|---|---|---|
| mfilipe | my kernel is 32bits-pae | 02:16 |
| Sarvatt | mfilipe: /boot/config-3.0.0-whatever-generic | 02:17 |
| mfilipe | Sarvatt, thanks a lot! :) | 02:17 |
| Sarvatt | replace whatever with a number of course, dont know what kernel you're using :) | 02:17 |
| mfilipe | Sarvatt, default... 3.0.0. I found the config | 02:23 |

| TeTeT | a customer reports random freezes on x220 (sandybridge) with 10.04 and lowell and natty-backports-lts kernel. Is there any magic sysreq thing I can ask them to run to gather useful info from the crashed systems? | 08:30 |
| smb | TeTeT, Depends a bit on what really happens. Is it freezing (desktop only or whole system) or a crash. First may show not much and if the whole system is frozen, the sysrq keys don't work either. | 08:34 |
| TeTeT | smb: ok, seems system is completely frozen, e.g. ssh doesn't work any longer. Only at times the mouse pointer remains moveable | 08:35 |
| smb | TeTeT, So one thing to try could be to ssh in before and do a tail -f on the syslog and hope to catch something there. | 08:36 |
| TeTeT | smb: ok, good thing to monitor in real time, I'll suggest that, maybe using the remote option of rsyslog as well | 08:36 |

| smb | morning | 09:14 |
| smb | cking, You know what, I fixed the jumbled characters in my battery readout that caused udev to go wild... | 09:15 |
| cking | smb, how? | 09:21 |
| cking | smb, was this a user space fix or in the kernel? | 09:22 |
| smb | cking, Removing the battery for a while... Now the strange characters are gone... :/ | 09:22 |
| cking | oh | 09:22 |
| cking | that's kinda amusing | 09:23 |
| smb | So it was a hardware fix... :-P | 09:23 |
| cking | still, the udev issue still needs to be fixed IMHO | 09:24 |
| smb | Wished I had thought of that last week. Would have saved me the annoying stop/start cycles on udev | 09:24 |
| smb | I tend to agree, there must be a way to stop a call that has a permanent issue instead of repeating it | 09:24 |
| apw | jjohansen, hello | 09:31 |
| smb | morning apw | 09:32 |
| apw | morning | 09:32 |
| Kano | hi apw , could you take a look in pata_of_platform.c ? | 10:47 |
| Kano | apw: it seems there must be a 32 bit error? | 10:48 |
| ppisati | herton: hold on for the omap4 kernel, i'm respinning it | 11:32 |
| herton | ppisati: ok, it's ok to respin it, that problem in the changelog should be fixed | 11:35 |
| ppisati | herton: yep, but Tim pushed the Linaro revert on top of the previous version, let inclue that patch too | 11:36 |
| ppisati | *let me include | 11:36 |
| herton | ppisati: ok, see if there is an abi change needed also because of the change, may be not, I'm not sure but I think abi check is enabled for this one (only disabled for armhf from what I saw yesterday) | 11:37 |
| ppisati | no abi changes | 11:38 |
| herton | ok cool | 11:38 |
| ppisati | herton: ok, all done | 11:57 |
| herton | ppisati: ack, thanks | 11:58 |
| ppisati | herton: and it passed the verify-release-ready test | 11:58 |
| herton | ppisati: tim pushed the patch to you? it misses the signed-off (may be I'm being too pedantic now) | 12:19 |
| ppisati | herton: nope, it's alreadi in ubuntu-oneiric/ti-omap4 | 12:32 |

| apw | cking, about ? wondering about resurecting the kernel power consumption blueprint, as a bucket for your workitems | 13:02 |
| apw | seems the logical thing to od | 13:02 |
| tgardner | ogasawara, given Rick's test policy, do you suppose we should delay uploading precise until about -rc2 ? | 13:56 |
| ogasawara | tgardner: that sounds safer | 14:02 |
| tgardner | ogasawara, shall I rebase against -rc1 ? I'd like to get some master-next testing under way | 14:02 |
| smb | Though potentially that policy does not apply to us as I think they say Ubuntu developed sw | 14:02 |
| ogasawara | tgardner: go for it | 14:03 |
| tgardner | smb, folks will howl anyways if we break their kernel | 14:03 |
| ogasawara | tgardner: gimme 5min to push the reverted ntrig patches | 14:04 |
| tgardner | ogasawara, ack | 14:04 |
| smb | tgardner, That is true. Even more if it stops booting... So to wait an rc sounds like a save play | 14:04 |
| smb | tgardner, Btw, not sure whether you would still look at it but 2.6.32.47 feels like soon being followed by a fixup .48. Some patches seem to break builds... | 14:07 |
