| mfilipe | hello! I want compile a custom kernel with generic-pae config but the https://help.ubuntu.com/community/Kernel/Compile doesn't help :( | 06:53 |
|---|---|---|
| mfilipe | how do I do this? I only compile a custom kernel same config of generic-pae | 06:54 |
| mfilipe | for start | 06:54 |
| mfilipe | after I want apply a custom patch but I need apply with patch program or is there any way more organized? | 06:55 |
| mfilipe | I see that kernel-package has the --apply-patches but I don't know if it works with custom patch | 06:55 |
| mfilipe | I tried extract the /usr/src/linux-source-2.6.38.tar.bz2, copied the config of generic-pae in /boot and compile with make-kpkg, but I always get kernel panic | 06:58 |
| === smb` is now known as smb | ||
| smb | mfilipe, https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel might help more. | 08:27 |
| mfilipe | smb, it is very confuse :( | 08:29 |
| mfilipe | I see tree ways to compile kernel: (1) using commands of kernel vanilla, (2) debian/rules and (3) kernel-package | 08:30 |
| mfilipe | some people say that kernel-package is the better solution | 08:30 |
| mfilipe | but when I compile my kernel with it, I get kernel panic | 08:31 |
| mfilipe | I will try with debian/rules | 08:31 |
| smb | Not if you want a kernel compiled as the provided one. Then dpkg / debian is the way to go. Everything else either has not the whole packaging or is not too well tested (we don'T use kernel-package) | 08:32 |
| mfilipe | smb, the better way to apply a patch is in kernel source with patch command or is there a way more organized? | 08:40 |
| smb | mfilipe, For just applying the change patch is the way to do it. And the simplest | 08:42 |
| mfilipe | thanks a lot for your help! :) | 08:42 |
| smb | Usually "patch -p1 < <source file>" | 08:43 |

| mfilipe | hello! I want apply a patch in generic-pae. So, how do I do to create a kernel called i915patch using debian/rules based in generic-pae? | 14:00 |
| smb | mfilipe, You can modify the version number in debian.master/changelog | 14:01 |
| smb | So on the first line | 14:01 |
| tgardner | mfilipe, everything you need to know is somewhere in here: https://wiki.ubuntu.com/Kernel | 14:01 |
| smb | change 2.6.x-y.z -> 2.6.x-y.6+i915patch | 14:01 |
| smb | err last 6 should be z | 14:02 |
| tgardner | ogasawara, did you ever find the armel build problem with oneiric? I rebased to -rc6 last night and pushed to master-next. | 14:04 |
| ogasawara | tgardner: I've finally been able to reproduce it on kakadu. It's basically because the compiler is optimizing a loop in megaraid_sas into a divmod call, but the error message isn't verbose enough to point out where, so I'm still hunting it down. | 14:06 |
| tgardner | ogasawara, has is struck you that kakadu is vaguely scatological ? | 14:08 |
| ogasawara | tgardner: hehe, not till you mentioned it :) | 14:08 |
| tgardner | ogasawara, now I've ruined your mind with an idea :) | 14:09 |
| * smb thinks he might ask tgardner whatever that means over a beer... | 14:09 | |
| tgardner | smb, giyf | 14:10 |
| smb | wtfmgiyf | 14:12 |
| ogasawara | heh | 14:12 |
| ogasawara | smb: google is your friend | 14:12 |
| smb | ogasawara, Heh, ok. Thanks. :) | 14:13 |
| smb | Usually I ask leo whenever our leader comes up with a even more mystical attribute for a release... | 14:14 |
| smb | Ok, so wikipedia knew it... :-P | 14:16 |
| ogra_ | tgardner, armel doesnt build atm, gcc issues that cause apt to segfault | 14:16 |
| ogra_ | dont even try :) | 14:16 |

| mfilipe | smb, thanks man! :) | 14:18 |
| tgardner | ogra_, ok. oneiric _is_ getting quite aways into the build but we're encountering a missing symbol error. We're not gonna worry about it too much for awhile. | 14:18 |
| ogra_ | tgardner, ah | 14:18 |
| ogra_ | well, i dont expect image builds before A1 | 14:19 |
