| hrw | hi | 07:55 |
| hrw | is ubuntu kernel tree git bisectable? | 07:55 |
| hrw | cause with 3.0.0-10 my router fans are on 4500rpm instead of <2000rpm like it was on 3.0-1 | 07:56 |
| diwic | hrw, https://wiki.ubuntu.com/Kernel/KernelBisection - or flirt with apw to make test kernels for you ;-) | 08:06 |
| jjohansen | hrw: yes and no | 08:08 |
| hrw | will read | 08:08 |
| jjohansen | hrw: it is bisectable from the import point forward, otherwise you need to bisect against upstream with the ubuntu patches thrown on top | 08:08 |
| hrw | jjohansen: in other words: ubuntu kernel tree is rebased often? | 08:09 |
| smb | During development: yes | 08:10 |
| jjohansen | hrw: yes its rebased up until the kernel freeze (5 days ago) | 08:10 |
| hrw | ok, will stay then with 3.1.0-rc6 self built instead probably | 08:12 |
| hrw | or will bisect upstream clean kernel | 08:13 |
| smb | Not, sure, are there probably 3.0.x mainline builds as well to compare against? | 08:14 |
| hrw | I am fine with bisecting on my own | 08:16 |
| smb | Sure, I find them still useful for narrowing the range for bisection quickly | 08:19 |
| hrw | right - http://kernel.ubuntu.com/~kernel-ppa/mainline/ exists ;D | 08:23 |
| hrw | will have to connect monitor/keyboard to machine for grub selection | 08:24 |

| hrw | hi again | 09:21 |
| hrw | 3.0.4 mainline == 1917rpm fan. 3.0.4 ubuntu = 4500 rpm | 09:21 |
| apw | hrw, an interesting result indeed | 09:22 |
| hrw | d510mo board (atom d510) | 09:22 |
| apw | hrw and is there any cpu load when running ubuntu kernel? | 09:23 |
| hrw | apw: load <1.0 | 09:23 |
| apw | comparible to mainline ? | 09:23 |
| hrw | apw: same load - routing packets + irssi session | 09:24 |
| apw | and the reported load is comparible | 09:24 |
| hrw | yes | 09:24 |
| apw | clearly the machine is doing more, else it wouldn't be so very hot | 09:24 |
| hrw | it had 4500rpm 23°C | 09:24 |
| apw | as we can assume the environmental load is the same | 09:24 |
| hrw | now it has 2000rpm 46°C which is also fine | 09:24 |
| apw | i'd be interested in comparing powertop output on both | 09:26 |
| apw | looking at wakeups and also looking at c-state residency and frequency state residency | 09:26 |
| hrw | 1.13/oneiric will be fine? | 09:27 |
| apw | if there is nothing obvious then a bisect through the the ubuntu delta will be the next logical step | 09:27 |
| apw | 1.13 has most of what you want yes | 09:27 |
| smb | D510 has no power management afaik but the wakeups per second might be interesting | 09:28 |
| hrw | Wakeups-from-idle per second : 191,1 interval: 15,0s | 09:29 |
| hrw | Top causes for wakeups: 31,0% (204,1) [ath9k] <interrupt> | 09:29 |
| hrw | this is router/accesspoint | 09:29 |
| apw | its is the comparison from one to the other that is interesting so collect them all on both | 09:30 |
| smb | hows that comparing between mainline and the ubuntu kernel | 09:30 |
| hrw | I will reboot to ubuntu and collect 'powertop -d' output | 09:30 |
| hrw | brb | 09:30 |

| hrw | hi | 09:47 |
| hrw | 3.0.0-11-server and also 1757rpm 49°C | 09:47 |
| hrw | http://krzys.juszkiewicz.com.pl/~hrw/powertop/ has powertop dumps | 09:48 |
| apw | hrw, so which kernel was bad ? | 09:59 |
| hrw | 3.0.0-8 probably | 10:03 |
| hrw | if you have it somewhere (amd64 -server) then I can check | 10:03 |
| apw | hrw if its working fine and in line with mainline in the -11 kernel then i think we are all happy | 10:05 |
| apw | hrw, though 3.0.0-8.11 was based on 3.0.1 mainline not 3.0.4 ? | 10:06 |
| apw | https://launchpad.net/ubuntu/oneiric/+source/linux/3.0.0-8.11 | 10:10 |
| apw | hrw, you can get old binaries from the launchpad librarian for example as above | 10:10 |
| hrw | I am fine with just leaving it as it is ;) | 10:17 |

