* apw finally gets his machine updated and booted08:58
apw1 day suspended, 200M of updates, sigh08:59
* smb reboots to get'em active09:11
* smb seems to be back09:16
smbJust the screen vomit between lightdm and the desktop is always making me feel a little discouraged09:17
apwi don't get that i don't think09:18
Davieysmb / apw: I'd really like to bounce an idea off hallyn, but he is on hols.  What do you chaps think about enabling kvm vmx nested by default?09:21
smbI think its the radeon driver forgetting to clear the graphics ram before displaying it09:21
apwDaviey, does it even work ?09:21
Davieyapw: yeah!  But not decalred as ready as svm, which is why upstream don't have it such.09:22
Davieysvm nesting is enabled OOTB09:22
smbDaviey, It would be nice if thoughts of enabling things would be presented before feature freeze though09:23
apwDaviey, what option is it ?09:23
Davieyapw: I'm still not entirely sure TBH.. I think it's actually a userspace thing.09:23
apwi don't see any options mentioning nesting anyhow, kernel side09:24
DavieyI think it is enabled kernel level, but just not exposed.09:24
Davieyapw: I think it's a modprobe option?09:24
apwi then think, we know so little about it we cannot comment09:24
* smb agrees09:25
Daviey$ modinfo kvm_amd | grep -i nested09:25
Davieyparm:           nested:int09:25
Daviey$ cat /sys/module/kvm_intel/parameters/nested09:25
DavieyY09:25
DavieyOkay, thanks anyway..09:25
apwDaviey, sounds like the kernel side is all there, so ... as you say sounds like a userspace side thing09:26
Davieyapw: Right, it was more of a 'have you heard that doing this would be NUTS?' kinda thing. 09:27
smbno, but then we usually just stick to the defaults as long as nobody asks for something specifically. and the defaults cannot be nuts otherwise they would not be defaults... :)09:29
apwDaviey, heh, no i think i only heard that we now had nesting at all this week actually09:29
Davieyok, thanks :)09:32
smbRAOF, Is that something that you are aware (not so clean transition between lightdm and desktop for radeon) off or think it should be addressed?09:33
htorquebryceh: hi! bug 899159 - this seems to be fixed in the xorg-edgers ppa, but i'm still getting (worse) hangs, just with a different number (0x7a000002 instead of 0x7b009004, which i initial got, but later couldn't reproduce anymore).09:57

htorqueshould i open a new bug report (upstream?)?09:58
ckingapw, can you forward me the canonicloud scripts you were talking about yesterday evening?10:40
apwsmb, you wrote maint-getabis right?  seems it is trying to get ppc64 for oneiric for hendrix11:46
henrixcreating the ignore file didn't work11:47
apwII: linux-image-3.0.0-16-powerpc64-smp_3.0.0-16.29_ppc64.deb11:47
apwII: Downloading to kernel.ubuntu.com ... FAILED!11:47
apwhenrix, i think you can just ignore the fact it tried and failed to do it11:47
apwyou cirtainly don't need any files for ppc64 as the kernel is never built there11:48
apwso it cannot fail the abi checks11:48
henrixoh, unless... the ignore file should be debian.master/.../powerpc/ppc64.ignore and not debian.master/.../ppc64/ignore11:48
apwhenrix, though i would also say that in the tip of oneiric/master-next that i have, the ABI files are already up to date too11:48
apwhenrix, there is no point in making any files with ppc64 in their name11:49
apwth11:49
apwthere is no such architecture11:49
apwthe error about ppc64 can be ignored, as there really really never are any and cannot be 11:49
apwthat is not a valid ubuntu architecture at all11:49
henrixapw: ok, cool. so i'll just ignore the failure and later on confirm with the guys what they usually do11:50
henrixapw: thanks11:50
RAOFsmb: Yes, I'm aware of that; I don't think it's a kernel or X bug; I should be able to get to it tomorrow or early next week.11:55
* RAOF sleeps11:56
apwcking, those examples will be needing updated for you, i am just retesting them now12:30
apwcking, some of the command output has changed format12:31
apwcking, ok branch updated with fixed offsets12:34
=== yofel is now known as yofel_
=== yofel_ is now known as yofel
smbapw, Yes I wrote it. Possibly it needs ppc blacklisted. It would try to get anything that control.d indicates. Which is not always true13:37
apwsmb, there is a config in debian.<branch>/etc/getabi as well which lists the right things to get13:38
smbapw, Nowadays maybe. This was working way before13:38
smbAnd not sure it would be true for hardy...13:38
smbanyway henrix may have a look at IgnorePatterns in the source script13:39
henrixi will be taking a look at it later. i added this issue to my todo list.13:39
henrixfor now, i just ignored the ppc64 failure so that i can go ahead with the sru13:39
smbhenrix, ok. basically its likely just a IgnorePatterns["oneiric"] = ² ".*_ppc64.deb" ] 13:41