| tgardner | smb, yep, saw that. armel failure, right ? | 14:08 |
| smb | tgardner, Well that and an allmodconfig explodes on my amd64 build in some soc module | 14:08 |
| tgardner | smb, if it builds for our configs, and doesn't break omap3, then its likely still worth applying. | 14:09 |
| ogasawara | tgardner: pushed | 14:10 |
| tgardner | ogasawara, ack | 14:11 |
| smb | tgardner, Not sure whether we would hit those (well the first one likely). I have not yet tried any builds on our side. I'd probably delay until it is fixed, then I can push a fixed up drm33 and we could use that one. | 14:12 |
| tgardner | smb, do you have some drm patches for this next stable update ? | 14:13 |
| smb | There is two drm fixes from Debian that I would add as well. And then it might just be one run on the formal (tracking side) | 14:13 |
| tgardner | ok | 14:13 |
| ogasawara | tgardner: fwd'd you a patch from apw to fix a 3.2-rc1 build failure | 14:14 |
| * smb finds it scary to start answering tgardner questions before he asks them... | 14:14 | |
| tgardner | smb, she's just that good | 14:14 |
| smb | tgardner, I do not count me as a she... ;-P | 14:15 |
| tgardner | smb, thought you were talking about ogasawara | 14:15 |
| * apw looks vague | 14:15 | |
| smb | Nah, I was typing the answer to the drm question when you asked it | 14:16 |
| smb | Of course I am not that fast of a typist so I did not beat you on pressing enter | 14:16 |
| * smb wonders whether he needs to slap apw... | 14:16 | |
| * apw sends smb a typing tutor | 14:16 | |
| apw | smb, always | 14:17 |
| tgardner | apw, how's the custom binary maintenance prototype coming? this epoll patch continues to clog my folder. | 14:17 |
| apw | tgardner, heh i was just checking that branch out ... | 14:17 |
| ppisati | tgardner: can you install u-boot-tools on tangerine inside the oneiric-amd64 chroot? need it to create the uImage kernels for arm (when i'm building from vanilla) | 14:49 |
| tgardner | ppisati, done | 14:52 |
| * ogasawara back in 20 | 15:05 | |
| apw | tgardner, ok so i have a prototype basically working. i am a little concerned about the semantics | 15:59 |
| apw | tgardner, essentially we have two options, either clean creates the patches, or we have a 'refresh' option you use for this function | 16:00 |
| apw | in the first instance things are automatic, but local test builds you need to know you need to push the dependant branches also | 16:00 |
| apw | in the latter you need to know to refresh them when changing things, which can be inforced at insertchanges time | 16:01 |
| apw | but testing is much more 'as it is now' | 16:01 |
| smb | I'd tend towards the refresh option... | 16:02 |
| ogasawara | are we having a meeting today? | 16:03 |
| apw | ug i hope not :) | 16:03 |
| smb | It would be in one hour, or? | 16:03 |
| apw | bjf, is the master of all things meeting | 16:03 |
| bjf | ogasawara, who would run it? | 16:03 |
| ogasawara | bjf: I don't know if we actually decided who's running the meetings now | 16:04 |
| * jussi waves to ogasawara | 16:04 | |
| apw | oh did bjf abdicate ? | 16:04 |
| ogasawara | apw: he did | 16:04 |
| * ogasawara waves to jussi | 16:04 | |
| * smb missed that, too | 16:04 | |
| ogasawara | I don't think it was widely circulated that he stepped down from being the chair | 16:05 |
| apw | well i am pretty sure noone wants to do it, so perhaps we need to return to a rotating chair | 16:05 |
| ogasawara | I vote that we postpone till next week. I'll chair. | 16:05 |
| bjf | ogasawara, smb and apw were at the same table with me at plumbers when i made the statement :-) | 16:06 |
| apw | ok, works for me. we need to make sure its nice and documented to the untrained eye so we can rotate it | 16:06 |
| smb | bjf, probably too drunk then... :-P | 16:06 |
| apw | plmbers, plumbers, you expect me to remember that far back ? | 16:06 |
| bjf | smb, could be though it was in the a.m. at the hotel | 16:07 |
| === kamalmostafa is now known as kamal | ||
| cking | I recall bjf saying it | 16:08 |
| smb | bjf, Oh, morning bah... | 16:08 |
| jussi | DO you peoples use the meeting bot for your meetings? (meetingology) | 16:09 |
| apw | cking, heh then you should have reminded us :) | 16:09 |
| apw | jussi, yep | 16:09 |
