GoinkI am having timing problems on a dual core amd64. Does anybody know how i can fix it?02:02
BenCwhat sort of timing problem?02:02
BenCclock running twice speed?02:03
GoinkClock iss ssspeeding, bbut at  all sorts oof sspeeeds, it warrries aa  lot, and i get ddooouuubble orr mmmoree   kkkeey  pressess02:04
BenCboot with noapictimer02:04
BenCadd it to /boot/grub/menu.lst in the kopt02:04
BenCand rerun update-grub02:04
GoinkThank you! I'll try that!02:05
BenClet me know if it works02:05
GoinkWill do02:05
infinityBenC : Pong.04:30
BenCinfinity: with -8.0, I am doing a lrm 2.6.15.3-106:26
BenCnew acx firmware and filenames for that firmware06:26
BenC-8.10 I mean06:26
BenCjust a heads up06:27
fabbionemorning07:03
BenChey fabbione07:04
fabbionehey Ben07:04
fabbioneBenC: I got a regression somewhere, but i think it's udev related07:04
fabbionemidiC$something devices are now created in /dev instead of /dev/snd07:05
fabbionethat's one07:05
fabbionethe airo module for pci cards is problematic07:05
fabbioneit is loaded properly but it doesn't work at the first shot07:05
fabbionei need to unload and reload to make it going07:05
fabbionereproducible quite often. what do you want me to do to try debugging it?07:06
BenCairo cs works perfectly for me, that's weird07:06
fabbioneairo cs yes07:06
fabbionethis is Pci07:06
BenCnot sure, is it a regression?07:07
fabbioneyes..07:07
fabbioneit also tends to change interface name07:07
BenCwant to start recompiling kernels? :)07:07
fabbionelike at the first time is eth207:07
fabbioneunload -> reload -> eth0 ?07:07
fabbioneyeah sure i have no problems with that07:07
BenCnot sure about that07:07
fabbionerecompilng it's not an issue07:07
fabbioneone of the pci ethernet (marvell) always shows up as eth107:08
fabbioneeven if alone on the system..07:08
BenCok, you'll need git07:08
fabbioneit's kind of weird07:08
BenCand compile out of the tree07:08
fabbioneyeah07:08
fabbionewill try that during the week07:08
BenCgit-log, find hte sha1's for "Linux v2.6.1[432] "07:08
BenCgit-branch 2.6.14 <sha1>07:09
fabbionei know it works on .1207:09
BenCdo that for 2.6.1[432] 07:09
BenCgit-checkout 2.6.1307:09
fabbioneyup07:09
BenCbuild, and if it breaks, good, if not try 2.6.1407:09
fabbioneeheheh07:09
BenConce you find work/nowork07:10
BenCthen start using git-bisect07:10
fabbionewhat does that do?07:10
BenCyou could just start out with 2.6.12 and HEAD07:10
BenCgit-bisect makes your life a lot easier :)07:10
BenCgit-bisect start07:10
BenCgit-bisect good 2.6.1207:11
BenCgit-bisect bad HEAD07:11
BenCit will bisect the commits, and checkout at the middle point07:11
BenCyou build, you test, and you come back and do "git-bisect <good|bad>"07:11
BenCit wil bisect again, and you keep doing that cycle until it tells you "This commit broke it"07:12
fabbioneah cooooolness!07:12
BenCgood/bad depends on whether your test suceeded or failed07:12
fabbioneyeps07:12
fabbionethat was clear07:12
BenCit's so simple I feel I have to overexplain it :)07:13
fabbioneahah07:13
BenCit's what I used to track down the sparc64 oops on my e3k07:13
fabbioneyeah it makes sense07:15
fabbioneassuming that when you bisect you can actually build07:15
BenCyeah, you can bump up/down the commit it stops at if you hit a bad spot07:17
fabbionei see you are brave enough to readd misdn07:18
fabbioneit was removed because upstream sucks07:19
BenCdoko requested it07:19
fabbioneat least it did at that the time07:19
BenCit's compiling cleanly07:19
fabbioneok07:19
fabbionethey must have started again07:19
fabbioneit was OOPSorama in hoary07:19
BenCheh, didn't say I tried using it :)07:19
fabbione .../usb/media/podxtpro/.tmp_versions/podxtpro.mod  |    2 07:19

