brycehogasawara, almost hate to mention it but I got my hands on a system that dislikes rc6 - lp #95466002:01

ah-thanks a lot apw that's exactly what i was looking for02:04

smbAnother 70M since yesterday... yay...08:09
apwsmb, 70 ... sigh08:16
apwsmb, 77 for me, and another new unity08:17
smbMust have some different packages and/or other things installed. Btw, we should have another kernel. The last one is so long ago... :-P08:18
ppisatimoin08:19
smbppisati, ciao08:19
apwsmb, so last week08:19
ppisati90 new pkgs08:21

smb"thank you for joining the mozilla test pilot team"?!? wtf!08:22
apwsmb, oh i saw that on one of my test boxes yesterday evening too.  thought i'd clicked something by mistake ... perhaps not08:23
smbapw, No I guess because they gave us a beta version... bah08:24
apwwhy so i want a beta version in an LTS08:24
smbbecause you can?08:24
apwoh sorry silly me, rules don't apply to everyone, lets upload 3.3-rc7 today08:25
smbapw, There are rules? rules are so last week... :-P08:26
apwso last cycle08:27
apwsmb, interesting, just started firefox here (not my normal browser) and not such popup08:27
smbapw, The test pilot thing was a tab, but weird anyway08:28
smb!#$&, do I only have to reboot to apply the changes or did they steal alt-tab08:36
ubot2`smb: Error: I am only a bot, please don't think I'm intelligent :)08:36
* smb reboots to see whether that brings back alt-tab08:41
apwwell i guess it boots08:43
smbIt seems to...08:45
smbalt-tab is lost though08:45
jjohansenapw: how would you like updated apparmor kernel patches? tree with reverts, and patches that match versions that I am push upstream, or just the diffs.  There will be a rebase against what gets upstream coming at some point too10:11
apwjjohansen, for P i think reverts and new patches is simplest then we can rebase the old ones out of existance10:12
apwanything shiney in this one ?10:12
jjohansenapw: that is what I figured, nothing shiny just bug fixes and changes based on upstream review10:12
jjohansenthe shiny stuff will all be in M10:16
apwjj M ?10:24
apwjjohansen, ^^10:25

ogra_apw, poke13:56
ogra_apw, i ran into bug 954243 yesterday, do you think it would be possible to make devtmpfs mount /dev/pts ?13:57
ubot2`Launchpad bug 954243 in linux-ti-omap4 "booting pandaboard without initrd dies with "init: no available ptys"" [Undecided,New] https://launchpad.net/bugs/95424313:57
ogra_(or tgardner ^^^)13:57
apwogra_, right ... it assumes you setup your environment before upstarts runs, it _assumes_ you have an initrd14:02
ogra_exactly14:03
ogra_that makes initrdless boot impossible14:03
apwall this to save .1s14:03
ogra_heh14:03
ogra_did you measure ?14:03
apwwhen boot currently is in the 50-70 range cause of a bunch of problems14:03
apwno, but frankly it cannot be more than 5s14:04
ogra_on arm its more like 15s14:04
apwout of what 4m ?14:04
ogra_given the bootloader needs >10s to read and shuffle the initrd in ram14:04
ogra_my ac100 currently boots in 25s14:04
ogra_omap4 is rather like 90-120s though14:05
ogra_thanks to the slow bootloader and bad IO on SD cards14:06
apwogra_, ok ... acdording o jodh then if you add --no-log to the command line upstart should stop using pts and in theory you should be able to boot, can you test that for me?14:11
ogra_apw, sure14:12
ogra_will take a moment as my current install is totally trashed14:13

tgardnerogasawara, rebooting gomeisa for kernel update14:57
ogasawaratgardner: ack14:57
tgardnerlets hope it comes back this time. I ran update-initramfs by hand14:57
ogasawarahrm, am I really the only one in the mumble channel15:08
apwogasawara, nope you arn't in mine15:08
apwcking, whats the story with your thinkpad fan investigation15:09
tgardnerogasawara, are really there even now ?15:10
ckingapw, ongoing 15:10
apwcking, james hunt is also seeing issues, he might be able to test15:10
tgardnerogasawara, we can hear you15:10
ogasawaratgardner, apw: we still looking to drop non-smp powerpc flavor?  If so, I best craft an email asap and try to get it dropped in the next upload.15:20
tgardnerogasawara, yeah, please do15:20
tgardnerbjf, did cobbler_web get hosed on your servers after a recent update ?15:30
bjftgardner: no, i can update today and see if that changes15:30
bjftgardner: fully updated, still cobblering15:39
tgardnerbjf, hmm.15:39
GrueMasterppisati: Did something change with the 3.2 omap kernel after Beta1 that would screw with the serial console?  I am not getting much output after kernel boot, and it doesn't appear to start oem-config.15:42
tgardnerbjf, do you remember where cobbler/orchestra keeps its local mirror setting ?15:45
smbtgardner, The ocherstra_proxy snippet?15:45
tgardnertaht might be it15:45
tgardnersmb, ok, where the hell is the proxy snippet? orchestra and cobbler have their bits splattered evrywhere.15:48
smbtgardner, I normally go there via web but I guess you said its broken right now15:49
smbgive me a sec15:49
tgardneryeah, for some reason15:49
smbtgardner, Sorry took a bit. /var/lib/cobbler/snippets15:54
GrueMasterppisati: The problem seems to appear with 3.2.0-18.28.  The ubuntu-server 20120304/precise-preinstalled-server-armhf+omap.img.gz works, 20120305/precise-preinstalled-server-armhf+omap.img.gz fails.  Only difference is the kernel according to the manifests.15:58

