| diwic | hi, what's the easiest way to look at the assembly code for a function in the precise kernel? | 09:53 |
| diwic | never mind, found it | 10:20 |
| Hauke | where do I find the git repo this change was mad against? http://patchwork.ozlabs.org/patch/182913/ | 11:13 |
| Hauke | for kernel 3.7 CONFIG_MEDIA_USB_SUPPORT should also be activated | 11:14 |
| Hauke | and CONFIG_NF_NAT_IPV4=m | 11:17 |

| sforshee | Hauke, if you haven't found the git repo for those config changes yet it's git://kernel.ubuntu.com/ubuntu/kteam-tools.git | 12:22 |
| ogasawara | rtg: bah, I'll send an update. | 12:46 |
| rtg | ogasawara, I had to chuckle when I saw that given our previous conversation. | 12:46 |

| needhelp112 | hello | 13:38 |
| needhelp112 | maybe somebody can help me: | 13:39 |
| Hauke | sforshee: thanks for the link | 13:40 |
| needhelp112 | can somebody explain me, where i can find the implementation of the wireless lan active scanning interval? | 13:40 |
| needhelp112 | i've seen that different devices are sending probe request (active scanning for access points) in different intervals | 13:41 |
| needhelp112 | but, i don't know where the "scanning behavior" is implemented | 13:42 |
| needhelp112 | maybe somebody can help me? | 13:42 |

| Hauke | http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc1-quantal/ misses linux-headers-3.7.0-030700rc1_3.7.0-030700rc1.201210161007_all.deb | 14:31 |
| rtg | Hauke, might be awhile before we get to that. apw is working on release tasks. | 14:34 |
| === henrix is now known as henrix_ | ||
| apw | hmmm | 14:47 |
| === henrix_ is now known as henrix | ||
| cking | apw, hmmm? | 14:55 |
| apw | cking, lack of headers, odd | 14:55 |
| cking | ah | 14:56 |
| Hauke | rtg: thank's for the info | 14:56 |
| sforshee | apw, missing headers seems to be due to some reorganization of drivers/media. Some cp commands referencing that path are failing. | 15:01 |
| marrusl | hi folks... I have some reports of random ivybridge system freezing esp under io load, but hard to pin down. And I have to say I'm seeing the same pattern on my sandybridge asus. | 15:02 |
| marrusl | seems like some fixes have been released for freezing issues, but they don't seem to be gone. just curious if there were other current open bugs... what I can do to help, etc. I'm trying mainline 3.6.2 right now on my machine. | 15:03 |
| marrusl | my customer seems to be having success with mainline/v3.6.1-quantal/ | 15:04 |
| apw | sforshee, indeed we sort of knew that headers change was coming | 15:06 |
| jsalisbury | marrusl, I can perform a revers bisect since there is success with 3.6.2. We just need to identify the last version that had the bug. | 15:07 |
| marrusl | jsalisbury, it's not direct to reproduce, but I have a couple of ideas to do so. | 15:08 |
| jsalisbury | marrusl, it would be good to know the results of 3.6.2 and 3.5.7 | 15:08 |
| jsalisbury | marrusl, ok | 15:08 |
| marrusl | jsalisbury, it seems to me that for a while now, whenever I install a new KVM machine, my system performance just dies. and I do get syslog messages. | 15:09 |
| marrusl | jsalisbury, ok, then we should be able to further trace the commits back to 3.2? | 15:10 |
| jsalisbury | marrusl, sure if that is when this issue started happening. Does it happen in Precise? | 15:11 |
| marrusl | jsalisbury, we'll have to see if my problem is precisely the same as the customers. they are ivybridge/precise , I'm running sandybridge/quantal. | 15:11 |
| marrusl | the descriptions are really feel similar (I know, i know...) | 15:11 |
| jsalisbury | marrusl, ahh, ok | 15:11 |
| apw | psivaa, hey ... i've just asked for some dmesg's on that boot race thing | 15:11 |
| marrusl | but yeah, i have no idea if it's the same. or if we're looking at a whole pack of bugs. | 15:12 |
| * marrusl shakes fist at intel | 15:12 | |
| psivaa | apw: sure ill add them to the bug | 15:14 |
| * smb wonders about this connection still working... | 15:20 | |
| * smb waves to cking | 15:21 | |
| cking | smb, it seems to be working | 15:21 |
| smb | Ah good, it seems all of Canonical was gone for a moment... | 15:22 |
| bjf | smb, mumble keeps dropping on me here | 15:22 |
| smb | bjf, Well I claims to be up for me, but nobody would answer my screams... :) | 15:23 |
| bjf | smb, i don't see you in my mumble client | 15:23 |
| smb | Ah, now it realized it is in trouble | 15:23 |
| psivaa | apw, the dmesg's are attached now, sorry i had to do a fresh install, hence the delay | 15:57 |

