MAbeeTThi I recently updated to oneric (3.0.0-16-generic x86_64 x86_64 x86_64 ) I tought that suspend problems will desapear with 3.0 kernel02:04
MAbeeTTbut I've been wrong :(02:04
MAbeeTTHow could I help to solve the suspend problems? 02:04
MAbeeTTI suspend, when I start again the system, the keybard doesn't work, there is no screen, or it stars "from zero".02:05
MAbeeTTthanks02:05

sashalHello all09:39
sashalA question to the security team: It looks like only half of the CVE-2011-4347 fix was pulled into the tree, was the 2nd part skipped on purpose?09:39
ubot2sashal: ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem.  When the candidate has been publicized, the details for this candidate will be provided. (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4347)09:39
apwsashal, that number is familiar09:54
sashalapw, It's the KVM device assignment problem09:54
apwsashal, the second fix was added to the CVE late (after it was USNd I suspect) and I beleive it is being released (the second part) in this round of SRU updates.09:56
sashalapw, It was done in the same patch series as the original fix, that's why I thought it's weird in the first place09:56
apwsashal, yep, somehow the original security report only had one, the second was added some days later and we'd already spun the security update09:57
sashalAh, Cool09:57
sashalThanks!09:57
apwanyhow, its being done for sure if its not already out for testing09:57
apwno idea how they will handle the USN given it went out once already10:00
sashalbtw, is there a timeframe in which the USN comes out after the release? Some times it takes couple of days after the kernel was moved into the production repository for the USN to come out10:03
apwsashal, i am unsure, thats handled by the ubuntu-security team, they have some manual process to ensure eyes are on things; probabally how the error was spotted in the first place10:04
apwppisati, are you planning a further rebase for precise/ti-omap4, or waiting till leanns next upload??11:39
ppisatiapw: more stuff to come, don't upload yet 11:56
ppisatiapw: i just found out there's a critical still open for P/omap4 (i was lost in perf land till yesterday)11:57
ppisatiapw: so either i fix it by tonight or i'll ask for a revert to the previous TI BSP + stuff we have on top of HEAD now11:57
ppisatitgardner: FYI - ^^11:57
tgardnerppisati, ack11:58
apwppisati, ok thanks12:02
apwppisati, i assume you are saying that will occur as a quick fix for B2 and then you'll fix it properly sort of thing ?12:03
apwcking, did i hear rumours you were talking to people about the aspm-1.1 issues ?12:03
ckingyep12:04
apwtgardner, i see that ericm said that they were sending out that ath5k thing with a new version number, but i recall you applying the firware with the current name, are we going to be broken in the future by that ?12:05
tgardnerapw, only if the firmware _isn't_ backward compatible, though Atheros says it is.12:05
tgardnerapw, besides, I assume that'll be 3.4 material12:06
apwtgardner, does this mod_probe stuff have a CVE associated with it, i have a vague feeling it might12:08
tgardnerapw, not that I could find. jdstrand stumbled across it this weekend, so I picked it up myself12:08
apwtgardner, i could swear i have read a cve for it, but cannot find it in our list ... sigh12:09
ppisatiapw: yes, if i can't make HDMI output to work by tonight, i'll take latest master + previous TI BSP (where hdmi output was working) + latest patch on top of P/omap4 (cross compile fixes + pperf revert) just for beta212:10
Teduardohowdy, does anyone know if there will be a new version of the kernel for lts 10 installer so that we can install it on Dell 12 Gen servers?12:10
ppisatiapw: in the meantime i'll keep trying to find the root cause of the breakage with the new TI BSP code12:10
tgardnerTeduardo, by Tuesday.12:10
Teduardooh thats good news i read somewhere that 10.04.4 was going to be the "FINAL" release12:11
tgardnerTeduardo, oh, lts 10. I'm thinking 12.04.12:11
Teduardoand that made me want to curl up in a ball and cry12:11
tgardnerTeduardo, 10.04.4 _is_ the last release12:11
Teduardoack12:12
tgardnerTeduardo, you can't get an install to work from the 10.04.4 DVD ? Every kernel through Oneiric is available on it12:12
Teduardoah, we can't do dvd installs, everything we use is pxe =(12:13
tgardnerTeduardo, well, you could craft your PXE boot _from_ the DVD12:13
Teduardoall I really need is a kernel and initrd that supports the new NIC and new LSI controller12:14
tgardnerTeduardo, which is why I pointed you at the DVD. the installer supports multiple kernels.12:14
bullgard4When booting, Ubuntu 11.10 performs: " * Starting Mount network filesystems. [OK]". But why does it immediately therafter perform the opposite:" * Stopping Mount network filesystems. [OK]" ?12:18
Teduardotgardner: okay, I think currently the only one that works on this platform is 11.10, I'll have to just use that it seems12:18
tgardnerTeduardo, well, you'll have 12.04 soon12:19
tgardnerTeduardo, in fact, you should be testing it now12:19
Teduardohopefully the installer works in the first release, usually there is almost always some kind of LVM menu loop that breaks kickstart12:19
Teduardoor it tells me it can't find a disk to install on even though fdisk -l shows /dev/sda... etc12:20
tgardnerTeduardo, I've been doing 12.04 PXE installs on a variety of platforms.12:20
Teduardoah i'm talking about my experience with 11.1012:20
tgardnerTeduardo, have you filed a bug ?12:21

