apwRAOF, did sconklin drop you a line about the lid detect bug ?08:57
RAOFapw: Indeed he did.  I've replied, and cc'd you.08:58
apwahh then i'll read m'email08:58
* apw shouts at compiz which has dumped twice in two days08:59
RAOFapw: In short, I think it's possible to fix in a way that would minimise regression potential, and be acceptable upstream, but requires more work than the pseudo-patch I dumped in the bug.08:59

cooloneyikepanhc: as you are maintaining the #hwe tree, i got a question for you09:18
cooloneyikepanhc: when we got a new board defconfig and some small patches to enable a new board, 09:18
cooloneyikepanhc: do you just add a new flavor or something else09:19
ikepanhccooloney: for a custom kernel, its another branch, so I will have a new debian folder09:20
ikepanhccooloney: and restart the abi/changelog/flavour09:20
cooloneyikepanhc: ok, creating a new debian.project folder09:21
ikepanhccooloney: yeah09:22
cooloneyikepanhc: and if you got a new board which can be fitted into this project09:22
cooloneyshortly, this project has 2 boards,09:22
cooloneyboard-a and board-b09:22
cooloneywill you create 2 flavors for that?09:22
ogracooloney, if you are tlaking about the omap4 kernel above, the same omap4 kernel will run on both boards, dont bother with fiddling with different flavours10:46
cooloneyogra: the panda board use is own config file instead of the original one omap4_sdp_defconfig.11:31
ograthat will change11:31
ograjust ignore omap4_sdp_defconfig for that build 11:31
ograand use the panda one11:31
cooloneyogra: and we cannot generate 1 kernel to support that 2 boards. i just got a compiling failure11:32
cooloneyogra: yeah, that's what i am doing. 11:32
ograTI said it will be one kernel11:32
cooloneythanks for heads up11:32
ograprobably not yet though :/11:32
cooloneyok, it guess it will be panda, not sdp11:32
cooloneyno problem11:32
ograyes, main target is panda for 10.10 anyway11:32
cooloneyand one another thing is the panda config also got a problem11:33
cooloneyit built in both 8250 serial and omap serial driver11:33

Kanoapw: is it possible to change options based on enforce?12:27
apwKano, not currently is purely a check and abort function right now12:28
Kanoso how do you change options12:29
apwKano, add the new values by hand and updateconfigs normally12:31
Kanowhere to put the .config ?12:32
apwthere is a file called OVERRIDES you can put them in _temporarily_ then run updateconfigs, then remove it12:35

amitkapw: our build system is not an easy read anymore (for newcomers) :)13:51
apwamitk, bah of course it is :)13:52
amitkapw: that's like saying that "War and peace" is an easy read13:55
amitk:-p13:55
ericm|ubuntuapw, amitk, is there any easy way to extract the scripts of updateconfigs quickly into a separate script, so that multiple _defconfig can be used as input and a common.config and a bunch of <flavor>.config as output?13:57
ericm|ubuntuI guess that seems to be very useful for the ARM _defconfig mess we are now facing with13:58
apwericm|ubuntu, the processing works in that manner internally13:58
apwthere is a script to apply to a directory of configs13:58
ericm|ubuntuapw, which one?13:58
ericm|ubuntusplitconfig.pl?13:59
apwyep13:59
apwkernelconfig uses it so you can see how to13:59
ericm|ubuntuapw, thanks man - I'll take a look14:00
amitkericm|ubuntu: while it is worth looking into, I don't have high hopes that it will find too much common stuff.14:01
ericm|ubuntuamitk, well at least find a base to start the merge with14:01

JFoZhenya, do you have a bug filed about the issue?16:45
ZhenyaJFo: no i do not as i dont even know how to get all the details except for dmesg and i wanted to make sure it wasnt my hardware16:45
Zhenya(however this did NOT happen when i was on 9.10)16:45
JFoyou can run ubuntu-bug linux from a terminal window16:46

JFowe are still working out the bugs so to speak17:45
ckingno - it's easy peasy to use - thanks for making it fool proof17:45
JFowell, we try :)17:45
ogasawarajjohansen: so I'm sue you saw, but I've rebased our maverick kernel to 2.6.35-rc1 and will soon be pushing our rebase to 2.6.35-rc2...17:46
JFothe big thing is to make it super easy for you guys to get relevant and timely bugs to have a look at cking 17:46
ogasawarajjohansen: in my rebasing I spaced on dropping any AA patches like we'd discussed.17:46
ogasawarajjohansen: will that be an issue for you in bringing us up to date with the latest AA patches for 2.6.3517:46
JFoand the top 50 list at http://qa.ubuntu.com/reports/jfo/kernel-Top50.html is so you can have a look  at the overall workload17:46
jjohansenogasawara: yep, its not a problem17:47
ogasawarajjohansen: cool, phew17:47
jjohansenogasawara: we can either drop them separately or, patch on top, which ever works best for you17:47
jjohansenogasawara: probably best they didn't get dropped just yet anyways as I have some compatability bugs to work out17:48
ogasawarajjohansen: cool.  doesn't make much of a difference to me if we drop them separately or just a patch on top.17:49
jjohansenokay, I'll probably drop and do a clean import for you as that will give a nice clean history17:49
ogasawarajjohansen: sounds good17:49