| apw | smb, do any of your machines have real serial ports on them ? | 14:22 |
| smb | apw, sure | 14:22 |
| apw | smb, that you use as consoles ? | 14:23 |
| smb | apw, not directly. I may do. but normally use sol | 14:23 |
| apw | smb, sol appears as a serial console to the kernel anyhow doesn't it ? | 14:24 |
| smb | apw, correct. on the server its just a serial port | 14:24 |
| smb | to linux | 14:25 |
| smb | apw, So as long as it is not the real hw part of the cable connection my server is already using the serial console for boot | 14:27 |

| tgardner | apw, kernel.org is resolving again. maybe some of the git repos will begin to reappear | 15:02 |
| apw | tgardner, looks the same to me, all 'down for maint' and git.k.o is non-existant | 15:03 |
| tgardner | apw, uh, yep. was just coming to the same conclusion | 15:03 |
| BenC | tgardner: Does oneiric's udev require a minimum kernel level? | 15:21 |
| tgardner | BenC, not to my knowledge, though I've been more concerned with backporting recent kernels to Lucid. | 15:21 |
| BenC | udevd[1162]: unable to receive ctrl connection: Function not implemented | 15:22 |
| BenC | I get flooded with that if I run oneiric's udev on a 2.6.34 kernel, but backing udev down to natty's version makes it all happy | 15:22 |
| tgardner | BenC, hmm, I haven't the faintest idea. | 15:23 |
| BenC | Ok, thanks | 15:23 |
| BenC | tgardner: - Some architectures might need a later kernel, that supports accept4(), or need to backport the accept4() syscall wiring in the kernel. | 15:29 |
| BenC | tgardner: usage of accept4() is the cause | 15:29 |
| BenC | just in case you ever hear about it again | 15:30 |
| tgardner | BenC, ok. the only arches that I care about for LTS backports (so far) are x86'en | 15:30 |
| BenC | I wasn't suggesting you backport anything, just trying to track it down :) | 15:31 |
| tgardner | BenC, understood. | 15:31 |

| smb | bjf, You may already know (I wasn't around last week) but the meeting-bot now seems to want the name of the meeting as an argument to startmeeting | 16:50 |
| bjf | smb, the bot can screw itself | 16:58 |
| smb | bjf, Won't mind. Just thought I relate to you how the other meeting succeded in convincing it to do something | 16:59 |

| smb | Hm, seems to work as good without. Only difference is that the topic is screwed more or less. *shrug* | 17:02 |
| herton | ppisati: can you rebase git://kernel.ubuntu.com/ppisati/ubuntu-maverick.git ti-omap4? it got two more patches today, doesn't pull clean | 17:07 |
| ppisati | herton: ok, i'll do | 17:10 |
| tgardner | apw, we're using overlayfs for oneiric live CDs now, right ? | 17:14 |
| ppisati | herton: don | 17:16 |

| gnomefreak | since *xorg.conf no longer exists how to i drop back to default ati drivers? removeing fglrx doesnt help | 19:14 |
| gnomefreak | i was told kernel takes over and sets drivers since that file no longer exists | 19:15 |
| apw | gnomefreak, that is normally the plan, check for radeon being blacklisted in /etc/modprobe.d | 19:18 |
| apw | though are you sure there isn't an xorg.conf selecting fgrlx when installed, i thought there was | 19:18 |
| gnomefreak | apw: i cant find it in /etc/X11 | 19:19 |
| apw | gnomefreak, worth asking on #ubuntu-x, they should know | 19:20 |
| gnomefreak | there is a fglrx.conf in /etc/modeprobe.d | 19:21 |
| chrisccoulson | is it normal for modprobe to take this long on startup - https://launchpadlibrarian.net/80443468/farnsworth-oneiric-20110920-9.png? | 19:22 |
| chrisccoulson | seb128 doesn't see the same issue on his laptop, and we have quite similar hardware - http://people.canonical.com/~seb128/seb-e6410-oneiric-20110920-9.png | 19:22 |
| gnomefreak | apw: thanks ill ask them when i get back. thanks you for the help | 19:23 |
