kristian-aalborgafter building a (hopefully) working config, can I just "make menuconfig" and then Roosevelt stuff again?00:05
jjohansengenerally yes00:08
kristian-aalborgI guess that building kernels is a fairly good way to get the building process straight00:11
jjohansenhehe, yeah its a great way :)00:13
kristian-aalborgI might put a tutorial together... not on an expert level, obviously... but just how to get things running a bit better00:16

DrDetroitjjohansen: here is the result of my test01:02
DrDetroit2.6.32-28-generic #55-Ubuntu SMP Mon Jan 10 21:21:01 UTC 2011 i686 GNU/Linux01:02
DrDetroit1:40,  2 users,  load average: 0.42, 1.03, 1.2701:02
DrDetroitbut its getting pretty poor performance01:03
DrDetroitI thought 28 was good01:03
DrDetroitI sure don't know what to think or do anymore01:03
DrDetroiti guess i will go back to 27 i think i still have that on my menu01:06
DrDetroitDo you know how long folks have been reporting this issue?01:07
jjohansenDrDetroit: I had a user on the weekend reporting a similar issue but we didn't track it down01:20
jjohansenDrDetroit: I am not even sure it is the same problem, but the symptoms are similar01:21
DrDetroitjjohansen:  I am sort of unsure on how to proceed01:25
jjohansenDrDetroit: lets give -27 a good run and see if you see problems there01:26
DrDetroitjjohansen:  Ok I will do that01:26
jjohansenDrDetroit: from last night bisects I would say we weren't giving the problem enough time to surface01:27
DrDetroitI have been running that rotating torus screensaver01:27
DrDetroitI can tell when things slow down after awhile01:27
jjohansenDrDetroit: there is also the possibility the problem stems from something else that was updated at the same time as the kernel01:27
DrDetroitit ls almost like an old fashioned windows memory leak01:27
DrDetroitI have been running xchat, a terminal window, 3 instances olf mudlet (a mud client) and firefox01:28
jjohansenyes, except in the one I was chasing on the weekend there was plenty of free memory01:28
jjohansenwe should check that when you see the slow down01:28
jjohansenDrDetroit: also we should try killing running processes one by one and see if that clears up the problem01:29
DrDetroitMem:    444440k total,   331720k used,   112720k free,    17080k buffers01:30

DrDetroitthat is current with only xchat and a terminal window running01:30
jjohansenDrDetroit: so yeah good atm, and if we see the slow down check again01:30
DrDetroitjjohansen: its slow now01:31
jjohansenbefore we were just doing a bisect hunt for a kernel regression, this time we will be much more thorough01:32
DrDetroitjjohansen: with those stats01:32
jjohansenwhat does top report01:32

