davmor2hey guys I have an issue on a HP G62.  When ever the webcam is activated it kills the system.  There are no flashing leds,  I've tried using ssh and tailing the syslog but as soon as the webcam activates the ssh stops sending and the system is in hard lock up, there isn't a sysrq button on the laptop either :(11:23
davmor2this however stops me installing via ubiquity as it triggers the webcam11:23
davmor2checking the logs currently11:23
davmor2paste.ubuntu.com/1171601/ is all I see in the syslog,  I mounted the cd to log where the I started the cheese application.11:30

ChogyDanhi guys, Im trying to write a specific guide for compiling a kernel.  Ive been following this page: https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel     and there are some errors12:59
rtgChogyDan, the 'Building the kernel' part should prolly use dpkg-buildpackage so that uninstalled build dependencies get caught13:01
ChogyDanrtg: oO     that wasn't even what I was talking about.  Do you know of a guide that is actually accurate?13:02
rtgChogyDan, on the surface of it, I think it looks accurate. maybe you could tell me what specific errors you're having ?13:03
ChogyDanthe part about configuration.  chmod a+x debian/scripts/misc/*     <---- that doesn't hit /debian/scripts/config-check13:04
ChogyDan(Im having trouble understanding the configuration stuff in general, which is why Im focusing on it)13:04
rtgChogyDan, looks like its  already executable, at least if you clone it using git.13:05
ChogyDanrtg: Im using apt-get13:05
rtglemme check...13:06
ChogyDanrtg: anyway, it is a minor error.  The main issue is after I apply a patch set Im working on, Im getting config errors.  I still need to work through that13:08
ChogyDanrtg: thanks for confirming the guide!13:09
rtgI'll add the one line so that all the files are marked executable13:09
ChogyDansounds good13:12

* ogra_ wonders what went wrong with rsalveti's patch to install linux/omap_drv.h14:19
ogra_i cant find it in either 3.5.0-12.12 nor 3.5.0-13.1314:19
ogra_(assuming its supposed to land in the linux-libc-dev binary package)14:20
rtgogra_, 'UBUNTU: [Config] installing omapdrm specific headers for external drivers' ?14:23
ogra_rtg, yeah14:23
ogra_that should install linux/omap_drv.h in linux-libc-dev:armhf 14:24
rtgshould be in Ubuntu-3.5.0-12.1214:24
ogra_but i somehow cant find where it actually ends up14:24
ogra_right, its neither in 12.12 nor in 13.1314:24
rtgogra_, its in the headers package 14:24
ogra_which one ?14:24
rtgogra_, in each flavour AFAICT14:25
ogra_if it goes into an arch specific headers package that doesnt help, we only install linux-libc-dev:armhf from that build on panda14:25
ogra_all other headers come from linux-ti-omap414:25
ogra_well, everything thats called linux-hearders-* at least14:26
ogra_aha14:27
ogra_ubuntu@panda:~$ dpkg -c linux-headers-3.5.0-12_3.5.0-12.12_all.deb |grep omap_drv.h14:27

