Madkisshi folks!11:30
MadkissI just realized that linux-image-3.2.0-24.37-virtual is missing DRBD11:31
Madkissor rather, drbd.ko11:31
Madkissis there any particular reason for that?11:31
smbMadkiss, for virtual only a limited set of modules is in the kernel package. There is an extras package containing the rest11:41
smblinux-image-extra-virtual11:41
ogra_sounds like "linux-image-very-unreal" :P11:42
Madkissdid that change between -23 and -24?11:43

jdstrandjsalisbury, bjf: hi! have you seen these bugs in Ubuntu on recent lucid kernels: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=656899, https://bugzilla.redhat.com/show_bug.cgi?id=783823 and https://bugzilla.redhat.com/show_bug.cgi?id=783955. it seems like the fix for CVE-2011-4127 is what is causing it. RedHat says it is just noise and not a problem. My system seems fine otherwise12:38

ckingbrendand, how can I help?12:41
tgardnerjdstrand, I think this is a known log filler annoyance, but otherwise benign12:42
jdstrandtgardner: thanks-- that was the conclusion I was coming to, but wanted to be sure12:42
* jdstrand adds something to logcheck 12:43
brendandcking - i have a strange situation where the same fwts command is running on clients but erroring on servers12:43
brendandcking - i'll pastebin it. two ticks12:43
brendandcking - http://paste.ubuntu.com/949688/12:44
brendandcking, same command runs fine on my own system running precise12:44
brendandcking, it fails on all our servers12:45
ckingbrendand, I suspect it is trying to write to fwts.log but that is not writeable12:47
ckingwhere is this log file, does it already exist but owned by someone like root?12:47
brendandcking - the file doesn't exist yet12:47
ckingbrendand, where are you running it? 12:48
brendandcking - ah, i thought i put the path in the pastebin. i see what you mean, let me try something else12:49
brendandcking - ok, so that might have been a red herring. it's still failing on all our servers though. i'll do a bit more looking12:50
_rubentgardner / smb: acpi=off, pcie_aspm=off/force : no go ... pci=use_crs : boots12:50
_rubenthe latter was suggested in the error i got with the pcie_aspm options, and then to file a bug12:51
smbHm, ok... IIRC that was related to some degree how to set up bridge windows (top down or bottom up). But as you said this is first trial with Linux...12:53
_rubenhttp://pastebin.ubuntu.com/949707/12:53
_rubenat the end of that paste, the other attempts would be hanging12:54
_rubenso yes, it's related to the bridge windows12:54
smbRight, though probably more in the sense that the information from acpi is ok but the bios is pre 200812:55
_rubenthat's very likely12:55
_rubenthe pre-2008 part12:56
_rubenstill looking for my update dvd to fully update it, tho given the ancient hardware, i wonder if there'd be much newer bioses avail12:56
smb_ruben, I would be surprised. I rather meant its like the message says. Reporting an upstream bug to add the machine data into an exception table 12:58

smb_ruben, Heh, yeah. At least for you use-case the 2010 date will give you automatically the use_crs ...13:26
_rubensmb: guess we'll see in a bit .. firmware updates (bios/raid/etc) tend to take a while on these dells, once it's done, i'll try to boot without special params13:27

RobinJ1995i think i found what caused it!16:29
RobinJ1995If I open the Sound settings panel, no sound device is selected, but the sound is working. The sound stops working from the moment I select one. That's why I can't undo it, because there's no way to "unselect" the only item in the list.16:30

greearbHello!  I'm planning to re-spin the 12.04 LTS desktop cd with a modified 3.3 kernel.17:16
greearbIs this the upstream 3.3 kernel:  http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-quantal.git;a=summary ?17:16
tgardnergreearb, v3.4-rc417:18
dilekscheck Makefile :-)17:18
greearbok, is there an upstream 3.3 with ubuntu patches applied?17:19
greearbfor that matter, would a stock 3.3 kernel work on the live-cd?17:20
dilekshttp://kernel.ubuntu.com/~kernel-ppa/mainline/17:22
greearbhappen to know where the git trees for that are?  I need to add my hacks on top of 3.3.3 17:24
dileksgreearb: unfortunately, no17:32
greearbbummer...  Think maybe the v3.4-rc4 tree has some tags that would be something similar to 3.3 + ubuntu patches..or maybe it is rebased on top of the latest upstream when moving to 3.4-rcX?17:35
greearbguess I could run -rc4, but that is liable to be painful :P17:35
dileksgreearb: want to test some wireless stuff?17:40
greearbyeah, and the rest of my patch set17:40
greearbsome of which is too crufty to ever make it upstream :)17:40
dileksgreearb: I use a -generic kernel-config and build upstream GIT with make deb-pkg17:45
greearband that is enough to boot a live-cd?17:46
greearbI was afraid there might be some special patches to make that work that are not upstream...17:46

greearbgoing to poke around the 3.4-rcx tree and see if I can find some branch that does what I want17:48

dileksdue to viro union-mounts is favourized17:49
dileksdunno status17:49
