BenCsconklin: I thought I had verified that patch already02:11
chadhoggjjohansen: I was unable to boot with the kernel you built me; details on launchpad02:28
twbStupid question: why does lucid-backports have linux kernels up to .35, but e.g. "compat wireless" modules up to .38?05:28
twbOh, I see, it looks like it's the driver taken from the .38 tree and compiled against .3205:29

diwicapw, before my vacation I traced down a bug in PulseAudio that could be a gcc bug. Do you know how to proceed with that?08:25
apwdiwic, normally one would file a bug against gcc, they will want the minimum code fragment that causes the miss-compile and a good description of how it is miss compiled08:26
apwagainst gcc-4.5 or whatever i guess08:27
apwhow do we know it is a compiler problem ?08:27
twbapw: problem goes away when you change the compiler08:27
apwas unfortuanatly code which is relying on undefined side effects of some code forms can then change if you change the compiler08:27
jjohansentwb: all other parts of the environment the same?08:28
apwtwb, one would really want to find the exact bit of code whihch is being miss built08:28
diwicapw, is bug 789031 filed against the right package?08:28
ubot2Launchpad bug 789031 in gcc-defaults "Built-in ASM constraint "rm" does not work" [Undecided,New] https://launchpad.net/bugs/78903108:28
twbapw: granted08:28
apwdiwic now that even sounds familiar, i wonder if something in the kernel ht the same issue08:29
apwdiwic, i think i'd expect it to be gc-4.5 or gcc-4.6 depending on the version you are using08:29
diwicapw, actually in pulseaudio the problem was worse, it allocated one "r" and one "rm" into the same register08:30
diwicapw, but I couldn't get that done to a simple example08:31
apwso i think other than i think you want to do the right version, it looks good.  i would poke doko so he is aware, he is likely to recognise it if its come by already as a fix08:31

jazz2hi, I upgraded my server from 9.04 to 10.04 (via 9.10); the server is connected in my lan via wlan(wpa2); ...10:29
jazz2the problem now is that the speed downloading from the server to the lan is down from ~700kb to ~100kb, while uploading to it is mostly not affected (~700kB). ...10:29
jazz2I tried: 10:29
jazz2a) using a wired lan connection->normal speed, 10:29
jazz2b) booting with kernel 2.6.28-19-generic -> wlan speeds are back to normal 10:29
jazz2c) booting with kernel 2.6.31-14-generic -> wlan speeds still degraded10:29
jazz2question now is: what changed between the kernels and where do I start to fix this? any help would be highly appreciated10:29

sconklinsmb: your comment in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/681083 - sorry I'm not up on all the virt stuff - does his test imply that the bug has been fixed in the XenMotion case, or only that the kernel doesn't fail in a major way?14:54
ubot2Ubuntu bug 681083 in linux "Ubuntu Crashes/Freeze on XenMotion" [Medium,In progress]14:54
smbsconklin, Whatever they exactly do in xenmotion I actually do not know. But one part is running generic kernels (-pae in i386) as domU guests.14:56
smbSo when he took that 2.6.35 kernel I provided and installed it into his Lucid guest, the Maverick kernel got tested14:56
smbsconklin, Probably another argument could be that this patch is now added for the next 2.6.32 (may or may not get picked for .35 as well) longterm tree14:57
smbSo sooner or later it will come. But I heard you are slightly frustrated by longterm trees. :)14:58
sconklinBenC: I see your test results in the bug - It's that the SRU process requires that someone actually test the kernel in -proposed, and it looks like you tested a test build to validate the patch.15:02
BenCsconklin: Ok, I'll test the actual build15:03
sconklinthanks, much appreciated15:03