ogra_hmm14:28
ogra_dkms seems to search for linux/omap_drv.h14:28
rtgogra_, linux-headers-3.5.0-12_3.5.0-12.12_all.deb is an install dependency for the flavour specific headers package14:28
ogra_and very likely under my kernel version (omap4) not under some x86 one14:28
ogra_rtg, well, i assume the prob is that i run a totally differen version on pandas ... 14:29
ogra_and dkms will likely look in usr/src/linux-headers-$kver/14:29
rtgogra_, yeah, we may have aconsolidated headers package for omap414:29
rtga consolidated*14:30
ogra_well, imho that header should really go into linux-libc-dev:armhf14:30
rtgogra_, because its a DKMS dependency ? I'm not sure that makes sense. its not used to build glibs or anything else is it ?14:31
rtgglibc*14:31
ogra_no, its only used to build the video driver14:31
henrixbrendand: just fyi, the precise kernel respin has been cancelled. we've decided to keep the patch i was reverting.14:31
rtgogra_, in which case you just need to adjust the include path14:32
rtgbut you know that...14:32
brendandhenrix - hmm, so we should still test 48?14:32
henrixbrendand: yep14:33
brendandhenrix - ok. bugs are being updated to reflect that i guess?14:33
henrixbrendand: yes, still working on that. i can ping you back when that's all done14:34
henrixbrendand: ok, everything should be updated now. let me know if you find any inconsistency.14:40
davmor2Hey guys anyone about who can help with this machine killing webcam I have?  I had the same issue in precise but it got fixed, but currently I can't complete the install process which will become more of an issue if the alternate cd goes away15:03
rtgdavmor2, do you know how it got fixed in precise ?15:11
ayanthere is a laptop going though the certificaiton process that has an unusual bug that after an s3 cycle, once you try to shut down, it will only reboot under precise.  i tried a few kernels from the mainline build page and the earliest kernel that doesn't have this bug is 3.4.1-quantal.15:11
davmor2rtg: no idea it was broken pre beta when I did a fresh install for beta it worked15:11
ayani tried bisecting between 3.4 and 3.4.1 using the precise configuration but NONE of the builds worked.15:11
rtgayan, cking is back tomorrow. he'll likely have some suggestions.15:12
ayanfinally, i tried manually budiling with the quantal kernel config and that build didn't have the bug.15:12
davmor2rtg: the annoying thing for me is that I ssh'd into the box prior to running cheese did tail -f /var/log/syslog and nothing the machine is killed so bad that not even ssh works :(15:13
rtgdavmor2, can you collect apport info on it ? you might have a crash in dmesg if its that messed up15:14
ayanrtg: i compared the two kernel configs and nothing seemed obvious. 15:14
rtgayan, you tried to build 3.4, or you tried installing 3.4 ?15:15
ayanrtg: i haven't built 3.4 but i tried one of the precompiled packages bulit for precise and it has the bug.15:18
ayanrtg: i might be interesting to build a 3.4 with the quantal .config.15:18
rtgayan, so the precompiled 3.41. _did_ work, right ?15:18
rtg3.4.1 *15:18
ayanrtg: but i think i've verified that the configuration is the culprit by building 3.4.1 with both.15:19
ayanrtg: yes, it does work.15:19
rtgayan, so the precompiled 3.4.1 likely started with the Precise config. apw - is that right ?15:19
davmor2rtg: will do15:20
ayanrtg: no, it started with the quantal configh iirc.15:20
apwrtg, it started with whatever the -series part of the directory name says it was15:20
apwbut it would have been the config at the build time15:20
ayanhttp://kernel.ubuntu.com/~kernel-ppa/mainline/15:20
ayanrtg: v3.4 goes up to -precise and -quantal starts at v3.4.1.15:21
rtgayan, how unfortunate :)15:21
apwthats helpful of me to change in the middle like that :)15:21
apwrtg, perhaps i should kick off a v3.4-quantal to allow comparison15:22
ayanrtg: yes. :^)  this has kept me up for about two days now.15:22
rtgayan,  I see a 3.4 Precise as well as a 3.4 Quantal. do they both behave the same ?15:22
ayanwow.  somehow i missed the 3.4-quantal.15:22
rtgapw, there is already a 3.4 Quantal15:22
ayani'll give it a whirl now.15:22
apwnow i am confused, i thought ayan said that v3.4 was precise15:23
rtgapw, thats the one he tried, but I think he missed seeing the 3.4 Quantal15:23
ayanya -- there is a v3.4 quantal in that directory.15:24
apwoh how nice of me to make both15:24
rtgapw, ayan, so if the Quantal config works then we know its not code, rather its a config difference15:24
apwrtg sounds resaonable indeed15:24

