apwjjohansen, morning, hows it going today08:53
jjohansenheh, not bad, at least not yet we will see how the night goes :)08:54
smbIt should be dark, quiet and you probabaly sleeping. :)08:54
apwjjohansen, heh out of sync as usual i see08:58

=== jjohansen1 is now known as jjohansen
apwjjohansen, you are tired!  time for bed09:03
jjohansenapw: hehe, no I'm really not.  The terminal had been connected to the test box, but it was one that had dropped.09:05
tumbleweedhi. anyone know the state of core i3 (intel hd) graphics on lucid? Got a new box that'll boot with a Maverick kernel, but not lucid.09:05
jjohansenI know because all the terminals in that workspace were09:05
smbipmitool -Ilanplus -Hjjohansen power off09:05
jjohansenhrmm, if only /me could take a hint :)09:06
apwheh09:06
jjohansentumbleweed: where does the boot fail09:06
apwipmitool -Ilanplus -Hjj-house power off09:06
apwipmitool -Ilanplus -Hjj-state power off09:07
smbapw, I guess we would have to add a -Uspouse09:07
jjohansenaw shucks my ups lasts about 1 min09:07
tumbleweedjjohansen: kernel BUGs... http://paste.ubuntu.com/581502/09:07
tumbleweedoh, whoops, multiple boots in there09:08
jjohansenapw, smb don't worry I won't be here all night, but I need a few hours to settle down from exercising09:08

apwindeed, the kernel hates your BIOS with a pasion09:10
tumbleweedheh09:10
tumbleweedI'll try a static share rather than "auto"09:11
apwsmb, i have just realised that 5 years at an abi bump every 2 weeks (worst case) will bust the 0-99 range we have for abi on lucid master09:12
jjohansenapw: are we doing an abi bump every time?09:13
jjohansenyes /me knows they have been changing, just whether we expect them to always change09:14
apwjjohansen, well they tend to pretty often, its not 100% guarenteed of course but worst, worst case we can double bump in a 2 week period due to reverts ... so i still think we'll be pressing in on 99 09:16
apwmight be prudent to increase spacing for natty and above09:16
jjohansenoh yikes /me wasn't thinking of double bumps09:16
jjohansendefinitely09:16
tumbleweedapw: thanks reducing it to 128M did the trick. /me kicks himself for not following the suggestions from the kernel first09:18
apwtumbleweed, hrm, not sure that that isn't a bug however ... the rest boots ok now?09:18
tumbleweedapw: yeah09:19
tumbleweedit cerntainly works out the box with the maverick kernel, so the issue has been fixed / worked around09:20
apwahh good point09:21
smbapw, jjohansen I guess worst case we will have to to a magic bump into the higher regions09:22
apwsmb, yeah probabally so09:24
* apw reboots to test a patch09:24
apw(this is my only affected work station, of course)09:24
smbFarewell friend...09:25
smbapw, Successful?09:29
apwit boots at least09:29
apwso far seems to suppress the terminal corruption i was seeing too09:37
smbsounds not too bad then09:38
smbapw, Was that the sort of corruption that suddenly would garble the contents of your window but go away when you scrolled or refreshed?09:38
smbvi09:39
apwsmb, yeah thats the one, though the commit is really expected to make it better not worse09:40
smbapw, sounds like the thing I noticed somewhat on my aspire one. Though I usually put it to bad hw09:42
apwyeah, if you look close its 'previous screen contents' dithered and mixed with the current screen09:42
jjohansenapw: does that happen to you in other windows than a terminal, that bug seems to hit pigin, chromium, and mumble for me09:43
jjohansenor perhaps its just a bug that is similar09:44
apwjjohansen, i cannot say i have ever seen it anywhere else, but the bug is in copy operations on areas of screen not particularly text related09:44
apwi rarely scroll anything but terminals and chrome09:45
jjohansensounds like it09:45
jjohansenhrmm, but I see corruption without scrolling09:45
jjohansenbut perhaps its because of switching workspaces09:46
tumbleweedapw: ah, you ran into the same corruption bug I reported. I see it most in curses programs, but scrolling is a sure way to trigger it too.09:59
tumbleweedI've very occosionally seen corruption in other windows (often notfy-osd), but that may be unrelated10:00
jjohansentumbleweed: now that you mention it I do usually see the corruption in other window under where notifications displayed10:02
apwtumbleweed, yeah am trying to debug it now, its very annoying, upstream has offered some things to try10:02
apwtumbleweed, i may have a fix for that corruption bug, i will be pushing some kernels for testing shortly; are you able to test?10:28
tumbleweedapw: certainly10:30
apwbe about half hour, i'll poke you when they are up10:30

