**** BEGIN LOGGING AT Tue Dec 21 02:59:59 2010 Dec 21 03:00:33 rsalveti: ping Dec 21 08:34:27 hi Dec 21 08:45:06 yo Dec 21 09:14:01 rsalveti, ok will post the script I'm using, I will first try to reduce the needed dependencies Dec 21 09:14:33 rsalveti, cooloney what are the instructions to install the new kernel? Dec 21 09:15:26 guerby: i normally, built the kernel package and dpkg -x linux-image.deb to get vmlinuz Dec 21 09:15:50 cooloney, do you have the .deb somewhere on the web? Dec 21 09:15:55 and use mkimage to generate uImage, then copy it over to the SD card boot partition Dec 21 09:16:15 guerby: oh, 1 second Dec 21 09:18:14 guerby: https://edge.launchpad.net/ubuntu/+archive/primary/+files/linux-image-2.6.35-1101-omap4_2.6.35-1101.3_armel.deb Dec 21 09:18:31 guerby: https://edge.launchpad.net/ubuntu/+source/linux-ti-omap4 Dec 21 09:18:44 this is the home page of the omap4 kernel in Ubuntu Dec 21 09:20:02 cooloney, thx downloading. dpkg -x... Dec 21 09:20:14 guerby: great, man Dec 21 09:20:59 guerby: i am trying to disable the USBLAN driver in the kernel, since i saw too many allocation issue in you reports Dec 21 09:21:12 guerby: and building kernel package in SD card directly not NFS Dec 21 09:21:28 cooloney, I have my data over NFS Dec 21 09:21:49 guerby: yeah, I know that Dec 21 09:23:57 cp vmlinuz-2.6.35-1101-omap4 /boot Dec 21 09:24:44 ln -s vmlinuz-2.6.35-1101-omap4 vmlinuz Dec 21 09:25:19 cooloney, no man for mkimage, what should I launch? Dec 21 09:25:58 guerby: oh, that doesn't work, need to use mkimage Dec 21 09:26:10 guerby: are you using ubuntu on host? Dec 21 09:26:24 cooloney, yes I'm running all on the pandaboard Dec 21 09:26:37 so running ubuntu Dec 21 09:26:44 just apt-get install uboot-mkimage Dec 21 09:26:55 it will give you mkimage Dec 21 09:27:24 guerby: try it and let me know the result. i have to be away for a while Dec 21 09:27:30 apt-get update Dec 21 09:27:31 cooloney, ok Dec 21 09:27:50 mkimage without arg? Dec 21 09:32:21 cannot find anything through google on how to run mkimage Dec 21 09:32:29 I'm just relaunching my builds Dec 21 09:38:03 guerby: mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Ubuntu Kernel" -d uImage Dec 21 09:38:21 with beeing your vmlinuz Dec 21 09:40:13 sebjan, thx, I've now a uImage file. Wonder what the next step is :) Dec 21 09:41:12 guerby: :) this one goes on your boot partition and will be loaded by u-boot on next reboot Dec 21 09:41:14 plenty of files still pointing to the old version in /boot (I just changed the vmlinuz symlink) Dec 21 09:42:07 sebjan, mount /dev/mmcblk0p1 /tmp/mnt Dec 21 09:42:10 guerby: well, if you want ot make things the 'clean' way, you have to install a new kernel package, which will install the kernel modules, generate and install the new uImage to the boot partition Dec 21 09:42:29 guerby: to be quicker, you can grab the vmlinuz -> ui Dec 21 09:42:32 sebjan, cooloney pointed me to https://edge.launchpad.net/ubuntu/+archive/primary/+files/linux-image-2.6.35-1101-omap4_2.6.35-1101.3_armel.deb Dec 21 09:42:39 sebjan, then asked me to dpkg -x etc... Dec 21 09:42:46 sebjan, should I just dpkg -i ? Dec 21 09:43:05 guerby: right: generating the uImage and coying it to the boot partition Dec 21 09:43:31 guerby: hum, if you wan to be able to use the kernel modules, yes, you would have to dpkg -i Dec 21 09:44:02 sebjan, so all the dpkg -x and mkimage is not needed? Dec 21 09:44:10 (and manual symlink) Dec 21 09:44:50 guerby: right. dpkg -i shall do it all Dec 21 09:45:40 the dpkg -x avoids you to install a new kernel package. So it is a good option for a single test and avoid to 'polute' your file-system with a new kernel package Dec 