smbmorning .+07:12
ppisatismb: i'm looking @ your comments for 108207:41
smbThanks for letting me know. ;)07:46
ckingmorning too07:46
smbonly one more in this tz07:47
ppisatidid apw already leave?07:53
smbppisati, Usually not as long as ckins is here07:53
ppisatiah ok07:54
smbppisati, But you remember him leaving for the pub yesterday... >:-)07:54
ppisatiuhmmm... are you implying he could still be there? :)07:55
smbUnlikely with the way English pubs close down. Rather implying some after-effect. :)07:56
ppisatiah right, i keep forgetting the bell07:56
ckingppisati, apw is flying out tomorrow08:04
smbcking, likely in the seat next to you I assume. :)08:05
ckingunless BA mess up08:05
smbOr goes on strike...08:05
* smb read about AF strike and hopes the AF marketed DL flight he is on will be unaffected08:06
* ppisati ponders goig to the post office...08:16
* ppisati stops ponderating and goes... back in a bit08:27
* apw didn't leave, just feelig very well today08:46
smbnot?08:46
apwindeed08:47
* smb hopes it wasn't the one apw had to drink for him08:47
apwheh no, nothing like that08:47
smbOh good... and bad08:48
smbapw, Try to recover. There is enough pain tomorrow08:48
sorensmb: Travel?08:51
smbsoren, Yep, its that time again. :)08:51
sorensmb: Indeed. I hope Air France isn't involved in your trip?08:52
smbsoren, It is at least for selling the flight. Its operated by Delta. I hope that helps me to get there08:52
sorenProbably.08:53
apwwith the number of people coming, it'll affect somewone08:56
apwmay even trap some at ELC08:57
sorenapw: What's ELC?08:58
smbAt least there is something flying and not nothing like when the volcano stroke08:58
apwits not quite elc, the embedded thing thats going on in budapesht or somewhere like there08:58
smbapw, kernel summit even?08:59
sorenOh, it's an event. Got it. I thought it was an airport code I didn't know :)08:59
apwahh sorry, i can see how it might seem to be one of those09:00
* ppisati has just bought a ton of paracetamol...09:59
jk-ppisati: preparing for UDS? good plan. :)10:36
ppisatippisati: well, actually i've a cold... really... :)10:36

rockyhey can anyone help me in kernel debugging?11:46
apw_its best to just ask your question or describe problem, as dfferent people have different spcialisms11:48
apw_rocky ^^11:51
ppisatismb: so, in the end, where do we meet at the airport?12:56
smbppisati, I'd suggest the fountain on level 3 of the main terminal building. Lacking any real feedback there12:57
smbIf you find the people travelling with you, you can try dragging them along12:57
apwsmb, meeting this end or that :)13:04
=== zz_bigbash is now known as bigbash
smbapw, hard to say with a round fountain... :-P But I guess you meant her or over there. So in Orlando. :)13:05
apwahh you guys landing similar times, cool13:05
smbYep, there seem to be a few more on his plane, but only one answered to email and did not confirm anything after I proposed the fountain instead of the food court in favour of likely less cramped space13:07
smbSo maybe only  the two of us will meet13:07
ppisatismb: fountain, level 3, main terminal, ack13:08
ppisatismb: i'll drag my butt and my virus over there :)13:08
smbppisati, I would not mind if you lost the virus while walking there... :)13:09
ppisatismb: i'll try, but i can't guarantee :)13:09
ckingsmb, you gotta cold?13:10
smbcking, Not *me*13:11
smbOr not xyet13:11
ckinglooks like we arrive at level 3 and the shuttle bus is on level 113:11
smbHearing all those wonderful announcments of cold, stomach bugs and coughs, I am not sure about after the event13:11
ppisati:)13:12

tgardnersconklin, when is the next packaging cycle for Hardy ? I want to wait on any major packaging changes until a logical time, plus I'd like to talk to Andy about his ideas.13:35
apwcking, you are assuming it will be nice.  2-5 inches of rain forcast for sunday13:36
ckingreally?13:36
tgardnerholy smokes. 2-5 ? that is a bunch.13:36
ckingBetter pack a mac13:36
apwoh thats over the weekend and "into early next week" -- so a 3-4 day period13:37
apwcitainly a raincoat in your packing is essential13:37
tgardnerat least its pretty warm13:38
apwtgardner, isn't that brad and herton's bag now13:38
tgardnerapw, bjf doesn't start until after UDS IIRC13:38
apwahh13:38
tgardnerand herton is on vacation13:39
apwman a 60% chance of rain on saturday, 10% on sunday, 50% on monday ... 13:39
apwnot going to be as nice as last time by a long way13:39
ckingsad trombone13:39

