fabbionehey BenC 09:00
fabbioneBenC: i have a bunch of updates to push to git09:00
fabbioneif you can kindly wait to pull from me, it will spare you another pull in a few hours09:01
=== doko [n=doko@217.205.109.249] has joined #ubuntu-kernel
BenCok, I probably wont pull till I get back up in the morning :)09:05
fabbioneperfect09:05
BenChey fabbione, has your powerbook ever booted where capslock and numlock were reverted?09:13
fabbionehmm i never noticed that09:14
fabbionei don't use any of them09:14
BenClast time I rebooted (even in macosx) they were on to start09:14
BenCit was weird09:14
fabbioneoh..09:14
fabbioneno, never seen09:14
fabbionei need to check with the latest kernel tho09:14
fabbioneit's a bit i don't update the toy09:14
BenCwell, the lights were on, but they weren't enabled09:14
fabbionenope.. never seen09:14
BenCshouldn't be kernel related, since macosx was affected too09:15
BenCI fear hardware issues :)09:15
fabbionepossibly09:15
fabbionewe can verify the OF versions..09:15
fabbionei just don't know how09:15
BenCsomething in /proc/device-tree09:15
fabbioneok i will look at it later09:16
fabbionewife is using it atm09:16
BenCI'm hoping terra/ibm will do that deal again soon, my wife wants one for herself :)09:17
BenCbut that means I'll get the G5 for building/testing09:17
fabbioneehehe09:18
fabbioneBenC: ok i am done with the redhat cluster suite09:30
fabbioneyou can pull anytime09:30
BenCok, thanks09:30
sn9any more test builds of snd-powermac.ko?09:31
BenCnot yet, but I will be getting to it this coming week09:31

MithrandirBenC: prod?03:09
BenCMithrandir: ?03:10
MithrandirBenC: have you done anything which could have made /dev/null turn up as c 0 259 in the latest kernels?03:10
Mithrandir(the static /dev/null)03:10
Mithrandir(when it's on squashfs)03:11
BenCheh, no, pretty sure I haven't :)03:11
sn9sounds like a stray udev rule to me03:11
BenCunless something in squashfs did it03:11
Mithrandirsn9: static dev.03:11
=== zul [n=chuck@ubuntu/member/zul] has joined #ubuntu-kernel
zulheylo03:11
MithrandirBenC: same image looks fine with an older kernel.03:12
MithrandirI see it on both i386 and amd6403:12
sn9i can check ppc03:12
sn9a quick ls -l showed 1,303:13
MithrandirBenC: if you pull down http://cdimage.ubuntu.com/livecd-base/current/i386.squashfs and look at it, you'll see that /dev/null is c 0 25903:13
Mithrandirsn9: how did you check?03:14
BenCwhat do you mean "static dev"?03:14
Mithrandirif you mount that image somewhere and look in /dev03:14
sn9i did ls -l03:14
BenCMithrandir: but what created that file?03:14
Mithrandir: tfheen@thosu /tmp > sudo mount -o loop amd64.squashfs /mnt -t squashfs03:15
Mithrandir: tfheen@thosu /tmp > ls -l /mnt/dev/null03:15
Mithrandircrw-rw-rw- 1 root root 0, 259 2006-02-03 05:53 /mnt/dev/null03:15
MithrandirBenC: mksquashfs.03:15
Mithrandirthis worked with -14 but not -1503:16
sn9oh. i looked at -1403:16
BenCMithrandir: no, what created /dev/null in the dir where you used mksquashfs03:17
MithrandirBenC: debootstrap/makedev.03:17
BenCfrom what I can tell, mksquashfs is like mkisofs, it doesn't create files03:17
sn9you had said "latest kernels" so i thought -14 would be included03:17
MithrandirBenC: it's done on the buildds, which run .1203:17
Mithrandir  * Updated squashfs to latest CVS.03:18
MithrandirI wonder if that can be blamed03:18
BenCMithrandir: so maybe debootstrap is at fault?03:18
BenCMithrandir: is /dev/null ok in the root where deboostrap creates?03:18
BenCso if you mount the squashfs under -14, it /dev/null correct?03:19