smbor whatever the package file would look like13:41
smbs/²/"/13:41
henrixsmb: yeah, i've seen that on the script. i'll give it a try13:42
smbhenrix, If you later have a line that works for you, let me know then we can commit it to the repo13:43
henrixsmb: sure, i'll let you know. thanks13:44
henrixsmb: so, there are not releases supporting pp64 atm, correct?13:44
henrixsmb: i mean, this arch shall be *always* ignored?13:44
smbhenrix, That would be the meaning. I am just not completely sure this is true for oneiric and why nobody else had the issue otherwise13:45
smbI know we were talking about dropping some ppc flavour though I thought for precise13:46
henrixsmb: this issue has been detected before by the other guys. its just that its not sorted out yet, due to these "unknowns" about the ppc support13:47
henrixsmb: at least, that was my understanding13:48
smbhenrix, Yeah, ppc comes and goes. its confusing13:49
henrixheh13:49
henrixthanks for your help. i'll let you know later when i revisit this script13:50
apwsmb, though in this case the failures are all ppc64, which never was an arch13:50
smbinux-image-3.0.0-16-powerpc64-smp_3.0.0-16.29_powerpc.deb13:50
smbprobably meaning ppc64 as the flavour13:51
smbSo maybe the logic to find the right name is broken 13:51
henrixthe failure is in linux-image-3.0.0-16-powerpc64-smp_3.0.0-16.29_ppc64.deb13:52
henrixlinux-image-3.0.0-16-powerpc64-smp_3.0.0-16.29_powerpc.deb13:52
henrixis working file ^^13:52
henrixs/file/fine13:52
smbHm, maybe a side effect from apw'S cleaning up the description13:53
henrixdescription?13:53
smbI could be wrong. As much as I remember I try to make sense of what the vars.* files describe13:55
smbMaybe just something I did not see when the script was written13:55
hertonapw, smb, I think this problem on maint-startnewrelease started with commit 3784816027fe117b43042d1ac5dff20bdc3579aa on natty repository, why that ppc64 stuff was added?13:56
apwherton, because there was going to be a new arch, then there wasn't13:56
apwas that is not hte official configuration for getabi, noone had noticed13:57
smbSo ok. In that case ignoring it sounds fine to me13:57
apwand it being there is safe in the archive13:57
smbba no wonder nobody speaks to me on mumble... f...13:58
apwsmb, ?13:58
hertonyes, just confirming, it was what I had got previously I think, we always ignored it13:58
smbapw, It broke13:59
smbNobody *can* hear me13:59
apwsmb, ahh you are there but no lips indeed13:59
smb*sigh*13:59
apwsmb, flip some things randomly bound to help14:00
smbapw, Well what I was saying to myself was that ppc64 in some way as a flavour name and a potential architecture is so little chance of not being confusing.  Especially when it never comes14:02
tgardnersmb, i386 is to amd64 as ppc is to ppc64 ?14:03
smbtgardner, Not that I would be knowledgable there. But it would be my impression14:04
tgardnersmb, I think the ppc64 possibility is really dead now.14:05
apwindeed powerpc is 32bit userspace (but has a 64bit kernel option) ppc64 would have been a 64bit userspace14:05
smbMabye just without the need to be compatible14:05
hertonmay be the ppc64 stuff should be removed if it will not come as a new arch on the distro, I don't know, do we know if it'll really come?14:05
smbapw, Isn't that a bit different from what we thougt?14:05
apwherton, it was left in cause it doesn't really do any harm 14:06
apwas nothing uses it even as tehre is no architecture14:06
apwand it was a pig to get working and keep up to date14:06
apwbut there is also no reason to have it in anything other than P currently, probabally Q14:06
apwso if it causes issues ripping it out isn't a problem14:07
smbherton, Similar issues existed before, for that reason the ignore lists in getabis exists.14:07
hertonsmb, sure, no problem in using IgnorePatterns for now14:13
smbMaybe this time I can even put some explanatory comment there, so I will remember in two weeks14:15
ckingapw,  thanks for sorting out the scripts for me14:21
apwcking, np they wern't working for me anymore, and i'm going to need em once uds opens14:22
hertoncking, I spammed yesterday the ecryptfs bugs for verification, I think most of them or all can be put as verified already where they are patches that went to stable in other releases, but natty didn't picked up as as 2.6.38 doesn't have stable releases anymore. Just did the normal spamming just in case as it is not clear whether we should verify stable patches that ended up in other releases (well extra testing will not do any harm if there is 14:26
hertontime to do them...).14:26
herton*ecryptfs bugs for natty14:27
tgardnerherton, I marked at least one of the natty ecryptfs bugs as verified14:27
hertontgardner, ack14:27
ckingherton, I verified the other 3 this morning14:27