jjohansenokay and the load figures01:33
DrDetroitnothing really shows up hogging cpu or memory01:33
DrDetroitCpu(s):  7.2%us,  3.6%sy,  0.0%ni, 89.3%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st01:34
DrDetroitthats from top 01:34
DrDetroitits crappy poor at 90 percent idle01:34
DrDetroitjjohansen: let me proppse this01:34
DrDetroitI will reboot and go back to 27 but before i do that, i will double check my hardware to make sure it is all working properly including memory01:35
DrDetroiti think it is01:35
DrDetroitbut i can double check01:35
DrDetroitthen i will boot back to 27 and run that for a while01:35
DrDetroitI can report back later this evening or tomorrow early01:36
jjohansenwell yes that is worth doing, which kernel are you running /me thought you were on .2701:36
DrDetroitwhichever you prefer01:36
DrDetroitcurrently this is 28 which i thought was good01:36
jjohansenokay, well lets run a few commands first01:36
jjohansensar 1 10001:37
DrDetroitjjohansen:apparetnly its not installed01:39
DrDetroiti will install it hold on01:39
jjohansensudo apt-get install sysstat01:39
DrDetroitits running01:41
DrDetroitit looks like it is repeating the same stuff, is that what you wanted01:41
jjohansenyes, look at the iowait column01:42
jjohansenwhat kind of figures are you seeing01:42
DrDetroitAverage:        all     37.54      7.69     11.41      0.28      0.00     43.0801:43
DrDetroitthe are all 0.0001:43
DrDetroiti tanke that back i see one 7 a couple 6's and a couple 1's but the majority are 0.0001:44
jjohansenalright so we aren't seeing io backup causing the slow down01:44
jjohansennot a big deal, a few low numbers isn't going to be a problem01:44
DrDetroitthe average is .2801:44
DrDetroiti did run itop but i really didnt understand what it was telling me01:45
jjohansenif we where getting high numbers with high idle, it would indicate that processes are spending all their time blocked on io01:45
kristian-aalborgwill subsequent builds be significantly faster?01:45
jjohansenkristian-aalborg: they can be, it depends on what make determines needs to be rebuilt, based off Makefile dependencies and time stamps01:46
jjohansenso if you change a header file that gets included everywhere, everything needs to be rebuilt01:46
* kristian-aalborg screams!01:46
jjohansenchange a small section of a .c file and likely only 1 file gets rebuilt01:47
kristian-aalborgit *still* does not work :(01:47
jjohansenkristian-aalborg: are you doing make clean?01:47
kristian-aalborgstill goes straight to reboot01:47
kristian-aalborgno, fdr clean01:48
jjohansenah fdr clean will clean out the old build01:48
kristian-aalborgno no... I start out with fdr clean, then cp over the config file01:48
jjohansenif you want to do an incremental build with the build system do rm debian/stamps/stamps-build-XXXX01:49
jjohansenkristian-aalborg: right, 1 clean is needed, after which clean can be skipped if you want to do incremental builds01:49
kristian-aalborgI thought I was going to want that, but not before my kernel works :/01:50
jjohansenhowever depending on your config changes you may need to do a clean01:50
kristian-aalborgjjohansen: obviously, something is still very wrong with the .debs I produce01:51
jjohansenI am not sure how well the dependencies between the config file and the rest of the build system are tracked01:51
jjohansenkristian-aalborg: :(01:51
jjohansenDrDetroit: can you try running vmstat01:51

jjohansenDrDetroit: what processes are running01:53
jjohansenkristian-aalborg: what problems are you seeing with your .debs?01:53
DrDetroitthree terminal windows, xchat01:53
DrDetroitand i just closed 1 terminal window01:53
kristian-aalborgthe debs look fine, I md5summed them too before install01:54
DrDetroitof course there is the stuff on my panel01:54
kristian-aalborgwell, one of them... 01:54
DrDetroittime date, sound etc01:54
jjohansenDrDetroit: try this log out of your X session and log back in, let see if reset a session, restarting the panels etc, has an effect01:55
kristian-aalborgjjohansen: it's what happens when I try to boot the kernel that I installed from those debs that things get weird :/01:55
jjohansenkristian-aalborg: still rebooting?01:55
kristian-aalborgjjohansen: yes01:56
jjohansenkristian-aalborg: and you are just changing the config, no other patches right?01:57
kristian-aalborgI did sudo dpkg -i linux-* this time, would be the same I reckon01:57
kristian-aalborgyes, I use the config that's in /boot on the old box01:57
jjohansenkristian-aalborg: can you send me the config, I will compare and try building a lucid kernel for you01:58
kristian-aalborghttp://pastebin.com/LUM4xbu9 this is what I get when I diff the two files01:59
jjohansenkristian-aalborg: diff your config and the lucid config?02:00
DrDetroitjjohansen: it is significently worse02:00
DrDetroitand my desktop has changed themes02:00
kristian-aalborgsorry for being unclear02:01
jjohansenDrDetroit: interesting, want to look at top and sar output again02:01

