akgranerapw ping08:56
apwakgraner, hi08:57
akgranerapw - I tried the kernel you asked me too - no overheating08:57
apwakgraner, exceelent, i'll tell bisect 'good' then and get you another one ...08:58
akgranerokie dokie - I didn't try using wireless as that didn't seem to be an option with the one you gave me08:58
apwakgraner, hrm odd08:59

apwakgraner, building ...09:00
akgranerokie dokie - I leave for Ohio in like 12 hours - but will test what I can before I leave09:00
apwAnAnt, to get that on the dev teams radar it should be emailed to kernel-team email list requesting its consideration for maverick09:02
AnAntapw: thanks09:03
apwAnAnt, i'd refer you to the FAQ question on 'how can get requesti a patch be included in the ubuntu kernel?" but there doesn't seem to be one!09:05
apwAnAnt, there is: https://wiki.ubuntu.com/Kernel/FAQ/DevHowToPatch09:08
AnAntapw: thanks, according to  Kernel/Dev/KernelPatches , I should refer to upstream thread that discussed the patch, but I know nothing about it09:11

* cooloney just installed daily-live iso of maverick on his inspiron 1012, but found kernel doesn't find the Network Wired controller09:47
ckingcooloney, what wifi chipset do you have?09:48
cooloneyso there is no network on my laptop09:48
AnAntapw: thanks again09:48
cooloneycking: wifi controller is in my lspci list09:48
apwcooloney, no wired controller did you say?  which one is it normally09:49
cooloneybut failed to find the wire network controller in my lspci09:49
cooloneyapw: no wired controller09:49
apwright, but there is one, what one _was_ it before it wasn't there09:49
cooloneyapw: i have to search in the google, hold on09:51
apwcooloney, 1012 is a new mini10 yes09:51
ckingisn't that broadcom wl?09:51
apwcking, can you hear me ?09:51
apwakgraner, ok am pushing a 'bisect2' kernel to the same place, will be there in about 10 mins09:54
akgranerapw - thanks!09:55
apwakgraner, late there isn't it ?09:55
akgranerearly almost 5am09:55
* cking wonders if akgraner ever sleeps09:55
apwakgraner, sorry any time before 6 is late not early09:55
ckingtime is relative ya know09:55
apwakgraner, you getting up at 4 now ?09:56
akgranercking, I do :-) but I won't be here this weekend so I have lots of notes and to do lists to leave for *everyone* :-)09:56
akgranerapw, yep something like that - kids are back in school and Becca had to be at school by 0645 the last 2 weeks for drivers ed09:57
cooloneycking: /winxp/1509:57
apwakgraner, just say no09:57
ckingcooloney, eh?09:57
apwcooloney, that doesn't sound like the name of a controller to me09:57
cooloneysorry, &_&09:58
amitkakgraner: 5am, eeeeeks! I haven't seen that time on my clock ever unless I've stayed up all night09:58
akgranerplus I wanted to be up early to test the kernels from apw before I head to OLF in case something weird happens - since my computer will be with me09:58
* cking thought time between midnight and 6am did not exist09:58
apwakgraner, just make sure you download the offiical good kernel that was the latest good one, and keep it as a .deb on your machine09:59
jjohansenno no its the time between 6am - 8am that doesn't exist09:59
cooloneyapw and cking, lspci http://pastebin.ubuntu.com/490836/09:59
apwjjohansen, you can talk09:59
akgranerapw will do :-)09:59
jjohansenwho me :)09:59
cooloneyapw and cking, dmesg -> http://pastebin.ubuntu.com/490838/10:00
apwcooloney, its not there, as you said, but that doesn't help10:00
apwcooloney, this is a dell mini 10v new version yes ?10:01
apwif so then its likely its an rtl813910:01
cooloney05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)10:02

akgranerapw awesome same place as before?10:13
apwakgraner, yeah, bisec210:13
apwbisect210:13
akgranerlooking now  - downloading now :-)10:14
akgranerdo I need both header files10:14
apwthe second one may help wireless work as you have bcmwl10:15
akgranerso the one that says all? or just the i386?10:15
apwi'd get an install all three bisect2 .debs10:16
akgranerroger that10:16
akgranereverything is downloading now10:16
akgranergive me just a few and I'll reboot and see what happens 10:17
apwakgraner, no rush as and when you get a chance10:17
akgranerapw if I don't do it now - when the sun comes up  - something shiny will go by and you'll have to remind me :-)10:17
cooloneyapw and cking, so weird. in lucid live cd, wired ethernet still missed10:23
ckingcooloney, were you running lucid on this before you installed maverick?10:26
cooloneycking: yes, ethernet works fine before10:26
ckingmost curious10:26
cooloneyafter i installed maverick today, it's missing10:26
ckingcooloney, I suggest unplugging the power, taking out the battery, completely powering it off and retry10:27
apwcooloney, cnd has one of those machines, might want to ask him if his net is ok10:27
ckingcooloney, are you booting with the ethernet cable already connected or not?10:28
slacker_nlfor those who want/need to know: the generic kernel in -proposed on lucid works for me :)10:29
akgranerapw, this one will be listed as 32-23 as well correct?10:32
akgranerI installed it and selected it but still no wireless - will boot back into the new kernel and try connecting wired this time brb10:33
apwakgraner, yeah same name10:34
cooloneycking: let me try your method10:37
cooloneyapw: cnd has a final product, mine is an engineering sample10:37
apwahh10:37
ckingbound to work then ;-)10:37
ckinggot the latest BIOS on it?10:38
cooloneycking: i think so, if it still fails, i will check the BIOS 10:38
apwand chceek its not disabled in the bios all of a suddent10:40
cooloneycking and apw, nice, i got my wired controller back after uninstalling the battery10:46
apw!10:46

cooloneyapw: yeah, maverick10:46
=== amitk is now known as amitk-afk
akgranerapw, my machine is about 61 degrees Celsius with the new kernel - with 22 it hovers around 48 but 61 is better than 9011:17
apwhrm, not convinced that means its good or not11:18
apwakgraner, ^^11:18
akgranerhad to boot back into 22 to get back online though  - so now I am back to 48 11:18
apwcould you run while :; do :; done in a terminal window and see what it does11:18
apwi suspect that one may be bad11:18
akgranerapw okie dokie brb11:21
akgranerapw, I ran that command at got into the 70's before I stopped it11:32
apwakgraner, so that sounds like a bad kernel to me then11:33
akgraneryep I believe you are correct11:33
akgranerI rebooted back into 22 for now11:33
apwyep, told the bisect its bad11:33