Ntemisfinally i have found the sweet spot on my server12:14
Ntemisall kernels <2.6.38 where freezing my system randomly because of my eth0 r816912:15
Ntemiswith 2.6.38 problem seems gone :)12:15
Ntemisthanks guys12:16
Ntemisfor the mainline repo12:16
Ntemisbtw is a 8111E realtek12:16
apwthere was something for r8169 very recently12:17
Ntemishi apw12:17
Ntemisi was here before some days posting my kernel logs12:17
Ntemisyou remember me?12:17
Ntemisnothing found on the logs12:17
apwseems it was in -rc812:18
Ntemisseems the caveat was my 8111E gbit lan 12:18
Ntemisit was freezing the server randomly12:18
Ntemisno ssh access12:19
Ntemiswhy they remove the firmware from 8111D? from 2.6.3812:19
apwcirtianly the latest have some fixes for ASPM killing r8169's dead and nothing in the logs12:19
apwNtemis, not sure i saw them removing firmware, though most migrates into the firmware package when pulled out12:19
Ntemisthat one was in the 2.6.37.4 but server still freezed12:20
Ntemisis not the aspm the problem12:20
Ntemisproblem gone for good on 2.6.3812:21
Ntemissomething else changed on r8169 driver12:21
Ntemisi thing they got the realtek driver and used some code from it12:21
Ntemisport it over12:21

tgardnerapw, I just updated the tangerine natty schroots. have a look at the gcc segfaults in dmesg.13:25
apwtgardner, no not more compiler fallout ... bloody hell13:26
apwtgardner, are they all since you updated ?13:26
tgardnerapw, can't tell when they happened. looking in syslog...13:26
apwtgardner, i'll bang a build in and see if we get some more13:27
tgardnerapw, hmm, not showing up in syslog. I was hoping time would be normalized with the segfault message13:27
tgardnerapw, bang away13:28
apwtgardner, i386 builds don't seem to be triggering it13:48
tumbleweedapw: I'm not seeing any corruption yet13:49

apwtumbleweed, i don't seem to be able to reproduce your other corruption in unjity there... can't tell if thats unity or the same sort of bug ... unity being a little volatile14:23
apwtumbleweed, would you agree its a major improvement?14:23

tumbleweedsorry just sorting out stuff for a meeting I'll comment on bugs in an hour and a bit14:25
jcrigbyapw, tgardner: quick question,  I've been asked to turn on CONFIG_PNP_IP in linux-linaro-omap to allow setting ip config on command line.14:25
jcrigbyall the other linaro flavours all ready have it on because their configs came from kernel source defconfigs14:25
jcrigbybut omap came originally from ubuntu kernel14:26
apwjcrigby, those are totally separate from our omap arn't they?14:26
jcrigbyapw, yes just drawing on your wisdom14:27
* apw can't even find such an option in natty14:27
apwor maverick or lucid14:27
jcrigbyI may have spelled it wrong14:27
jcrigbyCONFIG_IP_PNP14:28
jcrigbyCONFIG_IP_PNP and CONFIG_ROOT_NFS are very useful for embedded development14:29
apwthey don't sound like dangerous things to enable to me14:29
jcrigbyok, just checking if there was some historical or other reason, thanks14:29
tumbleweedyay just caused a total lockup by running impressive (GL)14:30
apwjcrigby, the description implies they are only needed for your kind of use case, so i can see why they would be off in our world14:30
jcrigbyright14:30
tgardnerapw, I think CONFIG_IP_PNP could cause unhappy things. I'm concerned about the connection table getting populated  with stuff you may not necessarily want.14:33
apwtgardner, yeah cirtianly wasn't proposing we enable it in any of our images14:33
tgardnerapw, upgraded from maverick to natty on the HP mini. seems to have gone pretty well.14:49
apwtgardner, yeah we are past the absolute worst of unity cratering every 10s14:53
apwi am using it here on this netbook without whining14:53
apwnow that most things seem to work i am working up to upgrading on my dekstop14:53
tgardnerapw, gsettings-data-convert crashed a couple of times, but now seems to have stopped.14:54

apwkamal, yes it is ready for it, but i didn't have one at hand or the time to ensure it was the right one before, as i had to hit betweeen two compiler uploads16:10
apwkamal, is it somehow causing a problem?16:10
kamalapw: not at all!16:10
kamalapw: just makes PPA uploads take forever and consume more PPA space -- not at all critical.16:11
tgardnerkamal, it goes fast from tangerine16:12
kamaltgardner: yup, sure does :-)16:12
apwkamal, or from zinc16:12
kamalapw, tgardner: I do all my own test builds on tangerine, but I upload (the fully tarball, in absence of a .orig) to PPA to publish16:13
apwkamal, as do i, but push the branch to zinc and package it there, and upload it from there16:14
kamalapw: ah yes, I just clued in to what you guys meant there.16:14
apwkamal, anyhow, it will have one shortly, as i have to reupload for the next comp change16:14
