[00:00] there must be something i am mising. everything is set up as per the tutorials i read, but still the last kernel message that ends up on the serial console is: [00:00] [ 27.571317] EXT4-fs (dm-2): mounted filesystem without journal. Opts: (null) [00:01] then follows silence until i reboot, which is again indicated on the console: [ 1762.680197] Restarting system. [00:03] Specialist: are you sure there are actually kernel messages to be printed? [00:03] yes, i can see them using dmesg [00:03] Perhaps the console level for kernel messages is set to mask them being sent to the console? [00:03] Is "quiet" on the kernel command line? [00:04] BenC: no, quiet is not on the command line [00:04] Check printk level for console output then [00:05] Read and edit /etc/sysctl.d/10-console-messages.conf [00:13] BenC: it's 4 4 1 7 - what would i need to specify if i wanted to see all messages (googling did not help to figure this out - most hits just list the defaults) [00:14] Specialist: http://www.makelinux.net/ldd3/chp-4-sect-2.shtml [00:14] Section 4.2.2 and the line above it where you "echo 8 > ..." [00:15] Specialist: So changing the values to 8 should do it [00:15] thanks! [00:15] * BenC found that with google [00:16] BenC: just out of curiosity: what were your search terms? [00:16] linux kernel printk console level === yofel_ is now known as yofel [01:32] skaet: alpha3 to beta1 blurb added for the kernel section in the TechnicalOverview wiki, will add the more substantial Maverick to Natty blub in a bit. [01:32] ogasawara, awesome. thanks! [01:42] Howdy hi. Encryption question: How do I tell if pcrypt is actually being used? I don't seem to see it in ps, and the module use count is 0. === _LibertyZero is now known as LibertyZero [07:40] hi morning [07:42] hi, is it a problem if i got a compiled kernel with -dirty behind it's name? I already did make clean but no luck, still it adds -dirty. [07:42] it just means you changed it [07:44] ohsix: what do you mean by changed? afaik, if you do make clean, the dirty will go away [07:55] fairuz: do you have uncommitted changes? That can cause the dirty tag to be applied [07:55] jjohansen: of course! why i dont think of that before [07:57] jjohansen: what is the command to reset again (i tend to forget everything). something like git reset --hard master? [07:57] fairuz: to reset the head git reset --hard origin/master (if on the master branch) [07:57] fairuz: git checkout -f will throw away uncommitted changes [07:58] jjohansen: cool, ty [08:15] jjohansen: still bug hunting? [08:15] fairuz: not at the moment, but I do have several queued up [08:17] jjohansen: i suppose it's very time consuming? Seen that you and DrDetroit did test a lot of kernels [08:17] fairuz: yeah it can be, it just depends on the bug [08:19] hehe i should turn off my sound when I am napping [08:19] or mark myself away i guess === smb` is now known as smb [08:32] DrDetroit: oh sorry :D [08:33] fairuz: don't worry about it, you did nothing to apologize for === Guest94281 is now known as niko === DrDetroit is now known as DrD_away === lool- is now known as lool === doko_ is now known as doko [11:30] rebooting [12:25] how long does it take to move from master-next to master? [14:10] hi there, my struggle to figure out what is breaking s2ram for my machine on 2.6.38 continues. i got a serial console working. unfortunately, during suspend the serial console output changes to garbage (with no_console_suspend enabled) rather early during the suspend phase so that i cannot read the most interesting information. is this to be expected? [14:22] Specialist: it can happen, some further ideas might be found at [14:22] https://wiki.ubuntu.com/DebuggingKernelSuspend [14:22] https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume [14:26] jjohansen: thanks! i have to say that i have read those documents already a couple of times ;-) the only untested hypothesis that remains is the possibility of a kernel panic during suspend. i guess a usb keyboard will not indicate that event by flashing the keyboard led as usb will probably already be down, right? [14:27] Specialist: ugh, yeah usb keyboard making the flashing led trick less than useful [14:27] or less useful [14:28] well, then it's time to resurrect my ps/2 keyboard ;-) === chuck_ is now known as zul [14:49] yesterday someone also mentioned storing debug information in the cmos using the rtc. instead of using the current time (causing the information to decay) wouldn't it make sense to set a (disabled) alarm with the intended payload instead? that data should not decay... [14:50] Specialist: theres actually in practice lots of places to store that information, but the rtc is the lowest common denominator [14:51] ohsix: are you aware of any code sample that i may re-use? [14:55] Specialist: don't know what you're doing, i just saw the rtc comment and something about debugging suspend [14:57] ohsix: i am trying to figure out why my system sporadically freezes during s2ram. i alreadt tried serial console, but that becomes corrupted during suspend. so i thought that i'd modify the rtc state using a bitmask to record certain checkpoint information during the suspend phase [14:59] ppisati: thanks for verifying your bug! [15:00] Specialist: i used netconsole [15:02] ohsix: the thing is that for me the suspend fails so low-level that the rtc may be the only device that will still work reliably at that time [15:02] Specialist, I think the kernel uses the upper bits only and you have a few minutes only to read the information out of the rtc when you boot up again [15:04] ohsix: well, that's ok for me. i just spotted the implementation in drivers/base/power/trace.c, which seems like a good starting point for my debug code [15:12] Hi, when compiling a external module, can I specify the output folder for *.ko file? I use this right now to compile : make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C $(KERNEL_SRC) M=$(PWD) modules [15:16] fairuz: O= [15:16] but its not just the output folder for the .ko its all object files [15:18] fairuz, have you tried using using MOD_INSTALL_PATH with make modules_install ? [15:19] e.g. 