ckingmjg59, for these PCIe ASPM hangs on boot it seems we could be hitting a BUG_ON in pcie_aspm_configure_common_clock() because the child isn't apparently pcie capable.13:56
mjg59Just. What?13:57
ckingmjg59, it makes no sense, but we got a user to get a full stack dump and it seems (I may be wrong!) that BUG_ON is being called13:58
mjg59cking: Oh right I see. Argh.13:58
mjg59Yes, this is just about possible.13:58
ckingI suspect the BUG_ON is being a bit harsh13:58
ckingfor the life of me I can't see why this is biting us now14:00
mjg59cking: http://fpaste.org/bOQm/14:00
* cking mulls on that for a moment14:02
mjg59cking: Prevously we'd bail if any children weren't pcie. Now we won't.14:02
mjg59We need to continue to do so in order to avoid the BUG_ON14:03
ckingah, that's we are being caught out14:03
ckinggot it14:03
* cking will give it a spin14:04
ckingmethinks mjg59 is always at least 24 hours ahead of me 14:06
mjg59cking: Thanks for that - I don't think there's any way I'd have figured it out otherwise14:07
ckingmjg59, no problem, getting a full stack dump and walking it through was the easy bit, I got stumped at why the BUG_ON was happening14:08
mjg59cking: I think I'll just send that - it's Obviously Correct(tm)14:10
ckingheh, I can also get the users to verify it to sanity check that, but it normally takes ~24 hours 14:10
ogasawaracking: let me know when you get confirmation on the patch, there may be time to squeeze it in for Beta-214:41
ckingogasawara, yep, will do14:41
* ogasawara back in 2014:41
tgardnerogasawara, I just plucked it from the stable mailing list and applied it.14:41

