bgamarihow does one update a single module without repackaging the entire kernel00:21
bgamariI'm currently getting errors along the lines of: [    8.967377] dell_laptop: no symbol version for dcdbas_smi_request00:22
bgamari[    8.967380] dell_laptop: Unknown symbol dcdbas_smi_request00:22
Kanohi, could you disable commedi? the s626 module always locks up on my systems with saa7146 dvd card10:20
Kano05:00.0 Multimedia controller [0480]: Philips Semiconductors SAA7146 [1131:7146]10:22
Kanoalias:          pci:v00001131d00007146sv*sd*bc*sc*i*10:22
Kanois in s62610:22
Kanoand that locks up the system10:22
Kanousally controlled by budget-av10:29
apwsounds bad, that sounds like it needs a bug to remind me!10:30
Kanoas all my systems have got dvb cards none will boot ubuntu10:31
Kanoi prefer # CONFIG_COMEDI is not set10:32
apwmay well be something a lot of people hit10:33
apwlet me know the bug number and i'll have a look10:33
Kanomaybe there is another solution, like a complete alias with 4 ids10:35
Kanojust mailed the author10:35
apwcool10:35
Kanothis is definitely too generic10:35
Kanoall i can do is to disable it10:36
Kanosv*sd* is generic10:37
apwyeah it does seem rather overarching10:38
KanoCONFIG_HAVE_KERNEL_LZMA=y10:52
Kanohow about using that? would not hurt at all10:53
Kanoso rebooting to try without comedi10:55
Kanoit of course boots without s626. but how about updateing ndiswrapper to 1.5411:21
Kanostill 1.53 in there11:21
apwndiswrapper is on the list for review11:23
apwkernel LZMA would potentially affect slow machines11:24
apwa11:24
apwand would need testing on those platforms to check for regressions11:24
Kanonobody mentioned that11:24
Kanoi used that for -9 kernel for kanotix and really nobody metioned that it would be slower11:24
amitkKano: how many users does Kanotix have?11:28
Kanonot that many than ubuntu, but enough for me11:28
amitkKano: I was just curious. The larger the test base, the better.11:29
Kano118 kernel updates in logfile11:33
amitkI bet the majority of your users are very technical.11:35
Kanono11:35
Kanothey just like better support11:35
Kanoi provide support for fglrx for every kernel for example11:37
Kanonvidia of course too11:38
Kanoalso there are test image downloads with -9 kernel: 114 - 32 bit, 20 - 64 bit, 873 - combined, nobody mentioned slow loading speed11:42
Kanoit is interesting that these images are not officially announced ;)11:43
Kanobut rt2500usb seems to be really problematic11:46
Kanoany launchpad entries for that yet?11:46
Kanoi could fix one issue with removing ids from rt2500usb to use rt73usb for some cards, but those which are only in rt2500usb are still broken it seems11:47
Kanothats the only reason that somebody would downgrade currently11:48

nixternalanyone having issues with 2.6.30-10? black screen of death here...anything I can do to help triaging let me know..haven't found a bug yet concerning what I am seeing16:14
amitknixternal: KMS enabled?16:22
amitkwhat graphics card, etc."16:23
amitk?16:23
nixternalyou are on the right track :)   intel16:23
nixternaland yes it is a kms problem16:23
nixternalI just did i915.modeline=0 and it works16:23
rtg_nixternal: KMS doesn't work with PAE16:24
rtg_(yet)16:25
nixternalgotcha16:25
nixternalhopefully that is planned16:25
rtg_its in 2.6.3116:25
nixternalgroovy16:26
nixternalmaybe a blog post should go out to prevent frustration from people who will be upgrading in karmic in the next day or so?16:26
rtg_nixternal:  upgrades should not encounter the issue, unless you're running -server with desktop installed.16:27
nixternalI am not running -server, it is -generic16:28
amitkcurious16:28
rtg_nixternal: 2.6.30-10.11 ?16:28
amitknixternal: cat /proc/version_signature16:28
nixternal2.6.30-10.1216:29
nixternalUbuntu 2.6.30-10.12-generic16:30
amitknixternal: so PAE isn't enabled16:30
rtg_amitk: but KMS _is_ now enabled by default.16:31
amitkrtg_: true, but this particular case isn't because of a PAE/KMS conflict16:31
amitknixternal: ubuntu-bug xorg16:31
rtg_nixternal: I wonder if your Xorg package is not up to date?16:31
nixternalvery well could be16:32
rtg_nixternal: they have to be in sync16:32