jamincmy laptop appears to be periodically rebooting as a result of a kernel crash...  however most attempts to submit the requested bug report for the kernel crash result in a "HTTP Error 500: Internal Server Error" response after several minutes trying to upload the data.  Is there any other way I can report this problem and provide the necessary data?18:29
JFoI think you are encountering the same issue as Zhenya jaminc 18:31
JFothere seems to be some kind of server issue18:32
jaminck... wasn't sure if it was me or the server... it's an annoying issue... leave the system for a while and come back to find it rebooted at the login screen... no idea why... only report I have successfully uploaded indicated that my kernel was too old, though I'm pretty sure it was the most current at the time18:33
apwJFo, as we do not have any advanced topics i wonder if we should make 'Advanced' into 'Other'18:35
apwthen have essentially the same list of topics under 'Topics' on there18:35
apwhrm, perhaps not, what does that get me18:35

lamont wtf is up with that18:57
ckingtgardner, not sure if that patch will work - doesn't the pcmcia_request_irq require interrupts to be enabled to detect the IRQ probing?19:01
tgardnercking, as far as I could tell it did not. everything was just I/O reads and writes.19:01
ckingtgardner, ok - well, then I'm very happy with it ;-) Thanks for picking this up - I'm the slacker19:02
tgardnercking, lets see if it actually works :)19:02
ckingtgardner, if it does, the same code should be applied to a bunch of those drivers that use the same probing/config methodology 19:03
apwlamont, odd isn't it, i saw that when testing kvm myself.  i had assumed it was a udev/libvirtd interaction19:05
apwlamont, and therefore blamed kirkland 19:06
ZhenyaJFo: you mean on launchpad or kernel wise?19:11
apwtgardner, i think your script which adds ~lucid1 has gotten a little out of hand as its adding them everywhrere there is a ) ... should only apply on lines which do not have whitespace as the first character19:17
ckingJFo, I've dumped a readme file in the top level of the test suite - it's ready for you to play with19:18
bjfpgraner, if I go to http://voices.canonical.com/kernelteam/ i'm not getting any of the links on the right side of the page (so I can't go to admin and post) 19:23

smoseranyone around who can answer a quick question before i open it as a bug ?22:33
smoserjjohansen maybe 22:33
jjohansensmoser: whats up22:33
smoseri'm playing around with eucalyptus, and attaching a bunch of EBS block devices , detaching them, reattaching them.22:33
smoserthe block devices get (in udev) KERNEL=/dev/vda at first22:34
smoserthen vdb22:34
smoserthen vdc .... vdz22:34
jamincZhenya, hmmm can do both here... simply can't submit a kernel crash bug report22:34
smoserthey are never re-used22:34
jamincJFo thought we might be experiencing the same issue, but doesn't seem to be22:34
Zhenyajaminc: gotcha.i think they are ahving server isssues22:35
jjohansensmoser: hrmm, that seems wrong22:35
smosermy experience with other busses (scsi) is that when a block device was detached, and then reattached it would be freed.22:35
smoserok. i'll open a bug. just wanted to make sure it wasn't obviously working as expected from the kernel perspective.22:35
jjohansenyeah, that is generally the case22:35
jamincsmoser, esata doesn't reuse unless you explicitly tell the kernel to delete it22:35
smoserhm..22:36
jaminctry echoing 1 into /sys/block/${DEV}/device/delete22:36
jjohansenright there are some exceptions22:36
jamincthat's how I get the kernel to remove the old esata devices22:36
smoserwell, i'll open a bug, and let kernel deal with it.22:37
jjohansensmoser: subscribe me to the bug22:37
smoserjaminc, well, there is only at this point a /sys/block/vdag entry (no others)22:37
smoserso presumably i'd have to do that before the entry was removed.22:37
smosermaybe thats housekeeping that udev is supposed to do ?22:37
jaminchmmm I'd think the device names would be reused if the entry no longer exists...22:38
jamincis there a time limit on uploading lauchpad bug data via apport?22:40
