kylembenc. ok. i found the problem.01:37
kylembut my wireless crapped out before i was able to mention it.01:37
zulaiie....slow close01:39
kylemfuck, and it is crapping out now.01:43
zuli blame the westin01:44
zul...and i should be there tomorrow01:44
kylemnice.01:45
kylemBenC, would it help if i fed you parisc patches? i can probably pretty easily automatically populate a tree.01:45
BenC_kylem: If I can git-pull them against 2.6.17.x, then yeayh01:46
BenCor against a clone of the ubuntu git tree01:47

=== kylem [n=kyle@cabal.ca] has joined #ubuntu-kernel
BenCso what's the problem?01:54
kylemyou pulled the async scsi scanning stuff from the parisc tree. unless scsi is built into the kernel (so it can be __init) it won't pause and wait for the async scan to complete.01:54
kylemi'm genning a diff to revert that bit.01:55
kylemotherwise there's a bit in cvs now that gives you a module to load.01:55
kylem(it's designed to be the last thing the initramfs loads, and waits for scans to completE)01:55
BenCoh really?02:13
BenCthat'd be interesting...Kamion would actually like it so he doesn't have to load ide_generic in weird ways02:14
BenCbut that doesn't solve the problem of our current config not even getting serial output02:14

pmjdebruijnwhy does the dapper kernel break when compiled on Debian?02:19
bernard_pmjdebruijn: i suspect it broke because acpi is not enabled02:25
pmjdebruijnbernard_, yeah, right... but that should be considered a bug right?02:26
bernard_yup. i guess ubuntu kernels are rarely compiled with acpi off. it should be a trivial fix though. if you look inside arch/i386/kernel/setup.c, the call to check_acpi_pci() just needs to move inside the #ifdef CONFIG_ACPI block.02:32
pmjdebruijnhmm right02:35
pmjdebruijnit's already surrounded by a #ifdef CONFIG_X86_IO_APIC02:39
bernard_yes. it needs to go inside CONFIG_ACPI also.02:41
=== Keybuk [n=scott@quest.netsplit.com] has joined #ubuntu-kernel
pmjdebruijnbernard_, ok, will do02:49

fabbioneare headers still broken on sparc?05:04
MithrandirBenC: freeze is over now, so you're free to upload your kernel stuff.05:05
BenCMithrandir: thanks05:05
BenCfabbione: shouldn't be05:05
fabbioneBenC: looks like we are still missing headers....05:06
makxKeybuk: any conterargs if i kill of the prereqs stuff in initramfs-tools?05:13
Mithrandirmakx: uh?05:13
Keybukmakx: I've always thought it was silly, as it wastes time on boot ... I always thought we should just assemble it in the right order at update-initramfs time05:14
Keybuk*BUT* jbailey will point out the initramfs is supposed to be runtime assembled05:14
Keybukwhich is why you need the PREREQS05:14
makxKeybuk: what about numerical order aka 05evms 10md 20lvm 90cryptsetup05:15
Keybukit's allegedly less flexible05:15
makxprereqs has no easy way to be first or last05:15
KeybukI was actually mulling the idea of maybe replacing the initramfs init with upstart ... ;)05:15
makxprereqs wasts boot time and hinders klibc only plan05:16
makxwhat is upstart?05:16
zulBenC: ill send you the patch tonight for kernel-package its a very small patch05:17
makxalso lots of script writer get-their.name-totally_wrong05:17
BenCfabbione: Actually, it looks more like sparc headers are just broken05:20
fabbione<fabbione> are headers still broken on sparc? <-05:20
fabbione:)05:20
BenCfabbione: the include for those headers should probably be wrapped in __KERNEL__05:20
BenCactually, why is ocfs2 including page.h anyway?05:21
BenCon all other arches, it is an empty file05:21
BenCin lkh at least05:21
fabbioneBenC: no idea05:22
fabbioneit was building before05:22
makxKeybuk: google doesn't give hints on upstart? -v 05:24
Keybukhttp://wiki.ubuntu.com/ReplacementInit05:24
Keybukmakx: why do prereqs affect klibc-only?05:24
BenCfabbione: I'd edit mount.ocfs2.h and remove the asm/page.h include05:24
fabbioneBenC: can you make sure that's the right thing to do?05:25
BenCfabbione: nm, I see the problem...it'll be fixed in the next upload05:25
fabbioneok05:26
fabbionethanks05:26
BenCthat actually is the right thing, but I can work around it05:26
fabbionewell if it's the right thing i can do it05:26
makxKeybuk: basename usage - thought to get rid of both as prereqs is flacky05:26
fabbionei am just on the edge every day to leave stuff in proper order05:26
BenCfabbione: it's the right thing, but I'm not sure it will work :)05:27
makxKeybuk: btw thx for the doc05:27
fabbioneBenC: exactly :)05:27
Keybukmakx: it's intended as our replacement for /sbin/init in the real root ... but for edgy+1 it may make some sense to start it in the initramfs instead <g>05:27
pmjdebruijnanybody here a clue why this fails: http://paste.ubuntu-nl.org/1843705:28
=== BenC [n=bcollins@debian/developer/bcollins] has joined #ubuntu-kernel
fabbioneBenC: it looks like we will need to go and dig into GFS2/GFS failures. According to upstream it works for them and it fails with our kernel05:35
BenClamont: ping05:35
makxKeybuk: there is an side issue not mentioned in this spec, usually when you upgrade a Debian box you find lots of devices running that weren't before05:35
Keybukmakx: "devices running" ?05:36
makxKeybuk: sorry to warm s/devices/services/05:36
pmjdebruijnoh silly me, it's because of the extra tag05:36
Keybukmakx: right, upgrade brings in new services ... ?05:37
BenCwell, it might bring in new devices too :)05:37
BenCipw3945 comes to mind05:37
makxKeybuk: no postinst brings new service that wasn't running before upgrade05:37
KeybukBenC: if an upgrade to etch upgraded my atheros to an ipw3495 I'd be impressed05:37
Keybukmakx: oh, right ... the way a postinst starts a service you explicitly stopped05:37
BenCah, I thought you meant general upgrades05:38
makxKeybuk: yup05:38
pmjdebruijnbernard_, thanks for the help, I posted it: https://launchpad.net/bugs/5353305:39
bernard_pmjdebruijn: looks good! ta.05:43
