[01:46] <rsalveti> guerby: no new ideas for now :-(
[01:46] <rsalveti> cooloney: maybe you can help us with this issue
[01:47] <rsalveti> guerby: is building gcc at his pandaboard
[01:47] <cooloney> rsalveti: oh, i missed your conversation here
[01:47] <cooloney> rsalveti: need i to help to building gcc?
[01:47] <rsalveti> and after a while the board just hang, without giving any extra message at the serial console
[01:47] <rsalveti> nothing
[01:47] <rsalveti> the heartbeat led stops working
[01:47] <rsalveti> so the kernel is dead
[01:47] <rsalveti> but no trace at the console
[01:48] <rsalveti> cooloney: now how can we debug this kind of issue?
[01:49] <rsalveti> maybe some more debugging around the kernel
[01:49] <cooloney> rsalveti: hmm, still have no clue. need a smalll testcase instead of building a whole kernel package
[01:50] <cooloney> rsalveti: highmem might not be a issue. I've tested the linaro kernel which disabled highmem
[01:50] <cooloney> rsalveti: and we still got that issue
[01:50] <rsalveti> cooloney: but this is not the one we're used to see
[01:50] <rsalveti> in this case the kernel is basically dead, without giving any other message at the console
[01:51] <rsalveti> cooloney: see bug 690370
[01:51] <ubot2> Launchpad bug 690370 in linux-ti-omap4 (Ubuntu) "Strange out of memory on pandaboard (affects: 1) (heat: 10)" [Undecided,New] https://launchpad.net/bugs/690370
[01:52] <cooloney> rsalveti: oh, my bad, i assume is the old issue
[01:52] <cooloney> rsalveti: thx, man, i will take a look
[01:53] <rsalveti> guerby: can you post tomorrow the instructions needed to run the build at the bug? then cooloney can help reproducing this issue with his board
[01:54] <rsalveti> cooloney: first issue is the page allocation failure when stressing the memory
[01:54] <rsalveti> this is probably caused by the usb driver
[01:54] <rsalveti> I believe it's requesting more memory that it should to work normally
[01:54] <rsalveti> then the other issue while building gcc is this weird hang
[01:54] <rsalveti> no message, no blinking led, nothing
[01:55] <rsalveti> guerby: there's also a new kernel if you want to try, that's the one currently used at natty
[01:55] <rsalveti> same tree but with some new features
[01:59] <cooloney> rsalveti: thx. i was told before building perl is also hang on panda
[02:00] <rsalveti> cooloney: weird, never saw this with my panda
[02:00] <rsalveti> we could try natty's kernel and the one based at 37
[02:01]  * rsalveti brb
[02:58] <TheUni> rsalveti: ping
[08:32] <hrw> hi
[08:43] <AceLan> yo
[09:12] <guerby> rsalveti, ok will post the script I'm using, I will first try to reduce the needed dependencies
[09:12] <guerby> rsalveti, cooloney what are the instructions to install the new kernel?
[09:13] <cooloney> guerby: i normally, built the kernel package and dpkg -x linux-image.deb to get vmlinuz
[09:14] <guerby> cooloney, do you have the .deb somewhere on the web?
[09:14] <cooloney> and use mkimage to generate uImage, then copy it over to the SD card boot partition
[09:14] <cooloney> guerby: oh, 1 second
[09:16] <cooloney> guerby: https://edge.launchpad.net/ubuntu/+archive/primary/+files/linux-image-2.6.35-1101-omap4_2.6.35-1101.3_armel.deb
[09:16] <cooloney> guerby: https://edge.launchpad.net/ubuntu/+source/linux-ti-omap4
[09:17] <cooloney> this is the home page of the omap4 kernel in Ubuntu
[09:18] <guerby> cooloney, thx downloading. dpkg -x...
[09:18] <cooloney> guerby: great, man
[09:19] <cooloney> guerby: i am trying to disable the USBLAN driver in the kernel, since i saw too many allocation issue in you reports
[09:19] <cooloney> guerby: and building kernel package in SD card directly not NFS
[09:19] <guerby> cooloney, I have my data over NFS
[09:20] <cooloney> guerby: yeah, I know that
[09:22] <guerby> cp vmlinuz-2.6.35-1101-omap4 /boot
[09:23] <guerby> ln -s vmlinuz-2.6.35-1101-omap4 vmlinuz
[09:23] <guerby> cooloney, no man for mkimage, what should I launch?
[09:24] <cooloney> guerby: oh, that doesn't work, need to use mkimage
[09:24] <cooloney> guerby: are you using ubuntu on host?
