| * apw is not finding it acceptable that pluging in an external screen now causes unity to crash | 07:33 | |
| smb | apw, Must be a scary screen | 07:33 |
| apw | this is a natty regression | 07:34 |
| RAOF | As in: a regression in natty, or a regression from natty? That said, I find unity in Oneiric is exactly as terrible at handling multiple monitors as in Natty :/ | 07:53 |
| ppisati | back in 10mins... | 07:53 |
| apw | RAOF, as in i believe it used to work in natty ... or its better with hdmi than vga not sure yet | 08:02 |
| * RAOF finds it hard to believe unity's monitor hotplug has got *worse* from natty. | 08:04 | |
| apw | RAOF, no it has gotten worse in natty in my experience | 08:04 |
| cking | progress... but not in the right direction | 08:04 |
| RAOF | Once it's sufficiently broken it'll look fixed? | 08:05 |
| apw | RAOF, i had to reboot with the monitor attached to have a hope of logging in without unity crashing in a heap | 08:05 |
| RAOF | Oh, yeah. Who doesn't? | 08:06 |
| * cking has to walk downstairs *again*, working from the loft conversion is getting me super fit | 08:06 | |
| * smb thinks they are in danger of "when it is sufficiently broken, nobody cares whether it gets fixed". Because all use something else | 08:06 | |

| amitk | smb: they stopped? any particular reason? | 08:13 |
| smb | amitk, Thought they had. But don't know of a specific reason. Maybe just got bored. | 08:14 |
| smb | amitk, Not hearing much of you lately. How are you? | 08:17 |
| amitk | smb: i know :-/ Been a busy summer so far. Too many thing happening in the PM working group in Linaro keeping me busy. Plus some home renovations.. | 08:19 |
| amitk | smb: how was Dublin? | 08:19 |
| smb | amitk, Yeah, there usually is no lack of something to do. The usual hive of bees (though no mankini incidents). Surprisingly I seem to have succeeded in looking at the things I planned to (which does not always happen). | 08:22 |
| smb | Must be because the moved out all those noisy HWE guys to a different room. ;-P | 08:23 |
| amitk | smb: same hotel? | 08:23 |
| smb | amitk, Yep, which I had no memories any more about the lack of AC in the rooms. Which we could have used this time | 08:24 |
| amitk | smb: hehe. They must've posted guards to avoid the mankini incidents :) | 08:25 |
| smb | Well, those probably would not have been as bad as before as there were no horse show people but Bon Jovi fans around. They are much less likely to worry about such a thing. :) | 08:26 |

| Tommeh | -rc6 maybe. | 10:35 |
| Tommeh | But 3.0.0 for radeon r600+ does give some nice performance increases in gnome-shell/unity | 10:36 |
| apw | yeah i am asking why he is running an out of date mainline kernel | 10:36 |
| jussi | apw: because I was told here to try it. (a couple of weeks ago). I thought the trace may be of use, so I posted the screenshot. If its useless, I will throw it away :) | 10:36 |
| apw | jussi, i would update to the latest and see if its still there, as thats quite early 3.0.0 | 10:37 |
| jussi | apw: ok. have we been building 3.0's for natty yet? or should I still be trying the oneiric builds? (as mentioned here before) | 10:38 |

| * apw looks | 11:23 | |
| smb | ppisati, I would guess it would be somewhere in rules.d. Either defining a version string wrongly in 0-* or using a wrong one in the binary rules... | 11:23 |
| apw | that + on the end is classicly added by the kernel itself when it is unsure of its own version number | 11:24 |
| apw | we normally override that in rules however | 11:24 |
| apw | LOCALVERSION= localver-extra= | 11:24 |
| apw | i have that on my kmake variable in debian/rules.d/0-* | 11:25 |
| apw | does your have that ? | 11:25 |

