[00:01] smb: just fyi, bug 776936 has me worried bc it seems random, i have no idea of the cause, and we don't much test on i386... [00:02] Launchpad bug 776936 in qemu-kvm "Running KVM guest causes kernel panic on host" [Critical,New] https://launchpad.net/bugs/776936 [00:56] hallyn: ugh, that is not good [01:19] jjohansen: yup. i'll get a simple setup to reproduce in the morning, but i won't have his host storage or network setup. so we'll see just how easy it is to trigger [01:28] hallyn: easy to reproduce would be good, I'll see if can't get to poking at it tonight/tomorrow [01:58] jjohansen: cool, thanks much [03:02] can someone explain to me why /sys/bus/usb makes no sense? lsusb shows my keyboard is bus 2, device 3, but /sys/bus/usb/devices has nothing starting with a 2 and having a 3 in it... how are you supposed to find that node? [03:07] psusi: lsusb is giving the kernel representation, while /sys/bus/usb is the bus representation [03:07] If you unplug and replug you'll typically get a different device number [03:08] mjg59, why have two representations? how are you supposed to find the sysfs node for a given device, like the keyboard, so you can enable it to wake the system? [03:09] If you're looking for the keyboard then start from the keyboard, not from USB [03:10] and if you get a different device number, wouldn't it move to a new sysfs node? [03:10] No, because the toplogy is the same [03:11] Walk /sys/class/input, find keyboard, go to the USB node from there [03:11] I'm confused... device number = bus number and an ordinal assigned as devices are detected, no? [03:11] Yes, which is completely unimportant when it comes to the bus topology [03:11] A physical port always has the same number [03:12] The only time you actually care about that port number is when you're using a USB debug cable, because only one port per controller can drive one [03:12] Otherwise, the relationship is uninteresting [03:12] ohh... wait... so lsusb gives an ordinal assigned in order of detection relative to a bus, but /sys/bus/usb/devices lists them by hub-port? [03:12] Oh, I guess that's not strictly true. You might care for multihead as well. [03:12] Yes [03:13] I've no idea why lsusb behaves the way it does. It's really not useful. [03:13] I was just going to say that [03:13] But thankfully it's generally not something that you have to care about, because you're more interested in the device and not its usb path [03:14] (And you can get from device -> USB) [03:14] there isn't a good way ( i.e. user friendly command or gui utility ) to enable devices to wake is there? I was going to explain to this guy how to go flip on the wakeup setting in the sysfs node then ran into trouble with locating the usb stuff since I don't see anything in class/input other than events for buttons [03:15] No, there's nothing at present [03:15] didn't think so... [03:16] If you know it's usb then you can go /sys/bus/usb/drivers/usbhid/whatever/lala/power/wake [03:17] yea... was just doing that... but got 3 usbhid devices now... remind me to kick lsusb for using a useless nomenclature [05:40] I would like to ask questions about bug 662288 ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/662288 ).

[08:46] cking: I can still accesses them through the wiki [08:46] cking: https://launchpad.net/ubuntu/+spec/other-kernel-o-misc [08:46] not sure if that has been renamed or not [08:46] jjohansen, thanks - they now seem to have an other- prefix [08:47] ah [08:47] * cking tweaks his URLs [08:47] this happens every time, I sort out a list and then the names change [08:51] grrr, "Hide talks that aren't for me" *still* does not work [09:09] cking: has it ever worked? I know every time I have tried it at uds something has gone wrong [09:11] jjohansen, I'm just hacking a bash script to get the ical data and format it into some plain text that tells me where I should be :-) [09:11] hehe, nice [09:14] cking: http://arstechnica.com/business/news/2011/05/intel-re-invents-the-microchip.ars [09:14] cking: that is a fairly nice explanation of the trigate transitor [09:15] I was trying to imagine what they were describing from other articles - so thanks - that does have some useful images to show what's going on [09:17] nice explanation of the physics too [09:28] morning.

