[07:37] <Tm_T> Hi, how do I could debug a kernel panic, possibly caused by a scheduler
[07:38] <Tm_T> I have ~daily kernel panics, and I see line of "BUG: Error while scheduling atomic: <binary that was active at that time>" sort
[07:43] <Tm_T> this is 2.6.38-11-generic running on Intel, I suppose this CPU: http://ark.intel.com/products/41498/Intel-Celeron-Processor-900-%281M-Cache-2_20-GHz-800-MHz-FSB%29
[07:53]  * apw yawns, bouncy internet this morning, not good
[07:54] <Tm_T> heh, struggled 2 first hours in the office for constantly disconnecting wlan
[07:54] <Tm_T> s/for/with/
[07:54] <jk-> hey apw
[07:54] <apw> morning
[07:54] <jk-> been keeping the rioters at bay?
[07:55] <apw> jk-, two nights ago they were burning dowm the shops 5 mins from my house, but its sounding quieter now
[07:55] <jk-> jeeeez :/
[07:56] <apw> jk-, first and only time i've packed a bag in case i had to run
[07:56] <apw> and i lived though the constant bombing by the IRA, somehow this is more dangerous, more random
[07:59] <apw> but i heard nothing last night so perhaps we are past the worst
[08:01] <jk-> i hope so...
[08:13] <apw> we have had a pile of police on the streets, thats going to cost a few bob sadly
[08:13] <apw> "peaceful night across the country" is todays message ... phew
[08:16] <apw> "those who think they have got away with looting will be supprised today when the doors start to go in" like the sound of that
[13:11] <hggdh> sconklin: bug 824520 during QA for 2.6.38-11.48, generic-pae. Did not reoccur, so I am not marking as failure. Nevertheless you folks should have a look
[13:11] <ubot2> Launchpad bug 824520 in linux "WARNING: at /build/buildd/linux-2.6.38/arch/x86/kernel/apic/ipi.c :109 default_send_IPI_mask_logical+0xb1/0xf0()" [Undecided,New] https://launchpad.net/bugs/824520
[13:52] <sconklin> hggdh: all testing results like this need to be posted to the tracking bug, so they aren't lost on IRC. I've copied this one to the bug. I'll have a look and see whether we should pass it or not
[13:54] <hggdh> sconklin: I was giving yuou advance warning. When I finish a test sequence, I write in anything interesting, including bugs. No need to tell me this should go into the tracking bug
[13:54] <sconklin> hggdh: ok, thanks, sorry to jump on that
[13:55] <sconklin> maybe I can have an answer before you are done
[13:55] <hggdh> this is my hope. I cannot tie it to the kernel so far
[13:59] <siji> Hi All,
[13:59] <siji> First want to report some bugs in ubuntu-natty kernel (for ARM) 
[14:00] <siji> the default driver module for Touchscreen ads786 is not the right one 
[14:01] <siji> And now am trying to build this module , but not succeeded 
[14:02] <siji> Steps followed : Downloaded the kernel source from rep. by apt-get install linux-source
[14:02] <sconklin> hggdh: Any idea which test was running when this occurred? Maybe it's in the logs and I don't know where to look
[14:03] <siji>  make modules SUBDIRS=drivers/input/touchscreen/
[14:03] <khanx> hey everybody
[14:04] <khanx> im new to this... which languages do i need to know to customize my kernel ?
[14:04] <siji> English & C :)
[14:05] <khanx> so far so good. :P
[14:05] <siji> :)
[14:06] <khanx> im not so familiar with ubuntu though. like i said im new to linux, but im not bad with C and java
[14:07] <siji> Then i suggest you to familiar with linux/ubuntu first then get into Linux Kernel 
[14:08] <khanx> and whats your advice on how to become familiar with ubuntu fast?
[14:08] <khanx> i feel like its gonna take ages
[14:09] <khanx> any e-book or online texts recommended ?
[14:09] <siji> not at all 
[14:09] <siji> Download ubuntu ISO isntall it and play with it
[14:09] <hggdh> sconklin: at this point in time it was the LPT lite
[14:10] <hggdh> it really does not help that a lot of programs get to print warning/error messages without identification :-(
[14:11] <siji> khanx, get familiar with basic unix/linux commands 
[14:12] <siji> this will make your " Playing with Linux" more easier  
[14:14] <siji> any help pls 
[14:15] <siji> Or any one can provide me ads786.ko (touchscreen module)  for 2.6.38.8-omap 
[14:16] <apw> siji, if you have ARM specific questions you may get quicker answers on #ubuntu-arm, the peeps who mostly have the h/w hang out there
[14:16] <siji> apw, :)
[14:16] <ogra_> apw, lol
[14:17] <ogra_> apw, i have no clue how to only build modules in subdirs of the kernel tree
[14:17] <siji> he he
[14:17] <ogra_> never had to 
[14:17] <ohsix> make M= isn't it?
[14:17] <ohsix> or make module.ko
[14:17] <siji> ohsix, means
[14:17] <ohsix> there's "make help" too
[14:17] <ogra_> so i'm surely a bad candidate to support that :)
[14:18] <siji> ok
[14:19] <siji> (ohsix, looking into make help )
[14:19] <apw> building only in a subdir, hmmm, that is in the docs somewhere something like fakeroot debian/rules prepare-<flavour>; make O=debian/build/build-<flavour> <directory name>
[14:19] <apw> or <directory>/<module>.ko at the end
[14:19] <apw> not that i ever do it, i normally just build the lot
[14:19] <siji> apw, ya it worked for me 
[14:20] <siji> but it hasnt built whole kernel modules
[14:20] <siji> I have defined he directory name 
[14:21] <siji> ./touchscreen which is having more than 10 driver modules, but it built only three 
[14:21] <siji> And unfortunately my module was not there in those three ;(
[14:22] <apw> well it will only build the ones which are turned on in your config too
[14:22] <siji> Am not a expert in kernel , so i feel something wrong in the .conf or some where else
[14:22] <siji> apw, understood
[14:22] <siji> I hve tried many times by configuring it 
[14:22] <apw> if you want foo.ko built there will be something like obj-$(CONFIG_FOO): foo.ko in the Makefile, which tells you the CONFIG to look for in your .config
[14:23] <siji> apw, ok 
[14:23] <siji> let me have a look into it
[14:23] <ogra_> apw, well, the initial issue that drove siji to try the recompile was that the module shipped in the package breaqks with undefined symbols on loading
[14:24] <ogra_> apw, which i find extremely weird for a module built in the same package
[14:25] <siji> ogra_, apw , then by building the kernel from the same source(ubuntu repository)  again will make any sense for me ?
[14:25] <apw> ogra_, odd indeed but not impossible i think
[14:25] <apw> if the dependancies in the Kconfig are broken
[14:27] <siji> apw, broken locally in my setup only ?
[14:27] <bjf> the kteam-bugs is 831M
[14:27] <bjf> -EWRONGCHAN
[14:28] <apw> siji, likely generally if they don't work with the ones in the archive
[14:28] <apw> is there a bug or error messge i can look at
[14:28] <siji> apw, ok
[14:29] <siji> the bug is with ads7846 driver module (Touchscreen - used TSC2046 in the Expansion board,and it connect with DM3730 by SPI port) 
[14:30] <siji> ogra_, sorry hasnt got time to report the bug report . apologise ..
[14:31] <ogra_> dont apologize, file it instead :P
[14:32] <siji> :)
[14:34] <tgardner> ogasawara, am working on jjohansen's AA 13 patch set.
[14:35] <ogasawara> ogasawara: ack, I'm lookin at ike's
[14:35] <tgardner> cool
[14:43] <smb> morning
[14:55] <siji> ogra_, done :)
[14:56] <siji> good learning for me :) 
[14:57] <ogra_> siji, tell apw the bug number
[14:57] <siji> o
[14:57] <siji> ok