| ogra_ | tgardner, btw, would you mind bringing my ultra small wlan stick to UDS ? i forgot to claim it back last time | 14:19 |
| tgardner | ogra_, hmm, its so small that I haven't seen it in awhile. | 14:21 |
| tgardner | I'll look around for it | 14:21 |
| tgardner | that the problem with thos itty bitty gizmos. they are easily lost | 14:21 |
| ogra_ | hehe, or forgotten :) | 14:21 |
| tgardner | well, that too | 14:21 |

| ogasawara | tgardner: don't suppose we'll ever get armel chroots on tangerine for oneiric? | 15:18 |
| tgardner | ogasawara, hrmph. I can't even get them working reliably for natty. | 15:18 |
| tgardner | not on a lucid host, that is. | 15:18 |
| ogasawara | tgardner: I figured as much, I won't hold my breath | 15:19 |
| tgardner | ogasawara, I guess we'll just have to stick with cross compiling for now | 15:19 |
| bjf | JFo, i'm going to edit: https://wiki.ubuntu.com/Kernel/BugTriage/BugStates, feel free to revert my changes if you feel them inappropriate | 15:21 |
| tgardner | ogasawara, one thing we could consider is upgrading tangerine to natty. that would at least give you a natty armel schroot. alternatively, I could spend some serious time with slangasek whilst in Budapest to see if we can figure out the Lucid host issues. | 15:24 |
| bjf | JFo, i take that back, i made no changes, i'm unhappy with the page but not sure how to "fix" it | 15:28 |
| ogasawara | tgardner: nah, cross compiling should be fine, it's just unfortunately not triggering the gcc error at the moment | 15:29 |
| * ogasawara back in 20 | 15:36 | |
| JFo | bjf, I feel the same | 15:40 |
| JFo | :-/ | 15:40 |
| JFo | been trying to figure out how best to address it | 15:40 |
| JFo | but not making much in the way of progress | 15:40 |
| bjf | JFo, i'll send email with my thoughts, mostly what I don't like about it | 15:40 |
| JFo | sounds good | 15:41 |
| JFo | I'll respond with some of what I have been thinking of as well | 15:41 |
| JFo | maybe we can figure it out | 15:41 |
| Kano | hi, is it possible to get 32+64 bit mainline kernel for 39rc6 | 16:11 |
| Kano | since rc5 32 bit is not available | 16:11 |
| Kano | it can not be that compilcated to change the config in order to skip that stupid module that does not build | 16:12 |
| Kano | since 20th april only 64 bit is there | 16:13 |
| Kano | 2 weeks for a config change? | 16:13 |
| tgardner | Kano, whats the config option that isn't building. I guess we don't check the success of the daily crack builds very often. | 16:22 |
| Kano | maybe look at the log | 16:23 |
| JFo | I would have expected you had done that given your statement | 16:24 |
| Kano | olpc_dcon | 16:26 |
| Kano | fails, the option should not be that hard to find | 16:26 |
| tgardner | CONFIG_FB_OLPC_DCON ? | 16:27 |
| Kano | looks reasonable | 16:28 |
| apw | tgardner, turning off those things is normally done via the 'adhoc' patches | 16:32 |
| apw | which are based on the bust version of the file | 16:32 |
| apw | there is one for another of the files in that driver | 16:33 |
| tgardner | apw, looks like we've a patch in the ubuntu repo that include delay.h | 16:33 |
| bjf | JFo, wiki page rant sent | 16:33 |
| apw | adding the checksum to the patch for that additioanl file should do the trick i think | 16:33 |
| apw | tgardner, ok i'll look at switching the adhoc to that then | 16:34 |
| tgardner | apw, there is already a 0004-DISABLE-olpc.patch | 16:34 |
| apw | yeah thats dependant on a file which seems to have gotten fixed | 16:34 |
| apw | tgardner, i'll widen it to all the files in that driver or something | 16:35 |
| tgardner | apw, cool. its your baby now. | 16:35 |
| mfilipe | anyone has the processor intel iX? If answer yes, what is the temperature when it compiling kernel? | 16:46 |
| mfilipe | it is compiling kernel* | 16:46 |
| Kano | there are iX cpus with 3 or 4 numbers | 16:47 |
| mfilipe | I'm using intel i5 560M and the temperature is 84C when compile kernel | 16:48 |
