[06:13] <ppisati> moin
[07:13] <smb> morning
[07:28] * smb enjoys non-charcoaled coffee...
[07:31] <jk-> moving up in the world, hey?
[07:31] * ppisati actually likes the American coffee...
[07:32] <smb> ppisati, pervert! ;)
[07:33] <ppisati> yes i am :)
[07:33] <smb> jk-, More "right"
[07:35] <jk-> next it'll be non-charcoaled charcoal
[07:35] <ppisati> rsync after a travel takes forever...
[07:37] <smb> jk-, Hm, I wonder whether that would work so well on the next barbecue...
[07:37] <smb> ppisati, Was ok for me, just the full backup that followed still runs...
[07:38] * smb wonders whether Bryan will make it back...
[07:40] <ppisati> seems Bryan has *a lot* of luck with airplanes lately... :)
[07:40] <ppisati> i know these words will condemn me to God knows what for *my* next travel anyway...
[07:41] <smb> ppisati, Probably. :) But yeah, birds, sick people... He works hard to become the next Colin... ;)
[07:52] <ppisati> "No space left on device"
[07:52] <ppisati> ARGHHHHHHHHHHHHHHHHHHHHH
[07:52] <RAOF> btrfs, or *actually* running out of space? :P
[08:02] <ppisati> the second one
[08:05] <smb> ppisati, You should not have downloaded so much p... err data... ;-P
[08:05] <jibel> is there a know issue with resume from suspend with kernel 3.5.0-5 ?
[08:06] <smb> jibel, I think we heard the one or the other curse a bit about it recently...
[08:07] <jibel> smb, should I file a bug or it's on the team's radar already ?
[08:09] <smb> jibel, A bug report in general would be good but maybe you can wait until apw gets conscious and ask him whether he already knows of one filed.
[08:17] <jibel> smb, ack, will do as soon as I can bring down my machine
[08:44] <apw> jibel, i don't know of a specific bug report as yet. cirtainly its affecting my travel laptop as well
[08:45] <apw> jibel, would "black screen on resume machine may be alive unsure" describe what you are seeing?
[08:45] <apw> thats what i am seeing about 3-4 resumes on -5.5, -4.4 was ok
[08:47] <jibel> apw, yes, it describes what I'm seeing.
[08:47] <jibel> and no reaction from keyboard e.g caps lock led
[09:10] <apw> jibel ok i have filed bug #1027828
[09:10] <ubot2> Launchpad bug 1027828 in linux "[Quantal] black screen on resume on 3.5.0-5.5 (regression from 3.5.0-4.4)" [Undecided,New] https://launchpad.net/bugs/1027828
[09:13] <jibel> apw, confirmed, thanks
[09:14] * apw seems to be able to hit it all the time, so hopefully we can find it pretty quick
[09:15] <apw> net: dont use __netdev_alloc_skb for bounce buffer
[09:15] <apw> smb, i see your net thing made it in for v3.5
[09:16] <smb> apw, yep
[09:17] <smb> apw, Just the scheduler thing still not pulled for right now
[09:34] * apw gets building some test kernels, why does resync home take soooo long
[09:39] * smb found it to be relatively quick... starts wondering whether all went back...
[09:39] * apw was more thining the mental sync back :)
[09:40] <smb> ah
[09:40] * smb probably is not back then
[09:41] <amitk> apw: I see those black screens on suspend too, with the latest from X-swat PPA
[09:42] <amitk> on precise
[09:43] <apw> amitk, what kernel is in there?
[09:44] <apw> my issue is definatly a regression -4.4 -> -5.5
[09:44] <amitk> apw: 3.5.0-5
[09:44] <apw> amitk, ok thats fine (and likely expected) then
[09:44] * apw has his suspicio
[09:45] * apw has his suspicions about a s/r fix that went in there
[09:45] <amitk> apw: so the quantal kernel on precise isn't really the latest quantal kernel? (sorry not running quantal yet)
[09:45] <apw> amitk, no it is the latest and thats where i am seeing this regression too
[09:46] <amitk> apw: the kernel makes resumes a _lot_ faster on macbook pro, when it does work
[09:47] <apw> amitk, interesting
[10:16] <cking> yawn
[10:21] <apw> cking, morning
[10:21] * cking notes that jet lag sucks
[10:22] <apw> cking, indeed so
[10:48] <brendand> cking, the fwts cpu_scaling test tests all the frequency governors, right?
[10:49] <cking> brendand, which specific test are you referring to?
[10:50] <cking> cpufreq?
[10:51] <brendand> cking, yeah - cpufreq would be the name of the test in fwts
[10:54] <cking> brendand, it basically figures out the set of CPU freqs available and steps through each one on each CPU. It does NOT test the different governors
[10:56] <brendand> cking, thanks
[11:32] * henrix is out for ~30mins (errands...)