ppisatiGrueMaster: ok, let me check16:16
ppisatiGrueMaster: so, what was the first kernel with this regression?16:16
GrueMasterNote that this appears to be serial console specific and omap specific.  omap4 images work fine, as does the omap desktop images.16:17

jodhhi - I mentioned to apw earlier that bug 751689 is still impacting me on precise with 3.2.0-18-generic-pae kernel.16:23
ubot2`Launchpad bug 751689 in linux "ThinkPads overheat due to slow fans when on 'auto'" [Critical,In progress] https://launchpad.net/bugs/75168916:23
apwcking, ^^16:23
jodhIf I fire up say 4 kvm instances or try to build eglibc, the machine just performs a controlled shutdown. It's been freaking me out a little actually as I didn't realize it was this kernel issue re-occuring.16:23
ckingapw, /me on the phone16:24
jsalisburycking, I was able to overheat and crash my system.  I'll send you the data.16:24
jodhThis is on a Lenovo T410 thinkpad with Nvidia graphics. FTR, I have not touched the BIOS since I bought it (around October 2010).16:25
jodhdmidecode says BIOS version is "Version: 6IET72WW (1.32 )" dated 08/27/2010.16:25
ckingjodh, let me send you an email with a description of a tool to try out to capture the failure mode16:35
jodhcking: that'd be great, thanks.16:43
ckingjodh, once we've got some data I can see what's going on and feed this back to Lenovo16:49
jodhOK. It looks like the kernel emits an acpi netlink event when the less critical "hot" state is reached - should some other part of the system be handling that and popping up a window explaining to the user, or maybe trying to forcibly ramp fans, etc?16:50
jodhHaving the system just die on you is kinda alarming ;-D16:50
apwjodh, wuss16:54
jodhmaybe the kernel needs a OOT killer - shutdown the processes that are chewing too much power to try and avoid the forced system shutdown?16:58
tseliotapw, cking: any ideas as to why trying to build a drm module out of the tree would result in "make" ignoring the driver's makefile? I'm getting this "make -f scripts/Makefile.build obj=/var/lib/dkms/drm-dkms/3.2/build/staging/cdv" and then "(cat /dev/null; ) > /var/lib/dkms/drm-dkms/3.2/build/staging/cdv/modules.order"16:59
tseliotapw, cking: full output http://paste.ubuntu.com/883504/17:00
apwtseliot, what is missing ?17:00
tseliotapw: cdv should build as the gma500 module does (they're both in staging and enabled in the config file)17:01
apwcan we see the Makefile17:02
tseliotapw: my staging/Makefile: http://pastebin.ubuntu.com/883554/17:03
apwand in the cdv directory ?17:04
tseliotapw: the main Makefile: http://pastebin.ubuntu.com/883557/17:04
tseliotapw: staging/cdv/Makefile: http://paste.ubuntu.com/883561/17:05
tseliotapw: ignore the default target, I get the same error without it17:05
apwobj-$(CONFIG_DRM_INTEL_CDV) += cedarview_gfx.o17:06
apwtry making that line obj-y +=17:06
tseliotok17:06
apwyou may not have that config set in the third level17:06
apwas they normally come in via the config, and you are cheating i think17:07
tseliotapw: same result. And it's a bit weird to see that I can enable gma500 in my Makefile but it won't work with cdv17:09
ckingjodh, I suspect we should handle that event and crank the fan up to full tilt17:09
apwtseliot, can i have the fma500 Makefile too pls17:09
apwcking, there is a framework for acpi events to shell commands which could do it, but its not very reliable compared to doing it in the kernel17:10
tseliotapw: staging/gma500/Makefile: http://paste.ubuntu.com/883572/17:10
tseliotapw: and I'm building with "sudo make KERNELRELEASE=3.2.2-030202-generic all KVER=3.2.2-030202-generic V=1"17:12
apwand what does this do on its own:17:14
apwmake -f scripts/Makefile.build obj=/var/lib/dkms/drm-dkms/3.2/build/staging/cdv17:14
apwand indeed this:17:15
apwmake -f scripts/Makefile.build obj=/var/lib/dkms/drm-dkms/3.2/build/staging/gma50017:15
apwtseliot, ^^17:15
tseliotapw: make: scripts/Makefile.build: No such file or directory17:15
apwoh you'd need to run those in /lib/modules/`uname -r`/source17:15
apwor is it /build17:15
tseliotapw: right, /lib/modules/3.2.2-030202-generic/build/scripts/17:16
apwtseliot, ok my next debug attempt would be to mv cvd cvd-keep; cp -rp gma500 cdv17:20
apwand see if it builds 17:20
* henrix will be out for ~20min17:20
tseliotapw: sudo make -f scripts/Makefile.build obj=/var/lib/dkms/drm-dkms/3.2/build/staging/gma500 doesn't seem to do anything (I created a link to the path to scripts)17:20
tseliotok17:21
apwtseliot, perhaps :%s/psb_gfx/psb_gfx217:21
apwso you get two different modules17:21
tseliotapw: ah, ok17:21
apwtseliot, that should tell us if its the subdir that the issue, or the staging levle17:22
tseliotright17:24
tseliotapw: yes, the module was built in ./staging/cdv/psb_gfx2.ko17:26
tseliotso I guess it's just the subdir17:26
apwok so its something to do with the makefile in cvd then17:26
apwso i'd start deleting bits of it now17:26
apwyou got rid of default: already yes17:27
tseliotapw: yes17:27
apwtseliot, check the filenames are sensible ... i am a little worrried that the ENVDIR etc might need $(src)/ on the front17:28
apwi am unsure what would happen if none of the filenames point anywhere in ceadaview_gfx-y ... that might do nothing17:29