nixternalxorg is 7.4~5ubuntu21 from the beginning of June16:34
nixternalthis issue happened right before it came time to enter my 3rd encryption password16:35
nixternalafter entering the 2nd password, the screen went black16:35
Unggnuhi all16:35
UnggnuIs there a reason why the sound driver power management is enabled per default in Karmic?16:36
amitknixternal: you are running karmic kernel and xorg on jaunty?16:36
nixternalno, this is all karmic16:36
amitkUnggnu: to save power? :)16:36
UnggnuIf you use headphones you really getting deaf through the clicking noise when it is enabled again16:36
amitknixternal: please upgrade your entire system and if it still persists, file a bug using 'ubuntu-bug xorg'16:37
UnggnuPlease don't do this automatically.16:37
amitkUnggnu: please file a bug to help us fix it.16:37
Unggnuok16:38
amitkUnggnu: you can disable it in your /etc/modprobe.d options16:39
UnggnuI have disabled it through proc16:39
Unggnuor sys16:39
amitkUnggnu: You can also disable it /etc/modprobe.d/alsa-base.conf (line saying options snd-hda-intel power_save=10)16:41
nixternalamitk: I did a dist-upgrade already, got everything that is available right now16:41
Unggnuok16:41
nixternalI will yell at Bryce and see what he is up to16:41
amitkhehe... ok16:41
amitkbjf_afk: having trouble compiling your kernel...16:45
Unggnuamitk: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/39118216:47
ubot3Malone bug 391182 in linux "Please disable Kernel sound power saving per default [Karmic]" [Undecided,New] 16:47
amitkUnggnu: do you use a laptop?16:48
UnggnuSure16:48
nixternalhahaha, amitk and rtg_: I didn't get the new initramfs-tools16:48
UnggnuI have also tested it in the past but disabled it because of this clicking16:48
amitkUnggnu: if so, the power savings can be quite substantial. In some cases almost 30-40mins of extra battery life.16:49
nixternalI just updated and got them and everything is working, though usplash is really small :)16:49
Unggnuamitk: Because of the sound card?16:49
amitkUnggnu: yes, the amplifiers, codec, etc.16:49
Unggnuamitk: My system uses not much power but the only important parts are cpu und display.16:49
Unggnuwhich really have an measurable impact if I remember correctly16:50
Unggnuand wlan of course16:50
nixternalI spoke to soon, at least I can hit all 3 encryption passwords now, but x is still dead16:50
Unggnuamitk: You can test it with powertop I guess16:50
amitkUnggnu: true. But try running your battery flat with and without the sound power savings.16:51
UnggnuI give it a shot :)16:51
amitkUnggnu: please post the battery life numbers to the bug, to allow us to judge how much the impact is16:52
Unggnuamitk: Anyway my ears would be more important for me than 1 W but I am testing :)16:57
Unggnu7.6 W with sound power saving17:00
Unggnuamitk: 7.6W with sound power saving and ~8 W without but the higher cpu usage might be also a reason17:03
Unggnuor 7.9W something around17:04
amitkcool17:04
UnggnuEveryone who needs this little difference can enabled it on his own. A gui entry would be the best of course :)17:04
=== bjf_afk is now known as bjf
amitkUnggnu: I'll leave it to dtchen to decide that. But in general if we can simply blacklist the ones that don't work that would be nice.17:05
bjfamitk, I'm trying to clear up the last of the config differences between Jaunty and Karmic w.r.t. imx5117:06
UnggnuThey work but there is  a reaction coupling if it gets enabled again which is very loud with head phones17:06
bjfamitk, I have not tried building for a bit, not surprised there are problems right now17:06
amitkbjf: ack17:09
amitkbjf: what I meant was it doesn't even start building. Asks me to run 'make mrproper'. Need to figure out what got hosed.17:10
bjfamitk, have not had that problem... however17:11
bjfamitk, I wonder if this is part of the config changes that were recently implemented17:11
rtg_amitk: isn't that 'cause you have cruft in your build root ?17:12
bjfamitk, in my working tree git says that I have made changes to other arch / flavour config files (I have not commited them)17:12
amitkrtg_: right. And I hard reset my tree. But no go17:12