[14:49] soren: thanks, i'll take a look [15:27] I have a laptop that I installed afresh with Natty. I'm getting stuff like this: [ 3963.082105] EXT4-fs error (device sda5): htree_dirblock_to_tree:586: inode #14162517: block 56631703: comm update-mime-dat: bad entry in directory: rec_len is smaller than minimal - offset=0(4096), inode=4227858432, rec_len=0, name_len=0 [15:29] Does this sound familiar at all? [15:30] does not ring a bell for me at least... [15:31] It did exhibit from odd behaviour yesterday. apt crashing rather randomly, and reinstalling apt fixed it. That does suggest some sort of either filesystem, harddrive or memory error. [15:32] Erk.. fsck is *not* happy. [15:32] Yeah, unfortunately all of it might be possible. John, just had a case of odd behavior that turned out to be his ssd going away [15:33] This is a branch new laptop. Old-school hdd. [15:33] s/branch/brand/ [15:33] I actually saw that I had mistyped "brand" as "branch", deleted it, and wrote it again. [15:33] heh [15:34] at least consistent [15:34] \o/ [15:35] found something? [15:37] * ppisati starts packing stuff... [15:41] * JFo is so tired of packing [15:42] * smb is mostly done with it [15:42] same here, just painful this time. I am bringing a bunch of stuff that I would normally not have to [15:44] smb: No, just happy about being consistent. [15:44] That can be stressful. Well, somehow it feels a bit like it went too smoothly. Either I forgot half of it, or I just get more relaxed [15:45] soren, Ah. :) So I guess I would start with memcheck... (though this had been not so successful with the supermicro boards I tried it recently) [15:46] smb: Just finished that. No problems at all. [15:46] hmm ok. [15:46] smb: To be honest, I didn't let it finish. [15:47] Well, wasn't the default to never finish? [15:47] smb: ...but it had run a bunch of its tests across all the memory, and the odd behaviour this box was exhibiting was rather consistent, so I sort of assumed it would fail pretty quickly if that was really the problem. [15:47] smb: Right, yes, but I didn't let it run its entire test suite. That takes hours. [15:48] yeah I know. :) [15:48] smb: I'll restart it and let i finish overnight or something. === yofel_ is now known as yofel [15:50] soren, Yeah, other posiible way would be to use a usb drive for a test installation. That would probably give you a hint whether its somewher rather memory or controller/hdd [15:51] smb: Good idea. [15:52] smb: Dreadful timing, though. It's my wife's new laptop and I'm heading to UDS on Sunday. I doubt I'll have it production ready by then. [15:53] I would *hate* to have to wait for a week before I could get to use my new laptop. [15:53] soren, Those things know and resist... [15:54] It's taken me years to convince her to upgrade her laptop and now this. Darn it. [15:54] Years! [15:54] * smb hopes it is not a Toshiba... [15:55] Its as bad as saying po...bo... ;-P [15:56] It's a Thinkpad. That's how we roll in this house :) [15:56] X120e. It's a nice little box. [16:00] * sforshee goes to finish packing [16:37] ok, I am off to head to a few errands on the way to the airport. see you guys there. [16:38] Safe trip [16:38] same to you smb :-) [16:38] Ta :) [16:54] soren: i just ordered an x120e for my wife. it should be here on the 11th. [17:11] * smb wraps up. see who is there at uds === jj-afk is now known as jjohansen [17:54] smb, seeya at UDS [17:55] * cking considers packing too [18:19] Hi, I'm trying to generate info for a bug report on my tablet pc. When I (un)plug the power cable, the kernel panics. I've been following the guide at https://wiki.ubuntu.com/Kernel/Netconsole however when I try to modprobe netconsole, I get "FATAL: Error inserting netconsole (/lib/modules/2.6.38-8-generic/kernel/drivers/net/netconsole.ko): Unknown error 524" [18:20] Anyone wanna help me with that so I can get a bug report up? :) [18:47] Azelphur: never seen that before, anyhting more in dmesg? [18:48] jjohansen: [ 2407.111082] netconsole: eth0 doesn't support polling, aborting. [18:48] :( [18:49] Azelphur: :( indeed [18:49] my wifi is the same [18:49] so no usb to ethernet, no wifi, that rules netconsole out I guess? [18:51] hi, I've compiled the git kernel 2.6.38-9.43 for Lucid. [18:51] Should I upgrade the linux-libc-dev package to ensure conformity with the kernel installed? [18:52] In case afirmative, how can I do this? [18:52] simonbcn: shouldn't be needed, the kernel tries very hard to keep the abi stable [18:55] jjohansen, but this package is directly relationed with the kernel source, no? [18:55] and it's used to compile other programs, no? [18:56] Does this cause problems when compiling other programs? [18:56] (Sorry for my bad english) [18:56] simonbcn: not exactly, it pulls from some kernel headers but what it uses is stable [18:56] simonbcn: nope, no problems [18:57] generally it just doesn't use new features that have been exported by the kernel [18:57] ok, then it's right if I have the linux-libc-dev from Ubuntu Lucid (2.6.32) but I use the kernel 2.6.38, [18:57] yep [18:57] ok, thanks. [18:57] Other doubt, this is about compilation parameters [18:58] oh, I forgot to ask: How do you generate the package linux-libc-dev in git kernel? [19:01] Another doubt: I compile the kernel with: "AUTOBUILD=1 NOEXTRAS=1 no_dumpfile=true skipabi=true skipmodule=true do_doc_package=false full_build=false do_tools=false fakeroot debian/rules binary-indep" [19:01] but it generates the doc and tools package. What is the utility the "do_doc_package" and "do_tools" then? [19:13] jjohansen happen to know any other ways of getting the kernel panic copied out? [19:14] Azelphur: usb serial console [19:14] maybe crash kernel but I haven't had luck with that [19:14] hmm [20:35] ayan: It's a very impressive piece of machinery.
