sbeattiebjf: if you look at http://kernel.ubuntu.com/testing/dagmar__3.13.0-53.89__2015-05-20_21-43-00/console_output.txt.html you'll see apt-get update pulling trusty, trusty-security, and trusty-updates Sources, but not for trusty-proposed.06:15
sbeattiewhich tells me that there's no deb-src line in apt sources.list for trusty-proposed.06:16
pkerninfinity: Thanks. I'll have a look this morning.06:25
henrixpkern: please let me know too if that kernel looks ok ;)07:40
genkgojsalisbury: that new build is doing better07:56
genkgojsalisbury: could tools was installed, but to install tools, i need binutils >= 2.2507:57
genkgoi am still on 2.24 (i guess because i am on trusty with 3.19 kernel)07:58
genkgoperhaps i can still with --ignore-depends07:58
genkgojsalisbury: just ran sudo dpkg --ignore-depends=binutils -i linux-tools-3.19.0-18*.deb and the package was installed08:02
genkgoapw: could you confirm that it is alright to ignore binutils dependency in this case?08:02
apwgenkgo, i think you should be ok indeed08:02
=== shuduo is now known as shuduo_afk
genkgoapw: well wonderful, then i can start testing the patches08:03
genkgo:)08:03
infinitypkern: As soon as you can get me some positive "yay, it fixes the bug" results on that trusty kernel, I can unleash it on the masses.08:23
nilujewhat's the difference between the UIO and the VFIO drivers?08:41
pkerninfinity: Yeah, I'm in the office now to test. :)09:13
infinitypkern: \o/09:13
infinitypkern: Looks like we'll just barely make my 24h turnaround guess, then. :)09:14
pkerninfinity: lgtm, thanks :)09:23
pkernhenrix: ^^09:23
henrixpkern: ack, thanks!09:24
infinitypkern: Ta.  Releasing them all, then.09:25

cykinggood morning!15:09
cyking3.19.0-18-generic botched my AMD video driver (fglrx)16:15
apwcyking, what version did it work with before that ...16:27
apwcyking, and ... what does "botched" mean to you16:28
cykingchecking,16:28
cykingLinux Main-PC 3.19.0-031900-generic16:29
apwcyking, ok that is a mainline kernel, did it work with any of our official kernels16:31
cykingapw: yes -worked with the last official kernel16:31
apwcyking, which is the last one you actually tested, which version number16:32
apwas -17.17 and -18.18 are mostly identical in the video arena iirc16:32
cykingall these kernels worked - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1453391  16:32
ubot5Launchpad bug 1453391 in linux (Ubuntu) "Very slow Qualcomm Atheros AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0)" [Medium,Confirmed]16:32
cykingchecking my /var/log/apt  I believe it was linux-image-extra-3.19.0-16-generic16:35
apwok, so that is more believeable as there are actully some changes from -16 to -1816:35
apwcyking, now can you describe botched for me16:35
cykingapw: i get the radeon driver instead of the fglrx driver.  and radeon doesn't let me work with multiple displays.16:37
apwdid fgrlx build against -18 for you ?16:38
cykingapw, i really just did a gui update and did not have any errors.  is there a log i can check for you?16:39
cykingdoes help:  /var/log/apt:  http://pastebin.com/bea9Ck6a16:42
apwcyking, there is a log in /var/lib/dkms, like here i have this for nvidia dkms package i happen to have installed: /var/lib/dkms/nvidia-340-updates/340.76/3.19.0-16-generic/x86_64/log/make.log16:43
apwobviously subsitute in the versions you have installed of radeon16:45
cykingapw, http://pastebin.com/7VEixiZn16:46
apwcyking, so that seemed to build ok, if that was the right kernel version16:47
apw/var/lib/dkms/nvidia-340-updates/340.76/3.19.0-16-generic/x86_64/log/make.log16:47
apwgrrr16:47
apwso16:48
apwDKMS make.log for fglrx-updates-core-15.200 for kernel 3.19.0-16-generic (x86_64)16:48
apwthat is the log for -16 which worked we want the one for -1816:48
cykingapw: should i boot into -18 and try to force reinstall the dkms driver?16:50
cykingthere is no log for -1816:56
apwcyking, can you list the packages with 3.19.0-18.18 in their version ...16:57
apwdpkg -l | grep 3.19.0-1816:57
cykinghttp://pastebin.com/J0ZT5TZX16:58
apwcyking, you don't have the headers installed for that kernel, so dkms cannot build fo rit16:59
apwcyking, do you have the right meta package installed for the kernel?  linux-generic ?17:00
cykingstrange. if i have linux-headers-3.19.0-16-generic and linux-headers-3.19.0-16 installed wouldnt apt-get update automatically install the latest?17:00
cyking*dist-upgrade17:00
apwcyking, headers are pulled in by linux-headers-generic17:01
apwwhihc is a dep of linux-generic17:01
apwi assume you have lost some of your meta packages somewhere along the line17:01
cykingthanks apw: installing now. must of gotten removed accidental with all my kernel testing with my other bug im trying to deal with.17:02
apwcyking, very likely it got removed when you jammed something else on, apt loves to do that for you17:03
apwand although it is right there in front of you, i find one never notices it17:03
cykinghow do i rebuild now ?17:04
apwshoving the headers on should trigger the dkms build automatically17:04
apwyou should see it in the output when you apt-get install linux-generic or whatever17:05
cykingis it doing it here:   run-parts: executing /etc/kernel/header_postinst.d/dkms 3.19.0-18-generic /boot/vmlinuz-3.19.0-18-generic17:05
cykingi see the  log now. thanks17:06
apwthat looks believeable, once you get a prompt back you should be able to see the log17:06
apwso then a reboot should use that driver i'd say17:06
cykingis there an idiots guide on doing a kernel bisect ?  17:06
apwthere is a wiki guide, but i normally ask joe, he is a bisect speciialist17:07
apwjsalisbury, ^17:07
cykingjsalisbury seems pretty busy :)17:08
cykingi use to kernel hack in 2.4 days but so much has changed.17:08
jsalisburycyking, I actually started a bisect for your bug17:08
cykingjsalisbury, thanks17:09
jsalisburycyking, there was a build failure so I had to skip some sha1s.  I should have a kernel ready soon17:09
jsalisburycking, actually the next kernel is ready.  I'll upload it and post a link in the bug17:10
cykingjsalisbury, you are a star!17:10
jsalisbury:-)17:10
cykingand you too, awp, thanks17:10
cykingjsalisbury, ill install the *rc3.201505211629_all.deb ?17:16
jsalisburycyking, You should just need: linux-image-3.13.0-031300rc3-generic_3.13.0-031300rc3.201505211629_amd64.deb17:17
jsalisburycyking, just run: sudo dpkg -i linux-image-3.13.0-031300rc3-generic_3.13.0-031300rc3.201505211629_amd64.deb17:18
jsalisburycyking, then reboot17:18
cykingyup understood17:19
cykingsudo make internet faster ?17:19
cyking;)17:19
jsalisburyheh17:20
cykingjsalisbury, worked fine.17:39
jsalisburycyking, great.  I'll update the bisect and build the next kernel17:44
cykingwish i could see a screen cast of what you were doing ;)17:45