[09:24] <guerby> cooloney, yes I'm running all on the pandaboard
[09:24] <guerby> so running ubuntu
[09:25] <cooloney> just apt-get install uboot-mkimage
[09:25] <cooloney> it will give you mkimage
[09:25] <cooloney> guerby: try it and let me know the result. i have to be away for a while
[09:25] <guerby> apt-get update
[09:25] <guerby> cooloney, ok
[09:26] <guerby> mkimage without arg?
[09:30] <guerby> cannot find anything through google on how to run mkimage
[09:30] <guerby> I'm just relaunching my builds
[09:36] <sebjan> guerby: mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Ubuntu Kernel" -d <file> uImage
[09:36] <sebjan> with <file> beeing your vmlinuz
[09:38] <guerby> sebjan, thx, I've now a uImage file. Wonder what the next step is :)
[09:39] <sebjan> guerby: :) this one goes on your boot partition and will be loaded by u-boot on next reboot
[09:39] <guerby> plenty of files still pointing to the old version in /boot (I just changed the vmlinuz symlink)
[09:40] <guerby> sebjan, mount /dev/mmcblk0p1 /tmp/mnt
[09:40] <sebjan> 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
[09:40] <sebjan> guerby: to be quicker, you can grab the vmlinuz -> ui
[09:40] <guerby> 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
[09:40] <guerby> sebjan, then asked me to dpkg -x etc...
[09:41] <guerby> sebjan, should I just dpkg -i ?
[09:41] <sebjan> guerby: right: generating the uImage and coying it to the boot partition
[09:41] <sebjan> guerby: hum, if you wan to be able to use the kernel modules, yes, you would have to dpkg -i
[09:42] <guerby> sebjan, so all the dpkg -x and mkimage is not needed?
[09:42] <guerby> (and manual symlink)
[09:43] <sebjan> guerby: right. dpkg -i shall do it all
[09:43] <sebjan> 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
[09:44] <sebjan> guerby: since you already have you uImage file, you can just give it a try
[09:44] <guerby> sebjan, what about old initrd & all in /boot ?
[09:44] <guerby> I don't have a new uInitrd either for the boot partition
[09:46] <sebjan> 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.
[09:47] <sebjan> guerby: and yes, to mount the boot partition: mount /dev/mmcblk0p1 /tmp/mnt
[10:03] <guerby> sebjan, no kernel module means that I won't be able to do anything right?
[10:03] <guerby> no NFS, no openvpn etc...
[10:06] <sebjan> 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.
[10:07] <sebjan> 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?)
[10:07] <guerby> sebjan, yes I can put the SD on my PC if needed
[10:07] <sebjan> 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
[10:08] <sebjan> (just keep a copy of your current uImage)
[10:08] <guerby> sebjan, I think I'll just wait for a new image in apt-get upgrade
[10:09] <sebjan> guerby: that's another (easier) option :)
[10:09] <guerby> sebjan, lots of commands to run means lots of potential mistakes and lots of time to recover
[10:09] <sebjan> guerby: sorry I missed the beginning of the thread. why do you want to upgrade your kernel?
[10:09] <sebjan> guerby: (right :))
[10:10] <guerby> sebjan, because the current kernel crashes (board freezed, no LED, no ping) without message anywhere including serial
[10:10] <guerby> sebjan, when I'm just compiling GCC on a NFS mount

[10:11] <sebjan> guerby: ok, and you wanted to try alternative kernels (like the Natty one), right?
[10:11] <guerby> 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
[10:11] <guerby> sebjan, yes anything :)
[10:17] <guerby> (failing malloc while there are many 100MB free/cached)
[11:54] <hrw> can someone take a look at bug 688010?

[12:05] <rsalveti> morning
[12:06] <rsalveti> guerby: you can wait and try natty's image
[12:07] <rsalveti> we just need to get the u-boot changes fixed then our daily images will be generated again
[12:07] <guerby> rsalveti, ok will wait :) I'm currently testing bootstrap with C only to reduce the requirements
[12:07] <rsalveti> ok :-)
[14:59] <armin76> guerby: i see you're having fun :)
[14:59] <guerby> armin76, yeah I'm always lucky with new hw
[14:59] <guerby> armin76, I guess I should do web browsing instead of compiling stuff ... :)
[15:00] <guerby> armin76, kernel diagnostic seems to be still in jurassik state ...
[19:43] <efactusa> 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!!
[20:59] <rlameiro> hi everyone...
[21:00] <rlameiro> coming back... where are the latest builds for the igep OMAP / A8