| * sforshee is reminded he has parent-teacher conferences today, back later | 16:10 | |
| * ppisati -> gym | 16:15 | |
| cking | bah, mushed up my chroot | 16:16 |
| marrusl | jsalisbury, ha. already had a gpu lockup (which wasn't a symptom before) on 3.6.2. | 16:18 |
| marrusl | maybe i should try something else. | 16:19 |
| jsalisbury | marrusl, Maybe test the Precise kernel to see if you can reproduce the issue like the Customer? | 16:21 |
| marrusl | jsalisbury, is there a 3.2 build for quantal? | 16:22 |
| marrusl | reinstalling is not appealing. though I won't rule it out. | 16:22 |
| jsalisbury | marrusl, sure. You should be able to install any of the 3.2 kernel debs on a quantal system. | 16:22 |
| jsalisbury | marrusl, One second, I'll post a link to all the Precise kernels. | 16:22 |
| marrusl | jsalisbury, whew | 16:22 |
| marrusl | yes, I assume this will be beyond the powers of apt | 16:23 |
| jsalisbury | marrusl, This is the top level page for all Ubuntu releases: | 16:23 |
| jsalisbury | https://launchpad.net/ubuntu/+source/linux | 16:23 |
| jsalisbury | marrusl, Precise specific kernels are at: | 16:23 |
| jsalisbury | https://launchpad.net/ubuntu/precise/+source/linux | 16:23 |
| jsalisbury | marrusl, Drill down into the specific kernel version under "Releases in Ubuntu" | 16:24 |
| jsalisbury | marrusl, on the next page, drill down for your arch under "Builds" | 16:24 |
| marrusl | this thread seems to be on point... I've been seeing "CPU0: Package power limit notification (total events = 159)" for a while | 16:24 |
| marrusl | https://bbs.archlinux.org/viewtopic.php?pid=1176631 | 16:24 |
| marrusl | well, i'll get more details as I go. | 16:25 |
| Eimann | is there any reason why the non-platform specific headers package isn't build properly in the daily builds at the moment? | 16:34 |
| * Eimann checks the build.log | 16:34 | |
| Eimann | apw: do you know this out of your head? I don't see anything strange with dh_builddeb | 16:39 |
| apw | Eimann, for 3.7-rcX? yes the headers have moved | 16:39 |

| Eimann | apw: yes 3.7-rc | 16:52 |
| Eimann | http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ | 16:53 |
| apw | yep headers have moved upstream and will take a bit of fixing | 16:55 |
| kamal | rtg: regarding Kyle Fazarri's Cypress driver pull requests ... You say we should only use the "cherry picked from" syntax for refs into Linus' tree? Precise commits shouldn't include "cherry picked from" references to Quantal master branch? (Do we not consider quantal master immutable at this point? I'm not arguing, just trying to fix my own mis-understanding). | 16:58 |
| rtg | kamal, Quantal is only just now immutable, but as a rule of thumb commit without context are always from Linus' repo | 16:59 |
| rtg | commits* | 16:59 |
| === bjf[afk] is now known as bjf | ||
| kamal | rtg: ok, got it. so we note that you ACK'ed both of the SRU's anyway despite that glitch, and despite the improper BugLink: syntax. Should we clean them up and re-submit, or will you make those fixes for us at apply time? | 17:03 |
| rtg | kamal, I'll fix them when I apply. I was just awating a second ACK (which I now have) | 17:04 |
| kamal | rtg: got it, ok thanks very much\ | 17:04 |
| rtg | kamal, I'm currently working on squashing ubuntu-r which has about a bazzilion commits | 17:04 |
| kamal | rtg: yeah, you have fun with that :-) | 17:04 |
| rtg | kamal, its a giant pain in the ass | 17:05 |

| zenx | I am trying to build util-linux but it gives an error compiling. Checking the logs it mentions that uclibc was built without large file support but I have it selected in the config | 19:21 |
| zenx | ups | 19:22 |
| zenx | wrong channel | 19:22 |
| rtg | ogasawara, pushed ubuntu-r with a major fold down. I've still got a few of the patches that I need to breakup before I can finish folding down the debian directories. This insight has given me some thoughts on how to judge incoming config patches, i.e., break them up if they're gonna write outside the deian directory (as many of our ubuntu directory patches do) | 20:21 |
| * rtg -> EOD | 20:21 | |
| ogasawara | rtg: ack | 20:21 |
| ogasawara | rtg: I thrown down a note in the config blueprint I file to remind us to chat about it | 20:21 |
| rtg | ogasawara, good | 20:22 |
| maxb | Is it possible to have update-initramfs search and use modules from /lib/modules/$(uname -r)/extra ? | 22:30 |
| maxb | I have a really really weird problem on an Asus UX21A ... Pressing Fn+F5 ("brightness down") works as expected but Fn+F6 ("brightness up") when pressed multiple times seems to block further hotkey events for a few seconds. I've chased this as far as seeing that the delays are visible in the ACPI events viewed via acpi_listen. Can anyone suggest further things to look at to figure out whether or not this is a BIOS problem? | 23:36 |