=== ivoks is now known as ivoks-afk
apwilmari, the async patch was pretty small, so i'd be supprised if its hard to apply12:59
apwwhats the fix for13:00
ilmariapw: changing battery capacity units13:00
apwilmari, got a pointer to the patch ?13:00
ilmarihttps://patchwork.kernel.org/patch/119791/13:00
ilmariapw: it adds an argument to the acpi_battery_update function, which is what is being called asynchronously13:01
apwahh a pain indeed13:01
ilmarieasiest would probably be to create another async function that calls it with that argument13:01
apwilmari, patchworks seems to be dead13:01

pgranerapw, you narrowing down akgraner's problem?13:02
ilmarithe patch link fails, but the mbox link works13:02
apwpgraner, slowly but shurly, she is testing a third bisect point13:02
ilmarihm, it seems to be intermittent13:03
ilmariapw: try again13:03
pgranerapw, how many patches are you down to now?13:03
apwpgraner, still loads13:03
pgranerapw, yikes13:04
apw80 or so i'd guess, but we started at about 400 so we're getting there13:04
apwpoke her to report her testing on this one :)13:05
pgranerapw, she's testing it now13:05
pgranerapw, I have to keep telling her the dpkg incantation to install the bits... 13:05
apwheheh13:05
* pgraner feels like a scratched cd13:06
akgranerthe up arrow key is a beautiful thing 13:06
* pgraner is trying to be hip and updated... so I used that instead of a broken record13:06
apwpgraner, heh should be a 'looped mp3' surley13:10
* apw cannot see any patches in the good->bad range that make any sense as the cause ... lets hope the bad is right13:11
pgranerapw, yea, its got to be something obscure13:12
* ilmari will have a go at porting the acpi battery patch later (but not today)13:12
apwilmari, may be easier to pop the async patch, apply it and fix that one as it goes on13:13
akgranerapw, installed and ran a script based on the command you gave me earlier - it got up to 74 degrees in less than 5 mins13:15
apwakgraner, and if you run it now on the -22 known good one ?13:16
akgranerlet me find out brb13:17
akgranerapw, with the script it is hitting 75 with the script running on -2213:24
apwso ... its likely this and the previous 'bad' was actually a good13:24
apwto confirm that you could go to your latest kernel which is deffo bad and doing the same test13:24
apwakgraner, ^^13:25
akgraneryep - I think it's -2513:25
akgranerwill do that now13:25
apwthanks, if we are 'bad'ing when we should be 'good'ing we'll be here forever13:26
akgranerapw with the latest kernel - I hit the 70's with the script in less than 10 seconds13:29
apwok ... so thats the test then 70 in seconds == bad, 70 in 5 mins == good13:29
apwso i've reversed the previous bad to a good, and will get you a new kernel shortly13:30
akgranerso do I start timing with 22 and go forward when I get the new kernel?13:30
apwwell we know -22 is 5 mins, and we know that the previous time we said 5 mins was bad, so i've redone the bisect changing that to a good result13:31
apwthe next kernel just need to know if its 5 mins or 10s to 7013:31
apwthe former == good, latter == bad13:31

bjfdiwic, i've got nothing, i have pretty much just ignored the summit completely15:48
diwicbjf, okay. I'll hold it. Let's see if anyone shows up. Do you think what's in that email is a good outline of what people would like to hear on a triage session?15:49
JFodiwic, no15:52
JFolernid is just a tool that folks can use to watch the class15:52
JFodiwic, even if it seems no one is watching, the show should still be done since we keep a log of the class so that people can look later15:52
diwicJFo, okay, I'll just spare the work needed to create slides then15:53
JFoyeah, unless you already have something, I'd just chat about sound15:53
diwicJFo, I have an outline of what I want to talk about, hopefully bjf is reviewing it right now.15:53

jjohansenck, no official team needed, but it is good to subscribe to the mailing list19:57
jjohansenotherwise all your mails will have to be moderated19:57

ckyou said something about "choose something you are interested in", does that mean I should be surfing around Launchpad?19:59
jjohansenck: well you can if you are interested in bugs20:00
apwyeah remember a distro kernel is mostly an integration and publishing exercise, the meat of the work is bug related20:00
jjohansenck: basically, just find bits and pieces you are interested in, maybe you want a specific patch from upstream in, maybe you like hacking audio20:00
jjohansenso, you target those areas, perhaps work with upstream, or just bring missing bits to our attention20:01
jjohansenas apw said most of the distro kernel work is integration and bug work, but you don't have to do that20:02
jjohansenif you are doing this on your time, have fun with it, pick things that interest you20:02

krieblyHi there, I was wondering if I need to be concerned about "CVE-2010-2960 keyctl_session_to_parent NULL deref system crash" with Ubuntu 10.4/Lucid's linux-image-2.6.32-24-server (amd64)23:17
ubot2kriebly: The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel 2.6.35.4 and earlier expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-2960)23:17
