**** BEGIN LOGGING AT Sun Jul 01 02:59:59 2012 Jul 01 08:47:35 hmm, leap second desaster Jul 01 08:48:25 yup, none of my boxes affected this time though Jul 01 08:48:54 last time it took out one of my boxes. it just hung. Jul 01 09:15:39 looks like java and mysql-instances got hit Jul 01 09:15:48 yup Jul 01 09:16:10 besides a bug in the kernel Jul 01 09:16:25 fascinating that just setting the date is enough to fix those Jul 01 09:16:48 I think that's the old kernel bug that hit that leapsecond years ago too. Jul 01 09:18:55 no, it git fixed in 3.4 Jul 01 09:19:00 6b43ae8a619d17c4935c3320d2ef9e92bdeed05d Jul 01 09:19:30 s/3.4/3.3/ Jul 01 09:19:57 s/git/got/ Jul 01 09:20:13 the git-god Jul 01 09:20:14 ;) Jul 01 09:22:36 hmpf, to early in the morning, it was fixed in 3.4 and not 3.3 ;) Jul 01 09:32:30 and it doesn't seem to have reached the stable-series Jul 01 09:35:06 and beagleboard.org is still down ;) Jul 01 09:40:50 but I assume some people in the US have other problems than only halted servers. Must been a violent weather there Jul 01 17:41:23 Hi all ! i regulary get kernel panic on my Beagleboard Xm REV C4....anyone can help me identify where the problem is ? Jul 01 17:45:54 Hi all ! i regulary get kernel panic on my Beagleboard Xm REV C4....anyone can help me identify where the problem is ? Jul 01 17:46:26 I bet there are quite many people who could. if you wouldn't repeat yourself and instead provide a URL to such a panic (hint: pastebin) Jul 01 17:50:08 Here the link to the oops exception : http://pastebin.com/download.php?i=KULSFGGd Jul 01 17:55:57 no one wants todownloadthat stuff, so it is http://pastebin.com/KULSFGGd Jul 01 17:56:19 hmpf, space key dirty again ;) Jul 01 17:57:12 ok ...sorry Jul 01 17:59:05 what a kernel is that? Jul 01 17:59:31 3.2.21-x13 Jul 01 17:59:41 what is x13? Jul 01 18:01:13 STABLE http://rcn-ee.net/deb/squeeze-armel/v3.2.21-x13/ Jul 01 18:02:57 i don't really know what x13 means... Jul 01 18:03:30 It is a build number. Jul 01 18:03:51 Just like the 5 in 2.6.32-5 Jul 01 18:04:25 but it no we know that it is a kernel from rcn build for debian/ubuntu. That was the question Jul 01 18:05:40 And the x probably designates it as an experiemntal kernel. Jul 01 18:05:51 Or a differing branch from mainline, at least. Jul 01 18:06:06 no, it is mentioned as "stable" Jul 01 18:06:15 you might try the plain mainline kernel, 3.2.21 works here without problems Jul 01 18:06:23 cat /etc/issue : Debian GNU/Linux 6.0 Jul 01 18:08:36 I can't find 3.2.21 from http://rcn-ee.net/deb/ ... Jul 01 18:09:28 but mayne http://rcn-ee.net/deb/ is not the main and official repository for Beagle ....? Jul 01 18:09:39 but maybe http://rcn-ee.net/deb/ is not the main and official repository for Beagle ....? Jul 01 18:09:45 You said that. Jul 01 18:10:08 Also, I am not sure there is an *official* repo for the Beagleboard. Jul 01 18:10:16 there was an error : mayne=maybe Jul 01 18:10:17 Especially not for Debian. Jul 01 18:10:26 No need to repeat the whole line, though. Jul 01 18:10:42 Most of us on IRC are good at ignoring the occasional error. ;-P Jul 01 18:10:58 ok sorry agmlego...i'm new in there Jul 01 18:11:09 And if you really feel it necessary to correct, the accepted method is to prepend a * character before the single word to correct. Jul 01 18:11:16 Guest83483: Not a problem. Jul 01 18:12:03 Guest83483: do you know how to compile a kernel? Jul 01 18:12:25 Looks like the x13 designates a patch set. Jul 01 18:13:58 i don't know how to compile a kernel, but Googling it will tell me how to, i guess. Basically, i've followed instructions here to install my system : http://elinux.org/BeagleBoardDebian Jul 01 18:15:48 here is the config for 3.2.21 I'm using on my C4: http://ahsoftware.de/config-3.2.21.beagleboardC4 you might git clone the stable 3.2.21 from kernel.org and compile it yourself Jul 01 18:16:21 Or, you know, just roll back the kernel in apt? Jul 01 18:18:59 and using ubuntu on a c4 isn't very stable. I think ubuntu uses thumb and the c4 has a problem with that Jul 01 18:20:03 s/c4/omap 3 on the c4/ Jul 01 18:20:22 I would like to use Debian, not Ubuntu... Jul 01 18:21:37 Here is the apt-cache search linux-image output i have : http://pastebin.com/cSEDnupH Jul 01 18:21:41 I don't know if debian uses thumb