| ppisati | previous to your 3.0.0-rc6 push | 11:27 |
| ppisati | uhm no | 11:27 |
| apw | that might explain the error as you may be using the running kernel version in error then | 11:28 |
| apw | though note if you rebase to the latest tip the version number moved to 3.0.0 anyhow | 11:28 |
| apw | and the problem is removed | 11:28 |

| smb | vish, The real error is actually somewhere above that. The stamp file would just be created if the build went ok | 12:01 |
| vish | hmm, /me looks | 12:02 |
| apw | nigelr, if a simple patch like that fixes an obviously triggered oops then its possible to SRU it | 12:08 |
| apw | vish, the error would have been much before the end of the log as we build in parallel, search back for 'error' | 12:09 |

| smb | apw, Not sure, wasn't git bisect skip the thing probably needed if a certain revision just is not buildable but you would not want to say bad or good? | 12:14 |

| vish | smb: k, how do I fix it? | 12:16 |
| smb | Apparently there is no previous definition of kref_set | 12:16 |
| apw | vish if you cannot build a revision then saying git bisect skip will ask it to find another to test without taking this one as good or bad | 12:17 |
| smb | cauld be either a missing include or the patch that introduced it came in the wrong order | 12:17 |
| vish | apw: k, great! :) will probably have to do that, if i cant fix this.. | 12:18 |

| tgardner | lamont, its suspicious that both traces involve network functions. I think you also have the accursed r8169 ethernet driver. | 20:36 |
| lamont | I do | 20:36 |
| lamont | lsmod | grep 8169 | 20:37 |
| lamont | r8169 39714 0 | 20:37 |
| lamont | mii 5237 1 r8169 | 20:37 |
| tgardner | lamont, it has undergone serious renovation for 3.0.0, perhaps you could try the Oneiric kernel | 20:37 |
| lamont | I do have room and a spare network card that I could kill 8169 with fire and see if it makes any difference | 20:37 |
| lamont | or I could do that | 20:37 |
| lamont | how stable otherwise is oneiric's kernel? | 20:37 |
| tgardner | lamont, It seems to be doing pretty well. we're all using it on various platforms | 20:38 |
| tgardner | lamont, of course, knowing you, you'll have some bizarre HW that borks it right away | 20:38 |
| lamont | well... there is a vlan bridge on the box | 20:39 |
| lamont | Build needed 08:08:03, 1618388k disk space | 20:39 |
| lamont | I know that's a total lie, since I saw it up over 20GB of footprint sometime during that build | 20:39 |
| lamont | did we lose the patch that removed the intermediate build trees again? | 20:39 |
| lamont | (on a different note, that is) | 20:40 |
| tgardner | lamont, not that I know of. lemme check | 20:40 |
| tgardner | lamont, was this an oneiric build ? | 20:41 |
| lamont | dist-upgraded the machine to natty over the weekend | 20:43 |
| lamont | worked around the "3 crashes in 20 minutes" feature by tossing the maverick kernel on the box | 20:43 |
| tgardner | lamont, um, I was talking about the build space issue. | 20:43 |
| lamont | oh build-space | 20:44 |
| lamont | yeah | 20:44 |
| lamont | that was the 3.0.0-4.5 build | 20:44 |
| tgardner | lamont, the patch that removes intermediate files is still in the oneiric rules | 20:44 |
| dupondje | http://paste.ubuntu.com/642025/ => could this be a kernel bug or surely hw issue? | 20:44 |
| lamont | the machine in question had some old cruft in someones home directory that resulted in a disk space alarm that made me (1) boggle, (2) look at the build tree and boggle, and (3) clean out said homedir's cruft | 20:44 |
| lamont | tgardner: ok. I'll check into it more sometime, don't worry about it | 20:45 |
| lamont | at least not for a week or 3 | 20:45 |
| tgardner | lamont, ok, holler if it gets too annoying | 20:45 |
| lamont | well, it's more "if we release and it really is that big, it may well be that it doesn't build in a (virtualized) ppa". that would suck | 20:47 |
| tgardner | lamont, I'll have a closer look at it. every release accrues more modules, more drivers, more stuff | 20:48 |
| lamont | yeah | 20:49 |
| lamont | pretty soon, there could be a valid complaint of "bloat" | 20:49 |
| tgardner | herton, keep an eye on bug #809000. Its another lamont special. I'm suspecting the root cause is r8169 | 20:50 |

