rackerhackerjjohansen: fwiw, checking out from git fixed my problems 100% - thanks again01:27
jjohansenglad to hear it01:28
rackerhackeri don't even know if i should log a bug for the previous issues - i could reproduce it on a completely clean environment01:29
rackerhackerjjohansen: not sure if this is the appropriate forum to ask, but what's your outlook on xen support fully returning to vanilla kernels?02:12
zulrackerhacker: not soon maybe 3402:21
rackerhackeryeah, i'm not feeling optimistic :/02:22
rackerhackeri noticed the fedora devs mentioned in their docs that they were hoping for .3302:22

MTeck-LinuxI'm missing something in the kernel... In lucid when I try to mount anything it says 'mount: special device /dev/sda1 does not exist' that's my /boot. / is on sda2 and that mounts fine during boot. It's dying at mountall; any idea what's missing or screwed up?10:48
Q-FUNKsmb: can we apply your extra debug messages patch to something 2.6.32 so that we continue testing this Geode issue against Lucid material?11:49
Q-FUNKit also seems that plymouth cannot work against a 2.6.31 kernel, anyhow.11:50
apwMTeck-Linux, sounds like sda1 wasn't foudn by udev to me, check /var/log/udev and see if it has anything about sda112:14
smbQ-FUNK, I can't say anything about the plymouth issue. I can check how well the old patches go against Lucid. Do you want the amount of debug that still crashes or the amount that suddenly makes it work?12:51

maxbHi, running Lucid's kernel, I no longer have a /dev/net/tun. Does anyone know why that might be?13:17
maxbBooting Lucid with Karmic's kernel makes it appear again13:17
sorenmaxb: It's no longer automatically loaded.13:18
sorenmaxb: You can wait for a new kernel (which will have it built in), or you can "modprobe tun" until then.13:18
rtgmaxb, should be temporary. initramfs no longer creates the tun/tap device, but now the driver is gonna be built into the kernel.13:18
maxbWhat should users of, etc., openvpn clients be doing.... ah, right13:19
Q-FUNKsmb: the amount that makes it boot :)13:25
smbQ-FUNK, Ok, I try to make it happen. But it might get a bit delayed13:26
Q-FUNKsmb: sounds good.  thanks!14:09
tjaaltonI have a reproducible kernel crash on lucid14:16
tjaaltonhow do I get a backtrace, the machine just reboots14:16
tjaaltonanother crash15:58
apwtjaalton, i assume its not getting recorded in syslog?16:42
tjaaltonapw: no, I installed linux-crashdump hoping that it would catch it16:45
manjotjaalton, can you turn on kerneloops and catch it perhaps? 16:46
tjaaltonmanjo: does it take more than installing that package?16:47
manjoapt-cache search kerneloops16:47
manjokerneloops-daemon - kernel oops tracker16:48
manjokerneloops - kernel oops tracker16:48
manjokerneloops-applet - applet for the kernel oops tracker16:48
tjaaltonI had the daemon already16:48
manjoI believe that apport hooks for kerneloops also exists16:49
tjaaltonkerneloops was disabled, now running16:51
mdztjaalton, kerneloops will only help if something got logged16:53
mdzotherwise, you will need to use linux-crashdump16:53
tjaaltonthey are both installed now, but it seems that linux-crashdump only installs the changelog16:57
tjaaltonsome packaging goof?16:57
manjotjaalton, before you reboot does it give you enough time to even take a photo of the screen ?16:57
tjaaltonmanjo: no, it reboots itself16:58
tjaaltonbut of course I can't reproduce it anymore (at will)16:58
tjaaltonit happened three times by just logging in, opening a terminal and then browsing some directory with tab-completion :)16:58
manjotjaalton, what hw is this on  ?17:00
tjaaltonmanjo: thinkpad x61, intel17:00
tjaaltonI've got a newer libdrm/mesa though, could be related17:00
tjaaltonbut since linux-crashdump is essentially empty, there's no way to get a crashdump?17:08
tjaaltoncrashed again, but I see no dumps17:36
tjaaltonl-c seems to be a metapackage.. no wonder it doesn't install anything17:36
manjotjaalton, can you give us a clue as to where it crashes perhaps ? funciton name or something that flashes on the screen momentarily 17:43
tjaaltonmanjo: the display freezes for a moment, and the next thing is the thinkpad boot logo :)17:57
tjaaltonand l-c doesn't catch that. the example on wiki works18:03