[11:37] <apw> jibel, ok the latest 3.5 based kernel no longer reproduces the s/r hang for me, could you try the kernel at this url and see if it works for you too pls: http://people.canonical.com/~apw/lp1027828-quantal/
[11:37] <apw> (remember you need an -extra package too)
=== shadeslayer is now known as shadeslayer_
=== shadeslayer_ is now known as shadeslayer
=== yofel_ is now known as yofel
[12:59] <jjohansen> apw: haven't tried your kernel yet, but I built a 3.5 vanilla end of last week, and it fixed the s/r hangs for /me
[12:59] <apw> jjohansen, then i suspect mine will too
[12:59] <jjohansen> apw: yeah, I expect it will, I will test it in a bit
[13:08] <ogasawara> apw: sounds like we should squeeze in an upload for Alpha3
[13:08] <hggdh> please look at bug 1027524 - failure on QRT tests on omap-hf
[13:08] <ubot2> Launchpad bug 1027524 in linux-ti-omap4 "QRT failed on test_072_config_debug_rodata and test_072_strict_devmem" [Undecided,New] https://launchpad.net/bugs/1027524
=== shadeslayer is now known as shadeslayer_
=== shadeslayer_ is now known as shadeslayer
[13:36] <apw> ogasawara, yeah for me its a bit improvement over the -rc7 kernel
[13:37] <apw> if we can persuade jjohansen to test soonest then we can get the show on the road
[13:37] <ogasawara> apw: I've kick off some build tests in the mean time
[13:37] <apw> ogasawara, also i have pushed a 'tim did the rebase in on top'
[13:37] <ogasawara> apw: yep saw that, thanks
[13:38] <apw> ogasawara, if this does fix it for jjohansen as well then we should add that bug number to the rebase commit
[13:38] <ogasawara> apw: ack
[13:38] <apw> jibel, did you get to test that kernel at all? we would like to get some confirmations to justify an upload
[13:39] <ogasawara> apw: I am a little worried about the config vomit and firmware bits tim shoved in, so it would be good to get a little extra testing all around.
[13:39] <jibel> apw, oh, forgot to resume the mac, doing now
[13:39] <jibel> apw, it works
[13:40] <jibel> apw, any other verification you'd like me to do on this machine ?
[13:40] <apw> ogasawara, yeah am somewhat concerned about it all but if you are doing a bunch of config you want people to have tested after it
[13:40] <apw> jibel, well i found the issue was one in a few, so if you could do like 5 or so s/r's and just check
[13:40] <apw> jibel, i did 10 and seemed ok for me
[13:41] <jibel> ack
[13:41] <apw> jibel, other than that playing with it a little to see if its generally not pants
[13:53] <apw> smb, cking, if you have spare machines getting some testing on the kernels in http://people.canonical.com/~apw/lp1027828-quantal/ which is basically what ogasawara would upload
[13:54] <cking> apw, testing anything in particular?
[13:55] <ogasawara> apw: got any arm builds for ppisati? If not, mine should finish shortly.
[13:55] <smb> apw, I can get it into the acer relatively quickly (though it would be quite the same as yours)
[13:55] <smb> cking, I guess supend/resume
[13:55] <apw> cking, just as wide a set of "touch tests" machines wide as we can
[13:55] <smb> Not sure what is on the dell right now... lets see
[13:55] <apw> cking, as this has our config review hackery on top of it
[13:55] <cking> apw, ack
[13:55] <apw> ogasawara, no not done arm builds
[13:56] <ppisati> ogasawara: done this morning all arm builds
[13:56] <ppisati> ogasawara: i'm testing omap4 and is ok
[13:57] <ppisati> ogasawara: don't know about omap3
[13:57] <ppisati> ogasawara: asked ogra to give it a sping
[13:57] <ppisati> sping
[13:57] <ppisati> grr
[13:57] <ppisati> sping
[13:57] <ppisati> ARGH!
[13:57] <ppisati> spin!
[13:57] <ogasawara> hehe
[13:57] <ogasawara> ppisati: thanks :)
[13:57] * ogra_ spings
[13:58] <smb> ogra_, maybe spring? :)
[14:06] * cking thinks ppisati is suffering from jet lag
[14:07] <apw> cking, its hard to imagine anyone not, other than ogasawara of course
[14:07] <apw> though she will be kai-lagged
[14:09] <ogasawara> apw: heh indeed, I think I'll go refresh my cup of coffee
[14:16] * apw will be offline for a couple of hours, watching the torch
[14:23] <jibel> apw, resume failed at 7th try, but differently. Screen is white instead of black and the machine is alive. Likely an issue with screenlock or compiz, it looks like a stacking issue.
[14:45] <cking> apw, did 30 suspend/resumes OK on Lenovo x220i and a Ivybridge Intel SDP laptop, more results to come later
[14:51] <vanhoof> cking: on the new one?
[14:51] <vanhoof> cking: new sdp? :)
[14:51] <vanhoof> cking: if so, \o/
[14:52] <vanhoof> ;)
[15:06] * ogasawara back in 20
[15:47] <skaet> ogasawara, apw - any ETA on when we'll get the suspend/resume kernel fix uploaded? Anything else on the horizon kernel wise for A3?