nixternalamitk and rtg_: if I set 'nomodeset' by editing grub on bootup, everything works fine...fyi17:13
rtg_nixternal: I thought you said all worked fine after updating initramfs-tools?17:14
nixternalit started to work fine, but died when firing up X17:14
nixternalKDM17:14
amitkbjf: could you try 'debian/rules binary-generic' on your tree17:27
bjfamitk, i am having the same problem17:27
jaroHi there. Is there any suitable channel to ask questions related to quite old (2.4) kernel? I'm fighting with waitpid() not working correctly in a multithreaded process17:28
jaroand would like to find out if there is any known solution for this17:28
bjfamitk, the way I got pat it is I did 'debian/rules editconfigs' and just answered 'yes' when exiting to saving the config17:28
amitkjaro: google would be your friend for such an old kernel17:28
bjfamitk, I could build after that17:29
bjfamitk, should I run updateconfigs?17:29
jaroamitk: i did use it and found out one discussion thread that proposes that there is no way how to fix it17:29
bjfjust did that, let me commit those configs17:29
jaroamitk: I'd like to make sure that it is that way17:29
bjfamitk, ^^17:30
amitkbjf: yes, running updateconfigs is a good idea17:31
bjfamitk, ok, updates pushed17:31
amitkjaro: no one here will be able to help with a 2.4 kernel17:31
bjfamitk, wasn't expecting imx51 changes to ripple into the other config files17:32
amitkbjf: it should only touch the common arch files and common ubuntu files if it find the same options set in other arches17:33
jaroamitk: ok I thought so :-/17:34
rtg_amitk: 'missing' is also a matcvh17:36
amitkrtg_: aah, right. With apw's new patches17:36
apwwhats up?17:37
apwbjf yeah if you make changes to any arch config it could trigger changes in other arch common files17:37
apwif they now collapse to the same value or the inverse17:38
apwbjf if you are worried about what its doing shove the diff into a pastebin and i can see if i think its mental17:39
bjfapw, no worries, just unexpected17:39
rtg_apw: it shouldn't make changes in other arch common configs. armel should only affect config.common.ubuntu, right?17:39
apwrtg_, no it can affect other commons, if it stops something being common to all arches17:40
apwor if something becomes common to other arches17:41
apwlike turning on staging or something17:41
apwthen they will drop from the commons and move up to the ubuntu, or visa versa17:41
apwall depends on the actual value17:41
rtg_apw: ah, right. I was thinking more about missing features.17:41
apwyeah its likely something more generci he has changed, rather than something imx specific, which yes should just gently slide up to ubuntu level without affecting the other arches.  if its not then its bust17:43
bjfapw, rtg_, I've emailed you both the patch just so you can see what changed17:48
rtg_bjf: I was just looking at the commit in your git repo17:49
bjfrtg_, you could do that also :-)17:50
rtg_apw: its interesting what happened to some of the configs. for example, CONFIG_CHARGER_PCF50633 was removed from config.common.ubuntu and was added to the various x86 configs. If it was missing in armel, why didn't it stay in the common config?17:52
* apw waits for the email ... grrr17:53
apwit should have stayed ... which kernel is he based on?17:54
apwbjf, whats your current baseline?17:54
apwsha1 is fine17:54
bjfapw, it's off of karmic but probably a week old17:55
apwok then you have amitk's changes and not mine so the effect will be different17:55
apwyou may have trouble if you are not at the tip17:56
apwas the config split has changed17:56
bjfapw, so I'll need to rebase at some point and the another "updateconfigs"?17:56
rtg_bjf: ah, you definitely need a rebase.17:56
apwhopefully you have nice clean mods and only one updateconfigs in thee17:57
apwthere17:57
rtg_yeah, drop the updateconfigs commit17:57
bjfrtg_, right17:57
rtg_before rebasing. 'rebase -i' is your friend17:57
apwif you find the rebase is a nightmare for the configs we may be able to do something clever using the generated configs17:57
apwas the configs are in the standard format in the middle of a split and we can compare those with some little mods17:58