| herton | ok. lamont, isn't this on the same machine which had the NAT issue? | 20:51 |
| lamont | herton: no | 20:51 |
| jwi | tgardner: uh - bad time to ask about enabling some experimental drivers/configs? :) | 20:52 |
| lamont | it's a tower which hosts a kvm guest that lives on a different vlan than the primary IP of the box, while also having an IP on that subnet too, since it doesn't like to talk to the guest via the router | 20:52 |
| tgardner | jwi, as a matter of policy we generally do not enable drivers that are EXPERIMENTAL | 20:52 |
| jwi | right, but there's still a whole bunch of them enabled | 20:53 |
| tgardner | jwi, I acknowledge that there have been exceptions. I'm mostly not interested in supporting (or taking bugs for) experimental drivers and features. we've already gotten bit by network name spaces in 2.6.32 | 20:55 |
| jwi | RTL8192CU seems like a good candidate, considering its experimental rtlwifi siblings are enabled | 20:55 |
| tgardner | staging is different then experimental. | 20:56 |
| jwi | its not in staging | 20:56 |
| jwi | i saw the network name space issue, the ones i was thinking about really are "experimental or no device driver at all" cases | 20:58 |
| tgardner | jwi, shit, all the rtlwifi drivers are experimental. how;d they get enabled ? (I probably did it) | 20:59 |
| tgardner | hmm, we probably got them for free when they moved out of staging. | 21:00 |
| jwi | i don't think they ever have been in staging - rtlwifi is a new "project" | 21:01 |
| tgardner | jwi, the config option wasn't though. I think it got reused. | 21:02 |
| jwi | urgh, that might be true | 21:02 |
| tgardner | jwi, ok, committed 'UBUNTU: [Config] CONFIG_RTL8192CU=m' | 21:06 |
| tgardner | now, back to what I was doing... | 21:06 |