| smb | mfilipe, The kernel compile surely tests how well your cooling works as it uses all cores | 16:48 |
| smb | 84 is surely not good | 16:49 |
| mfilipe | it is a mobile version | 16:50 |
| mfilipe | i'm compiling with --jobs=4 (make-kpkg) | 16:50 |
| mfilipe | smb, i use a thinkpad with cooler control through software (thinkfan) | 16:52 |
| smb | From personal experience compiling on a laptop usually causes high temperature. I would probably try to limit the upper frequence though it takes longer then | 16:52 |
| JFo | bjf, I think your explanation clarifies what I was worried about and provides a better way forward than what I had. I agree completely. | 16:53 |
| mfilipe | the cooler is running with disengaged level | 16:53 |
| mfilipe | hehe | 16:53 |
| bjf | JFo, i'm wondering if i should pass that around to a larger audience as a general comment on our wiki pages | 16:54 |
| JFo | I think so. It would definitely benefit imo | 16:54 |
| smb | mfilipe, Well disabling fans and running cpu intensive tasks is a good recipe for meltdown.. :-P | 16:54 |
| mfilipe | lol | 16:55 |
| mfilipe | but disengaged level is the extreme level of cooler... it is running with ~5800 RPM | 16:55 |
| smb | ah, so the wording is a bit misleading | 16:56 |
| === jj-afk is now known as jjohansen | ||
| apw | tgardner, ok rebuilding the last mainline tag to see if that fixes things | 17:21 |
| tgardner | apw, kano thanks you | 17:22 |
| Kano | would be nice for oss testing | 17:22 |
| Kano | a new kernel | 17:22 |
| Kano | for userspace i have got already scripts | 17:23 |
| jgould | I installed a new kernel .deb (and the header.debs) Now none of my modules are working. for the life of me I can't recall how to complie the modules for the new kernel | 17:26 |
| Kano | if you try .39 kernel you may need to patch em | 17:27 |
| Kano | which modules do you need | 17:27 |
| jgould | ndiswrapper, plymouth for srue | 17:28 |
| Kano | plymouth has no module | 17:28 |
| Kano | but ndiswrapper was a kernel patch, logically you need that now external | 17:28 |
| apw | jgould, it would depend which kernel you are installing | 17:28 |
| jgould | 2.6.39-999 | 17:28 |
| apw | jgould, yeah so thats mainline and doesn't include ndiswrapper, thats an ubuntu add on and those are not ubuntu kernels | 17:29 |
| jgould | I can't use the stock .38-8-generic | 17:29 |
| apw | jgould, why so ? | 17:30 |
| jgould | It contains the bug that affects the i915 graphic chipset | 17:30 |
| apw | which bug is that? | 17:30 |
| apw | is the 38-9 kernel in -proposed affected ? | 17:30 |
| jgould | https://bugzilla.redhat.com/show_bug.cgi?id=669489 | 17:30 |
| ubot2 | bugzilla.redhat.com bug 669489 in kernel "Include ACPI _DSM index and label support" [High,New] | 17:30 |
| jgould | apw: you lost me with -proposed | 17:32 |
| jgould | I'm just coming back to Ubuntu after about 10 years away from linux | 17:32 |
| apw | there is a proposed pocket, this contains the likely next updates, and does currently contain a kernel update | 17:32 |
| apw | jgould, but either way you won't find an ndiswrapper for the mainline kernels, as they don't include ubuntu modules | 17:33 |
| jgould | damn | 17:34 |
| jgould | fucking intel hardware | 17:37 |
| apw | jgould, worth testing both the proposed kernel and the preproposed on as both have a lot of stable updates | 17:37 |
| apw | https://wiki.ubuntu.com/Testing/EnableProposed | 17:37 |
| apw | ^^ for the proposed kernels | 17:37 |
| apw | https://launchpad.net/~kernel-ppa/+archive/pre-proposed | 17:38 |

| apw | jgould, if there is no ubuntu bug for that filed, please file one and link it to the redhat one | 17:42 |
| apw | tgardner, am i expecting brcm80211 to work at all? i just noticed i am using it on this machine, rather unexpectedly | 17:43 |
| Kano | bye | 17:43 |
| tgardner | apw, 2.6.39 ? | 17:43 |