BenCthanks, removed07:21
fabbioneno problem.. i just woke up and bored to death as you can see ;)07:21
BenCheh, try perusing bugs for 3 days07:22
BenCI think I've gone through half of them07:22
BenCbad thing is, if I stop now, I don't think I'll remember where I left off07:22

fabbione    [UBUNTU:debian]  Add ABI files (missing hppa and sparc still)07:23
fabbione <- they are in the archive now07:23
fabbioneif you want i can push them07:23
BenCI have them07:23
fabbioneup to you07:23
fabbioneok07:23
BenCjust need to commit it07:23
BenCmy abi grabbing script is smooth07:23
BenCI need to put it in the debian/bin/07:24
fabbionethat's a good idea07:25

infinityBenC : Which firmware are you grabbing for acx_pci stuff?... I've been all over the interweb and seen many conflicting reports on what we should be shipping.08:33
infinityBenC : Also, I already rolled a .3 with updated nvidia and ati drivers, so we may as well just do this all at once.08:33
infinityBenC : And I'm going to send out a mail to -devel/-users today to have people test vga16fb at 640x400 with kernels I've tossed on people.ubunut.com.  Would it be worth holding off on -8.10 until I gte reports back from that?08:34

BenCinfinity: sorry, went to bed02:57
BenCinfinity: but yeah, I can hold off. I'll get you a tarball of the firmware I have02:57
BenCinfinity: bad thing is there is a table of firmware, different cards need different versions, but the driver (even the new one) isn't smart enough right now to load different versions for different cards02:58
BenCthe new driver is smarter than the old one though02:58
BenClike the RADIO16.BIN thing is totally broken with the new driver02:58
BenCyou have to have a pristine firmware tree (no firmware of other names that it looks for) in order for things to load right02:59
BenCso you really can't have acx100 and acx111 firmware sitting together03:00
BenCinfinity: I have an idea03:43
BenCinfinity: so wake up! :)03:44
=== infinity is here.
infinityAbout to send mail to -users and -devel about the vga16fb thing, so I'm here for a few minutes.03:59
infinityWhat's your stellar idea?03:59
infinity(Can we not just fix acx_pci to DTRT about firmware, whatever TRT is?)03:59
infinityMap certain filenames to PCI IDs or something?04:00
infinity(or something less crude, if that's possible)04:00
infinityBenC : flashy noisy nick alert.04:00
BenChey04:13
BenCI have a fw tarball04:13
BenCseveral different versions for acx100/usb acx100/pci and acx111/pci04:14
BenCwe'll have a default (newest version)04:14
BenCand the module will take firmware_ver=X.X.X to use a different version if they need to04:14
BenCif they have do that to get it to work, they'll be instructed to send us lspci/lsusb output so we can code it into driver04:15
BenCinfinity: flash back04:15
BenCI'll send you the tarball when I'm done04:16

infinityhttp://cerberus.0c3.net/~adconrad/vga16fb.txt04:23
infinityBenC : Does acx_pci even support USB devices?... Or do we now have an acx_usb or something?04:23
infinityBenC : Also,want to read over that mail before I hit "send"?04:23
BenCwe have acx_usb04:23
BenCbut, the new driver is usb/pci combined04:24
BenCyeah04:24
BenCit's just acx.ko04:24
infinityAnyhow, however you work the firmware is up to you, since you have to maintain that driver.04:24
infinityI just hope it works "out of the box" for the majoriy of users, and requires tweaking for a tiny subset.04:24
infinityOh, while I'm asking them to give me output proving they're not doing something dumb, "lsmod | grep fb" might be nice too.04:28
infinityUpdated.04:31
=== infinity prepares to click "send" and head to bed...
=== infinity sees a hit in his logs from direcpc, and assumes that's BenC...
BenCyep :)04:37
infinityIgnore the few spelling mistakes (timstamp -> timestamp, etc), I just spellchecked in Thunderbird.  That's all fixed.04:37
BenCbtw, ia64 has vga16fb and vesafb now04:38
infinityJust want to know if the general procedure gets the point across and if you think it'll generate useful reports from otherwise not-always-useful-but-well-meaning users.04:38
infinitySure, but our users don't run ia64.  You can test it for me there, if you want. :)04:38
BenCI'll also test it on my nvidia geforce4 with tvout04:38
BenCcan't yet, waiting for lamont to get my elilo that supports initramfs :)04:38
infinityI thought he already uploaded it to Debian..?04:39

BenCit's not going to be the official one, is it? :)04:44
infinityAlso, I don't expect this to change your tvout situation at all, but I'll be pleasantly surprised if it does.04:44

