| LLStarks | hi, how do i build my own kernel ppa? | 08:15 |
|---|---|---|
| dileks | hi | 10:34 |
| dileks | LLStarks: https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel | 10:35 |
| dileks | BTW, see topic :-) | 10:35 |
| LLStarks | dileks, if i want to ppa really exotic and bleeding edge code without a debian folder, am i screwed? | 11:17 |
| LLStarks | cuz i suck at packaging | 11:17 |
| dileks | LLStarks: whats your goal? | 11:23 |
| LLStarks | dileks, drm-next is packaged, but i want to package airlie's drm-dmabuf2 tree | 11:24 |
| LLStarks | i can build the debs, but i have to clue how to translate that to a ppa | 11:25 |
| dileks | dunno if all patches from ubuntu apply then | 11:25 |
| LLStarks | it's a vanilla kernel | 11:25 |
| LLStarks | plus his upstream work | 11:26 |
| dileks | I am building with 'make deb-pkg' | 11:26 |
| dileks | its fine for (fast) testing from any kernel GIT tree | 11:26 |
| LLStarks | not make-kpkg? | 11:27 |
| dileks | build_linux-with-deb-pkg.sh: http://paste.ubuntu.com/981526/ | 11:27 |
| dileks | dunno if make-kpkg still works, it was never my 1st choice | 11:28 |
| LLStarks | concurrency 1- | 11:29 |
| LLStarks | *10 | 11:29 |
| LLStarks | isn't that excessive even on a quadcore with ht? | 11:30 |
| LLStarks | gonna pass out while this builds | 11:30 |
| dileks | a wise man gave me that empirical formula (longterm experiences): max_make_jobs = core(s) x2 +1 | 11:31 |
| LLStarks | is that assuming threads>cores? | 11:32 |
| dileks | you can reduce make-jobs-no of course | 11:32 |
| dileks | even on pentium-m =5 was OK | 11:32 |
| LLStarks | either way, j8 takes at least 20 minutes to build a full ubuntu kernel and this is a 2630qm | 11:33 |
| LLStarks | too afraid to strip stuff | 11:33 |
| dileks | BTW... | 11:33 |
| dileks | http://nopaste.snit.ch/139833 | 11:34 |
| dileks | if you dont need... CONFIG_DEBUG_INFO=n | 11:35 |
| LLStarks | thx | 11:35 |
| LLStarks | sleep time | 11:35 |
| dileks | it gets huge | 11:35 |
| dileks | not only deb-files | 11:35 |
| dileks | your local build-dir explodes to some GiB | 11:35 |
| dileks | IIRC there is one debug-info-reduce kernel-config. dunno how much space this saves and whats with "all" debug-symbols | 11:36 |
| dileks | CONFIG_DEBUG_INFO_REDUCED | 11:37 |

| JanCeuleers | Guys, I would like to highlight the RAID corruption bug introduced in upstream commit c744a65c1e2d59acc54333ce8 and fixed by commit 30b8aa9172dfeaac6d77897c67ee9f9fc574cdbb | 18:17 |
| JanCeuleers | The md subsystem maintainer (Neil Brown) observes today on the linux-raid mailing list that Ubuntu appears to be more susceptible to this problem than other distros | 18:18 |
| JanCeuleers | Would it be possible to expedite deployment of the fix? | 18:18 |
| JanCeuleers | The problem causes RAID metadata to be damaged upon shutdown, so that the array can't be reassembled after reboot | 18:18 |
| === smb` is now known as smb | ||
| sforshee | JanCeuleers, the fix is already in the kernel in precise-proposed, so it will be in the next update | 19:42 |
| === panda is now known as Guest86272 | ||
| JanCeuleers | That's great, thank you. | 19:53 |
| JanCeuleers | Just want to mention that the longer it takes for the fix to become official, the more people will get stung by this. | 19:53 |

| luc4_mac | Hi! I'm experiencing network shutdowns when system is inactive. Anyone who knows if this is something known? | 23:16 |
| dileks | looked into logs? | 23:16 |
| luc4_mac | dileks: yes, I posted those in a bugreport, I couldn't see anything strange. The fact is that I just reproduced the problem now in an hour and I noticed it is sufficient that the kernel recognizes a plugged mouse to restore the network. | 23:18 |
| luc4_mac | bugreport is 997767 | 23:18 |
| luc4_mac | I didn't think it was kernel-related, but now I'm starting to think it might | 23:19 |
| luc4_mac | only think I see in dmesg is the mouse plugged in | 23:19 |
| dileks | [68627.945751] TCP: Possible SYN flooding on port 6882. Sending cookies. Check SNMP counters. | 23:21 |
| luc4_mac | dileks: yes, I have it now as well. | 23:21 |
| luc4_mac | do you think it may be related? | 23:21 |
| dileks | dunno | 23:23 |
| dileks | you tried static-IP setup instead of dhcp? | 23:23 |
| luc4_mac | dileks: you mean stopping the dhcp server? | 23:24 |
| dileks | for static-IP you dont need a dhcp-server | 23:25 |
| luc4_mac | dileks: yes, but this box also has a dhcp server that I don't think I'm using anymore. Do you mean I have to try to stop the server or that I have to configure the ethernet interface to not use the real dhcp server? | 23:27 |
| dileks | dont start services you dont need | 23:29 |
| luc4_mac | dileks: it is a temporary situation… anyway ok, I can try to stop that and to configure static assignment | 23:29 |
| luc4_mac | Oh… I see from dmesg that isc-dhcp-server terminated incorrectly many times. | 23:31 |
| dileks | yupp, thats why I asked you to try static-IP | 23:33 |
| luc4_mac | 6882 is related to torrent i see… maybe I should also stop anything related to that... | 23:34 |
| luc4_mac | dileks: I didn't mention anyway that without X/KDE I couldn't reproduce the problem | 23:41 |
| dileks | doesnt kde has a nm-frontend (nm-service)? | 23:43 |
| luc4_mac | yes | 23:43 |
| luc4_mac | I mean that I simply shutdown X and KDE and the connection stayed up for the entire day. | 23:44 |
| dileks | sounds like wake-on-lan is activated in your bios | 23:49 |
| luc4_mac | possible. Why? | 23:50 |
| dileks | if you say shutdown computer | 23:52 |
| luc4_mac | sorry, maybe I explained myself the wrong way. I shutdown the X server. I remained in the terminal without X running. | 23:53 |
| dileks | inspect with netstat | 23:55 |
| luc4_mac | what exactly? This problem has started with 12.04. Never had this problem before. This desktop stays up 24h. | 23:56 |
| dileks | open ports/connections | 23:57 |
| dileks | network* | 23:57 |
| luc4_mac | At the moment I have less than 20 connections. The problem is that when the problem occurs I cannot debug. Pluggin a mouse in the port is sufficient to start the network and solve the issue. | 23:59 |