hertoncool, yes saw sru-report now and everything is ok.14:28
ckingI did a clean -i386 install and ran the ecryptfs (and a manual test) to verify they worked - so it was a good sanity checking exercise14:29

apwjjohansen, would the following be bad:16:03
apw[   44.510396] type=1400 audit(1331219759.479:9): apparmor="DENIED" operation="create" parent=772 profile="/sbin/dhclient" pid=773 comm="dhclient3" family="inet" sock_type="dgram" protocol=1716:03
apwjjohansen, might that indicate we are preventing dhcp from working ... owner of the machine is reporting that they no longer have network16:04
apwogasawara, i have an update for the hyper-v support i'd like in the next upload, when is that likely to be ?16:41
ogasawaraapw: was going to plan one for tomorrow16:41
ogasawaraapw: go ahead and shove any patches you want in to master-next16:42
apwogasawara, sounds good, will have them tested finally today and get them in16:42
* cking reboots his AP17:46
apwogasawara, ok tested successfully, and patches pushed17:48
ogasawaraapw: ack, thanks17:48
brycehhtorque, yeah since that one is believed fixed, let's start a fresh bug report.  18:07
=== tgardner is now known as tgardner-lunch
htorquebryceh: should this directly go upstream?18:45
brycehhtorque, yes but would be nice to also have a launchpad bug for us to track18:46
brycehhtorque, so do `ubuntu-bug mesa`, attach the dmesg and i915_error_state, steps to reproduce, and so on18:47
brycehthen similarly to file it upstream.18:48
brycehif that seems like too much hassle, file the LP bug and I can forward it to fdo18:48
htorquebryceh: it would be great if i could create such an apitrace log file, so this could be reproduces easier (right now i trigger it with a game installed through wine :-/). you don't happen to know how i can get such a log file?18:50
htorque*reproduced18:50
brycehno I haven't played with apitraces myself so far, but agree that would be helpful to have18:51
brycehhtorque, I'll find out for you18:51
thomiHi - for about a week now my webcam isn't recognised in precise. It doesn't show up in /dev/video0, so I'm guessing it's a driver issue. What can I do to diagnose and debug the problem?18:52
brycehhtorque, alright this seems to be the best doc on using it:  https://github.com/apitrace/apitrace/blob/master/README.markdown18:54
htorquebryceh: thanks18:54
brycehhtorque, so, git clone https://github.com/apitrace/apitrace.git18:54
htorqueyeah, i have that18:54
brycehok, cool so looks like it's called via `apitrace trace --api API /path/to/application`18:55
brycehhtorque, hope that helps, let me know how it goes18:56
htorquebryceh: will try it soon, i just hope it likes wine18:56
=== tgardner-lunch is now known as tgardner
htorquebryceh: oh, i just read that it can trace but not retrace directx calls. do you think i should try it anyway?19:12
brycehoh, hrm19:13
brycehwell, couldn't hurt I guess19:13
brycehhtorque, hmm you know wine might have a similar trace dumping thing19:13

PioneerAxonYeah, but I didn't plug in anything...21:42
PioneerAxonsuddenly, it started using max CPU,21:42
ohsixlsusb shows no devices? could be a mechanical problem too, or just a bug21:42
PioneerAxonno new devices on lsusb21:43
ohsixany devices.21:43
PioneerAxonafter restart, it is working normal21:43
PioneerAxonyeah, I have webcam installed on usb21:43
PioneerAxonFYI, I am on laptop..21:44
PioneerAxonI guess, it would be some unknown problem, because I am using this kernel from a long time without any problem..21:45
PioneerAxonunknown factor*21:46
PioneerAxonAnyways, Should I submit  the log??21:47
JanCPioneerAxon: next time please use paste.ubuntu.com or another pastebin if you want to show something longer than 2-3 lines...  ;)21:48
PioneerAxonOkay, sure... Sorry for that..21:48
JanCPioneerAxon: is this a one-time issue, or something you see often?21:50
PioneerAxonNo, this is the first time, anything happened, which forced me to shutdown..21:51
PioneerAxonJanC: I am going to remove both logs, kernel.log and syslog. As no much useful information in those file, taking 1.5 Gigs on my disk..21:55
JanCPioneerAxon: not as bad as the 50+ GiB ~/.xsession-errors I had recently...  ;)21:59
PioneerAxonOMG!! 50 GB!! This is insane..22:00
PioneerAxonJanC: how would anyone even handle that big file?? It is too much for any editor/tool..22:02
JanCeh?22:02
JanC'less' handles it fine  ;)22:02
ohsixso would vim ;]22:03
JanCas do grep etc.22:03
PioneerAxonNo, I was talking about more GUI based log viewers...22:03
ohsixless useful22:04
JanCit's just really weird if you suddenly get out of diskspace errors on a $HOME where you didn't save/download anything but a couple of small documents recently22:04
JanCPioneerAxon: GUI-based log viewers can handle that if they are well-written...   ;)22:05