infinityI don't like the sounds of that.04:59
BenCI don't even see the usplash screen, but my system stays in 640x400-70, and the console works great04:59
BenCbefore vga16fb would break even console04:59
infinityDid you have usplash 0.1-25 installed?04:59
BenCwonder why I don't see it04:59
infinityIf you have -24 or earlier, your usplash will be black.04:59
infinityMaybe I should have made that more explicit in the mail. :)05:00
BenCI have 0.1-2505:02
BenCeven reran update-initramfs -u to make sure05:02
infinityAre you getting a black screen until usplash exits, or n ousplash at all, or..?05:02
infinityWhat do you get if you run "usplash" as root from a console (and wait around for it to timeout and exit)?05:03
BenCblack screen05:04
infinityRather curious about console output after it exits, if any.05:04
BenCseems to timeout on boot05:04
BenCafter it exits I get normal scrolling output05:04
infinityYeah, I mean if you run it manually right now.05:05
BenCthis system is only partially upgraded to dapper (just what the kernel needs)05:05
BenCanything you can think of that I might need to upgrade too?05:05
BenChow long does it take to timeout?05:06
infinityNot off the top of my head.  If usplash is using the right (read: mjg59's goofy temporay) artwork, and usplash is 0.1-25, it SHOULD work.05:06
infinityTimeout if 15 seconds.05:06
infinitys/if/is/05:06
BenCit timed out, and my screen stayed black05:06
infinityRoughly.  The timer seems a bit goofy on some systems.05:06
BenCcan't get console back now05:07
infinitychvt to X and back?05:07
infinityAnyhow, I think this means you and I have a date tomorrow to look into this more.05:07
infinityInteresting that I've fixed your console, but broken usplash.05:08

BenCczr: see topic11:23
czrBenC, the topic didn't answer my question. problems solved though, I built my own git from sources11:26
BenCyes it does11:26
BenCit says to install git-core11:26
czrit says to get git-core for dapper11:26
BenCapt-get install git-core11:26
=== czr is running breezy
czranyhow, problem solved.11:27
BenCif you're building with the 2.6.15 configs, you'll have to be running dapper anyway, atleast a little11:28
BenCbreezy kernel-package will not like some things either11:28
BenCso unless you are doing straight "make" and installing the vmlinuz and modules by-hand, you'll run into trouble11:29
czrwell, I wasn't going to build kernels actually11:29
czrwanted to check whether the ext2online resizing patches are present in the kernel sources or not11:29
BenCthe git repo is not for breezy11:29
BenCbreezy kernel is in baz11:29
czrI noticed. baz?11:29
BenCor just "apt-get source linux-source-2.6.12"11:29
czrok, thanks11:30
BenCyou'll need to enable deb-src line in your sources.list11:30
czryeah, I've been using debian for about 6 years, I think I'll manage ;-)11:30
BenCthen why didn't you do apt-get source to start with? :)11:31
czrsomeone just pointed to the wiki page so I thought that is the way in ubuntu :-)11:31
czris there a nice list of patches applied versus vanilla anywhere?11:32
BenCdebian/patches/11:32
czrthanks11:32
BenCalso, there's a list in /usr/share/doc/linux-image-2.6.12-9*/11:32
czr-10 now I think11:33
BenCFYI, Ubuntu isn't that much different from debian, so whereever you look there, chances are it's the same way on ubuntu11:33
=== czr nods
czrmaybe I'm going the wrong way about it though. the problem is that ext2online doesn't work on breezy over LVM211:34
czrand it works on RHEL4u211:34
czrso I should really look at RH kernel sources first to locate the stuff that they put there11:35
BenCdoes it need a patch to work?11:35
dilingeryes11:35
dilingerrhel has had a patch in there for a while11:35
czrI think so11:35
dilingerit was merged into upstream at some point, i forget when11:35
BenCI'm pretty sure we don't have that patch11:35
czrwell, ext2online fails on breezy, so breezy doesn't11:35
BenCunless it's in upstream, then dapper would probably have it11:35
BenCwhat is ext2online?11:36
czralthough I'm not sure why ext2online fails. All I get is 'resize failed while in kernel' :--)11:36
czrgrows ext2/3 fs:s while they're mounted11:36
dilingerit's an old patch by andreas dilger11:36
czrcomes in ext2resize-package (breezy/univ)11:36
czrdilinger, you sure about the upstream merge?11:37
dilingerpositive11:38
dilingeri remember being very pleased when it happened11:38

czrhmm. would the universe end if I'd build a -15 from vanilla sources manually and install it in breezy?11:40
czrdoes udev need changes, etc?11:40
BenCyou may be missing some devices on your desktop11:43
BenCbut generally it should work11:43
BenCit doesn't take a whole lot to install the dapper kernel11:44
BenCit only updates a few packages11:44
BenCudev mainly, and it will remove hotplug, since it's obsolete11:44
czrah, will all the hotplug helper scripts go too?11:44
BenCyeah, but udev handles it mostly11:44
BenCmay want to add "auto eth0" to /etc/network/interfaces though11:45
czryes, I wondered about that in some distros which have both udev and hotplug scripts11:45
BenC2.6.15 allowed udev to be cleaned up a lot, and hotplug to just disappear11:45
czrah, it's using hotplug. good idea11:45
czrwell, I'll give it a spin soon11:46
czrthe ext2online is really nice feature11:46