DrDetroitjjohansen: we can continue this tomorrow if you would like to work with others tonite02:06
jjohansenDrDetroit: its fine, we can keep going if you want02:06
kristian-aalborgI should get some sleep... 3AM here... 02:07
kristian-aalborgjjohansen: we could continue later, unless you're already building?02:07
jjohansenkristian-aalborg: yeah I kicked it off, but we can continue later it will take a bit to build02:08
kristian-aalborgdepends on what "a bit" is on your system - on mine, it's usually hours ;)02:09
jjohansenkristian-aalborg: say 20-30min02:09
kristian-aalborgI think the smart thing for me is going to bed then02:10
kristian-aalborg30 mins of building02:11
* DrDetroit giggles02:11
kristian-aalborgthen spending either one hour trying to figure out what went wrong or the rest of the night tweaking ;)02:11

fairuzHi morning07:40
fairuzjjohansen: can i start with my questions? :D07:42
fairuzjjohansen: about /usr/src/linux-headers-xxxxxxx, I need one for each kernel i compile?07:43
fairuzjjohansen: because i see files in /lib/modules/xxxxxxxx/build point to the headers folder07:44
jjohansenfairuz: define need, they are good to have but the headers aren't "needed" to run the kernel07:44
fairuzjjohansen: yes, i mean for compiling external module07:45
fairuzjjohansen: for external module, i need all of those right?07:46
jjohansenyes, the headers are needed for compiling external modules07:46
fairuzjjohansen: and i suppose there are make install_headers to create this folder?07:47
jjohansenfairuz: the target is actually headers_install07:48
jjohansenfairuz: or maybe headers_install_all07:49
fairuzjjohansen: I think I already tried that, but no idea where the files go after it finishes07:49
jjohansenfor the work I've done I've never needed to do it, but yeah its there07:49
fairuzjjohansen: I compile the kernel with custom name and it boots ok07:53
fairuzjjohansen: just there is no display right now, which I think it's normal because I'm not installing the modules yet07:54
jjohansenfairuz: sounds about right07:54
fairuzjjohansen: i just get the plain console. I will try now to use sshfs to install the modules. I tried it yesterday but got some problems07:55
fairuzjjohansen: something about permissions07:56
jjohansenfairuz: hrmm, I think I might know what you hit, give me a minute to find it07:56
jjohansenfairuz: http://blog.sumostyle.net/robg/2006/08/07/some-useful-sshfs-options/08:05
fairuzjjohansen: ok i'll take a look at it08:05
jjohansenyou may need allow_root or allow_other, I can't remember which08:05
jjohansenI think I did the mount as my regular user and I had to use allow_root, to get the install to work08:05
fairuzjjohansen: i'll try that08:09
fairuzjjohansen: have to reboot with my working kernel first :D08:09
fairuzjjohansen: it's not a simple thing this whole kernel thing. To get it booted is one thing. To get it works with all the modules is other thing.08:11
jjohansenyeah it can be a pain, there are reasons to like monolithic kernels08:12
fairuzjjohansen: so you do sshfs without sudo ?08:16
jjohansenfairuz: that I can't remember, the remote install I was doing where a while ago08:17
jjohansenI know I did sudo make install ; sudo make modules_install08:17
fairuzjjohansen: ok. 08:18
jjohansenbut I think the fuse mount was probably done as a user08:18
jjohansenI know I did the compile as just a plain user08:18
fairuzjjohansen: it dont let me to use -o, I need to edit /etc/fuse.conf08:18
jjohansenfairuz: yeah, I think I had to do that too08:19
jjohansengetting it setup was a bit of a pain08:19
jjohansenbut it worked well once I had it08:19
fairuzjjohansen: one thing i find it weird, before it asking the remote password. It asks for my password 3 times. Each time.08:20
jjohansenhrmm, I don't remember it doing that, but its possible, /me needs to go back and try doing a remote install like this again some time08:21
fairuzjjohansen: it's installing the modules now :D08:52
fairuzjjohansen:  I use sudo sshfs -o allow_other,default_permissions <host> <mountpoint>08:53
jjohansenyeah that sounds like it should work08:54
=== DrD_away is now known as DrDetroit
DrDetroitand good morning to all08:54

