h00kIf I am trying to load a module on boot by adding it to /etc/modules (netconsole, troubleshooting a panic on 12.04), and it fails to load, is that an issue with that module or with the kernel?03:40
h00kHowever, if I load it manually (sudo modprobe netconsole), it ignores the /etc/modprobe.d/netconsole options I have, so I'd have to load all options with the 'sudo modprobe netconsole...etc' line.03:41
h00kI don't know enough to know whether it's with the kernel itself, or with the module :(03:44
infinityh00k: Try /etc/modprobe.d/netconsole.conf05:04
infinityh00k: If I recall, modprobe ignores certain filenames.05:04
infinityh00k: (It might tell you that with -v)05:04

cooloneyw/o '-a' it won't start ceph09:19
ckingcooloney, hrm, thats unexpected09:20

henrixsmb: from your last comment in bug #999755 i see you were not able to reproduce it in oneiric09:48
ubot2Launchpad bug 999755 in linux "Kernel crash in rb_next doing ohai loops" [Undecided,In progress] https://launchpad.net/bugs/99975509:48
henrixsmb: i spend some time trying to trigger it (both in VM and bare metal), without any luck09:48
smbhenrix, correct, still running without a crash09:48
henrixsmb: ok09:49
smbhenrix, What I'd probably do is to upgrade the kernel and make sure it runs as long with the new one09:49
henrixsmb: ack09:50
henrixbut what if we fail to reproduce it? would you be comfortable to tag it as verified (as the patch has been accepted upstreams already)? or would you rather revert it on oneiric?09:51
=== ricotz_ is now known as ricotz
smbhenrix, As I tried to say in the bug comment. For Oneiric go on and accept it verified. For natty, stop worrying ...09:52
henrixsmb: yep, that's what i understood from your comment. just wanted to make sure :)09:53
henrixsmb: thanks Stefan09:53
smb:)09:53
smbapw, There would be the question for Quantal. There will not be a crash but (probably a very theoretical) race. I am not sure about it ever make it into a stable later than 3.2 for that reason. Should we still bother to get it in there or just move on and pretend we did not see anything (which is actually true)09:58
apwsmb, thats a tricky one without knowing the nature of the race.  i will trust you :)10:26
smbapw, Actually its even tricky when knowing it. But I believe the worst case is that a task is moved over and placed into the wrong run queue for some time. I guess we can live with that every now and then (which may be as often as any leap seconds). 10:30

ppisaticool, i received an ssd for my desktop: is there a way to install P on it without requiring to boot an entire box with it attached?14:00
ppisatie.g. can i attach it to my running desktop, launch an "installer", select the ssd and let it install P on it?14:00
smbppisati, Use kvm? 14:02
ppisatismb: uhm... qemu is an option indeed14:03
ppisatismb: but axctually the install is an application that runs on top of a live system14:04
ppisatismb: so i guess it's doable even on my desktop without any system emulation14:04
smbppisati, Maybe. Though I thought you were asking about a simple solution. :)14:05
ppisatidoh!14:05
ppisatiubiquity requires all the qt libs!14:06
ppisatiand even some kde packages...14:06
ppisatikille me, now...14:06
ppisatiok, qemu...14:06
apwppisati, can't you debootstrap the disk ?14:07
ppisatiapw: i wonder if there're some particular steps (like /etc files&c) that are handled only via the installer14:07
ppisatibut yes, deboostrap is another option14:08
apwi'd just attach it to a test box and install on it as a usb disk14:08
apwthen switch it in when its done14:08

rtghack it into /etc/rc.local ?14:24
ppisatirtg: never used Linaro images, but i guess rc.local is an option14:24

ppisatirtg: playing with the guru plug?14:27
smbSounds a bit dodgy...14:28
ogra_rtg, pointing /etc/network/interfaces to dhcp doesnt work ?14:32
rtgppisati, no, still the sabrelite stuff14:32
ogra_oh, nano ... thats likely special since tons of stuff get hacked out of the system to make it small14:32
rtgogra_, ah, tahts likely it. doh!14:32
ogra_so it might or might not work the usual way14:32
ogra_but /e/n/i would be my first thing to try14:33
rtgogra_, it should. the nano image comes with the ISC client installed14:33
ogra_yeah, then it should14:33

