| hypatia | hey folks, i'm trying to track down an acpi regression from maverick to natty. i'm a bit clueless with the ubuntu kernel tree - if i clone the natty repo, will it have all the older maverick stuff too? | 02:39 |
| twb | The upgrade from 2.6.32-31 to -32 (lucid, x86-64) broke my LXC subsystem. Containers didn't start at all; IIRC lxc-start(8) failed to mkdir in /var/cgroups (which was mounted). | 02:57 |
| twb | Before I wade through all the LP notes in the changelog.Debian, anybody know offhand what's going on? | 02:58 |
| twb | Unfortunately I can't give you exact details because the machine in question is mission-critical and I already failed back over to -31 when the issue occured on Sunday. | 02:58 |
| sconklin | twb: first I've heard of it but I would very much like for you to file a bug if you can. Especially if you can do it from a machine with the same hardware running that particular kernel | 03:01 |
| twb | Looks like you disabling CONFIG_NET_NS completely breaks containers with different network ranges. So, uh, good job. | 03:01 |
| sconklin | Not exactly the way in which we like to overachieve | 03:02 |
| twb | And it was done to fix a bloody FTPd. I hate FTP (http://mywiki.wooledge.org/FtpMustDie). | 03:03 |
| sconklin | twb: if you file bugs (and please do), then please also add the tag "regression-updates" | 03:03 |
| twb | OK, I'm doing that now | 03:05 |
| twb | What is the package name to report against? | 03:06 |
| sconklin | thinking | 03:06 |
| sconklin | file against linux (the kernel) Even if that's wrong it'll get the logs we need. | 03:08 |
| sconklin | and post the bug number(s) here. I'll check back a little later, I'm in the middle of cooking dinner . . . | 03:08 |
| twb | Will do | 03:08 |
| twb | Am I allowed to set "importance critical" ? | 03:18 |
| twb | Too late, I did | 03:20 |
| twb | When malone emails me back, I'll cite the bug number | 03:22 |
| twb | It hasn't emailed me yet :-/// | 03:42 |
| RAOF | You haven't set the “don't email me for stuff that I do” switch, have you? :) | 03:43 |
| twb | AFAIK I haven't touched that setting | 03:43 |
| twb | I have used the lp web UI long enough to tell it my GPG key, so I can use email like the Goddess intended | 03:43 |

| lamont | why does the kernel hate this VM so? | 03:55 |
| twb | lamont: is the VM using md RAID? | 03:56 |
| lamont | why yes, yes it is | 03:56 |
| lamont | more to the point, halp how make better? | 03:56 |
| twb | I have no idea. I am so sick of grub that I use syslinux for my (md RAID1 /boot, md RAID5 LVM root) systems now. | 03:57 |
| twb | Last time I used grub2 it didn't support auto-detecting (grub-probe) anything inside the md RAID segment at all, and I had to manually tell it which modules to compile into the MBR. But that was around 2007. | 03:58 |
| twb | There is also a #grub which might help | 03:59 |
| lamont | cool | 03:59 |
| lamont | thanks | 03:59 |