too. but it shouldn't be necessary to use rcn's kernel with patches you don't know anything about Jul 01 18:26:17 using apt to downgrade my kernel, do you think "linux-image-2.6.32-5-versatile" is a good choice ? Jul 01 18:26:55 Might be a good place to start. Jul 01 18:27:21 However, I would be surpised (very surprised) if the mirror you are using does not have an older 3.2 kernel you could try first. Jul 01 18:27:31 And, if your mirror does not have such, get a new mirror. Jul 01 18:27:47 Going all the way back to a 2.6 kernel is a hell of a long downgrade. Jul 01 18:28:34 Maybe i should do it on a new sdcard...? Jul 01 18:28:48 Oh, assuredly, or back up the one you have. Jul 01 18:29:14 ok, i do an sdcard image backup right now Jul 01 18:29:26 I would just use dd to make an image of the card and save it on a different machine, then make changes. Jul 01 19:08:22 I ran apt-get install linux-image-2.6.32-5-versatile but after reboot the board is still using 3.2.21-x13 ... Jul 01 19:24:37 Well, yeah, because you did not tell the board to boot up on that kernel. Jul 01 19:27:27 How can i do that ? Jul 01 19:28:22 No idea. What does Googlesay? Jul 01 19:28:33 On regular PCs, you use GRUB or LILO or other bootloader. Jul 01 19:28:42 My guess it it will be something in uboot. Jul 01 20:58:04 everything rhat Google tell me fail... Jul 01 20:58:41 rhat=that Jul 01 20:59:00 look at the serial, it should tell you which file gets loaded Jul 01 21:00:32 and check u-boot-version etc. the c4 has nand and the u-boot in nand might be very old Jul 01 21:08:44 what gstreamer encoders are best on the bone? Jul 01 21:08:45 I boot from sdcard, not from Nand Jul 01 21:08:51 is there a dsp powered encoder? Jul 01 21:13:22 looks like the beagleboard has mpeg-4 hardware encoding support. is this also true for the bone? Jul 01 21:13:41 no dsp on the bone Jul 01 21:13:57 :( Jul 01 21:26:44 well...maybe i made a mistake with the beagle, i need someting stable for my project....for the price of the Beagle, not sure i can expect something stable...i will maybe have a look here http://www.embeddedarm.com/products/arm-sbc.php Jul 01 21:28:40 Guest83483: What instability are you seeing? Jul 01 21:28:53 kernel panics ! Jul 01 21:29:10 with no specific dev at all Jul 01 21:29:43 going embedded without being able to compile a kernel isn't the right way. Jul 01 21:30:56 Guest83483: what distros have you tried? Jul 01 21:31:04 Angstrom works very nicely, as does Ubuntu. Jul 01 21:32:36 you're right aholler, i am learning. I am refering to the community that makes great jobs to make Debian and all others dist Beagle compliant Jul 01 21:32:59 Angstrom will probably give you better performance, while Ubuntu will give you a user experience similar to Debian. Jul 01 21:33:24 i've tried Angstrom but this dist is very minimal and i can't do what i want : for instance just installing Apache2 Jul 01 21:33:50 Perhaps you need to rethink embedded. Jul 01 21:34:32 no, i don't have to rethink (this would be the easiest way)...i have to learn more and more Jul 01 21:35:20 Guest83483: Try the server edition of Ubuntu. Jul 01 21:35:51 Or, try compiling apache. Jul 01 21:35:51 There are lighter alternatives to Apache that may serve you better. Jul 01 21:36:10 nginx is a good one, as is lighttpd. Jul 01 21:36:41 Assuming, of course, the goal is simply a webserver. If you have apache-specific things, those may not be the right solution. Jul 01 21:37:06 busybox already has one included Jul 01 21:37:26 with php support ? gd support ? rrdtools ? the easiest way for all that is "standard" dist as Debian/Ubuntu (in my opinion) Jul 01 21:37:51 PHP? Yes. GD? What is that? RRDtools? Maybe. Jul 01 21:38:20 Perhaps "easiest" for you but also probably not well suited to embedded. Perhaps you need to rethink. Jul 01 21:39:02 If i have to rethink, i will have a look to embedded x86 boards Jul 01 21:39:03 apache and embedded in the same sentence... Jul 01 21:39:26 not with Angstom dm8tbr... ;) Jul 01 21:39:37 Guest83483: wooooosh... Jul 01 21:39:51 Guest83483: What dm8tbr is saying is that Apache is a grossly bloated webserver to run on an embedded board. Jul 01 21:40:13 using apache isn't really a problem. Jul 01 21:40:15 (Really, it is grossly bloated to run on anything, but that is a topic for