BenCsconklin: Ok, confirmed...where do I add my two-cents?15:35

jjohansenapw: tangerine seems to be hanging on builds (not just in schroots), who do we hit up to look into it17:45
apwjjohansen, whats the symptoms17:46
apwcnd what you doing to tangerine?17:46
sforsheeapw, fakeroot is hanging in the kernel trying to get some semaphore17:46
jjohansenapw: it just hangs, sforshee reported and I duplicated17:46
apwsforshee, anything specific, which sema ?17:47
sforsheeapw, not sure17:47
apwi can bounce it if thats useful17:47
sforsheeyou'll see a bunch of faked-sysv processes in uninterruptible sleep17:47
sforshee/proc/<pid>/wchan shows call_rwsem_down_write_failed17:48
sforsheeapw, yeah it prolly needs to be bounced when cnd is done17:48
apwok well let me know when he is done, if he can be anythiong other than done17:49
apwsforshee, given its actual makes which are spinning, i'd say he is not making progress17:49
apwyeah they are dead i recon17:50
apwsforshee, i don;'t think cnd is making progress17:53
apwvotes for bouncing ??17:53

SpecialistHi there, are there any plans to publish a kernel update for natty based on a recent -stable (> 2.6.38.6) kernel version?21:41
SpecialistI am asking because I am affected by bug #746860, which has already been fixed upstream21:43
ubot2Launchpad bug 746860 in linux "System sporadically freezes during suspend to RAM" [Undecided,Confirmed] https://launchpad.net/bugs/74686021:43
sconklinSpecialist: the natty kernel currently in -proposed is current thru 2.6.38.8 but has two known regressions that we will have to resolve before we can fix it and spin another release21:49
sconklinhttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/792013 is the tracking bug for that, and has other bugs linked from there for the regressions21:50
ubot2Ubuntu bug 792013 in linux "[Regression] linux: 2.6.38-10.44 -proposed tracker" [Medium,In progress]21:50
Specialistsconklin: thanks! i'll see whether those affect me and will probably just take the kernel from -proposed if they don't21:50
sconklinSpecialist: if either of them affect you in a way you can reproduce, we could use help bisecting kernels to locate the problem. I think our main reporter is gone until Monday . . .21:52
vanhoofsconklin: ah cool, I didn't know -10 in -proposed carried all the way through 2.6.38.821:53
sconklinSpecialist: sorry, I got that wrong. The release in -proposed has up through 2.6.38.721:53
* vanhoof has a few bugs that will get closed out then :)21:53
vanhoofah rats :D21:53
sconklinwe've temporarily stopped taking upstream updates because of the load of regressions we got in the last batch21:54
sconklinvanhoof: anything you really care about, open an SRU bug even though it's in a stable update, and get it on the kernel list for acks.21:55
Specialistsconklin: np, as long as it's > .6, it's fine ;-) i'll let you know if i see anything unusual comparable to the two regressions with the -proposed version21:55
Specialistsconklin: is the bisect progress documented somewhere?21:55
sconklinvanhoof: sorry to push things into that path, but we're trying not to take another multi-week train wreck21:55
sconklinSpecialist: hold in - herton has been doing those ^^21:56
vanhoofsconklin: well .8 will make its way in at some point21:57
hertonSpecialist: for bug 793796, the bisect progress is on last comment on bug report21:59

hertonit's waiting for the reporter to test the next step22:00
hertonthe other one (bug 794096) is on a bisect also with the reporter, he will only be able to test next bisect next week...22:01
ubot2Launchpad bug 794096 in linux "SMTP and posting to a web-form time out (probably due to netfilter changes)" [Undecided,In progress] https://launchpad.net/bugs/79409622:01
hertonthis last one is weird, as reporter already tested with the most likely changes which could cause the issue reverted22:02
hertonand there isn't much info yet which could point to real issue22:03
hertonI tried to reproduce both here but without success, so if there is anyone else being able to reproduce the same and able to help would be great22:04
Kanohi, which config option is the problematic one that now a newer module-init-tools is required22:58
Kanorc2 worked fine with lenny, rc3 does not22:59
Kanobut even with squeeze 3.0rc3 works,so you do not need that extreme depend23:00
Kanoi lower it in my install scripts anyway23:00
Kanothis just takes useless time23:00
apwKano, its there becase we need it in the oneiric tree where the versions are correctly specified, and its getting copied to the mainline builds.  i'll fix it when i have time23:58
apwas you have noted you can actually fix it yourself as you make your own packages23:59
Kanono i use dpkg-deb23:59
