[00:54] <colinmarc> Hi, I'm getting a complete system crash whenever mdadm tries to recover or create a raid array. When I try in recovery mode there is a call trace, but it is missing from the logs
[00:57] <colinmarc> any ideas?
[00:59] <jk-> colinmarc: do you get the call trace reported in the 'dmesg' output ?
[01:01] <colinmarc> I'm not sure
[01:01] <colinmarc> it doesn't say, and it's not present in any of hte logs
[01:01] <colinmarc> the*
[01:02] <colinmarc> btw... I'm running 9.04 x64 (I'm not in the wrong room am I?)
[01:02] <jk-> colinmarc: no, this chan is the right one.
[01:03] <jk-> just run 'dmesg', it'll dump the contents of the kernel log
[01:03] <colinmarc> I just reproduced the error, it reads like [    65.XXXXXX] [<ffffxxxxxxx>] etc
[01:03] <colinmarc> well it doesn't let me type or enter anything once the error happens
[01:03] <jk-> ah.
[01:03] <jk-> can you get a photo of the screen?
[01:04] <mase_wk_> colinmarc: can you enable serial output on the machine ?
[01:04] <colinmarc> hmm... let me try. It might be a minute
[01:04] <colinmarc> for the picture. what do you mean, serial output?
[01:05] <jk-> colinmarc: serial cable connection to another computer
[01:05] <mase_wk_> the kernel will be able to output its logging via serial
[01:05] <mase_wk_> you can connect to it with minicom or by cat /dev/ttyx
[01:06] <mase_wk_> though i would suggest minicom
[01:06] <colinmarc> hm. I imagine I would need my desktop for that and it's a windows machine and also disassembled right now. Also I don't know if I have the correct cables or anything
[01:07] <colinmarc> but I'm taking a picture...
[01:07] <mase_wk_> i'm having some problems building a kernel package on 8.04 which will automatically run update-initramfs. I am passing the --initrd flag to make-kpkg
[01:07] <mase_wk_> is there something else I need to do ?
[01:07] <mase_wk_> colinmarc: ok
[01:09] <colinmarc> alright, I've got a picture. Can I send it through irc?
[01:10] <jk-> colinmarc: maybe file a bug, and attach the screenshot?
[01:10] <colinmarc> erm
[01:11] <mase_wk_> I've also tried setting the environment variable but that doesn't seem to make it either.
[01:11] <colinmarc> let me put it up on imageshack
[01:13] <colinmarc> http://img41.imageshack.us/img41/7349/img4876o.jpg that's the entire screen
[01:13] <colinmarc> no cursor at the bottom or anything
[01:13] <colinmarc> okay, not the entire screen, but almost
[01:13] <colinmarc> it's a projector which is why there's no border or anything
[01:14] <jk-> colinmarc: can you scroll up at all? (chift+pgup?)
[01:14] <colinmarc> nope
[01:24] <colinmarc> I thought it might be a sata controller bug, but it's just intel ICH7 as far as I know and it's switched to AHCI
[01:30] <jk-> apw / ogasawara: https://bugs.launchpad.net/ubuntu/+bug/394371 looks fixed?
[01:30] <ubot3> Malone bug 394371 in linux "boot failure after 2.6.31 kernel upgrade" [High,Incomplete] 
[01:33] <ogasawara> jk-: indeed, I'll get it cleaned up
[01:36] <colinmarc> so, am I out of luck?
[01:37] <jk-> colinmarc: i think a serial console would help us a lot here
[01:37] <jk-> other options are to try a more recent kernel; what are you using at the moment?
[01:38] <colinmarc> the latest 9.04
[01:38] <colinmarc> err, I'd check btu I'm currently fscking
[01:38] <colinmarc> whichever is on the download page right now
[01:38] <jk-> sure, ok
[01:44] <colinmarc> 2.6.28
[01:53] <DanaG> oh yeah, so the go7007 in upstream seems to be broken.
[01:53] <DanaG> build fail: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32-rc1/BUILD.LOG
[01:55] <DanaG> Might be good to disable it.
[02:03] <mase_wk_> is there a mailing list for the ubuntu kernel ?
[02:04] <DanaG> yeah, I think there is one somewhere.  I just prefer to use either IRC or gmane.
[02:06] <mase_wk_> yeh i normally like irc but i'm having some issues that no one seems to know the answer to so i thought i'd post to the list rather 
[02:08] <DanaG> I think the wiki thing in /topic has a link to the mailing list.
[02:08] <mase_wk_> your right , found it thanks

[07:32] <micahg> would an ipod not mounting be a kernel bug?
[07:39] <amitk_> micahg: that would depend on what dmesg is saying.
[07:41] <micahg> I have bug 434295
[07:41] <ubot3> Malone bug 434295 in ubuntu "Ipod won't mount in 9.04" [Undecided,New] https://launchpad.net/bugs/434295
[07:52] <amitk_> micahg: that bug doesn't have much information. Could you run 'apport-collect -p linux 434295' ?
[07:53] <amitk_> micahg: or actually 'apport-collect -p linux-image-`uname -r` 434295'
[07:53] <amitk_> More info here -> https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies
[07:54] <micahg> amitk_: sorry, it's not my bug, I was attempting to move it to the proper package
[07:54] <micahg> I can post the request in the bug though
[07:56] <amitk_> micahg: that bug doesn't have any info to help fix the bug except that ipod mount doesn't work. And the fact that the ipod shows up as storage and then disappears seems to indicate something else..
[08:00] <micahg> amitk_: ok, I'll leave it for someone else with broader knowledge to figure out then
[08:01] <amitk_> micahg: it is a good idea for him to run that command though, to collect the necessary info
[08:03] <micahg> Thanks, I'll add it to the bug report.

