cjwatsonCould somebody look at bug 709694?  It's RC for 10.04.212:04
ubot2Launchpad bug 709694 in linux-backports-modules-2.6.32 "Lucid package linux-backports-modules-wireless-lucid-generic broken" [Critical,Triaged] https://launchpad.net/bugs/70969412:04
cjwatsonand it's effectively a regression in lucid-updates12:04

apwcjwatson, looking12:18
apwcjwatson, it looks to me that it was built (in the canonical-kernel-team PPA with the kernel) but was missed with the pocket copy12:22
apwcjwatson, i believe that the version in the canonical-kernel-team PPA is the one intended to complete the -28 set, i am unsure as to why it was not pocket-copied with the kernel meta etc12:38
cjwatsonapw: so I should do that?12:39
apwcjwatson, i suspect so yes, i was just closing the loop with pitti to see if he has information12:40
cjwatsonack12:40
apwsmb, about ? 12:49
smbapw, Just came back12:49
apwsmb, most handy :)  you have some lucid systems still i think?12:50
smbapw, One or the other.12:50
ohsixapw: cgroup-bin was breaking suspend12:54
apwsmb, thanks for that12:54
apwcgroup-bin ?12:54
ohsixthe package, it has configs & a daemon to move things into cgroups12:55
ohsixsome kernel threads didn't like that when there were no resources in the group to get their job done12:55
apwohsix, oh, hrm ... interesting ... so lets get a bug files against that, or your existing bug opened out to that a well ...12:55
apwohsix, that does at least explain why you are one of the few hitting it12:56
ohsixi'd had it installed for a few months to poke at it; that was enough to break stuff12:57
apwtgardner, didn't seem you had the x35 (3873) cve assigned to you in the sheet ... added14:12
tgardnerapw, huh. thanks14:18

Kanohi apw , did you get my message about RTL8192CE firmware?14:55
apwKano, i saw it mentioned yes.  we may have rebased on upstream firmware base since then14:56
apwi have not explicitly checked it is in there14:56
apwdpkg-buildpackage -S -rfakeroot -I.bzr -I.bzr-builddeb -I.git -I.gitignore -i'\.git.*'15:00
apwsconklin, ^^15:00
Kanoalso the rt8192se driver is crap15:01
Kanobasically it is in the kernel directly but does not work15:01
Kanoso you have just got 2 non working drivers15:01
Kanothe .32 kernel driver version sometimes worked15:02
Kanobest works ndiswrapper...15:02
apwKano, realtek has a questionable track record with open source drivers, indeed15:03
apwwe tend to rely on backports modules for those, and much finger crossing15:03
Kanobut they dont work15:03
maks_it's crap hardware too.15:04
Kanofee free to send me a minipci card with something better15:05
maks_vorlon has a funny post about getting rid of it.15:06
Kanowell ndiswrapper is ok but...15:07
Kanowhy is the native driver not working15:07
Kanomaybe you could get testhardware *g*15:07
Kanolike samsung n51015:07
apwKano, i personally tend to stay the heck away from anything which has rtl in it, just too hard15:12
Kanoprism 54 softmac is not better, i have got those cards too15:15
Kanodoes never work with 64 bit15:15
Kanosomehow i only get non working cards15:15
Kanoand there is not even a win 64 bit driver, at least i did not find one. for 32 bit ndiswrapper would work too,but native work there15:21
tgardnersconklin, just uploaded linux-meta 2.6.32.29.34 to the c-k-t PPA to enable compat-wireless 2.6.3715:22
tgardnersconklin, you should roll the ABI on everything else in Lucid and get them uploaded.15:23
sconklintgardner: Aye. Is this an exception to the current freeze?15:23
tgardnerno, this is going into your c-k-t PPA, not the archive.15:24
sconklintgardner: yeah, I just wanted to know how much of a hurry there was15:24
tgardnersconklin, well, I think you should have _all_ the ABI dependent packages consistent lest we miss getting one of them copied.15:25
tgardneryou --> we15:25