BenCif the kernel module is at fault, then the image should be fine, and would work with -14, but not -1503:19
sn9maybe the version of mksquashfs used isn't in sync with the squashfs in the kernel03:19
MithrandirBenC: correct.03:19
Mithrandirsn9: shouldn't matter.03:19
BenCMithrandir: so you verified that this image works correctly with -14?03:19
MithrandirBenC: yes.03:19
MithrandirBenC: or at least, /dev/null isn't on crack03:19
BenCMithrandir: actually it could matter if they made some whacked change in the filesystem03:19
Mithrandirwell, they do actually version the file systems, so if so it'd still be a bug in the kernel module03:20
sn9just because it shouldn't doesn't mean it doesn't03:20
Mithrandirit supports 1.0, 2.0 and 2.1, IIRC.03:20
BenCok, I'm booted into -14 on my powerbook, but I have -15 installed03:20
BenCI'll check into this03:20
Mithrandircoolie, thanks.03:20
BenCMithrandir: no, there was compatibility options in the kernel module that I wasn't sure about03:21
BenCit's possible that I didn't enable/disable one like I should03:21
BenCis this holding up cd's?03:21
=== Mithrandir does a git pull to look at shiny stuff
Mithrandiryes.03:21
BenCI'll make it a priority for today then03:21
Mithrandirthanks03:21
BenCnp03:21
fabbionehey Ben03:22
BenChow long will you be around?03:22
BenChey fabbione03:22
zuloh hey BenC..03:22
BenChey zul03:22
MithrandirBenC: I?  An hour more or so.03:22
BenCI've been spending the past few days out in my barn working on oopses and breezy->dapper regeressions...will be nice to work inside again :)03:22
fabbionehi zul03:23
BenCMithrandir: probably wont be fixed before you leave, but by tomorrow for you :)03:23
fabbioneBenC: you are good to pull from me03:24
MithrandirBenC: thanks03:24
fabbioneBenC: tho it might add a symbol, but don't break the ABI03:24
BenCfabbione: ok, because I'll want to do a quick upload for this squashfs problem with the ABI bump03:29
BenCI might just skip the pull to be safe, and do it after the upload03:29
fabbioneBenC: if you plan to bump the ABI, it would be good to check OCFS2 and import bug fixes03:30
fabbionei didn't get that far03:30
fabbionethe pull is safe..03:30
fabbionebut up to you03:30
fabbionejust don't wait long, there is also that security fix in it03:30
BenCok03:31

BenCuploading soon04:49
BenCI would strongly suggest that you update squashfs tools from CVS04:50
Mithrandiroh, why?  We're in UVF.04:57
BenCit's not a requirement, just a strong suggestion :)04:59
BenCthe new code isn't being used if you use the v2 tools04:59
BenCnot sure what benefits the new code holds, but it may fix some problems04:59
BenCmaybe you can test with both and see if it helps/hurts? especially on ppc where we have oopses05:00

=== _ace [n=ace@63.245.44.11] has joined #ubuntu-kernel
_ace!help09:32
_acehi09:33
_acehave some questions about make-kpkg09:33
_acespecifically how to change the name of the kernel09:33
_aceand later also questions about build-kernelpackage09:34
BenCwhat do you mean "name"?09:34
_aceI made a kernel with make-kpkg and the deb is named kernel-image-2.6.11_2.6.11-0.2_i386.deb09:35
_ace(I know, it's old, I have reasons though)09:35
BenCso what name would you like it to be?09:35
sn9probably linux-image09:36
_aceSomething like kernel-image-2.6.11-w4l-686-smp-megaraid.deb09:36
_acesn909:36
_acelinux or kernel, there's a whole stoy behind that! want me to tell ya ?09:36
BenC--append_to_version=-w4l-686-smp-megaraid09:36
BenCfor s/kernel/linux/ do --stem=linux09:37
_aceah09:37
_acethat's 'stem' about thank you.09:37
