apwRAOF (N,BFTL), I _always_ need a dose of bees09:25
yossarianukapw: sorry not sent a bug report yet about lack of oss modules yet - however I found an old post regarding it  - http://ubuntuforums.org/showthread.php?t=165619310:24
yossarianuk SNDDMA_Init: Could not mmap /dev/dsp. 10:24
yossarianuk- similar error for padsp10:25
yossarianukanyway - regarding rebuilding the ubuntu kernel source - I have found out what is causing the fail....10:25
apwyes?10:26
apwyossarianuk, ^10:27
yossarianuk(sorry @ work..)10:34
yossarianukill be a few secs..10:34
yossarianukok - it builds fine as long as I don't add CONFIG_LOCALVERSION:10:35
yossarianuki.e - append to kernel release10:35
yossarianukif I add anything in that - i.e 'test1' the kernel goes through the entire build process then fails 10:36
yossarianukif I leave that blank it builds the linux-image package fine10:36
apwyossarianuk, sounds about right indeed.  you should add something to debian.master/changelog, to the top entry'10:37
apw+test1 to the end of the version number on that line10:37
yossarianukapw: ah - i.e the dch command ?10:38
yossarianukor just manual edit ?10:38
yossarianuki'll give it a go10:38
yossarianukthanks10:38
yossarianukThis documentation should be updated.....10:38
yossarianukhttps://wiki.ubuntu.com/Kernel/BuildYourOwnKernel10:38
apwmanual edit i would recommend10:39
yossarianukthanks - i'll try that !10:39
yossarianukregarding the OSS snd issue - the apps are 32bit (on a 64bit system)10:39
yossarianukI should have the right deps though10:39
yossarianukand also it works 100% with a compiled kernel with oss mods...10:39
yossarianukI will make a bug report ...10:39
apwyossarianuk, yep, community member edited that document to add that section which is, wrong ... sigh10:42
yossarianukwell not wrong - just not complete.10:46
yossarianukYou just can't get the staff.........10:47
apwyossarianuk, no blatently wrong, using CONFIG_LOCALVERSION (as you found out) breaks the build10:47
apwyossarianuk, though i am slightly supprised that the config-check didn't implode for that and stop you10:48
yossarianukapw: ah - so when I re-test should I just add to debian.master/changelog or do I add to debian.master/changelog as well as CONFIG_LOCALVERSION  ?10:48
apwjust add it to debian.master/changelog, nothing else10:49
yossarianukapw: thanks10:49
apwthe rest should come out in the wash as the build system runs10:49
yossarianukI can see if I have edit rights and change this ?10:49
apwyossarianuk, i have already updated it10:49
yossarianuk(want to test first anyway..)10:49
yossarianuknice one!10:50
apwit is a wiki, it is easy to edit, which is both good and bad10:51
apwdepending on how knowledgable the editor10:51
yossarianukyeah - you sometimes get people (trolls) on purposely adding 'bad data'10:52
yossarianukapw:  just to confirm I should change the first line in debian.master/changelog11:02
apwyes11:02
apwlinux (3.19.0-3.3) UNRELEASED; urgency=low11:02
apwlinux (3.19.0-3.3+test1) UNRELEASED; urgency=low11:02
apwlike that sort of thing11:02
yossarianukgreat cheers11:02
yossarianuki'll let you know if that works ....11:03

Odd_BlokeI'm hitting this error when running the kernel tests: http://paste.ubuntu.com/9806187/14:53
Odd_BlokeI tried running them with sudo (i.e. sudo ./runner qa) which did address this, but other tests fail if they're run as root.14:54
Odd_BlokeI can poke at fixing it myself, but didn't want to do so if someone could point me in the right direction. :)14:54
apwOdd_Bloke, doesn't that show it running that failing sub comamnd as root ?15:04
apwOdd_Bloke, ie with a sudo ?15:04
Odd_Blokeapw: No, ./runner is being run as the ubuntu user.15:11
Odd_BlokeI think it isn't logging what is failing.15:11
apwOdd_Bloke, but the commands which are run have sudo on them in a lot of cases, perhaps the failing one needs it adding15:11
apwOdd_Bloke, rather than running the whole of runner as root15:12