jjohansenmorning DrDetroit08:55
DrDetroitjjohansen: I have run the 27 kernel since falling asleep last night08:55
DrDetroitit seems ok , have not seen any issues yet08:55
jjohansenhrmm okay08:55
DrDetroitlet me open up a few more apps and see what happens08:55
fairuzjjohansen: It finishes :D09:05
fairuzjjohansen: but I think I should change the symlink for build and source09:06
fairuzjjohansen: right now it points to the mounpoint09:06
jjohansenhehe, yeah that might be an idea09:06
fairuzjjohansen: maybe I should change it directly to my source folder in the build machine?09:07
fairuzjjohansen: since it's accessible by network09:07
jjohansenfairuz: that should work09:08
fairuzjjohansen: i will be happy if this works :D09:08
fairuzjjohansen: hmm still no luck. I got FATAL: Could not load /lib/modules/2.6.35-980-omap4-fairuz/modules.dep: No such file or directory09:24

fairuzjjohansen: wait i go restart all machines and retry09:53
DrDetroitwell now, that was strange, my screensaver went off, but returned back to the regular screen09:59
fairuzjjohansen: is this something to do with initrd?10:01
fairuzjjohansen: at boot, i load uImage and also uInitrd10:01
jjohansenfairuz: yep, what files are in /boot/10:02
jjohansenDrDetroit: its not unheard of for the screen saver to have odd bugs10:02
DrDetroithehe, i know, its a computer, it's all smoke and magic to me10:02
jjohansenif you can replicate it is worth filing a bug over10:02
fairuzjjohansen: there are some vmlinuz files, system.map files, initrd.img-xxxxx10:03
jjohansenfairuz: so you need to make an initrd10:03
fairuzjjohansen: there are files for my old kernel, no files for my new kernel10:03
fairuzjjohansen: ah ok.. any help to do that?10:04
jjohansenfairuz: no files at all or no initrd10:04
fairuzjjohansen: what this thing do? it's ubuntu thing or kernel thing?10:04
jjohansenfairuz: hrmmm well sort of both10:04
jjohansenthe kernel doesn't need one but one is often used for flexibility10:04
jjohansenubuntu uses one10:05
fairuzjjohansen: i have for example initrd.img-2.6.35-980-omap4 but no initrd.img-2.6.35-980-omap4-fairuz10:05
jjohansenfairuz: I am going to assume its an initramfs10:05
fairuzand also i have vmlinuz-2.6.35-980-omap4 but no vmlinuz-2.6.35-980-omap4-fairuz10:05
fairuzjjohansen: same thing applies for System.map and abi files10:06
jjohansensudo update-initramfs -ck 2.6.35-980-omap4-fairuz10:06
fairuzjjohansen: ok10:06
jjohansenfairuz: hrmm, do you do a make install?10:07
jjohansenfairuz: or did you just copy the vmlinuz10:07
fairuzjjohansen: nope, just make xxx_defconfig and make uImage10:07
fairuzjjohansen: then i just copy the uImage10:07
jjohansenfairuz: generally make install will copy those as well as the kernel10:07
jjohansenyou could use the same sshfs trick to do make install as make modules install10:08
jjohansenfairuz: also update-initramfs isn't the only way to make a ramdisk but it is the way ubuntu uses, I am not up to date on other methods10:10
fairuzjjohansen: i have now initrd.img for my kernel10:14
fairuzjjohansen: it still not working. i will try the make install now10:16
jjohansenfairuz: make install and then remake the ramdisk10:16
jjohansenfairuz: instead of -ck use -uk10:17
fairuzjjohansen: actually it generate the initrd but it gives this grep: /boot/config-2.6.35-980-omap4-fairuz: No such file or directory10:18
fairuzi should copy my config to /boot folder first?10:18
fairuzor make install will do that10:18
jjohansenhrmm, configs shouldn't be needed but system.map and abi I believe are10:19
jjohansenfairuz: but if its complaining about the config missing if make install doesn't put it there copy it yourself10:20
fairuzjjohansen: ok understood10:22
fairuzjjohansen: sudo install will not recompile the kernel i suppose?10:28
jjohansenfairuz: sudo make install should not recompile the kernel10:29
jjohansenwell at least as long as you haven't changed any timestamps10:29
fairuzjjohansen: if both machines have different time? :D10:31
fairuzjjohansen: because right now i'm seeing a lot of CC10:31
fairuzjjohansen: which i think it's in the process of the compiling10:31
jjohansenfairuz: its the files time stamps that should be important, I'm not sure why you would be seeing lots of CC10:31
jjohansenwhich is indeed compiling10:32
fairuzjjohansen: well i will let it compile then ( which will take forever since it's compiling on the target machine )10:32
fairuzjjohansen: So if I understand well, I should do make install that will install necessary files to /boot10:33
jjohansenfairuz: it should10:34
fairuzjjohansen: and this file is used during the boot i suppose?10:34
jjohansenfairuz: or for setting up the module dependencies, building the initramfs (which is used during boot)10:35

