fabbioneBenC: hey dude.. usual pull from my branch :)03:31
BenCok03:31
BenCzul: you got anything for me?03:31
fabbioneBenC: more SUN4V merges and i did bump B-D on kernel-package to fix a frigging annoying problem with sparc32 dpkg-buid... sparc64 dpkg-build..03:31
fabbionekernel-package is of course already in archive03:32
BenCfabbione: ok03:32
zulBenC: yeah i ll email you the patch tonight03:32
fabbionethanks dude...03:32
BenCnp, thanks03:32
fabbioneBenC: i also noticed a missing symbol building a scsi driver..03:32
BenCsym2 scsi driver?03:33
BenCoooh, yeah, I see it03:33
BenCthat's bad03:33
fabbioneyou should have the message on the other chan03:34
zuli almost have my quietboot patch ready for grub03:34
fabbioneyes03:34
fabbionei saw it on sparc03:34
fabbioneno idea on other arches03:34
fabbionebut i think it's the same03:34
=== Yagisan [n=jamie@60-240-127-178.tpgi.com.au] has joined #ubuntu-kernel
BenCah, it's on sparc64, but it isn't EXPORT_SYMBOL so modules can use it03:35
fabbioneok :)03:36
fabbionei didn't really have the time to check03:36
BenCeasy fix, I'll get it in03:37
doko_jbailey, BenC: interesting for ia64 only. which linux-kernel-headers package shoudl be included in ia32-libs-dev? currently there is linux-kernel-headers_2.6.11.2-0ubuntu16_i386.deb03:40
jbaileydoko_: The word I got from the folks at HP is that newer itanics don't do ia32, and therefor we should drop ia32 compatability.03:40
jbaileyThat's why lkh doesn'thave the multiarch stuff in it for ia64.03:40
doko_so should we drop it still for dapper?03:41
fabbionehmm spanking of ia64..03:41
fabbionelet's look at that udev/kernel boot problem03:41
Keybukwhich one is that?03:42
fabbioneKeybuk: i saw udevplug segfaulting while parsing /sys03:42
fabbionethe result is that no modules are loaded...03:42
fabbionebut i didn't have time to dig it03:42
fabbione(found it yesterday)03:42
fabbioneKeybuk: don't worry.. i will come back to you, if the bug is udev :)03:43
BenCmy ia64 boots fine03:43
=== fabbione modprobes Overfiend.ko
BenCno segv's that I saw03:43
Keybukif it's a udevplug segfault, then it's likely a udevplug bug anyway03:43
Keybukit shouldn't SEGV03:43
fabbioneBenC: you told me yesterday that it didn't boot?03:43
Keybukgimme a backtrace03:43
fabbioneKeybuk: in a sec.. firing up console...03:43
BenCfabbione: that was a hw issue it seems03:44
doko_jbailey: I still leave it in for now03:44
BenCfabbione: anyway I can try to reproduce?03:44
jbaileydoko_: Sure, I'm not fussed.  That's just why I didn't do it.03:44
fabbioneBenC: i am booting my box now03:45
fabbioneBenC: it looks like a kernel problem..03:48
fabbionelet me check if it is the last one03:48
doko_jbailey: that would let us reduce ia32-libs to a more sane size03:54
BenCdoes ia64 need to bufforce udev?03:57
BenCneed the03:57
fabbioneBenC: no i don't think so03:57
fabbionethe patch was for alpha/sparc/hppa03:57
BenCgreat, my ia64 doesn't appear to be rebooting03:57
fabbioneit's kernel bug03:57
=== BenC wonders if it suffered the sym2 bug he just fixed in sparc
fabbioneintroduced between -15- and -16-03:58

fabbionei am taking a trace now03:59
BenCis there a kernel message?03:59
BenCwow, ia64 has too man registers04:00
BenCany idea what file it is?04:01
fabbioneBenC: see /msg04:01

fabbionei can probably get to console04:02
fabbioneif there was a frigging find in busybox...04:02

fabbionethe scsi driver loads fine..04:03

zulhell ill just send the patch now...BenC you have new email...you bastard04:19
fabbioneBenC: did you build your kernel from git?04:19
BenCfabbione: of course :)04:19
BenCzul: thanks biatch04:19
fabbioneBenC: that might be why04:19
fabbionei think the bug is in the scsi driver04:20
BenCfabbione: because our git repo is the almighty accumulation of stability? :)04:20
BenCwell, sym2 is updated in our repo04:20

remonI've a question about an alsa driver, but I think it's also related to the kernel (2.6)04:55
=== CataEnry [n=cataenry@host83-39.pool8248.interbusiness.it] has joined #ubuntu-kernel
remonthe echoaudio driver is in the alsa-driver package from 1.0.8rc2, but not included (don't know for some specific reason) in the kernel source. It would be lovely if the ubuntu kernel are compiled with the echoaudio drivers included too!04:57
fabbioneremon: please file a wishlist bug on malone. http://launchpad.net/malone04:59
fabbionecomponent: linux04:59
remonfabbione: thanks, will do so! 05:00
remon(trying now myself to build an ubuntu kernel with the echoaudio driver added to the kernel source, does it help if I report the results? )05:00
fabbioneit helps if you provide a non intrusive patch05:01
remonfabbione: I'll see if I can make one, if it works of course.....05:02
remonhmm, I'm having a bit trouble with using launchpad: "No revision control details recorded for 2.6.15 "05:12
remonit seems the linux kernel aren't (yet) managed by launchpad ?05:12
zuli think you might want linux-source05:13
remonzul: thanks, will try that one 05:14
remonI'm only able to find this one: https://launchpad.net/products/linux05:15
remonand there are bug reports etc, but for some reason it complains with the above message05:15
remonah, found the correct page, filling a report now! :)05:16
BenCremon: file a bug and mark it for Ubuntu and the linux-source-2.6.15 source package05:22

mjg59Thanks10:06
mjg59BenC: Why is -386 CONFIG_SMP=n?10:16
mjg59It means I'm only getting one core up with the install kernel10:17

fabbionemjg59: on -server yes10:21
mjg59This isn't a server10:22
fabbionedon't think so on desktop10:22
mjg59So an installed system won't end up with SMP. Hmm. That seems less than ideal.10:22
fabbioneit was the same as warty/hoary/breezy10:22
fabbionethere is no way to stick another kernel on the CD10:23
mjg59But we could shift the -386 kernel to be SMP now10:24
mjg59Since there's no performance hit10:24
mjg59But there /are/ an increasing number of dual-core systems on the market10:25
mjg59Hmm. It's slowed right down. I wonder why.10:25
mjg59I suspect overheating, but it's hard to tell...10:25
mdzwe've had problems in the past with SMP kernels on UP systems; I think we ought to wait until after dapper10:26
