano | i needed to update it as you removed aufs completely | 17:14 |
| Kano | http://kanotix.com/files/kernel/unused-patches/2.6.30-ubuntu-aufs2.patch.bz2 | 17:14 |
| Kano | thats the new one | 17:14 |
| Kano | also i would like to see a patch which removes the usb ids from rt2500usb which are also in rt73usb | 17:15 |
| Kano | because i had 2 users with problems where rt2500usb was loaded and nothing worked | 17:15 |
| Kano | 4 ids are in both drivers | 17:16 |
| apw | we need to get those ids listed in a bug i recon | 17:17 |
| Kano | it is easy to get em | 17:17 |
| Kano | (/sbin/modinfo -F alias rt73usb;/sbin/modinfo -F alias rt2500usb)|sort|uniq -d | 17:20 |
| Kano | /sbin/modinfo -F alias rt73usb rt2500usb|sort|uniq -d | 17:26 |
| Kano | thats even shorter... | 17:26 |
| Kano | apw: also how about enabling the lzma options for smaller kernel size | 17:27 |
| apw | for compressed kernels? | 17:28 |
| Kano | you could even update update-initramfs and use lzma if the kernel config has the needed setting | 17:28 |
| apw | how well tested is that | 17:28 |
| Kano | sure | 17:28 |
| Kano | if you dont enable nobody tests it | 17:28 |
| Kano | it is one of the major points for 2.6.30 | 17:28 |
| Kano | i hope that squashfs will get lzma too because it is now inside the kernel | 17:29 |
| apw | lzma was the one which had poor rsync behaviour i think? making it near useless for CD's | 17:30 |
| apw | iirc | 17:30 |
| Kano | nope | 17:30 |
| Kano | did you never hear of lzma patches for squashfs | 17:30 |
| Kano | http://www.squashfs-lzma.org/ | 17:30 |
| Kano | slax used it | 17:31 |
| amitk | apw: ack re: lzma + rsync not being friends | 17:32 |
| Kano | tar.lzma is now the default for slackware | 17:32 |
| Kano | so many use it now | 17:33 |
| apw | as i remember the size savings are impressive and would be desirable for our live images, but a problem for the QA process as its non-rsyncable | 17:33 |
| Kano | i dont get it | 17:33 |
| Kano | rsync is independent of the data | 17:35 |
| === bjf_ is now known as bjf | ||
| bjf | *** There will be an Ubuntu Kernel Team meeting on #ubuntu-meeting at the top of the hour. | 17:50 |
| apw | Kano, right but the data needs to be similar between images to allow rsync to be efficient | 17:55 |
| apw | and lzma produces images which are completely different for a small change in the contents | 17:56 |
| Kano | well squashfs stores files basically always the same | 17:56 |
| Kano | should not matter that way | 17:56 |
| apw | bjf, good idea to announce here | 17:57 |
| Kano | did you really test squashfs-lzma or pure lzma? | 17:57 |
| apw | seems it does, from the testing that foundations has done | 17:57 |
| apw | so they tell me yes | 17:57 |