ogasawarappisati: I want to recall that it's because the patch is already in maverick/lucid via stable updates, but I'll have to double check13:46
tgardnerogasawara, if so, shouldn't it be 'fix released' ?13:47
ppisatiogasawara: ah ok13:47
ppisatippisati: i didn't check the tree before asking, ok13:47
ogasawaratgardner: yah, I suppose it could be marked Fix Released rather than Invalid13:48
tgardnerogasawara, that more closely matches the CVE tracker state, doesn't it?13:48
ogasawaratgardner: the CVE tracker state is marked as not-affected so I guess it just depends how we want to interpret it13:50
tgardnerogasawara, well, the security team has been dinging us for not noticing when stable updates fix a CVE, even though its not noted in the upstream commit log.13:51

sconklintgardner: so the ABI problems with the packages were not the root cause of the FTBFS? (just trying to stay current)14:50
tgardnersconklin, I can't say for sure since LUM had the same issues, and is in the dependency chain.14:51
tgardnersconklin, thats gotta get fixed first before I can tell if its the root of the HPPA FTBS. its just about gotta be that 'cause nothing else has changed.14:51
sconklintgardner: yeah, and it makes sense that it could be the cause14:52
tgardner sconklin: so, in order to avoid this ever happening again, I'm ripping out all generated files from dapper/hardy and subsidiary packages.14:53
sconklintgardner: great! Brad and I had the "OMG how many other packages could have this problem" conversation last night, but you got there first14:54
sconklinEven more scary is that potentially it could have happened and not resulted in a build failure14:54
tgardnersconklin, it likely is an indicator of how many folks aren't using Hardy LUM 'cause I don't think the modules would load, bot nobody has complained.14:55
smbtgardner, Was Hardy also still carrying the abi number asclear text or was it just re-creating those depending files?14:55
sconklinBrad and I have also talked about trying to get download stats for dapper and hardy, I'm curious how many consumers they have, and I think the stats are available now14:56
smbtgardner, I usually would notice when booting the test laptop. But it is more something like "hm, it is very silent on boot"14:56
tgardnersmb, Hardy LUM/LBM had debian/control committed in the repo, which makes it easy to _not_ correctly generate the ABI info.14:56
tgardnerHardy LRM as well14:57
fairuzhow to generate vmlinuz kernel file? I just have uImage, zimage and compressed/vmlinux. Thanks14:57
smbtgardner, Ah yes, I was unsure whether Hardy also still have the abi number in the rules file instead of using the number from the changelog14:58
smbThat is what caught me when doing dapper lrm14:59
tgardnersmb, dapper is worse. you _have_ to run the bumpabi target in order to get the udeb stuff henerated correctly.14:59
smbtgardner, Even worse that is the kernel package only. There is no bumpabi target in lrm15:00
tgardnersmb, right, but we only have to live with that for a couple of months more15:00
smbThat is the hope one can hold on. :)15:01

jjohansensconklin: so we have expanded the range and each bisect is being tested for the 3-4 hours necessary for the problem to surface18:44