| sconklin | twb: sweet, Cascading failures | 04:05 |
| twb | I was going to tell you about an even better one, but I've repressed it and can't remember | 04:06 |
| sconklin | twb: I have to knock off so I can be all fresh and rested and ready to play whack-a-mole with regressions tomorrow. please subscribe me to the bugs when you get them created, or email me the numbers. Or ping me tomorrow during the day central time. | 04:14 |
| twb | What's your email address? | 04:14 |
| twb | Thanks, I'll email you if I can't subscribe you directly. | 04:15 |
| twb | Good night. | 04:15 |
| sconklin | twb: in PM (although it's not a secret) | 04:15 |
| sconklin | I actually probably signed that kernel that failed | 04:15 |
| hypatia | sconklin: before you go, could you look up at my git question? | 04:16 |
| sconklin | looking | 04:16 |
| hypatia | thanks :D | 04:16 |
| sconklin | hypatia: Hi! | 04:16 |
| hypatia | hiya! | 04:17 |
| sconklin | so - good question | 04:17 |
| sconklin | No | 04:17 |
| hypatia | i've been bugging poor matt garrett about this for 2 weeks | 04:17 |
| hypatia | and finally pinned it on a kernel regression | 04:17 |
| hypatia | by which i mean "works in maverick, not natty" | 04:18 |
| sconklin | We start each new series from whatever the upstream kernel is at the beginning of the cycle. So while it will have a lot of the same history, Maverick (in this case) will have had selective patches applied for fixes and from upstream stable, and so will differ from the new upstream | 04:18 |
| sconklin | do you have an idea which file or subsystem it's in? | 04:19 |
| sconklin | (I'm asking so I can steer you to the right git usage) | 04:19 |
| hypatia | sconklin: it only boots with acpi=off | 04:19 |
| hypatia | that's about all i've got :/ | 04:20 |
| sconklin | oh, that's pretty generic | 04:20 |
| hypatia | hp laptop, insyde bios | 04:20 |
| hypatia | same deal with hdd or ssd | 04:20 |
| hypatia | 10.10 x86 and 64bit both boot fine with acpi on | 04:20 |
| ohsix | url? | 04:20 |
| sconklin | I hate to do this to both you and Colin, but cking is absolutely the most knowledgeable person on our team about this sort of thing | 04:21 |
| hypatia | ohsix: for the laptop? | 04:21 |
| ohsix | for whatever report on it, i've got some stuff with insyde around | 04:21 |
| sconklin | and Colin has been working on a firmware test suite that smokes out a lot of BIOS issues | 04:21 |
| hypatia | sconklin: no skin off my back, i'm happy to learn something new and help out if i can :) | 04:21 |
| hypatia | ohsix: i'll ping you when i file an issue on it tomorrow | 04:22 |
| hypatia | must do CS homework tonight, was just hoping to get some kernels building :) | 04:22 |
| sconklin | hypatia: there's also a lot of interesting info on Colin's blog | 04:23 |
| ohsix | have you done any bios updates recently? even if you haven't tried resetting the bios options to the default (fine if you make your changes over after that) | 04:23 |
| sconklin | http://smackerelofopinion.blogspot.com/ | 04:23 |
| ohsix | it's fixed the weirdest stuff on mine; theres a binary option block that can be changed by all sorts of things you can't actually see with the bios setup, but the reset will still reset them all | 04:24 |
| sconklin | ok, g'night, gotta fall over now. | 04:24 |
| hypatia | ohsix: i am running the latest bios which is from jan 2011... but it's been modded to remove the pci-e whitelist for wifi cards | 04:24 |
| hypatia | stupid hp consumer crap | 04:24 |
| hypatia | ohsix: i'll give the resetting thing a try | 04:24 |
| ohsix | you might start looking there since it's modified | 04:24 |
| * hypatia nods | 04:24 | |
| hypatia | i can try reloading the old bios too, i have it somewhere | 04:25 |
| ohsix | i don't like those whitelists either; but they do it for testing w/the fcc from what i understand | 04:25 |
| hypatia | yeah, i kinda think it's bull - like how broadcom etc. used to refuse to make Free drivers on the grounds that they would be modifiable and thus allow the user to get around fcc approvals | 04:27 |
| twb | sconklin: #796993 | 04:27 |
| hypatia | </rant> | 04:27 |
| ohsix | broadcom is kind of special; they have a lot of customers and it's all proprietary stuff, any part of the drivers being opened for some products can compromise their market position too | 04:29 |
| hypatia | and then my laptop died, because i have no acpi and i forgot i was unplugged | 04:33 |
| hypatia | ;_; | 04:33 |
| hypatia | ^^ motivation | 04:33 |
| cdbs | Does the latest Oneiric kernel work well with the nvidia driver? It seems to not build when it encounters the version number 3.0.0 | 04:59 |
| ohsix | the version change is still percolating through just about everything that touched the kernel | 05:01 |
| ohsix | aside from that i don't know :] | 05:01 |
| cdbs | ohsix: so it should work well? It failed to build when I tried using the kernel from the mainline ppa 2 weeks ago | 05:02 |
| ohsix | couldn't say; i don't use it, its probable that there are things other than the version number that are keeping it from being built, binary drivers are like that | 05:03 |
| * cdbs takes a ball of garbage and throws it on the nVidia banner hanging on the neighbour's house | 05:05 | |
| twb | cdbs: ahaha, third-party FTL | 05:08 |
| ohsix | you could try the nouveau driver :] | 05:08 |
| twb | It's a pity Intel moved their GPUs from the motherboard to the CPU, because now I can't buy high-end servers with intel GPUs | 05:08 |
| twb | (The on-CPU GPU is only available on low-end CPUs) | 05:08 |
| cdbs | ohsix: Nouveau doesn't work with a new GPU released last month :@ | 05:10 |
| cdbs | the disadvantage of buying stuff that's too new | 05:10 |
| cdbs | ohsix: btw, it built with the new kernel | 05:14 |
| cdbs | in dkms, of course | 05:14 |
| cdbs | but that's maybe because I'm using xorg-edgers? | 05:14 |
| ohsix | maybe, it tends to get updates for new stuff pretty quick | 05:15 |
| twb | ITYM the disadvantage of buying hw from a FOSS-hostile vendor | 05:24 |

