jjohansendaishadar: most things will still work00:09
jjohansendaishadar: the ubuntu specific patches provide features, drivers, and fixes that are not upstream yet, and in some cases will never be upstream but are useful in their current state for our users00:10

=== sconklin is now known as sconklin-gone
daishadari see... so they may be things i notice but they should be relatively minor, depending on what features i'm using00:13
jjohansenAppArmor provides the default MAC, but if you boot without things will work you just won't have the extra restrictions on some applications00:13
daishadarthe other problem is that i will lose binary drivers (e.g. nvidia), right?  but i should be able to download those from the manufacturer's website...00:14
jjohansenright you loose prepackaged binary drivers, but with some digging you can find the source stubs and blobs and compile them00:15
jjohansenwhere you get them just depends00:15
jjohansenusually from the manufactures website or out of ubuntu DKMS packages00:15
daishadarok, great, so it sounds like it's reasonable.  i'm thinking about buying a thinkpad t410s laptop but apparently there are major issues if you aren't running 2.6.3400:18

cooloneyericm: how can i build the upstream kernel for omap without defconfig file?05:13
jk-cooloney: the defconfigs should still be there, no?05:31
cooloneyjk-: no omap4_panda_defconfig05:35
jk-menuconfig? :)05:35
cooloneyand i tried to build the omap kernel from Tony's linux-omap tree05:35
cooloneyit failed05:35
cooloneyjk-: yeah, i chose TI OMAP system, it will select omap2/3/4 and build for Panda board as well05:36
cooloneyjk-: my bad. i just turned on ARCH_OMAP. forget to turn off OMAP2 and OMAP305:46
cooloneynow it is building 05:46
jk-ericm, cooloney: pull request sent, for the debug macro changes05:58
rippsIt looks like l-b-m and linux-meta were merged together, and now linux-meta is held up in NEW. How long before it gets into the repos?06:08
ericmcooloney, I don't think omap4_panda_defconfig is gonna squeeze into mainline recently07:02
cooloneyericm: i know, it was enabled in omap_4430sdp_defconfig07:23
cooloneyericm: i can build the kernel, but doesn't boot on my board. serial port driver is not set to the right one07:24
ericmcooloney, that always happen, maybe you should change the command line in u-boot07:32
cooloneyericm: still checking the right config, will let you know the result.07:43
cooloneyericm: btw, i am trying tony's linux-omap tree instead of linus mainline07:43
trapmaxanyone experiencing "INFO: task x blocked for more than 120 seconds." messages. In our system it gets triggered when using lvcreate. Started after updating to 2.6.32-24-server -kernel. Workaround?08:58
RAOFtrapmax: That'll happen when something bogs down so much that forward progress doesn't get made fast enough.  I've managed to get almost all my tasks to spit that message when doing a bunch of I/O in btrfs.08:59
trapmaxRAOF: this did not happen before updating to newest kernel09:00
RAOFI'd guess that what's happening is lvcreate is blocking I/O, and is chomping on long enough to trigger that messsage for your other tasks to trigger the message.09:00
smbUsually there would be a backtrace about it. To offer more info09:00
smbMost of the -24 update was ext4 which would not have an impact on lvcreate though09:01
smbOh, actually it is ext4 related...09:01
trapmaxwe have ext4 environment though09:01
smbI was just wondering because lvcreate itself does no filesystem09:02
smbIt could be related to the general writeback regression that we are currently seeing with 2.6.32 kernels. Maybe the ext4 update in some cases just makes it happen more often09:03
trapmaxthis makes our lvm-snapshot -backup virtually impossible09:04
smbtrapmax, I got some test kernels to try if you want to.09:04
trapmaxproduction server. not really confident with that option09:05
smbtrapmax, Hm, hard to offer a workaround that way. The ext4 updates are verified to fix some data integrity issues and seem to cause long(er) IO times in your case09:09
smbthe bug in question would be bug 58509209:09
ubot2Launchpad bug 585092 in linux (Ubuntu) "giant IO delays (affects: 1) (heat: 20)" [Medium,Triaged] https://launchpad.net/bugs/58509209:09
smbAs this relates to some syncs done synchronously, I wonder whether issuing manual sync's from the command line change anything09:10
trapmaxwe have manual sync runnin with 5s sleep09:11
smbHm, ok09:12
smbtrapmax, All the backtraces in your log somehow go through writeback. I am currently trying to get some feedback on the backport of the writeback patches which are in the test kernels. But this will take a bit.09:15
smbUntil then the only thing to play with seems to be the interval of the manual sync. The previous kernels somehow worked but from the tests that were done for the ext4 patches I would not really recommend going back to those old kernel.09:16