ckingbit stupid of me, especially 'cos I tested it on Natty to make sure it worked OK16:10

infinitycking: (re: 871891)16:17
ckinginfinity, yep, if you could try that kernel out, I'd appreciate it, I'm not sure if one of those testers has a sane set-up16:20

infinitycking: I did indeed file the original bug, yes.  Though, I think it's suffered bug bloat since, as someone else said that nohpet didn't work for them (and it does for me).16:26
infinitycking: Which, I assume, means two different S10-3s, internally, and two different bugs.16:26
brendandjsalisbury, how would i load samsung-firmware?16:26
brendandsorry, samsung-laptop16:26
ckinginfinity, does the kernel I provided w/o the nohpet work?16:26
infinitycking: I'll spin it up in a bit over here and let you know.16:27
ckingok, no rush16:27
infinitycking: Well, I'll be scientific and make sure that the current precise still sucks too.  I haven't run without the cmdline option since I filed the bug. :P16:27
* cking notes infinity has an Atari logo on his LP page. perhaps cking should put the commodore chickenhead on his16:28
infinitycking: See, I used to own a lot more C= hardware than Atari, but I went with the less ugly logo. :P16:29
infinitycking: (I used to run a lot of both, mind you, when I was deeply involved in 68k porting)16:29
ckinginfinity, yep, I had a C64 and Atari 1040ST16:30
brendandjsalisbury, modprobe -l samsung-laptop shows something underneath kernel/drivers/platform/x8616:30

brendandjsalisbury, it's listed in /proc/modules. does that means it's loaded?16:42

brendandjsalisbury, let's do this in the bug. put a comment asking me to test precise16:47
jsalisburybrendand, will do16:49
smoserok. its that time again.16:52
smosersmoser's noob questions16:52
smoseri'm just curious. if i kexec from one kernel to another, does memory get zero'd ?16:52
smoseri know that in the kdump use case it clearly does not, but kdump explicitly has the second kernel only "knowing" about a small portion of the memory.16:53
infinitycking: So... I can't tell you if your fix fixes anything, because current precise (-27-) seems to work fine without nohpet.16:54
ckinginfinity, 'current' as in the one I gave you to test?16:55
infinitycking: No, you gave me a -29-16:57
infinitycking: I'm saying that I'm testing the -27- from updates, and it's fine.16:57
infinitycking: (Like I said, I haven't booted without nohpet since oneiric, so this could have magically been fixed ages ago)16:57
ckinginfinity, OK, well thanks for testing, this info makes it just a little more mysterious16:58
infinitycking: Okay, switching from unity-2d to 3d, on resume with the old kernel, my root window didn't get painted, so I couldn't log in.17:05
infinitycking: But that could have just been a random bug.17:05
infinitycking: (Rebooting into your test kernel, I didn't have that issue, though)17:05
infinitycking: Okay, just reproduced the root window painting bug with your kernel too, so that's unrelated, and probably just unity being crap.17:11
ckinginfinity, surely not!17:11
infinitycking: So, conclusion is that (for my hardware), your kernel changed nothing.17:11
ckinginfinity, OK - thanks for testing17:11
infinityThe upshot is that my hardware seems to have been fixed somewhere between 3.0 and 3.2.whatever. :P17:11
ckinglooks like another random S3 bug to me17:12
* ppisati -> gym17:12
infinitycking: I'd just close the bug, if it wasn't for the metooing on it.17:13
* cking nods, well I will look at that other users bug and see what's busted and maybe then ask them to file a new bug17:14
* infinity nods.17:18
infinityAnother 10 resume cycles on the old kernel, and I'm satisfied this all works correctly now.17:19
infinitySo, I dunno what fixed it, or when, but thanks? :P17:19