sconklintgardner: we're about to wrap up a cycle for the kernels, except that Oneiric has a regression we're still bisecting.14:21
sconklinwe can either crank out a new hardy with the patches in -next and start the refactor fresh, or hols with what we have14:22
sconklins/hols/hold/14:22
smbsconklin, Does that include a Lucid one?14:22
sconklinLucid is currently awaitign copy to -updates, so it has passed everything and is done as far as we care for this cycle14:23
sconklinhttp://people.canonical.com/~kernel/reports/kernel-sru-workflow.html14:23
smbAh, ok, well then I have enough time to come up with the reverts I just found to be helpful (has been around since the previous update anyway)14:24
sconklinAnd just because this is a good time to post the link again, there's a wealth of information in these reports:14:24
sconklinhttp://people.canonical.com/~kernel/reports/14:24
sconklinsmb: sounds ok14:24
apwsconklin, the regression under bug #880476 sounds a lot like a grub change, as it is no longer using UUIDs14:36
ubot2Launchpad bug 880476 in linux "after update to kernel 3.0.0-13 ubuntu 11.10 does not start" [High,Triaged] https://launchpad.net/bugs/88047614:36
apwsconklin, note it is using root=/dev/sda7 on the -13 boot entries, but UUID=xxx on the others, that seems wrong to me14:37
sconklinapw: and did you see the last entry from the reporter?14:40
apwsconklin, that is an odd message, and makes me worry about his while initrd on that machine14:41
apwi'd love to see him try booting with root=UUID=xxx from the -12 image14:42
sconklinyes, I'm not sure what to tell him. I think that he has problems beyond the 13 kernel14:42
sconklinapw: feel free to update the bug or I can. The more the merrier14:42
apwmy uptodate machine with -13 is still using the UUID= form14:42
apwso its not a generic change14:42
apwsconklin, done14:46
sconklinapw: it is strange - I wonder if this is going to be one of those "well, I did change something" bugs14:49
apwsconklin, yeah well he even says he notes that the grub entry differs14:52
apwcjwatson, is there a common cause of grub switching from using root=UUID=x to root=/dev/sda7 style notations ?14:53
jwibug 862121 seems to report the same issue after upgrading from -11 to -1215:03
ubot2Launchpad bug 862121 in linux "Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" [Undecided,Confirmed] https://launchpad.net/bugs/86212115:03
slangasektgardner: so we have some debugging logs from the initramfs now on bug #842560, and it's making me scratch my head... the kernel is asking for the firmware to be loaded and unloaded twice, for each card?15:25
ubot2Launchpad bug 842560 in linux "bnx2 firmware missing" [High,Confirmed] https://launchpad.net/bugs/84256015:25
tgardnerslangasek, yes, each adapter will request a firmware file. even though its the same driver, the adapters may require different firmware files depending on model.15:28
slangasektgardner: yes, but I'm seeing two load/unload events for *each adapter*15:28
slangasekfor the same firmware file15:28
slangasekthat looks screwy to me15:28
tgardnerslangasek, as far as I can tell from the source the firmware file is only requested once per adapter15:29
tgardneryou're sure your debug is correct ?15:29
slangasektgardner: I'm sure the debugging is what udev is seeing from the event queue15:29
slangasekthis is the output of 'udevadm -e monitor', launched before udevd in the initramfs15:30
tgardnerslangasek, apw is a bit more familiar with this sequence as he helped debug the last time we had udev issues. apw - are you around ?15:31
tgardnerslangasek, could it be asking for a version that doesn't exist? Some of the wireless drivers at least support multiple firmware versions and kind of walk down the list until they find one.15:35
tgardnerguess I could look at the log myself15:36
slangasektgardner: unless I've gone cross-eyed, the requested file is one that does exist; and it does seem to get loaded the first time around15:36
apwhmm15:37
apwslangasek, there only seem to be 4 sets of add remote, two pairs per firmware file, which would be like one per adapter15:41
apwone *set* per adapter15:41
slangasekapw: how many adapters are you seeing?  I see only two: /devices/pci0000:00/0000:00:02.0/0000:06:00.0/0000:07:00.0/0000:08:00.0/0000:09:00.0, /devices/pci0000:00/0000:00:1c.0/0000:04:00.0/0000:05:00.015:43

slangasekapw: that's not the doubling I'm talking about15:43
apwnote the KERNEL and UDEV prefixes15:43

slangasekyah15:46
slangasekok15:46
apwright the card has two lots of firmware15:46
slangasekbut what are the removal requests for?15:46
slangasekit decided it didn't like the firmware after all?15:46
apwas i understand ti the firmware device only appears for a short period while the firmware is needed15:46
slangasekah15:46
apwand the goes away, the firmware remains in memory15:47
apwi beliebe the remove effectivly tells us the load completed15:47
slangasekright... but then after all is said and done the kernel is saying it was unable to load the firmware15:47
slangasekseems like a bug on the kernel side to me15:48
slangasekbecause we're seeing complete pairs of add/remove for each firmware file on each adapter15:48
apwwell that just means the load 'completed', it doesn't mean that it was successful15:48
slangasekyes, but if the load completed, that means it's no longer udev's problem, doesn't it?15:48
apwdepends how 'ending load' is detected, and load complete might mean load went all horribly wrong15:49
apwi assume the second load here failed ?15:49
apwas normal ?15:49
slangasekthe kernel "couldn't load firmware" error isn't happening for 60 seconds *after* these events15:49
slangaseki.e., when udev gets tired of waiting and kills off the modprobe15:49
slangasek"as normal"?  It does appear to be the second load that's failing15:50
apwthe complaint is that the second card only fails15:50
apwand you added debug so i was making sure this debugged version failed too15:50
slangasekah, I don't have the corresponding dmesg for this run, sorry15:51
* slangasek requests it on the bug15:52
* cking packs up for UDS..15:52
apwslangasek, do we even know it failed as this udev shows eth0 and eth1 queues appearing15:55
slangaseknope15:55
slangasekhence, requesting moreinfo on the bug15:55
apwslangasek, thanks, i am suspicious this is a timeing issue and your debug may have fixed it15:56
slangasekheh15:56
slangasekyeah, let's see15:56
tgardnerapw, see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/882120/comments/3. Perhaps linux-image-extra-virtual needs a postinst rule.16:24

apwtgardner, possible indeed16:25
tgardnerhmm, I wonder why LBM works 16:25
apwi'll take a look, i may have missed something there16:25
tgardnerapw, LBM has debian/rules.d/3-udebs.mk: /sbin/depmod -b $(udebdir) $$i; 16:26

apwyeah ... just finished packing; have an engagement party to go to tonight, so i expect the flight will be excruciating16:27

tgardnertyhicks, there is a key signing party scheduled weds (?) night I think. at any rate, we can do it informally during UDS18:01