apwOdd_Bloke, as clearly it expects to need to do that15:12
Odd_Blokeapw: The failure happens in the call to shutil.copytree, which is within runner (i.e. the only way to get that particular line to be privileged is to run runner as root).15:13
apwOdd_Bloke, do we know where it is trying to copy too ?15:13
Odd_Blokeapw: I believe the three elements of the tuple in the shutil.Error line are from, to and error text.15:14
Odd_BlokeLet me pull down that directory and see what does end up in there.15:17
Odd_BlokeOh, of COURSE it worked this time.15:20
apwOdd_Bloke, oh good :<15:36
Odd_BlokeI'm trying another full run, in case that's what triggered it.15:39
apwyeha its going to be like first date nurves or something15:39

hallynapw: do you know of any firmware bug in recent sru which sould have prevented a desktop system from mounting some drives/filesystems?  20:54
=== Laney is now known as Guest54456
sforsheehallyn: which release? I think the only recent firmware SRU was some intel wireless updates.21:28
hallynsforshee: 2015-01-19 20:33:12 upgrade linux-firmware:all 1.127.10 1.127.1121:30
sforsheehallyn: yeah, that one was only updates for iwlwifi21:30
hallynthere was also a libc6 and multiarch update, maybe those are more likely21:31
sforsheeI suspect so. That would be some bad wireless firmware if it caused mount issues.21:32
hallynwell, or a bad grub-update or something?21:34
infinityhallyn: Blaming glibc for being unable to mount some filesystems seems far-fetched too.  What's the exact symptom?22:08
hallyninfinity: i didn't say i blamed it for not mounting the fs.  all we know is it didn't get to mounting filesystems22:10
hallynthe bug was reported third-hand, and machine owner does not speak english22:10
hallynbug reporter and victim machine (and its owner) are on differnet sides of whatever country they are in22:10
infinityhallyn: Brilliant.22:11
hallynhm, what's your lp id actually?22:11
infinityhallyn: So, it's hard to say without seeing the exact symptoms, but the bug/misfeature I run into all the time (just had to fix it on the ppc porter a few days ago) is that if fstab references a mountpoint that doesn't exist, mountall can hang.  Which is something you never notice until a reboot.22:12
infinityhallyn: adconrad22:12
infinityhallyn: A boot with init=/bin/sh and grubbing around in fstab can often be enlightening.22:12
hallyninfinity: yeah that appears to be impossible, though iiuc maybe after feb 7 he can d oit.  sigh22:13
hallyn(subscribed you to the bug :)22:13
infinityhallyn: #?22:13
hallynthe reason it interested me is bc it seemed similar to a container bug stgraber was seeing, where he is guessing that upstart's reexec failed22:13
hallyn141267122:13
infinityhallyn: Oh.  Weird.  Kay, if downgrading fixed it, it's not the mountall thing.22:14
hallynyeah, i really think if they'd powered it down and back up it would have been fine, just reexec failed.  22:15
infinityhallyn: Err, but the bug is that it fails *on boot*.22:15
infinityhallyn: Not on upgrade.22:15
infinityhallyn: Really tempted to blame cgmanager. :P22:16
hallynyeah, well, i'll try to reproduce in a kubuntu vm i guess22:16
hallynwho knows, maybe it *is* cgmanager22:16
infinityThen again, I don't speak fluent nih_, but I don't see how the 7.1->7.2 delta could make things more broken.22:18
hallynor more importantly how cgmanager could block the system booting.  22:19
infinityYeah, that.22:19
infinityhallyn: The upgrades/downgrades may well be a red herring, and he may just have a racy boot that's showing an intermittent mountall or upstart bug.22:20
hallynchuckle.  good point22:20
infinityhallyn: But yeah, without the ability to do some good back-and-forth, it's kinda dead in the water until Feb7 anyway.22:21
hallynasked fo ra few more reboots :)22:21
hallynone would expect more such reports if this was a real sru regression22:22