MAbeeTTthe problem existis via pm-suspend command or "suspend option in unity/gnome"15:13
MAbeeTTthanks15:13
ogasawaratgardner: I'm inclined to upload it15:15
tgardnerogasawara, I was gonna ask if you were willing to.15:16
ogasawaratgardner: I am, as I think that bug is going to affect a few systems if we don't15:16
tgardnerabsolutely15:17
ckingyep15:17
tgardnerogasawara, I've smoked tested it, but not on an affected platform. cking should get one via fedex yet today perhaps15:18
ogasawaracking: Ooo, you're sure you'll get a system today?15:18
ogasawaracking: if that's the case, I'd maybe wait to upload to get confirmation of the fix15:18
ckingogasawara, normally they arrive after lunch, now it's past 4pm, so it's looking slim15:18
tgardnerogasawara, I still think its worth it. besides, there are abunch of other patches that need to get into the pipeline15:20
ogasawaracking: my thoughts are I'd upload even without test verification.  we've already rendered the machines unbootable, it can't get too much worse.15:20
ckingindeed15:20
ogasawaratgardner: I was only planning to pick this single patch, are there other's you wanted in?  as I'd need to justify them to the release team.15:21
tgardnerogasawara, seccomp ?15:21
tgardnerogasawara, bunch of AA fixes as well.15:21
tgardnerI forgot we're still awaiting B215:22
ogasawaratgardner: right, seccomp should already be uploaded as I squeezed it in before beta-2 freeze.  the latest AA patches I didn't think were critical for Beta-2 and could wait till after.15:24
tgardnerogasawara, ah right. I missed the Ubuntu-3.2.0-20.32 patch in master-next. 15:25

tgardnerppisati, so that is some seriously bizarre shit you did with the ti-omap4 branch. are you gonna work on what regressed ? might have been something in the 3.2.13 stable updates.15:59
ppisatitgardner: yes, it came with latest rebase15:59
ppisatitgardner: i'll figure out but i want beta2 to be safe16:00
ppisatitgardner: TI BSP is the same, so there's something from upstream that kills hdmi output16:00

ppisatitgardner: cool, thanks16:01
tgardnerppisati, do you not have the right HW to have detected the HDMI regression ?16:04

apwinfinity, bah you slave driver you18:46
infinityHahaha.18:46
apwTheMuso, we need to get some SOPs for the lowlatency kernel when we need to do emergency updates such as was desired today18:46
infinityapw: AIUI, the patch will break pre-v6 (which is why it's not yet upstream), but we don't give a hoot about anything pre-v7, so it seems sane to me to carry the fix.18:46
apwinfinity, assuming you've tested it on some of the affected kit that seems fine18:47
apwinfinity, have we ?18:47
infinityThe user who reported it has.  I can certainly spin something up "later", FSVO "later".18:47
infinity(If it's any comfort, it's also in 95% of the v7 Android trees out there)18:48
apwheh no comfort at _all_ frnakly18:48
infinityHahaha.18:48
infinityYeah, that's a fair point. :P18:49
infinityWell, once I get this grub bug nailed to a wall, I'll see if I can do some local testing of this patch.18:49
infinityUnfortunately, there's no particularly sane way to test it beyond smoketesting that it boots and doesn't crash.18:50
infinitySince the condition required to reproduce the bug it's fixing is "lots of random luck".18:50
apwi more care that the boards we care about continue to boot with it18:50
* apw spins a kernel with it18:50
infinityYeah.  That's almost certainly true just from eyeballing the patch, but I can test to confirm.18:51
ppisatiapw: do you want me to take care of 965840?18:51
apwppisati, s'ok for now as i have the patch and its likely master material18:51
apwinfinity, that reminds me where are all the other deviant kernels on that bug, the source trees ?18:51
infinityapw: mx5 is a linaro kernel, and ac100 is jani's baby, not sure where he keeps the tree.18:52
ppisatiapw: ok18:52
infinityapw: In both cases, I'll probably just update the precise kernels myself, and let the respective maintainers sort out their gits later.18:52
infinityapw: (And I'm not wildly concerned about SRUs for the weird kernels, just for omap/omap4, since we use them as buildds)18:52
apwinfinity, which random old crap are you wanting this on18:53
apwinfinity, ^^18:55
infinityapw: omap4 natty and newer, and for master, everything you're still doing SRU napalm runs for, I guess.18:56
apwinfinity, can we not get those buildds onto one release, at least to reduce the exposure when we have something real bad18:57
infinityapw: My hope is that all the buildds will be precise "soon".  But it's not really up to me. :/18:57
infinityapw: If I still had root on them, they'd all be 3.2.x right now. :P18:57