ayanrtg, apw: 3.4-quantal does not have the bug.15:37
rtgayan, well, bisecting between configs is gonna be a real pain in the ass15:38
apwayan, so 3.4-precise has it, and 3.4-quantal does not -- correct ?15:38
ayan(thought i thought i already confirmed this by testing 3.4.1 with quantal and precise configs. :^P )15:38
ayans/thought/though/15:38
ayanapw: correct.15:38
apwrtg, i would expect the differences that early to be small15:38
apwayan, so if you extract both of those .configs from /boot and compare them with diff15:39
rtgapw, true, damn near no-existent. is the tools set different ?15:39
apwhow bad is it15:39
ayanapw: i'll take a look now.15:39
apwrtg, we may have compiler changes too15:39
apwrtg, no both are built in precise chroots i think15:39
davmor2rtg: if you get a chance let me know if there is anything of any use there if not if there is anything I can do to get more info for you15:39
ayani wrote a tool to show differences and they were pretty dramatic between a recent quantal config and precise.15:40
ogra_rtg, -u doesnt create the initrd on some arches if there isnt a pre-existing one 15:40
rtgdavmor2, actually, I need the crash info _after_ you'ce started the USB camera15:40
rtgogra_, which is why I'm thinking just always use '-c'15:41
ogra_rtg, in other news, beyond the fact that we need the omap_drv.h file in linuc-ti-omap4, it seems we also miss http://dev.omapzoom.org/?p=integration/kernel-ubuntu.git;a=commit;h=0428bbdcdb53255b8b42a8ed73ab6ec1d897505415:41
ogra_rtg, right15:41
davmor2rtg: no probs I'll see if I'm able to trigger it and trigger apport via terminal or not15:41
ogra_(our omap_drv.h searches for omap_priv.h which is non-existing)15:41
davmor2rtg: Meh nope looks to be stuck at collecting problem info and now the system is unresponsive, I'll see if this finishes or not though15:45
rtgogra_, ok. isn't there a bug about the difficulties compiling against omapdrm ?15:45
ogra_not that i know of15:45
ogra_and if so, it would be outdated ... i just uploaded the first (supposedly) working pvr for quantal right now15:46
ayanrtg, apw: maybe this will be useful: http://pastebin.com/tKdi1PyK15:46
rtgogra_, then you should start one so we can track this (please)15:46
apwayan, could i have both of the v3.4-{precise,quantal} configs please15:47
ogra_rtg, will do, but i want to debuig that properly with rsalveti first15:47
ayanCONFIG_X86_MCE_XEON75XX ?15:47
ayanapw: sure.15:47
rtgogra_, ok. just assign it to me once you've created the bug and explained the issues.15:47
ogra_ok15:48
davmor2rtg: and now it's completely dead :(15:48
rtgapw, why are there _any_ differences in the final .config file ? its the same Kconfig's 15:48
apwrtg, it is starting from a different configuration shoved into the same valid options15:49
apwrtg, there is cirtainly the possibility of a different result15:50
ayanapw: http://zinc.canonical.com/~ayan/apw/15:50
ayand'oh.15:51
ayansorry.15:51
ayanuploading config from 3.4-quantal and 3.4-precise.15:51
rtgdavmor2, so this must be the built-in HP Webcam-101 that is crashing, right ?15:54
davmor2rtg: it is yes15:54
davmor2rtg: but it doesn't crash the app as such it's just the system stops responding to anything15:55
rtgdavmor2, which means its crashing the kernel somewhere15:55
davmor2rtg: indeed but I don't get all the flashing led like I would normally from a kernel crash and there is no apport data in /var/crash15:56
rtgdavmor2, that just means something has gone far more wrong then usual. could be a DMA wedging the PCI bus or something.15:57
ayanapw,rtg: http://zinc.canonical.com/~ayan/apw/  16:02
ayanthe are makred with -quantal and -precise.16:02
rtgdavmor2, it seems like this should behave as a standard UVC USB video  device. You say this works fine on Precise, right ?16:03
jjohansensconklin: okay I will look into it16:03
davmor2rtg: yeap and the first alpha too iirc16:03
rtgdavmor2, the first Quantal alpha was a 3.4 based kernel IIRC16:04
sconklinjjohansen: I prepped the meeting report for today without running the normal merge process I do, so no hurry16:04
rtgdavmor2, I've got an HP mini. lemme have a look at it.16:04
davmor2rtg: I can't be certain on the first alpha though. But I know alpha 2 onward I started using alternate as the desktop ubiquity would die on the webcam page16:06
rtgdavmor2, unfortunately mine is a different device, Chicony Electronics. I'm also not finding any crash reports in Google16:11
davmor2rtg: so Joseph just linked my bug to this one https://bugs.launchpad.net/bugs/87529716:12
ubot2`Ubuntu bug 875297 in linux "Ubuntu installer hangs on "Choose a picture" screen. Never recovers. Installation not bootable." [Critical,Incomplete]16:12

rtgdavmor2, can you disable the camera from the BIOS ?16:13
davmor2rtg: let me reboot the box I'll let you know16:13
davmor2rtg: Nope very few hardware settings16:15
rtgdavmor2, drat16:16
rtgdavmor2, so the bug jsalisbury has linked to has a different device. Furthermore its a USB 1.0 device whereas yours is USB 2.0.16:16
rtgdavmor2, in fact, that bug originated with 11.10, so I don't think its the same problem.16:18
rtgjsalisbury, ^^16:18
jsalisburyrtg, ack, I'll unlink it as a dupe16:18
davmor2rtg: so the uvcvideo module is the one I have however16:18

davmor2rtg: I can take a trip to the office at some point in the near future, I'll sort something out apw16:24
apwdavmor2, hmmm is this an installation issue or something which appears when installed16:25
davmor2apw: both16:25
apwdavmor2, and whats the known good/bad kernels at this point16:26
rtgdavmor2, you can work around it for now by using the alternate installer, then black listing the module before you reboot.16:26
davmor2apw: because there is a webcam page in the installer it kills that, but also cheese kills the system on an installed system16:26
davmor2rtg: that's what I did but the devs are looking to lose alternate soon so that won't be an option for much longer16:27
apwdavmor2, does rtgs work around make it work, or just get rid of your webcam16:27
rtgdavmor2, thats true16:27
apwrtg, what module breaks16:27
rtguvcvideo (I think)16:28
rtgapw, his machine wedges so bad that he can't get a stack trace16:28
davmor2apw: alternate works,  I can try and disable the webcam module as described in 875297 and see if I can complete the install via live if you want16:28
apwuvcvideo.__disable__=true on the kernel command line under F6 in the installer?  davmor2 ?16:29
apwthat sort of thing?16:29

davmor2apw: and iirc I was able to install alpha 1 I think it died after alpha 116:31