hallynhm.  this is gonna really screw up my week :)16:06
hallynsuppose tmobile coudl be messing with me, but seems unlikely16:06
hallynok, thanks, i'll start tracing16:06
Kanoapw: btw. you are right, the firmware is in rtlwifi dir, i used an older driver..16:08
cndsconklin, thanks for the heads up on the w3c touch stuff :)16:14
cndI just reviewed it and have some comments for him16:14
sconklinDoug is a really nice guy, would welcome contact. He'll be at LGM in Montreal, I'm pretty sure16:15
cndLGM?16:17
Kanoapw: just one thing, why does the r8192ce_pci module has got this extra id: pci:v000010ECd0000092Dsv*sd*bc*sc*i*16:19
sforsheecnd, are you very familiar with the ntrig digitizer?16:19
cndsforshee, sadly, yes...16:19
Kanoand the rtl8192ce module from kernel .38 not16:20
sforsheecnd, i could use some debugging tips if you have any16:20
cndsforshee, what's wrong?16:20
sforsheei have a dell latitude xt2 where the pointer jumps around and clicks all the time16:20
sforsheei've had to blacklist the driver just to make it usable16:20
sforsheehid_ntrig, that is16:20
sforsheeit's spewing out multitouch events constantly16:21
bjfhttp://www.zdnet.com/blog/btl/intel-hit-with-chipset-design-flaw-in-sandy-bridge-rollout/4425716:21
cndsforshee, hah, yeah, that's ntrig for you16:21
cndyou can try calibrating it16:21
cndthat should help16:21
cndlet me get you the link16:21
sforsheecnd, thanks, i'll give it a try16:21
cndhttps://wiki.ubuntu.com/Multitouch/Calibration/Ntrig16:21
cndsforshee, I have the same problem on my dell studio 17 with ntrig16:22
cndit's what I use for my MT development16:22
sforsheecnd, I saw your name in the driver changelog, so I thought I'd hit you up :)16:23
cndyeah... though most of the work was done by henrik rydberg16:23
cndwho no longer is with us16:23
cndand probably never wants to touch that driver again16:24
cndI think it's going to be a festering sore spot for us until ntrig hw is so old that we can just forget about it16:24
manjotgardner, are you suggesting this package ? linux-backports-modules-net-maverick-server16:25
sforsheecnd, getting build errors for undefined references to usb functions, is some library needed besides libusb-dev?16:26
cndsforshee, maybe, alas this isn't my code either...16:26
sforsheecnd, okay, I'll work on figuring it out16:27
tgardnermanjo, no, I'm suggesting linux-image-server-lts-backport-maverick16:30
manjotgardner, ack will ask them if that works 16:31
sforsheecnd, everything's installed, and I got the build working by manually adding libusb.a in the makefile instead of -lusb, not sure though why -lusb isn't working16:38
sforsheebut calibrating did fix the problems16:38
sforsheethanks for the  help16:38

smbapw, btw, TRANSPARENT_HUGEPAGE selects COMPACTION and that MIGRATION. wibble17:02

cndsforshee, good to hear :)17:12
cndwe should probably package that up...17:12
sforsheecnd, it's a hack, i hard-coded the include path17:12
sforsheeit would be nice to find a better solution17:12
cndyeah17:13
sforsheethe lib path rather17:13
sforsheewhen I get a few minutes I'll see if I can find something better17:13
cndwell, the whole thing too :)17:13
cnda big hack17:13
sforsheeI'm wondering if there's another libusb somewhere that's getting pulled in instead, because there's no error about not finding the lib, just about unresolved symbols17:14

JFoyep, komputes, I need the apport-collected data  18:15
JFonot sure if there was anything else that apw mentioned wanting18:15
komputesJFo: that hasn't been collected by opening the bug - apw mantionned that laptopdetect had to be run as sudo, which was done - result being it's detected as a laptop, yet still no battery status18:16
komputesJFo: you want apport collect info for the kernel18:17
JFothe first bit there didn't make much sense to me "that hasn't been collected by opening the bug" Correct, that hasn't been collected. unless you meant something else. :)18:17
JFoI do :)18:17
apwkomputes, so we do think it is a laptop18:19
komputesapw: indeed18:19
komputesJFo: will do18:19
JFothank you sir :)18:19
apwkomputes, so what does the laptop-detect -v say ?18:21

apwbut what _exactly_ for example mine says18:22
apwWe're a laptop (ACPI batteries found)18:22
komputesapw: sec18:22
komputesapw: "We're a laptop (dmidecode returned Notebook)" 18:22
apwkomputes, i assume that was sudo yes ?18:24
apwwhat does it say without sudo?18:24
apwkomputes, ^^18:27
komputesapw: yes that was with sudo18:27
komputesapw: without it said "We're not on a laptop (no relevant hints found)"18:28