a different discussion.) Jul 01 21:40:43 There is a reason Apache isn't included in embedded distributions. Jul 01 21:40:51 That is it. Jul 01 21:41:23 you /can/ do a great many things. if you /should/ is on a different page. Jul 01 21:41:38 Guest83483: The big question I have is: What are you wanting to do? Jul 01 21:41:43 because there normally is no need for it. but that doesn't say anything if it isn't possible Jul 01 21:42:00 I'm using apache since 3a on a armv5 with 128mb Jul 01 21:42:09 without problems Jul 01 21:42:31 I am sure of that aholler...with a stable Kernel ! Jul 01 21:43:06 than get a stable one Jul 01 21:43:10 yada yada, there are enough people who run the BBxm and don't have kernel problems. Jul 01 21:44:12 Sure dm8tbr...but Google said that there is also a lot of people who get a "Unable to handle kernel paging request at virtual address xxxxxxx" Jul 01 21:44:18 Guest83483: you are just trying the first experimental kernel you've found somewhere and already start to whine because something doesn't work Jul 01 21:47:35 ok ok ! I've found the most active developper for the Beagle at http://rcn-ee.net ...maybe here is my main mistake Jul 01 21:47:58 your mistake is missing patience Jul 01 21:48:12 lol ! no ! :) Jul 01 21:48:26 rcn-ee is sometimes here. so just wait Jul 01 21:50:03 "What are you wanting to do?" this is a large question Jul 01 21:50:51 Basically, i want to manage devices to manage a room weather Jul 01 21:51:29 with a http server for GUI Jul 01 21:51:37 with php5 and GD Jul 01 21:52:35 GD is a library to draw over an image (for instance http://saratoga-weather.org/scripts-widget.php) Jul 01 21:56:09 you can have a look in my dev app here : http://88.177.138.193/greenbox (guest / guest) Jul 01 21:59:52 So, in this case, you are simply going for a small webserver, then. Jul 01 21:59:56 I would try using Ubuntu. Jul 01 22:04:07 ok, after Angstrom and Debian, i will try Ubuntu Jul 01 22:09:09 To manage sensors and relays i use Phidgets boards conected on the Beagle usb port. So, i also have compiled C programs to retrieve datas. Actually the poller is the crontab Jul 01 22:10:25 In my app you can try start/stop fan : it will actually on/off a light bulb Jul 01 22:17:48 I am doing an image backup rollback to my sdcard because i've messed up my card while trying to downgrade my Kernel. I will install Ubuntu on a new sdcard Jul 01 22:28:27 I've tried this and i had no stability problems http://www.viaembedded.com/en/products/boards/730/1/EPIA-P710_%28EOL%29.html . I went to ARM because it is lowercost and faster at boot, and i love the fact that the HDD is an sdcard Jul 01 22:28:46 ;) Jul 01 22:33:31 Anyone here using Apache2 and compiled C programs with no kernel panics on Beagle Xm rev C4 ? please tell which Kernel and Distrib you are using ! :) Jul 01 22:34:44 I have been using Ubuntu Precise server edition on an xM C4 with no issues. Jul 01 22:35:37 kernel ? Jul 01 22:38:46 Latest in repos. Jul 01 22:39:02 Which repo ? I'm going to try this http://elinux.org/BeagleBoardUbuntu Jul 01 22:39:04 I do not have the device near me, so i cannot tell you more exactly. Jul 01 22:39:12 Yeah, that was what i followed. Jul 01 22:39:26 ok thanks man Jul 01 22:41:02 Ubuntu is not my favorite dist, Debian is, but no matters i will try it to see if i still get Kernel Panic issues Jul 01 22:42:14 Is there a compelling reason to favour one over the other? Jul 01 22:43:34 i don't like to be an assisted person : don't want to "sudo" everything !! :) Jul 01 22:44:19 (bad resaon) it's mine ! Debian is right on the way Jul 01 22:44:36 So use Ubuntu as root. Totally possible. Jul 01 22:44:49 But yeah, that is a bad reason. Jul 01 22:44:50 i guess it is, i will do Jul 01 22:45:15 just give root a password, done. Jul 01 22:45:28 it's that easy Jul 01 22:46:12 Ubuntu is based on Debian....Why ? because Debian is the most easy, compliant, reliable, versatile dist ever ! Jul 01 22:46:12 Exactly. Jul 01 22:47:04 Ubuntu is based on Debian because people wanted something with a faster update cycle, less cumbersome licencing restrictions, and a more user-friendly interface than Debian. Jul 01 22:47:16 Much the same reason Fedora exists, based on RHEL. Jul 01 22:47:35 fedora is testbed for rhel Jul 01 22:48:03 As was Ubuntu for