jjohansenurghh, don't update!!!10:00
smbjjohansen, Maverick kernel? Or something else?10:01
jjohansenmany things10:01
jjohansenseems kernel is broken for networking10:01
* smb thinks jjohansen should be sleeping instead of updating anyway ;-=10:01
jjohansentheme is broken10:01
jjohansengnome panel seems to be broken10:02
smbSeems everything is ready to alpha310:02
smbHave we been doing something in the networking area?10:02
jjohansenI have a high load almost 50% each cpu, but nothing is showing up via, top, htop etc10:02
jjohansenthe load isn't the kernel as I had to reboot into an older kernel, and it still remains10:03
smbjjohansen, would perf give more hints?10:03
jjohansensmb maybe10:03
RAOFYou might need to re-run apt; they're discussing the gtk update which is probably what has caused your “everything broken”10:04
jjohansentheme is comletely broken too, I had to revert to human :)10:05
* smb likes human. :)10:06
jjohansenRAOF: already have no dice10:06
RAOFThat, plus a reboot, fixed it for me.  Although I didn't have a high load.10:06
jjohansenI'm sure it will get sorted out, soon just putting out the warning that now is not a good time to update10:07
jjohansensmb: do we have a wiki on perf yet10:08
smbI guess an indication that its not kernel or is would be good to know for Leann on the release meeting10:08
smbjjohansen, I am not sure. Maybe not10:09
smbI usually try "perf top" first, that would give an overview on calls10:09
smbjjohansen, Other than that maybe in some presentation slides from chase10:10
smbII think the other was a "sudo perf record" paired with a "perf report"10:11
jjohansensmb: right, but that records a command, I was looking for a way to just get a sampling of all commands and kernel fns10:12
jjohansenafter all what I am seeing is not showing up10:12
smbWould "sudo perf record -a -f -c 5000" be what you are looking for10:13
smbThe 5000 might be a tad long10:14
smbI was stabbing in the dark with the count10:14
smbSeems already quite long with 5010:15
jjohansensomething is really hammering my system load average 3.28 2.10 1.1810:16
smbStrangely you would expect it to show up in top if it gets accounted in the load10:16
jjohansencpus are varying between 30- 100%, but htop isn't showing10:17
jjohansenthat is it shows the cpu load and the processes are like 7%, 9% etc just small little figures10:17
smbI thought that one patch from Chase about accounting small runtimes went upstream as well10:18
jjohansenhrmm, so did I10:20
smbjjohansen, btw, -c# is not really needed. And i have no clue what it relates to10:20
jjohansenI think its something to do with panel icons, as they have been slowly showing up, 1 by 110:20
jjohansenI now have a wifi icon, and a screen orientation icon, which I didn't before10:21
smbI see no such thing here. Oh, you mean your load10:21
smbSo you could try "sudo perf record -f -a", let it run a bit then ctrl-c10:22
smbThen do "sudo perf report"10:22
jjohansenyeah, I'll give that a try, as soon as I get perf installed on this machine, the install is crawling10:23
smbjjohansen, Maybe start it and get some rest? :) I see your continent mostly in the dark...10:25