[15:47] <pgraner> apw, any clue on this one? bug 1028004
[15:47] <ubot2> Launchpad bug 1028004 in linux "MMC Card Reader not working" [Undecided,New] https://launchpad.net/bugs/1028004
[15:47] <ogasawara> skaet: just waiting on a powerpc test build and then I plan to upload
[15:47] <ogasawara> skaet: probably another 2-3hrs.
=== cmagina-lunch is now known as cmagina
[15:52] <cking> apw, that kernel works on 30 s3 tests on a Dell 6400 and Atom based HP 210-1000 too
[15:53] <skaet> thanks ogasawara
[15:54] <ogasawara> skaet: just fyi, this upload will pull us up to v3.5 final as well
[15:56] <skaet> ogasawara, will we need a d-i update then as well?
[16:03] <ogasawara> skaet: yes, it is an ABI bump
[16:03] <ogasawara> skaet: I'm going to upload it to quantal-proposed, so you guys can ultimately make the call if you want to pull it in for A3
[16:15] <bjf> ppisati: can you look at bug 1027524?
[16:15] <ubot2> Launchpad bug 1027524 in linux-ti-omap4 "QRT failed on test_072_config_debug_rodata and test_072_strict_devmem" [Undecided,New] https://launchpad.net/bugs/1027524
[16:16] <ppisati> bjf: ack
[16:29] * ppisati -> gym
[16:32] <jjohansen> apw: so it didn't work for /me. It fixed the odd time out pause at the boot screen but the machine never came back from suspend. I tested it twice but have to admit I only waited a few minutes
[16:37] <cking> jjohansen, wait to see if it comes back after 300+ seconds (~5 + mins)
[16:39] <jjohansen> cking: I will give it another try in a minute, point being it didn't make the odd pause after resume go away for /me. Wanted to let apw know asap as they where considering it for and upload
[16:39] <cking> ack
[17:08] <infinity> bjf: https://bugs.launchpad.net/ubuntu/+source/linux-ec2/+bug/1021084 has been stalled for a week. Is cert testing not something that actually happens for linux-ec2?
[17:08] <ubot2> Ubuntu bug 1021084 in linux-ec2 "linux-ec2: 2.6.32-346.51 -proposed tracker" [Medium,In progress]
[17:12] <cking> apw, 30 more S3 tests passed on an AMD based Dell laptop and a UEFI Intel SDK box
[17:12] <bjf> infinity: looking
[17:13] <bjf> infinity: i didn't think we did cert testing
[17:13] <bjf> infinity: of ec2
[17:13] <bjf> infinity: marking it invalid
[17:14] <infinity> bjf: That would unstick it, yeah. Thanks. :)
[17:15] * henrix wonders why i didn't realised the -ec2 was still stuck
[17:16] <smb> cking, Hm, seems the aspire one stuck itself on some s3 cycle... Now that not necessarily means the kernel is bad...
[17:16] <bjf> henrix: i don't know if it is smart enought to detect that something is 'confirmed' for too long
[17:16] <cking> smb, that just means fwts s3 is good
[17:17] <smb> cking, And this netbook quite broken... :)
[17:17] <cking> smb, I'm doing a 32 bit install on a HPMini210 to see how well 32 bit works
[17:17] <henrix> bjf: well, at least we could detect something failed the 3 weeks cycle and fire an alarm
[17:18] <bjf> henrix: agreed
[17:19] <infinity> henrix: Or, you could rely on third parties to tell you! ;)
[17:19] <henrix> infinity: heh, right :)
[17:20] <smb> cking, Btw, I am sorry to report that fwts is not foolproof. It allowed the fool that is me to specify the --s3-multiple after the s3 argument without telling me that I am stupid... ;)
[17:21] <cking> ah, yeah, that's a problem indeed
[17:21] <jjohansen> cking, apw: test kernel didn't come back from suspend even after 15min
[17:21] <smb> cking, Oh well, one that sits in front of the screen.
[17:22] <jjohansen> apw: however the 3.5 vanilla that I tested earlier didn't either when I retested it
[18:26] * henrix reboots
[18:27] <apw> jjohansen, ok so i am going to call you an outlier, i think that is another issue
[18:28] <jjohansen> apw: yeah it seems so, I'll keep poking at it
[18:33] <smb> apw, My Acer also seems to suffer of something else. It failed the fwts s3 tests after 7 and 12 repeats but with a black screen, the dell was ok
[18:47] <cking> apw, my HPMini210 in amd64 and i386 can do S3 x 30 successfuly
[18:58] <ogasawara> apw: still want me to shove 1027828 in the changelog to get autoclosed?
[19:57] <bjf> cking: bug 1028111

[19:58] <cking> bjf, ack, will look at that first thing tomorrow, probably a test failure rather than a kernel bug, but I will poke it tomorrow
[19:58] <bjf> cking: thanks
[20:06] * smb -> eod
[20:09] * cking -> eod too
[20:43] <apw> ogasawara, i'd say yes. i say my problem is fixed
[20:43] <ogasawara> apw: cool, I'd had the same train of thought so I shoved it in and uploaded
[20:44] <apw> ogasawara, excellent. clearly we have other issues, but those are bad