| bjf | jussi, the new bot sucks | 16:09 |
| cking | ...and I thought "if it I join the kernel team it means somebody as disorganised as me running the meeting == fail" | 16:09 |
| jussi | bjf: how so? | 16:09 |
| bjf | jussi, the output is ignored | 16:09 |
| jussi | bjf: more specific pleasE? | 16:09 |
| apw | it does tend to stomp all over what you are trying to read by repeating everything and chainging the topic all the time | 16:10 |
| bjf | jussi, we developed our own scripts for deailing with the meeting output, the bot doesn't come close to producing the same, so I/we just ignore it | 16:10 |
| apw | quite why it does that i am unsure | 16:10 |
| jussi | bjf: and if there are specific issues, bugs would be super. | 16:10 |
| apw | for me the issue it about once a year we get a new format out of it | 16:11 |
| jussi | bjf: so you dont like the wiki output the bot makes? | 16:11 |
| jussi | AlanBell: ping | 16:11 |
| apw | which is just a pain. we already had to make something make what we wanted to cope with the old | 16:11 |
| bjf | jussi, no, it's not helpful | 16:11 |
| jussi | (AlanBell is the author fyi) | 16:11 |
| bjf | jussi, i explained this to AlanBell | 16:12 |
| apw | bot, so ... we just continue to do the same and we are bot agnostic | 16:12 |
| jussi | strange. I find it most helpful. | 16:12 |
| apw | do you push many tables through it ? | 16:12 |
| jussi | No... | 16:13 |
| jussi | I guess IRC team meetings are very different to kernel meetings ;) | 16:13 |
| bjf | jussi, the bot grabs the topic changes but then just adds the raw irc log at the end, i don't find that usefull | 16:13 |
| jussi | bjf: As I said, Im sure bugs would be helpful - perhaps in the future we can create modes in it so theres a mode that puts the output to a style that works better for teams with this kind of meeting. | 16:17 |
| bjf | jussi, as i said, i discussed it with AlanBell, he didn't see it as bugs, i'm more than happy to keep doing what i'm doing | 16:17 |
| apw | often trying to make something do everything is a recipe for disaster | 16:19 |
| apw | bjf, does the new bot at least give us the beginning and end so we can find the poo to process mroe easily ? | 16:20 |
| bjf | apw, i just use the raw log, it's easy enough to find the beginning and end | 16:21 |
| bjf | apw, there is a startmeeting/endmeeting | 16:21 |
| apw | fair enough, was thinking if there was a url it gave you at the end and you could use that to process against that it might have value | 16:22 |
| bjf | apw, maybe, but i'd have to make changes to the script, and the next time they change the bot output i'd have to make more, and so on, and so on, ... | 16:23 |
| apw | fair enough | 16:23 |
| bjf | apw, the next person to run the meeting can decide if they want to do it differently | 16:24 |
| ogasawara | I doubt anyone is really reading our meeting minutes that closely to even care | 16:25 |
| bjf | jussi, "our way" is completely documented: https://wiki.ubuntu.com/KernelTeam/RunningTheIRCMeeting | 16:25 |
| bjf | ogasawara: that is very true | 16:26 |
| joaopinto | Hi | 16:29 |
| joaopinto | after apt-get sourcing the kernel where can I find the list of Ubuntu specific patches ? | 16:30 |
| jjohansen | apw: morning, so what I was pinging you about was CVE-2011-4081, it is marked as needed for hardy but at least on a first glance it looks like the code wasn't introduced until 2.6.32 | 16:30 |
| ubot2 | jjohansen: ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4081) | 16:30 |
| apw | ogasawara, that RunningTheIRCMeeting page doesn't seem to have the kteam-tools magic in it, perhaps you could slam it in when you work it out | 16:30 |
| ogasawara | apw: yep, will do | 16:31 |
| apw | joaopinto, the ubuntu specific patches are all directly applied in the version you get from apt-get source | 16:31 |
| joaopinto | ah ok :\ | 16:31 |
| jjohansen | have you managed to fully script the meeting now :) | 16:31 |
| apw | joaopinto, if you want the raw patches they are in the our public git trees | 16:31 |
| apw | joaopinto, every upload has a corresponding tag in those repositories to allow you to find the exact source | 16:32 |
| joaopinto | I have checked the source, just wanted to be sure the patch was not applied somehow during the build process | 16:32 |