| apw | no i seem to be running a 2.6.38-9 kernel | 17:43 |
| tgardner | it works in most cases. I think it still has issues with WPA2 enterprise. | 17:43 |
| tgardner | its still staging | 17:44 |
| apw | hmmm, ok, i'll let it play this week and see how/if it copes | 17:44 |
| jgould | apw, I've never found one, but I may not have the right terms | 17:45 |
| apw | i wonder when it switched over | 17:46 |
| apw | jgould, then do file one with ubuntu-bug | 17:46 |
| mfilipe | smb, I could compile the kernel with make-kpkg!!! :) | 17:47 |
| mfilipe | the commend was very big: make-kpkg --rootcmd=fakeroot --initrd --append-to-version=-i915patch --overlay-dir=/home/mfilipe/Workspace/linux-2.6.38-i915patch/linux-2.6.38 --revision=1 --jobs=4 kernel_image kernel_headers | 17:47 |

| hggdh | bjf: I just ran SRU tests against the karmix EC2 kernel; but the versions being reported are weird | 17:51 |
| bjf | hggdh, weird as in ? | 17:51 |
| hggdh | bjf: /proc/version_signature reports Ubuntu 2.6.31-308.28-ec2, but dpkg shows 2.6.31-308.29 | 17:52 |
| hggdh | sorry, slow typing | 17:52 |
| bjf | hggdh, not sure what to say about that | 17:55 |
| bjf | sconklin, thoughts? ^ | 17:55 |
| sconklin | reading | 17:56 |
| sconklin | strange, let me look at that branch of the repo | 17:56 |
| bjf | sconklin, looking at the .changes for the package i uploaded, it looks right to me | 18:00 |
| tgardner | bjf, the repo shows Ubuntu-2.6.31-308.29 | 18:03 |
| bjf | tgardner, yes | 18:03 |
| tgardner | bjf, this might be a CONFIG_VERSION_SIGNATURE issue | 18:04 |
| tgardner | hggdh, are you sure you booted the right kernel ? | 18:07 |
| hggdh | tgardner: sure? No. But please see http://pastebin.ubuntu.com/603352/ | 18:09 |
| * ppisati -> gym | 18:09 | |
| tgardner | hggdh, hmm, definitely bizarre. | 18:12 |
| hggdh | hum. Let me do a quick sanity check with smoser | 18:13 |
| hggdh | tgardner: some ec2 versions have peculiarities... | 18:15 |
| jgould | Bug has been filed | 18:15 |
| tgardner | hggdh, well, they shouldn't have version peculiarities. | 18:16 |
| tgardner | hggdh, I downloaded the package and groveled vmlinuz-2.6.31-308-ec2 for strings:Linux version 2.6.31-308-ec2 (buildd@crested) (gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9) ) #29-Ubuntu SMP Fri Mar 18 22:02:21 UTC 2011 (Ubuntu 2.6.31-308.29-ec2) | 18:18 |
| bjf | tgardner, i did some comparison between what is in our ppa and what is in the pocket, and they match | 18:21 |
| hggdh | so I really need to check with smoser | 18:21 |
| tgardner | hggdh, yep. good catch on the version though. | 18:21 |
| hggdh | tgardner: the peculiarities come in play on how one boots the original instance... | 18:21 |
| bjf | hggdh, something seems wonky on your end | 18:21 |
| hggdh | indeed | 18:22 |
| jgould | Ok. Back to the MacOS on this other machine for a while... | 18:32 |
| JFo | <-grabbing food... back soon | 18:37 |
| * tgardner --> lunch | 18:54 | |
| * jjohansen -> lunch | 20:16 | |
| === tgardner is now known as tgardner-afk | ||
| smoser | hggdh, i would assume that the kernel is reporting itself wrong in that case. | 20:58 |
| tgardner-afk | smoser, its can't be. that string is only stored in one place. I think the wrong kernel got installed. | 21:00 |
| smoser | tgardner-afk, hggdh so, i suspect that what happened here is that hggdh booted a karmic instance and apt-get upgrade (or perhaps apt-get dist-upgrade) | 21:02 |
| smoser | the result is that the kernel in dpkg was upgraded, but karmic will forever boot the kernel that it booted with | 21:02 |
| tgardner-afk | smoser, that seems likely | 21:05 |
| === smb` is now known as smb | ||
| smb | hggdh, smoser Be careful when looking at versions as it is sometimes easy to catch the version of the meta-package instead of the binary | 21:42 |
| * smb -> off for real | 21:47 | |
| hggdh | smb indeed, will keep it in mind | 21:48 |