[09:53] <amitk_> apw: Can we update the firmware for the rt2870 from http://www.ralinktech.com.tw/support.php?s=2 ? There is a potentially newer version of firmware in the RT3070USB(RT307x) driver on the page (newer date, larger file size)
[09:53] <amitk_> apw: how can I tell if the firmware doesn't regress the older cards?
[09:54] <smb> amitk_, I am not sure he can hear you
[09:54] <amitk_> smb: he went deaf?
[09:55] <smb> amitk_, Not exactly just on vacation
[09:55] <amitk_> smb: ohh. All week?
[09:55] <smb> No, supposed to be back tomorrow
[09:55] <amitk_> ack
[09:56] <smb> amitk_, But my feeling would be that firmware update might regress older cards. Depends on how the driver decides to pull it in.
[09:56] <smb> Some load different firmware versions for different hw
[09:57] <amitk_> smb: the file name is the same. But the "newer" one is shipped with a different driver with a newer date.
[09:58] <smb> amitk_, That feels a bit risky. But that is just a guess

[14:28] <ericm> do that have any relationship with apic?

[19:12] <smoser> hey all,
[19:13] <smoser> the acpiphp.ko module is required for hotplug support in kvm guests (bug 364916)
[19:13] <ubot3> Malone bug 364916 in linux "When running Ubuntu as an Eucalyptus VM instance, module acpiphp is not available to be loaded, complicating the use EBS volume" [Wishlist,Fix released] https://launchpad.net/bugs/364916
[19:13] <smoser> is there a way that this module could be automatically loaded? 
[19:14] <rtg> smoser, I think you'll have to insmod it via initramfs
[19:14] <smoser> note, i'm not interested in /etc/modules or /etc/initramfs-tools/modules, but rather in the module being magically loaded when necessary across the board (similar to how I vaguely understood that e1000.ko is loaded)
[19:15] <smoser> that make sense ?
[19:16] <smoser> we definitely *can* modify our initramfs for uec and/or our vmbuilder output images. but a broader solution would be for that module to automatically load when running on "hardware" that supported it
[19:17] <rtg> smoser, there doesn't seem to be anything in the driver that will trigger loading
[19:17] <rtg> smoser, I think I could build it into the kernel.
[19:20] <smoser> rtg, what would you think about that ? is that something reasonable ?
[19:21] <rtg> smoser, yes, its quite reasonable for the ec2 kernel. I'm just trying to figure out how acpiphp gets built at all.
[19:21] <smoser> not relavant for ec2. only for uec (-virtual: -generic-pae or -server)
[19:22] <rtg> smoser, oh, that explains it. I'll have to look a bit closer at the server. dunno if I can build it in for sure.
[19:22] <smoser> ec2 does this via some other xenish hotplug mechanism (i'm not quite sure). acpiphp is how kvm does it
[19:26] <rtg> smoser, I think you're gonna have to go the initramfs route.
[19:27] <smoser> i accept your answer, but just curious, why not build in?
[19:31] <rtg> smoser, regression potential for existing platforms. its kind of a major hunk of code to impose at this late date.
[19:31] <smoser> fair enough

[20:59] <rysiek|pl> hi guys
[20:59] <rysiek|pl> any living souls around?
[21:00] <rysiek|pl> anybody heard about -ck's BFS?
[21:00]  * rysiek|pl teases. probably everybody here has heard about that
[21:00] <rtg> rysiek|pl, I've read Ingo's responses.
[21:00] <rysiek|pl> rtg: to the new -ck's scheduler? where?
[21:01] <rtg> LKML
[21:01] <rtg> there was quite a flurry a couple of weeks ago when Colin initially announced it.
[21:02] <rysiek|pl> rtg: care to sum-up in a sentence? I'd rather not digging through LKML
[21:02] <rtg> it ain't ready for prime time.
[21:02] <ali1234> cyanogenmod for g1 uses bfs
[21:02] <ali1234> i think that's the only place real users are using it yet
[21:03] <rysiek|pl> rtg: that we all know. question is: a). is there a chance guys at kernel.org will ever consider pluggable schedulers; b). are there any other reasons (besides code maturity and doesnt-scale-to-4096-cores) not to use it?
[21:04] <rtg> rysiek|pl, frankly, you'll have to ask Ingo et al those questions.
[21:04] <rysiek|pl> rtg: ok, thanks; thought you might had that covered ;)
[21:04] <rtg> I've zero exposure to it
[21:04]  * rysiek|pl 's gotta test the bugger
[21:05] <rysiek|pl> I suppose this question had to come up here already, but what the hey
[21:06] <rysiek|pl> any chances on including -ck/BFS in ubuntu? as a testing kernel maybe?
[21:06] <rtg> rysiek|pl, pretty unlikely unless it gets into staging or something.
[21:07] <rysiek|pl> mhm
[21:07] <rysiek|pl> and any other scheduler, for that matter?
[21:07] <rtg> rysiek|pl, same criteria
[21:09] <rysiek|pl> right
[21:09] <rysiek|pl> thanks
[21:12] <ali1234> rysiek|pl: i live in hope that someone will make a ppa for it
[21:12] <ali1234> actually there's already a ppa but no packages in it yet
[21:13] <rysiek|pl> interesting
[21:14] <rysiek|pl> gotta look into that
[21:14] <rysiek|pl> ali1234: maybe you know how hard/time consuming is setting-up a ppa?
[21:15] <ali1234> no, i've no idea, sorry. i know how time consuming a kernel bisect is though :/
