| zabyl | I understand that this link is not for kernel bugs am I right? | 07:16 |
| zabyl | thank you, filed it bug #776141 can you see it? | 07:26 |
| ubot2 | Launchpad bug 776141 in linux "kernel bug in 11.04 server x64 btrfs" [Undecided,New] https://launchpad.net/bugs/776141 | 07:26 |
| RAOF | jjohansen: Because they'd prefer you use “ubuntu-bug linux”, which'll include all sorts of interesting information automatically :) | 07:33 |
| RAOF | zabyl: That's not a particularly good bug report. Specifically, it doesn't actually say what went wrong, with what kernel version, or at what point. Including some description (like “the kernel panics with <msg> on boot”) and the full error message/kernel panic is likely to make it better. | 07:35 |
| zabyl | do you know how to redirect / log kernel trace to some file in /boot | 07:37 |
| zabyl | links provided in this bug report are from the console output and pointing to exact location in the source inode.c and extend-tree.c of the 11.04 build | 07:39 |
| RAOF | Right. But don't contain the *actual error message* | 07:46 |
| RAOF | Taking a photograph of the screen seems to be a reasonably common method of capturing early-boot panics. If the system mounts the drives - it's not at all clear from your bug report whether this is the case or not - then you'll find a full, unabridged log in /var/log. | 07:47 |
| apw | zabyl, i can only seconf RAOF's comment, the bit that is missing is the stack trace of how we got to that line | 07:53 |
| zabyl | Yes the system did not mount / and because CONFIG_BUG=y in /boot/config-2.6.38-8-server I was able to see the output of BUG_ON for these lines | 07:57 |

| nags_ | I am looking for some info on support for dual-Xeon (each 4 core) server grade machine on ubuntu | 11:35 |
| nags_ | can someone help me on this? | 11:35 |
| _ruben | nags_: should just work | 11:43 |
| nags_ | _ruben, how do I confirm this? | 11:44 |
| nags_ | _ruben, working is one part....but I am more interested to know if this can make use of the full potential of the HW | 11:45 |
| nags_ | _ruben, because we are spending good amount of money on buying the server | 11:45 |
| nags_ | _ruben, and we are going to use it for our development (Linux and Android build server) | 11:45 |
| _ruben | nags_: the latter would completely depend on the software you run on it | 11:45 |
| _ruben | if configured properly, a build server would use all those 8 cores just fine | 11:46 |
| _ruben | you'll likely need to tell the build scripts/tools/etc to use 'em though | 11:46 |
| _ruben | like make -j 8 | 11:46 |
| nags_ | _ruben, sorry, if this is a dumb question...but when you say configure, do you mean re-compilation of ubuntu? | 11:47 |
| nags_ | _ruben, ok...got it | 11:47 |
| _ruben | no, ubuntu itself handles it just fine, it's the applications you want to use all cores which need to be told to do so | 11:47 |
| nags_ | _ruben, we always use -j, but inherently is ubutntu using all the cores? | 11:47 |
| nags_ | _ruben, the main problem today is the time it takes to build our Kernel and Android file system | 11:48 |
| nags_ | _ruben, so I have asked for a good server.... | 11:48 |
| nags_ | _ruben, at the same time want to make sure that the new server will solve my problem. | 11:48 |
| _ruben | kernel builds highly benefit from multiple cores and scales to dual quad-core just fine | 11:48 |
| nags_ | _ruben, ok...thanks | 11:52 |
| nags_ | _ruben, is there a official source from where I can get this info? I need to give this proof to the management to get the approval for a server. Hope you understand. | 11:52 |
| _ruben | smp support in the kernel has been there for ages, which is the most important part of it all | 11:59 |
| fairuz | indeed.. I tried once with -j4 and -j27..it's a big big big difference | 12:15 |
| fairuz | in term of compilation time | 12:15 |
| nags_ | fairuz, it might be obvious...but can you elaborate on what you saw with j4 and j27? Sorry, if this is a dumb question. | 12:31 |
| fairuz | nags_: I might say the output of compiled files is faster on j27.. which is normal because you have 27 files been compiled at once | 12:34 |
| nags_ | fairuz, thanks. But, I believe it has only 8 cores (in the case of quad xeon) and I would expect only -j8 to make a difference and anything more than j8 behave the same? | 12:35 |
| _ruben | i'd say the disk subsystem plays a fairly important role as well here, so either shove a ton of ram in it to cache a lot, or use really fast disks (ssds or it you want blazing fast: fusion-io) | 12:42 |
| fairuz | nags_: yea i think if you only has 8 cores, anything more than j8 will behave the same | 12:43 |
| fairuz | (afaik) | 12:44 |
| === michaelh1|away is now known as michaelh1 | ||
| _ruben | that's assuming each job would max out a core, which doesn't have have to be the case, so -j x, with x > 8 could be even faster .. takes a bit of experimenting to find the optimal number | 12:57 |
| _ruben | some jobs might be disk intensive and hardly touch the cpu | 12:57 |
| Kano | hi, will todays daily kernel build for 32 bit or not | 13:06 |
| _ruben | dunno, crystal ball is broken | 13:07 |
| Kano | for oss driver testing it would be really usefull | 13:09 |