BenCnot sure where stem came from, but we set it to linux09:38
_acewill the append-version get rid of the '_2.6.11-0.2_i386' part 09:38
BenCI think the head is that it can be --stem=bsd at some point09:38
BenCthe 2.6.11-0.2 part is the version09:38
BenCor revision to be more exact09:38
BenCall of this is covered in make-kpkg(1)09:39
BenCand you wont be able to get rid of the _i386 part, that's a dpkg-deb thing, you don't want to mess with it09:39
BenCin your first example, linux-image-2.6.11 is the package name, 2.6.11-0.2 is the version+revision, and i386 is the architecture09:40
_aceokay Ill play with that a bit more09:41
_acefor reference, just chek http://www.suares.an/?page_id=2809:41
BenCif you change the package name (--append_to_version), it will change the package name and the version+revision09:42
_aceit also explains the reason I went for the 2.6.11 kernel09:42
_aceHowever, in a wiki i read that you can do apt-get source linux-2.6.8.109:42
_acebut that gives an error09:42
_aceyou can only do that for 2.6.1209:43
_acewhy is that not possible for 2.6.11 ? 09:43
_acealso, the only place I found the 2.6.11 kernel with debian patches09:43
_aceis http://security.ubuntu.com/ubuntu/pool/universe/l/linux-source-2.6.11/09:44
_acethere are three files (orig, diff and dsc) and I can finally (after some days of toying around09:44
_ace)09:44
_acemake a kernel from that.09:44
sn9it all depends on your sources.list09:44
BenCbecause we never shipped a 2.6.11 kernel09:44
_aceBenC: aha ! thx for the clarification!09:45
BenCit was a development package, not really supported09:45
_acenow this kernel that I found09:45
_acewhich *version* is that09:45
_ace2.6.11.7 ?09:45
_aceor some even older one ?09:45
BenCno idea to be honest, It was before my time here :)09:45
BenCprobably older09:45
_aceheh09:45
_acethought so09:45
_aceYou know the whole problem would be away09:46
_aceif win4lin had had a patch for 2.6.12 that *does* include smp support09:46
_acebut that is not the case09:46
_acethat cost me a lot of time09:46
_acewin4lin distributes generic kernels09:46
_acewith 2.6.8.1 09:46
BenCthe 2.6.11 patch doesn't apply to 2.6.12?09:46
_aceand it doesn't boot on my machine since it misses the megaraid09:47
_acedrivers..09:47
_aceeh.. 09:47
_acei haven't tried09:47
BenCand if not, have you tried manually fixing the failed hunks of diff?09:47
BenCyou should try09:47
_acebut i figured why they publish a patch for 2.6.12 that has no smp support09:47
BenCjust because they say 2.6.11, doesn't mean it wont work with 2.6.1209:47
_aceif it were that easy...09:47
_aceguess i should try that...09:47
BenCprobably because the 2.6.11 patch applied cleanly to 2.6.12? :)09:47
_acewould be very strange09:48
BenCI'd give it a go, if you get a couple of .rej's you can clean them up by hand usually09:48
_acehttp://www.win4lin.com/component/option,com_remository/Itemid,76/func,select/id,4/09:48
_acethey *do* have a patch, if the 2.6.11 worked, why make a 2.6.12 patch with no smp support ?09:48
_ace2.6.13 doesn't have smp support09:49
_aceen at 2.6.14.3 suddenly it's back09:49
=== _ace mind boggles...
BenCjust making suggestions, I've no idea what might or might not happen with it09:50
_acegood idea though, I might try that.09:50
_acestill, in the end I want a *real* ubuntu kernel09:50
_aceso now I learned about dpatch09:50
_aceheh09:50
_aceand build-kernelpackage (or whatever that command is called) failed miserably with the 2.6.1109:51
_acestuff and now I know why :-(09:51
_aceI'll go off and try some stuff now... brb...09:51
_acethanks so far...09:52