| brendand | bjf - okay | 13:31 |
| hypatia | hey folks, any advice on doing a bisect between maverick and natty kernels? i have them both checked out | 14:00 |
| hypatia | the bug was introduced somewhere after Linux butler 2.6.37-020637rc2-generic #201011160905 SMP Tue Nov 16 09:08:47 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux | 14:00 |
| apw | hypatia, if the problem is exposed in the mainline builds as well i would use those to narrow it down | 14:46 |
| hypatia | i'm bisecting from Ubuntu-2.6.36-0.1 | 14:48 |
| hypatia | compiling right now, woot | 14:48 |
| * hypatia hasn't built a kernel in a dog's age | 14:48 | |
| apw | brendand, if you find any could you add kernel-3.0 as a tag please, so we can monitor them | 14:49 |
| brendand | apw - will do | 14:50 |
| apw | hypatia, all the uploads we ever did are available in the launchpad librarian | 14:50 |
| sconklin | hypatia: the reason apw is suggesting that is because the mainline builds have a more linear history, and are easier to bisect, or at least to narrow it down to two adjacent versions. | 14:52 |
| apw | and because the all exist in one place | 14:52 |

| db260179 | jjohansen: Thanks for the reply. What is causing the issue? | 17:50 |
| jjohansen | db260179: if we knew that for sure it we be fixed | 17:50 |

| apw | tseliot, and pray it only wants to exclude itself | 17:56 |

| apw | tseliot, there is nothing, its gone | 17:57 |
| apw | eveyrthing was converted to driver specific mutexes | 17:57 |
| tseliot | apw: oh, so are you suggesting that I point that to an empty function? | 17:58 |
| apw | tseliot, no make a new 'global' mutext called 'ati_lock' and make lock/unlock_kernel take and release it and hope its enough | 17:58 |

| jjohansen | tseliot: right, but there may be some other lock, or small set of locks that will | 18:03 |
| tseliot | jjohansen: from a quick search I've noticed that other drivers are simply using mutex_unlock() | 18:04 |

| jjohansen | tseliot: I'm not surprised it works at some level, its whether it has some odd failures when interacting with the console, suspend, etc, that are worrisome | 19:14 |
| jjohansen | tseliot: none the less, its good to hear you are having success | 19:14 |
| tseliot | jjohansen: yes, but it should be better than having no working driver at all (when there's no alternative) in oneiric | 19:15 |
| jjohansen | tseliot: indeed :) | 19:15 |
| tseliot | hopefully AMD will work on a proper fix soon | 19:15 |
| jjohansen | yeah | 19:15 |

| chadhogg | following advice from diwic, I've spent all day bisecting the ubuntu-natty kernel to debug 793437, and feel that I have accomplished extremely little | 23:48 |
| chadhogg | (the last 6 revisions that I have tried all failed to build, for a variety of reasons) | 23:48 |
| chadhogg | what is the likelihood that continuing with this is just a waste of my time? | 23:48 |