[14:58] <siji> yes the same 
[15:17] <apw> ogra_, do you have a pointer to that possible arm smb issue
[15:18] <ogra_> apw, omap3 has no SMP :)
[15:18] <smb> ogra_, omap4
[15:19] <ogra_> err, you said smb :P
[15:19] <smb> Though I would probably prefer not being called an issue... :)
[15:19] <ogra_> sorry, running a meeting atm
[15:19] <smb> ogra_, He was trying to say smp
[15:32] <apw> jjohansen, about ?  i've replied to your TOCTOU patches, i think there is an issue with the Maverick one
[15:32] <smb> apw, He is here though I need to ask
[15:32] <jjohansen> apw: oh? that is possible
[15:33] <apw> jjohansen, and i am wondering if you are doing backports for lucid and hardy or not
[15:34] <jjohansen> apw: ah yeah, sorry /me couldn't find those last night and hasn't gotten to it this morning yet
[15:39] <apw> jjohansen, ok will wait on those rather than doing them
[15:40] <jjohansen> apw: okay, I'll take a look at the Maverick one again too
[15:40] <apw> jjohansen, my review comments are on the mailing list
[15:41] <jjohansen> apw: thanks
[15:46] <ogra_> smb, apw, meeting done, so what was the issue 
[15:47] <smb> ogra_, Question was whether you got a pointer to the bug concerning poor performance in smp mode on the panda
[15:47] <ogra_> the bug number you mean ? 
[15:47] <smb> yep