21 09:46:02 guerby: since you already have you uImage file, you can just give it a try Dec 21 09:46:21 sebjan, what about old initrd & all in /boot ? Dec 21 09:46:40 I don't have a new uInitrd either for the boot partition Dec 21 09:48:18 guerby: this should not hurt too much (unless you have an encrypted root-fs?). You shall be able to boot, but you will be missing the kernel modules anyway. Dec 21 09:48:58 guerby: and yes, to mount the boot partition: mount /dev/mmcblk0p1 /tmp/mnt Dec 21 10:05:10 sebjan, no kernel module means that I won't be able to do anything right? Dec 21 10:05:26 no NFS, no openvpn etc... Dec 21 10:08:23 guerby: it will depend if your use-case needs additional kernel modules... For example, you will have ethernet support, so NFS mount may be working. Dec 21 10:08:57 guerby: do you have an easy access to your board, and a way to update the SD card content easily (using your host PC for example?) Dec 21 10:09:37 sebjan, yes I can put the SD on my PC if needed Dec 21 10:09:40 guerby: if yes, then it's worth gibing a try. If it fails you'll be able to recover easily by just recopying the original uImage instead of your test one Dec 21 10:09:57 (just keep a copy of your current uImage) Dec 21 10:10:28 sebjan, I think I'll just wait for a new image in apt-get upgrade Dec 21 10:10:59 guerby: that's another (easier) option :) Dec 21 10:11:07 sebjan, lots of commands to run means lots of potential mistakes and lots of time to recover Dec 21 10:11:29 guerby: sorry I missed the beginning of the thread. why do you want to upgrade your kernel? Dec 21 10:11:34 guerby: (right :)) Dec 21 10:12:31 sebjan, because the current kernel crashes (board freezed, no LED, no ping) without message anywhere including serial Dec 21 10:12:42 sebjan, when I'm just compiling GCC on a NFS mount Dec 21 10:12:57 sebjan, https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/690370 Dec 21 10:12:59 Launchpad bug 690370 in linux-ti-omap4 (Ubuntu) "Strange out of memory on pandaboard (affects: 1) (heat: 10)" [Undecided,New] Dec 21 10:13:20 guerby: ok, and you wanted to try alternative kernels (like the Natty one), right? Dec 21 10:13:27 sebjan, I also have plenty of messages in /var/log/messages when swap is activated. When swap is inactive user level process get failing malloc Dec 21 10:13:33 sebjan, yes anything :) Dec 21 10:19:37 (failing malloc while there are many 100MB free/cached) Dec 21 11:55:53 can someone take a look at bug 688010? Dec 21 11:55:55 Launchpad bug 688010 in ubuntu-netbook-default-settings (Ubuntu) "Missing dependency on gconf2 (affects: 1) (heat: 8)" [Undecided,New] https://launchpad.net/bugs/688010 Dec 21 12:06:57 morning Dec 21 12:08:28 guerby: you can wait and try natty's image Dec 21 12:08:46 we just need to get the u-boot changes fixed then our daily images will be generated again Dec 21 12:09:09 rsalveti, ok will wait :) I'm currently testing bootstrap with C only to reduce the requirements Dec 21 12:09:25 ok :-) Dec 21 15:00:58 guerby: i see you're having fun :) Dec 21 15:01:16 armin76, yeah I'm always lucky with new hw Dec 21 15:01:31 armin76, I guess I should do web browsing instead of compiling stuff ... :) Dec 21 15:02:12 armin76, kernel diagnostic seems to be still in jurassik state ... Dec 21 19:45:12 Hey everyone I just want to thank you all for the wonderful OS on behalf of me and the people of france and the crew at http://www.myefact.com we wouldnt have been able to do half of what we do if it wasn't for Ubuntu so THANKS UBUNTU DEVS!! Dec 21 21:01:47 hi everyone... Dec 21 21:02:18 coming back... where are the latest builds for the igep OMAP / A8 **** ENDING LOGGING AT Wed Dec 22 02:59:57 2010