| Q-FUNK | howdy! is left_control+K mapped to some SysReq key on ubuntu? every time I press these, the CPU kills all power immediately without proper shutdown. it's annoying since control-K is "cut" in 'nano'. | 22:46 |
| charlie-tca | Q-FUNK: according to the shortcuts lists, it shouldn't be | 22:49 |
| charlie-tca | http://askubuntu.com/questions/28086/unity-keyboard-mouse-shortcuts/28087#28087 | 22:49 |
| Q-FUNK | I'm not using unity. | 22:49 |
| charlie-tca | http://www.techdrivein.com/2011/04/31-useful-ubuntu-1104-unity.html | 22:49 |
| Q-FUNK | and the issue also affects vcons operation. | 22:50 |
| charlie-tca | Still shouldn't be, without SysReq key also | 22:50 |
| Q-FUNK | hmm.. ok | 22:52 |
| Q-FUNK | another issue I have: on my ubuntu+1 host, kernel 3.0.0 makes the CPU overheat. it has become a significant issue that I've had to go back and run 2.6.38 instead. | 23:15 |
| Q-FUNK | is this a known feature of current 3.0 kernels? | 23:16 |
| jjohansen | Q-FUNK: In general the 3.0 kernel should be better than .38, a couple bugs have been found that fix some problems with the scheduler keeping the processor for entering into lower power states | 23:23 |
| jjohansen | Q-FUNK: you can try booting with pcie_aspm=force as a kernel parameter and see if that reduces your power problems, but I doubt it will as .38 should suffer from that problem as well | 23:25 |
| Q-FUNK | it's just that since .38 the whole casing is burning hot. I've kept an older kernel (.36 IIRC) and going back to that significantly reduces the temperature. | 23:26 |
| jjohansen | Q-FUNK: and no left-ctrl-K is not mapped to sysrq in Ubuntu | 23:26 |
| jjohansen | Q-FUNK: ah then pcie_aspm=force might just work for you | 23:27 |
| jjohansen | it was introduced in .38 | 23:27 |
| jjohansen | that is the problem, before linux was ignoring the bios which wasn't really correct, but some buggy bioses see significant power regressions because of the newer behavior | 23:28 |
| jjohansen | passing pcie_aspm=force restores the old pre .38 behavior for those systems | 23:29 |
| jjohansen | Q-FUNK: I am not sure what to say about your left ctrl-k behavior besides open a bug, it shouldn't be happening and doesn't happen for me | 23:30 |
| Q-FUNK | mind you, that red-hot host doesn't have any pcie bus | 23:31 |
| Q-FUNK | didn't I read somewhere that kernels since after 2.6.32 consume a heck of a lot more power and that it's a known issue, though? | 23:32 |
| jjohansen | Q-FUNK: I think you are thinking of the phoronix article | 23:33 |
| Q-FUNK | could be | 23:33 |
| jjohansen | his figures don't really back up some of his assertions about power usage | 23:33 |
| jjohansen | he did find a regression see the pcie_aspm=force from above | 23:33 |
| jjohansen | but as I said that is really more of a bios issue | 23:34 |
| jjohansen | there are other regressions, like the scheduler one I mentioned | 23:34 |
| Q-FUNK | afaik he was quoting some upstream developer as knowing that the increased power consumption was introduced some time back, but wasn't seen as such a priority issue | 23:34 |
| jjohansen | that should be fixed in the latest kernel | 23:34 |
| jjohansen | Q-FUNK: hrmm, there have been things that increased power consumption but where not major regressions | 23:37 |
| jjohansen | an hence were not high priority | 23:37 |
| Q-FUNK | well, considering that my +1 host is suddenly burning hot but never was before, I'd have to doubt that assumption | 23:38 |
| jjohansen | part of the problem with power is every machine is different so it is hard to test for regressions | 23:38 |
| jjohansen | that is it works for me and on my machines ... | 23:38 |
| jjohansen | Q-FUNK: not claiming you aren't seeing a major regression, just the general picture as seen by the kernel community | 23:39 |
| Q-FUNK | also, since recent kernels, 'dpkg' regularly manages to segfault. it doesn't occur if I boot into an older kernel. | 23:39 |
| Q-FUNK | ok, fair enough :) | 23:39 |
| jjohansen | Q-FUNK: that sounds like a processor overheating | 23:39 |
| Q-FUNK | yup | 23:40 |
| Q-FUNK | but again, doesn't happen if I reboot into ... was it 2.6.38 | 23:40 |
| jjohansen | Q-FUNK: well we can try bisecting the problem | 23:40 |
| Q-FUNK | 2.6.38-8-generic | 23:40 |
| jjohansen | but that is going to take installing more than a few kernels | 23:41 |
| Q-FUNK | it started happening sometimes during 2.6.39, but it was not too frequent. now, with 3.0.0, it's nearly at every update | 23:41 |
| Q-FUNK | ... at every 'apt-get upgrade' | 23:42 |
| jjohansen | Q-FUNK: the tighter the range you can provide the better. If you want me to bisect this, open a bug and subscribe me to it/point me to it | 23:42 |
| jjohansen | I can provide you kernels to test, I need to know a known good point and a known bad | 23:43 |
| Q-FUNK | jjohansen: that sounds good. I'm away from my +1 host this week, but I could return to the issue during the weekend and add you then. | 23:43 |
| jjohansen | Q-FUNK: okay, I'll keep an eye out for it | 23:44 |
| Q-FUNK | the control-k issue is on my natty laptop, though. I haven't seen if it affects my +1 host too or not. | 23:45 |
| jjohansen | that one is just bizarre, I've never heard of such a problem | 23:46 |
| Q-FUNK | well, it could also be triggering some model-specific key combination. this laptop is a dell, if it helps any. | 23:47 |