rackerhackerjjohansen: i've built linux-ec2 properly via git, but i always end up with my total memory inflated by ~ 9MB: http://pastie.org/private/a78gpabfjnl94cn4uciq20:06
rackerhackerjjohansen: i've been digging through my .config for any option that would cause that to happen but i haven't had luck finding something20:06
jjohansenrackerhacker: are you doing i386 or amd64?21:03
rackerhackeramd6421:03
jjohansenright there was something about the mapping for the EC2 kernels21:04
jjohansenThe i386 base is at 0 but amd64 isn't21:04
jjohansenI need to refresh my brain give me a minute21:05
rackerhackerjjohansen: no problem ;) i appreciate the help21:05
NCommanderericm_, ping?21:20
manjoNCommander, can you get éclair out & fix the camera22:47
NCommandermanjo, wrong channel? :-)22:47
manjoNCommander, :) yeah wrong channel but right guy 22:47
NCommandermanjo, try #cyanogenmod, but I'm working on it22:48
manjoNCommander, they talk about GF's and such... not real andriod talk 22:48
NCommandermanjo, #android-dev?22:48
manjoI was on it and shouted for a little bit... 22:48
manjohmm let me try that 22:48
manjoNCommander, does your camera have this problem ? 22:51
NCommandermanjo, well, I'm not sure what the prroblem is specifically22:51
manjoNCommander, solarization - the image looks like I am looking thro a film of oil ... colors are all weired 22:52
NCommandermanjo, post a pic?22:53
manjoNCommander, email on the way22:57
manjoNCommander, did you get it ? 22:59
crimsunerm, this isn't normal, correct?  http://pastebin.com/d4273c26d23:13
bjfcrimsun, ah, no, that looks bad23:21
crimsunthat's stock 2.6.32-9.13-generic23:22
crimsunpurposely with all proprietary drivers deinstalled and some time after a fresh (cold) power cycle23:22
crimsunI've reproduced it using a brand new device (assuming identical) from retail23:23
crimsunalso reproducible on i38623:23
crimsun(i386 is a different machine entirely)23:23
bjfcrimsun, please file a bug, sounds like a regression23:23
crimsunyeah, I'm trying23:23
crimsunI can't seem to stay connected long enough to get through the LP auth process :(23:24
bjfcan you go hard-wired?23:24
crimsununfortunately, no (crappy netbook)23:25
crimsunI've already got most of it typed, so I'll just sneakernet it23:26
MTeck-Linuxany guess what I'm probably missing if all my partitions are recognized fine except for extended partitions?23:28
=== bjf is now known as bjf-afk
manjoMTeck-Linux, is your extended partition formatted ? 23:30
MTeck-Linuxmanjo: ya23:31
manjoMTeck-Linux, what does sudo fdisk -l say ? 23:32
MTeck-Linuxmanjo: I'm been messing aaround with the kernel23:32
MTeck-LinuxThis is the first partition during boot that the kernel panics on; /dev/sda5              19        1842    14651248+  83  Linux23:33
manjo/dev/sda1  or such ? 23:34
MTeck-Linuxthat mounts fine23:34
manjook23:34
manjoso your primary mounts ok 23:34
MTeck-Linuxyup23:34
manjoyou have /home on extended partition ? 23:35
manjowhat is the kernel version ? 23:35
MTeck-Linuxya23:35
MTeck-LinuxI'm using Ubuntu-2.6.32-10.14; but I've also been compiling it myself and taking some things out; that's where I'm missing something23:36
manjodid you modify fstab by any chance ? 23:36
manjoah ic 23:36
manjoso you have a custom kernel 23:36
MTeck-LinuxI could go through and enable a lot of stuff, i just thought I'd ask for an idea here23:36
manjohmm not seen that failure ... iirc 23:37
manjonot with stock kernels23:37
manjoone place I would check is to see if you fstab is not corrupted23:37
MTeck-Linuxit's not23:37
manjook23:37
MTeck-LinuxI only have one system; it's just something i disabled in the kernel that I need; I need to figure out what it is23:38
manjoyou could boot into a bash shell and try to manually mount your /home 23:39
manjoinit=/bin/bash I think23:40
MTeck-Linuxit's a kernel panic so that probably won't work23:41
manjodo you know where it panics ?23:42
MTeck-Linuxmounting /dev/sda523:42
manjovfs23:42
MTeck-Linuxoh...23:44
MTeck-Linuxthanks :)23:44
MTeck-Linuxnow where is that :P23:45
manjoMTeck-Linux, did you mess with any file system config options ? 23:45
MTeck-Linuxya23:46
manjolike enable devfs support or something 23:46
MTeck-Linuxno23:46
MTeck-Linuxbut I can't find either vfs of devfs by searching for it23:47
manjoyou can get the kernel source and look at the std config option and compare them with your modified options23:47
manjothe std config options should be under debian.master/config23:48
manjoif you have the kernel source you can look there 23:48
MTeck-Linuxthanks23:48
manjoconfig.common.ubuntu should have common config options 23:49
manjoMTeck-Linux, you could boot from live CD etc and see that your partition table is intact23:51
MTeck-LinuxI'm using the same system actually; using the default kernel until I get my own flying :)23:52
manjoah so *it is* your kernel .. ok 23:53
xteejxHi guys, sorry to bother you but bug 228302 has been triaged by myself and has been stale for a while, wondered if anyone from the team would mind having a look when you get a chance please? :)23:59