'MOD_INSTALL_PATH=/foo make modules_install' [15:19] sforshee: I'm compiling __a__ module [15:19] an external one [15:20] fairuz, yes, but what does it do if you run that from your module's source dir? I don't know, but might be worth trying [15:21] sforshee: it will install the modules from the source tree not my module :D [15:21] jjohansen: already tried that before but no luck [15:22] fairuz, that's too bad [15:22] fairuz: hrmm, it should work I know I have used it with external modules, mind you that was years ago [15:26] * ogasawara back in 20min [15:28] jjohansen: that's why..i wonder myself whhy it didn't work. === sconklin is now known as sconklin-afk [15:31] fairuz, I just tried it and it did work [15:31] sforshee: what did you try? [15:32] make -C /path/to/kernel M=$(pwd) INSTALL_MOD_PATH=/path/to/modules modules_install [15:32] fairuz, that installed my module to /path/to/modules [15:33] sforshee: it will install just the external module? and not the other kernel modules? [15:33] fairuz, yes [15:34] fairuz, note that if you use a relative path it will be relative to the kernel source directory, not your module source dir [15:36] sforshee: it will just move the files or it will compile and move the files [15:37] fairuz: it should set the compiler to write the files to the target location [15:37] * jjohansen has used it in the past for source trees that were read only [15:40] I use this -> make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -C /home/x0152532/kernel-src M=/home/x0152532/remote-x0152532/tools/caches/pl310 INSTALL_MOD_PATH=/home/x0152532/remote-x0152532/tools/caches/pl310/bin modules_install [15:40] jjohansen, fairuz, just using the modules_install target didn't build for me, I had to do the modules target as well [15:40] and it installs lib/modules directory in my target folder [15:40] and no sign of my own modules [15:41] fairuz, see my comment above, you'll have to do a 'make modules' first [15:41] in my testing anyway [15:41] and that will build to your local directory [15:41] unless you use O=... [15:41] sforshee: done that [15:43] fairuz, don't know what to say, it installs my module [15:43] sforshee: in your case, it did not install /lib/modules/kernel-name in your target folder? [15:44] fairuz, no, it does create lib/modules/..., and installs the module there [15:44] sforshee: ah ok i got what you mean [15:44] fairuz, if you want something different I guess you could make a custom target in your local makefile [15:45] sforshee: it puts the module in /lib/modules/kernel-name/extra/* [15:45] fairuz, yes [15:46] sforshee: hmm not really what i want actually.. [15:46] I'm searching something like target-folder/mymodule.ko [15:47] fairuz, that may be the only thing the kernel makefile provides [15:47] ## [15:47] ## Ubuntu Kernel Team Meeting - Today @ 17:00 UTC - #ubuntu-meeting [15:47] ## agenda: https://wiki.ubuntu.com/KernelTeam/Meeting [15:47] sforshee: there's O= too but unfortunately, it didn't work for me..will dig it out later [15:48] sforshee: jjohansen: btw, thanks for helping [15:48] fairuz, iirc O= puts all the build targets in that dir, which probably isn't what you want anyway [15:48] fairuz, np [15:49] sforshee: that's ok for be. As long as the source folder is clean :) [15:49] *me [15:56] jjohansen: if we make a package, it will create headers, image, and src package automatically ? [15:56] or there is some work to do by hand === sconklin-afk is now known as sconklin [16:02] fairuz: make a package how? [16:02] *.deb files [16:03] jjohansen: something like this https://launchpad.net/ubuntu/+source/linux-ti-omap4/2.6.38-1204.5/+buildjob/2313441 [16:03] fairuz: hrmm, I'm sure what you are doing to build, a package can create each of those === jjohansen is now known as jj-afk [16:04] * jj-afk steps away for 20 [16:04] jjohansen: (i'm not really want to create packages, but just to fill my curiousity =)) === diwic is now known as diwic_afk [16:17] ogasawara, do you remember if bug #630748 was on skaet's radar last week?

[16:19] tgardner, for the eeepc-wmi backports, is it best to base the branch for the pull request off of master-next ? [16:19] sforshee, that works, but its not critical. [16:20] tgardner, yeah, there probably aren't any differences between master and master-next for that file, I was just wondering [16:21] thanks [16:21] sforshee, the advantage of using master is that it gives you a stable merge point, whereas master-next often gets rebased. however, small pull requests aren't that hard to figure out.

[18:56] ogasawara, the April 14 freeze date, is that when you'll upload or the last day we put changes into the repo ? [18:57] bjf: ideally, we'll make no changes to the kernel past that date, which means we'd have to upload ~2days prior for the builds to finish by the 14th [18:57] bjf: we can still apply changes, they'll just be subject to SRU [18:57] bjf: but there's no guarantee that those changes will warrant another upload [18:58] ogasawara, right, i'm just thinking that one way of thinking is that the code is actually frozen on the 12th [18:58] bjf: yep === tgardner-lunch is now known as tgardner [19:33] headset died [19:45] thanks pgraner :) [19:47] <-need food [20:49] * jjohansen -> lunch [21:16] kees, sconklin, I think we're OK to release Hardy.