| tgardner | JFo, possibly. I'm still trying to figure out who owns the package | 16:26 |

| tgardner | JFo, alright, this is the staging driver brcm80211 in 2.6.38, not the binary blob. I'm not seeing any stable updates, but it might not hurt to have him try -preproposed. | 16:29 |

| Sarvatt | hallyn: I just saw https://wiki.ubuntu.com/SergeHallyn_ppakernels -- great guide! one thing though, you can pass -i -I to debuild instead of moving .git out of the way to ignore it in the build package | 16:40 |
| hallyn | Sarvatt: that's awesome, thanks. I'll add that to the page. | 16:46 |
| hallyn | Sarvatt: I ahven't done it yet, but I keep expecting to forget to move .git back :) | 16:46 |
| tgardner | Sarvatt, something like dpkg-buildpackage -S -rfakeroot -I.bzr -I.git -I.gitignore -i"\.git.*" | 16:46 |
| Sarvatt | -i -I removes all vcs files, no need to specify specific types anymore | 16:46 |
| tgardner | Sarvatt, its backwards compatible to Hardy environments | 16:47 |
| Sarvatt | ahh gotcha | 16:47 |
| hallyn | tgardner: meaning '-i -I' will not work on hardy? | 16:49 |
| tgardner | hallyn, I'd have to back and read the man page again to remember why. this has evolved a bit over 4 years | 16:49 |
| JFo | tgardner, preproposed solved him it seems | 16:50 |
| hallyn | tgardner: thanks | 16:51 |
| tgardner | JFo, whoa, that was fast | 16:51 |
| JFo | yeah, he enabled, tested and got back to me | 16:51 |
| bjf | JFo, enabled how? that kind of implies "proposed" to me | 16:53 |
| JFo | well, enabled/grabbed the driver | 16:53 |
| JFo | sorry for confusion | 16:53 |
| JFo | as he didn't 'enable' anything | 16:54 |
| bjf | JFo, ah, do we know what exactly he did? did he download and install the pre-proposed kernel? | 16:54 |
| JFo | one sec... | 16:54 |
| bjf | JFo, that would tell me that the fix is in the upstream stable commits which are on the master-next branch of natty and not what is currently in -proposed | 16:55 |
| tgardner | bjf, which is why I suggested pre-proposed. there are a pile of stable updates in the queue | 16:56 |
| JFo | ok, I'll get clarification | 16:56 |
| bjf | tgardner, ack, i'd just like to know which batch it was in, what's on master-next isn't going to hit -proposed for 3 weeks | 16:56 |
| tgardner | bjf, might be this one: mac80211: initialize sta->last_rx in sta_info_alloc | 16:57 |
| tgardner | thats what the bitching in his log was about | 16:57 |
| bjf | tgardner, i wish we had our shit more together, such that we could quickly take that and turn it into a quick script that could look for the same issue in bugs and suggest the same action | 17:01 |
| JFo | tgardner, looks like it did not solve him in-fact. | 17:01 |
| bjf | tgardner, but we'll get there | 17:01 |
| bjf | dang | 17:01 |
| JFo | bjf, it was the pre-proposed kernel | 17:01 |
| JFo | he says it is diminished but still happens | 17:01 |
| bjf | JFo, good to know, that was the right one for him to try | 17:01 |
| JFo | so he is looking at http://ubuntuforums.org/showpost.php?p=10729117&postcount=135 | 17:02 |

| JFo | heh | 17:02 |
| tgardner | JFo, oh, I forgot about the firmware update | 17:03 |