Debian. Jul 01 22:48:09 To me, Redhat is bulls***t Jul 01 22:48:18 Noite the *was*, Ubuntu is no longer fully linked to Debian. Jul 01 22:48:37 I wouldn't compare the ideas behind fedora/rhel and debian/ubuntu Jul 01 22:48:46 they are too different Jul 01 22:48:47 me no either Jul 01 22:49:00 u right Jul 01 22:49:15 aholler: As a former mirror operator for the four (and others), there are enough similarties that the analogy works. Jul 01 22:49:41 yes, they all offer mirrors Jul 01 22:49:53 aholler: Har. Jul 01 22:50:12 mirror, mirror on the net... Jul 01 22:51:14 Guest83483: btw. suse exists for arm too, you can try fedora and suse too. Jul 01 22:51:40 And I heard good things about Arch and Gentoo too. Jul 01 22:52:11 whatever, I'm sure there working debians out too. Jul 01 22:52:23 Possibly. Jul 01 22:52:25 Sure i could try...but my goal is to use Debian !! Jul 01 22:52:38 I had a rough time with Debian too when I tired it, and that is my native distro too. Jul 01 22:52:39 maybe ask debian people Jul 01 22:53:43 That's why i am here ! i'm sure there is Debian people in here :) Jul 01 22:53:48 if it is the most easy, compliant, reliable and versatile dist ever, there should be someone there which knows how to use that on the beagle Jul 01 22:54:02 hope! Jul 01 22:54:09 and I'm sure they have their own channel Jul 01 22:54:23 and ml and whatever Jul 01 22:54:23 Guest83483: #debian on freenode might be useful. Jul 01 22:54:30 Or #armhf Jul 01 22:54:51 Er, #armel. Jul 01 22:55:12 people here are more hardcore than the usual debian people Jul 01 22:55:20 Not sure either of those exist anymore. Jul 01 22:55:28 whouhou thanks ! i don't know all IRC channels Jul 01 22:55:59 just ask the website from your favorite distribution; debian.org Jul 01 22:56:25 why http://www.embeddedarm.com/products/arm-sbc.php uses Debian OS ? because it is...the best :) Jul 01 22:56:27 Guest83483: I doubt anyone does. Jul 01 22:56:39 Know all the IRC channels, that is. Jul 01 22:58:36 fanbis are thinking apple is the best Jul 01 22:59:10 and for xda-people there exists only one rom Jul 01 22:59:36 and emacs is a os Jul 01 23:00:34 and java is fast, error free and runs everywhere… Jul 01 23:02:03 besides that world is flat ;) Jul 01 23:02:05 Java is heavy, Apple is closed, emacs is for notepad users (vi the best) Jul 01 23:03:47 and Java is not so cross platform as they say ! Jul 01 23:11:06 reloading my sdcard makes my serial port not working anymore Jul 01 23:13:54 it was a usb to serial driver error : solved Jul 01 23:14:50 aholler : can you try to start/stop my fan (in fact my light bulb) for test ? Jul 01 23:17:46 admin / admin Jul 01 23:21:35 (or anyone can try) Jul 01 23:29:33 well...i understand that you might not be interested in that test, nevermind.... Jul 01 23:30:04 Guest83483: I do not recall seeing a URI for your device, so... Jul 01 23:32:04 agmlego: i don't understand what u mean... Jul 01 23:32:43 Guest83483: How are we to try your system, if we do not know where your system is? Jul 01 23:33:05 You need to provide the URI where your device is located for us to use the username and password you provided. Jul 01 23:33:47 ha ok, i told it before : it is http://88.177.138.193/greenbox (admin / admin Jul 01 23:34:02 ) Jul 01 23:35:04 As I said, I did not remember seeing that link. Jul 01 23:35:16 no pb Jul 01 23:35:33 light is on ! Jul 01 23:36:06 Also, keep in mind that many/most IRC channels are logged in one way or another--assume that the connection details and credentials for that have been shared to the world. Jul 01 23:37:10 i have no pb for that ! Credentials have been changed for now bur i will put the "true" credantials once finished Jul 01 23:37:43 my app is not a secret and is open minded ! Jul 01 23:38:44 Well, it is usually a bad idea to keep the access for the controls on physical devices open and freely accessible. Jul 01 23:38:53 Look at the results of Stuxnet for instance... Jul 01 23:39:46 I know, i don't worry. If you want to go further, i can put my light sensor closer to the light bulb : so that you will the light curve growing Jul 01 23:40:10 Heh. Jul 01 23:40:14 No, that is OK. Jul 02 01:12:40 * mranostay pokes in Jul 02 02:49:45 looking for a wifi/bt module on BeagleXM **** ENDING LOGGING AT Mon Jul 02 02:59:58 2012