bjfsbeattie, i think the trusty apparmor testing is fixed18:17
bjfsbeattie, it worked once :-) ... we'll see for sure next week (new kernel SRU cycle)18:18
sbeattiebjf: hehe18:19
sbeattiebjf: the trusty apparmor sru should fix https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1304447 so please do comment on that bug report18:21

dsmythiesSomewhere between kernel 4.0 and kernel 4.1RC1 "perf record" became broken. Actually the list of available "Tracepoint event"s become very much smaller. My concern is with "power:pstate_sample", which is now missing. I have started to bisect the kernel, but thought to ask here also, as I really don't have 2 days to waste. Anybody know what is going on with this?19:06
rtgdsmythies, are you booting vanilla or ubuntu kernels ? ubuntu does carry some ftrace patches.19:10
dsmythiesI only compile the mainline kernel, using the Ubuntu kernel config.19:11
rtgdsmythies, nothing springs to mind.19:12
dsmythiesI'll continue my bisection (my second one for the 4.1RC series...)19:13

nessitajsalisbury, hi there, are you around?20:16
nessitajsalisbury, just wanted to sync about the bisect we're doing for LP: #1201528, since I'm now in 3.8.13.1 and audio died with the underrun error. So I re-read all the comments and noticed that in commnet #39 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1201528/comments/39) I reproduced the issue with kernel 3.8.0-27-generic20:20
ubot5Launchpad bug 1201528 in linux (Ubuntu Vivid) "[INTEL DP55WG,Realtek ALC889] - Audio Playback Unavailable" [Medium,Confirmed]20:20
nessitaI'm now installing latest 3.7 from http://kernel.ubuntu.com/~kernel-ppa/mainline/ which is 3.7.10 and see if audio breaks, will report in the bug20:21
jsalisburynessita, ack, thanks for the info20:54
nessitajsalisbury, so 3.7.10 works (used skype heavily, and hangouts), and in theory 3.8.0 did not work (from comment #39). Which kernel shall I try next?20:55
nessitawant me to re-test 3.8.0? I guess that'll be v3.8-raring?20:56
jsalisburynessita, probably 3.7 final, then we can bisect between 3.7 and 3.8.  3.7 final is avaiable at:20:56
jsalisburyhttp://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-raring/20:56
jsalisburynessita, it might be a good idea to test 3.8 final as well to confirm it has the bug.  3.8 final is avaiable at:20:56
jsalisburyhttp://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/20:57
nessitajsalisbury, ah, hum, I always thought that 3.7.0 (from the link you just gave me) is "older" than 3.7.10. Am I mistaken? 20:57
jsalisburynessita, yes you are correct.  But we can't bisect between 3.7.10 and 3.8 because the tree splits as of 3.7.1.  20:58
nessitaah! that makes more sense :-)20:58
nessitaI will them test both finals, 3.7.0 and 3.8.0 and report back20:58
nessitajsalisbury, kernel 3.7.0 is frozen on boot when showing the message "Loading initial ramdisk", can not reboot with ctrl+alt+del nor with alt+petsys+b, doing hard reboot, but wondering if it should boot OK21:14
jsalisburynessita, it should boot ok.  We can skip to trying v3.8-rc1 if there are issues with 3.7 final.  3.8-rc1 is available here:21:15
jsalisburyhttp://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc1-raring/21:15
nessitajsalisbury, hum, there may be something broken in my computer now, because 3.8.0 freezes the same as 3.7.021:16
nessitamay boot without quiet and see where it freezes21:16
jsalisburynessita, ok21:16