[16:00] <tgardner> pgraner, looks like the ISO builder ran last night? 
[16:04] <tgardner> bummer, still getting apt-get trap divide error
[16:33] <cjwatson> does anyone here who is (a) in ubuntu-core-dev and (b) not in techboard or ubuntu-release have a bug task they'd like to nominate for a stable release?
[16:33] <cjwatson> right now you can just do it; I want to make a change to the stable release ownership in LP and would like to make sure that doing so does not break it this
[16:34] <cjwatson> but I can't test it myself since I'm overprivileged
[16:34] <apw> tgardner, ^^ is the only one i think who fits that criteria
[16:34] <tgardner> cjwatson, hmm, that might be me.
[16:35] <cjwatson> if you have a suitable task to nominate, then yeah, you have the level of privileges I'm looking for
[16:35] <apw> tgardner, you can safely nominate any of our cves to like karmic and the tools will slam them invalid later
[16:36] <tgardner> cjwatson, are you wanting to mess with our ability to make nominations? its already difficult in that very few of us _can_ do it.
[16:36] <apw> s/cves/cve bugs/
[16:36] <cjwatson> tgardner: I want to make sure I'm *not* messing with your ability to do so
[16:36] <tgardner> cjwatson, ah
[16:36] <cjwatson> actually, here
[16:36] <cjwatson> tgardner: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/752694 - can you see an "approve/decline" thing there?  (don't click it yet)
[16:36] <ubot2> Ubuntu bug 752694 in grub2 "Grub2 installs on the wrong device if in a RAID config" [High,Confirmed]
[16:37] <tgardner> cjwatson, yes
[16:37] <apw> tgardner, http://people.canonical.com/~kernel/reports/kernel-cves.html any of those bugs can be safely nominated to anything, and we'll cope
[16:37] <cjwatson> tgardner: OK, reload - can you still see it, and if you hit approve, does it work?
[16:38] <cjwatson> (I've just changed natty's owner from ubuntu-core-dev to ubuntu-release)
[16:38] <tgardner> cjwatson, it appears to have worked
[16:38] <cjwatson> excellent, thanks!
[16:39] <cjwatson> I'll go and change the other stable releases now then.  Please let me know if you notice regressions in your ability to nominate things
[16:39] <tgardner> cjwatson, will do.
[16:40] <tgardner> apw, since FF approaches, perhaps its time to get an empty oneiric LBM package in the archive before it gets difficult.
[16:42] <apw> i think ff offically is in 15 mins, but lbm has always been treated at part of the kernel
[16:43] <apw> but yes i think its time
[16:43] <cjwatson> (BTW, the fix for bug 451390 ought to have improved the nomination situation for you guys)

[16:51] <apw> tgardner, i'll put the LBM on my todo for tommorrow
[16:51] <tgardner> apw, ack
[16:52] <apw> tgardner, you will be pleased to know i have spent several hours un-fooking my email so i have some hope of keeping up on it
[16:52] <tgardner> apw, be sure to check the repo in your morning in case I manage to get to it yet today.
[16:52] <apw> tgardner, ack
[16:53] <tgardner> apw, I'm pretty ruthless about keeping my inbox down to just a couple of emails by EOD
[16:54] <apw> yep and working on a similar scheme but it needs for my filtering to be sane and work, which has been the big battle
[16:54] <apw> i think i have just about won
[16:54]  * tgardner likes procmail
[16:59] <tgardner> ogasawara, does '(drop after 3.0)' make sense for a clean cherry-pick ?
[16:59] <apw> they should drop themselves on rebase anyhow
[17:00] <ogasawara> tgardner: sorta unneeded I guess as apw says they'll drop anyways
[17:00] <tgardner> apw, ogasawara: you mean for the P series kernel, or for the once more that might happen for oneiric ?
[17:01] <apw> (for P i am assuming)
[17:01] <ogasawara> tgardner: they should drop for P, possibly for O if they hit stable and I rebase
[17:01] <tgardner> ok, I'm just being OCD
[17:01] <ogasawara> tgardner: I assume you're referring to ike's patches
[17:02] <tgardner> ogasawara, yep
[17:03] <ogasawara> tgardner: if it makes you feel better, I'm indifferent so if you want to fix up and push over the top, feel free :)
[17:03] <tgardner> ogasawara, I'll get over it. some good drugs will help.
[17:05]  * smb wonders whether there some involved already...
[17:19] <apw> tgardner, you got any rtl8192cu's ? if so do they work ?
[17:19] <tgardner> apw, I can't hear you....
[17:20] <apw> damn

[17:22] <smb> think I got a similar one now
[17:22] <smb> it worked

[18:34] <tgardner> smb, I've been using the cross compiler since the armel schroot doesn't work
[18:35] <smb> tgardner, Ah, ok. Will do the same then

[18:36] <smb> Heh, ok was thinking that would need to be somewhere