| apw | other than on hardy there are no patches applied at build time | 16:32 |
| apw | jjohansen, you should be able to mark hardy 'not-affected' then and my bot will trust you | 16:33 |
| apw | jjohansen, in theory if the other end was working changing it to Invalid in the bug would be sufficient | 16:33 |
| joaopinto | there is no patch included for bug 843431 yet :\ | 16:33 |
| ubot2 | Launchpad bug 843431 in linux "Logitech camera microphone does not work / makes "chipmunk" sound" [Medium,Triaged] https://launchpad.net/bugs/843431 | 16:33 |
| apw | jjohansen, propogating to UCT as not-affected and triggering my ignoreing it | 16:33 |
| apw | joaopinto, is it marked Fix Released ? | 16:34 |
| joaopinto | no, actually there are many bugs related to this issue, with different status and progresses | 16:34 |
| jjohansen | apw: okay, so just fix it in uct, or do I need to mark invalid in the bug too | 16:34 |
| apw | joaopinto, indeed from the bug it is not clear that anyone has a fix for it even | 16:34 |

| joaopinto | well, someone is applying patches for it :) | 16:35 |
| joaopinto | I have one affected webcam, whose device id is not listed on that specific patch, I am testing it now | 16:36 |
| bjf | joaopinto, it helps to know which version you are talking about | 16:37 |
| joaopinto | bjf, version for ? | 16:37 |
| apw | joaopinto, ok that patch seem to have _just_ hit mainline in v3.2-rc1 | 16:37 |
| bjf | joaopinto, also, we get most of these cinds of patches from upstream stable releases | 16:37 |
| joaopinto | yeah, was checking http://www.spinics.net/lists/stable-commits/msg13878.html | 16:37 |
| apw | joaopinto, and it is marked for stable so we should see it for older releases soon enough via there | 16:38 |
| bjf | joaopinto, kernel version or hardy/lucid/maverick/natty/oneiric | 16:38 |
| joaopinto | I don't remember when the problem was introduced, it's present on oneiric | 16:38 |
| bjf | joaopinto, that's all i wanted to know, what kernel you were trying to build (didn't see it in the scroll back) | 16:39 |
| apw | joaopinto, ok added the useful bits of that to the bottom of the bug | 16:40 |
| joaopinto | apw, where can I check the v3.2-rc1 quirk patch ? (want to to check for my device id) | 16:40 |
| apw | it is 2394d67e446bf616a0885167d5f0d397bdacfdfc in linus' tree | 16:41 |
| apw | joaopinto, ok that patch is sitting in gregs queue for 3.0 and 3.1 | 16:42 |
| apw | so we should get it in oneiric in the next weeks | 16:43 |
| joaopinto | ok, QuickCam E 3500 not there, I am going to test for a few more days to be sure that it fixed, once I am sure, how should I proceed to ask for a device id to be added to the list ? | 16:43 |
| apw | the most direct way is to send a patch up to mainline and mark it for stable handling | 16:43 |
| joaopinto | (the issue is random, I can't reliably determine that the fix is working) | 16:43 |
| apw | if that too scarey you can send a patch to the ubuntu kernel list and we can help | 16:44 |
| joaopinto | well, I am an end-user, whatever is easier for me :) | 16:44 |
| joaopinto | I will email the ubuntu kernel list with the bug report link | 16:45 |
| AlanBell | bjf: if it doesn't work for a team then that is a bug | 16:45 |
| joaopinto | tks for your time | 16:46 |

| undriedsea | Hey Everyone, | 21:48 |
| undriedsea | I am having a problem accessing /proc/<pid>/mem range after mprotect has made it readable. It almost seems the procfs driver is not aware of the updated permissions. Any ideas or hints would be great! | 21:48 |
| undriedsea | 1. Process A ptrace ATTACHs to process B | 21:48 |
| undriedsea | 2. Process A cannot access of a given range in process Bs /proc/<pid>/mem due to the associated mapping in /proc/<pid>/maps being non-readable | 21:48 |
| undriedsea | 3. Process A requests process B use mprotect to mark given mapping as readable (mprotect returns success) | 21:48 |
| undriedsea | 4. Process A now should be able to read the range in /proc/<pid>/mem but can only read part of the range... | 21:48 |
| undriedsea | Details: http://codepad.org/DMItNdYa | 21:48 |

| Kano | there are lots of pple with that hardware out there | 23:42 |
| Sarvatt | does it fall back to swiotlb gracefully? | 23:42 |
| Sarvatt | if not you can boot with intel_iommu=off to work around it | 23:43 |
