apwhydromet, kernel-ppa is just a username in launchpad and on kernel.ubuntu.com ... the user on which our original PPA was attached11:22
apw(before groups existed in launchpad)11:22
hydrometapw: thank you (I have a rule for myself that I'll never use acronyms or words that I don't know the meaning of) :-)11:23

apwogra_, well it sounds like they have some thing to look at their either way11:26
ogra_i'm surprised that went unnoticed11:26
apwogra_, we have resisited CONFIG_NS_xxx on older releass cause they are poor back there and cause issues for others, i think we tried in lucid and failed just recently11:26
apwis it not turned on in oneiric though?11:26
ogra_it is a request of the server team for omap4 atm and they asked me to turn it on on my ac100 kernel (since they use that device in the server team for arm)11:27
ogra_thats what made me notice the message11:28
ogra_LXC is a critical feature for arm server afaik11:28
hydrometI plan to install 11.04 on an Apple Xserve (late 2006 with Xeon Woodcrests) ... but would like to avail of the 3.0 kernel if possible 11:29

DavieyI'm missing context?12:33
DavieyIs this the issue regarding the arm kernel not having certain config options on that we have on server?12:34
ogra_lxc requires CONFIG_USER_NS ... 12:34
DavieySuch as iscis?12:34
DavieyYeah, there are a few we are missing12:34
ogra_with it enabled in .38 i get a deprecation warning on boot12:34
ogra_and apparently that deprecation was made more serious in 3.012:34
Davieyogra_: Why do i care about .38?12:34
apwDaviey, well FF is like now, so if you haven't asked for them soon you won't get them easily12:34
ogra_so that you might be missing bits and pieces for lxc in 3.012:35

apw(input maintainer)15:39
tgardnerpossibly. get cnd to do it. he's got a good working relationship with him15:39

tgardnerogasawara, I sure thought I pushed the work I did last week to add packaging for tools/power/x86/turbostat and tools/power/x86/x86_energy_perf_policy. Do you remember ever having seen it?15:41

=== ppetraki_ is now known as ppetraki
apwtgardner, any idea why we have atkb as =y ?15:55
apwtjaalton, which of poweroff/halt doesn't work ?15:55
tjaaltonapw: well, the one that was mentioned on the list too, where it was determined that 'halt' does the right thing now. the last message I see is "power down", but the system remains on nevertheless15:56
apwright the 'correct' behavior from halt is to stop without powering off15:57
tjaaltonthis is with choosing the shutdown option of the indicator menu15:57
apwwell the correct test is does poweroff work, if not then its broken 15:58
apwie if you do sudo poweroff does it power off, if not then thats a bug15:58
tjaaltonah ok, I'll try that15:58
apwif it works then the menu is likely broken ie using the wrong shutdown, if not then its likely a machine specific bug likely in the kernel or bios i guess15:59
bjf## Kernel team meeting in one hour16:00
tgardnerapw, re: atkb=y, I don't remember16:01
tjaaltonapw: right, poweroff didn't work, so something weird going on16:04
apwtjaalton, so that normally means a bios bug, sometimes it can be worked around with a quirk16:05
smbSomething to try there is to change the shutdown method in /sys from platform to shutdown (looking where exactly...)16:07
smbAh here /sys/power/disk16:07
apwright i think there is also a like reboot=<letter> which can select which method16:08
smbapw, Though that is reboot16:08

hifithere seems to be a problem with my system and 3.0.0, almost all kernels hang for a long time when I try to boot them (before "Starting up..." after grub) except -716:34
hifias there is no output to the dmesg log before that I can't really debug it very much16:35
hifihad some timeout issues with my USB mouse but booting with nousb just removed the usb messages from dmesg16:35
hifiand it seems to hang even with all my USB devices disconnected16:36
hifithe delay takes 1 minute and 50 seconds, where -7 boots around 1 second16:41
apwhifi i suspect comparison of the two dmesgs is the first step, so i'd say get a bug filed the latest kernel and include the -7 dmesg16:43
hifiif I look trough the dmesgs and see nothing that differs16:43
hifiI'll post the bug anyway of course16:44
hifibut there just ain't anything in the dmesg that points to it16:44
hifias the seconds in the log start from 0 and end up around 7 when init gets a hold of the boot16:44
hifioh well, the dmesg is so bulky these days I couldn't tell a clear difference16:45
bjf## Kernel team meeting in 10 minutes16:49
NCommanderapw: so LXC patches were dropped in 3.0? (followup to a conversation you had with ogra this morning)16:51
apwNCommander, the only thing i have said was that some of the things that LCX was requesting were deprecated in 2.6.27 i think it was and finally removed in 3.016:52
apw_if_ ogra_'s testing was with the latest userspace16:52
ogra_i only ran the checkconfig script for stgraber and enabled the needed bits in my ac100 kernel16:53
ogra_what triggered me to ask initially was the warning in dmesg that USER_NS is deprecated16:53
NCommanderogra_: well, Cgroup namespace is known to be depericated and gone as of 3.0 though I can't tell if its actually needed for LXC16:53
ogra_NCommander, USER_NS is, thats the issue16:54
apwand user_ns still exists16:54
ogra_apw, you said it was fully deprecated now16:55
apwogra_, i think we are getting confused16:55
ogra_[    0.270858] ns_cgroup deprecated: consider using the 'clone_children' flag without the ns_cgroup.16:56
ogra_that was the message that got me here 16:56
apwthat thing is fully deprecated yes, _that_ is not USER_NS16:56
ogra_i only get that message since i enabled USER_NS16:56
ogra_and it was a single build i only did for that one option16:56
apwthat may be because you are exiting earlier though16:56
apwthat doesn't make it related to that option necessarily16:57
apwjust means you get past the user_ns check and drop into that warning16:57
ogra_hmm, k16:57
apw(they may be related, but i am not sure you have any evidence of that)16:57
ogra_i dont have any evidence of anything but that warning message16:57
jjohansenogasawara: just a heads up re: feature freeze jdstrand has already set up for an exception for apparmor dbus mediation and there may be another kernel patch on top of what I have for that.  Nothing definite yet, I won't be sure until I get into some more of the dbus patch with him next week17:05

apwbjf, link fixed in the build tools so should be right next week17:07

keesit's _possible_ for it to fail, but the chances are extremely remote.18:54
keesso, I wanted to see if running it again would pass or fail. if it passes, then it's just bad luck, and I can add more cycles to the test18:55
smbOk, yeah. 18:55
loologasawara: Ok, retested 10 kernels out of the 15 and the first 9 were correct, the 10th one was the first wrong result, probably my day-to-day system introduces way too many other random issues to be useful, but with a stable USB key natty setup, it's not likely to interfere again!19:28

hggdhah, thank you, was just going to ask you about the probability20:01
hggdhso we could change it so that it reports only if there is a spike20:02

keeser, allowing 120:03
keesbut it could fail more.20:03
hggdh1 in 50 is already twice the average you expected20:03

hggdhheh. Please be more vocal on these standing requests, I am partially deaf, and never heard it before ;-)20:07
