apwdiwic, hi07:36
diwicapw, you're the maintainer of checkpatch, aren't you?07:55
diwicor at least a frequent contributor07:55
apwdiwic, indeed07:55
diwicapw, I'm getting what I think is a false positive07:55
apwdiwic, you won't be the first :)07:56
diwicapw, could I send the patch to you to double check that I'm not completely stupid?07:56
apwof course07:56
diwicapw, sent07:57
brendandcking - hi08:24
ckingbrendand, hiya08:24
brendandcking, i just have a new data point for you in the fwts/suspend saga. you know the device-check can be foiled by xinput reordering the list of devices?08:25
brendandcking, everything's still there, but swapped around08:25
brendandto illustrate : http://paste.ubuntu.com/1062206/08:26
ckingbrendand, nope, I didn't know that, I'll filed a bug and get that sorted out08:26
ckingbrendand, I suggest not using the --s3-device-check flag until the fix lands in V0.25.0508:33
brendandcking - thanks for looking at it08:38
ckingI'm working on a fix right now08:38
ckingthanks for identifying this issue -  looks like it's not been exercised much08:39
brendandcking, thanks for looking at it. one of the advantages of having such a wide variety of hardware at our disposal is that we have the 'privilege' of finding out about all the quirks09:08
ckingyep, I've only tested it on ~5-10 machines here09:08
apwxinput reordering its inputs through suspend, fun ... i bet its usb things which move09:09
ckingI overlooked this - doh09:09
brendandcking, to be honest, there's so much stuff going on that you can overlook that it's not worth worrying about09:10
brendandjust have to take them as they come09:10
ckingyep, thanks for spotting this, I've got a fix written now, just testing it..09:11
brendandcking, what i don't understand is that the id stays the same, so why doesn't xinput just id order?09:14
ckingbecause it likes to make our lives difficult?09:14
brendandcking, that's the correct answer! you win a prize09:14
dhana013Hi Guys, I have doubt in 32 bit linux kernel and 64 bit linux kernel09:23
dhana013my machine already working with 32 bit kernel. I have 64 bit kernel , I change my kernel as 64.09:23
dhana013bit, it's possible do this. I can do install 64 bit packages 09:24
dhana013please guide me guys09:40
apwyou can in theory install a 64 bit kernel on an i386 userspace if it has 64bit support in the CPU09:41
apwdepending how much ram you have its not always a good idea though09:41
apwcking, does the 'you may wish to read the release notes' link for work you on the installer?n09:42
cooloneyapw: hey, andy, i'm going to start to do config review for common ARM drivers09:53
apwcooloney, ok sounds "fun"09:54
cooloneyapw: so a silly questions, actually what's common ARM drivers config or where is it?09:54
cooloneyapw: is it the common config file for armel and armhf?09:54
apwheh ... thats a question, finding out whats 'h/w' specific options is pretty hard09:55
apwi have never approached commonising config from that side just for that reason09:55
cooloneyapw: hah, i just start and found it's hard to find them indeed09:56
cooloneyapw: but i saw your email several weeks about ARM config. 09:56
apwwell i was fighting arm configs which differed in non-arm things, things like filesystems, right ?09:57
ppisaticooloney: you'll find a lot of arm (and even omap-only) related crap even in config.common.ubuntu09:58
dhana013apw, I have i5 processor in my machine how to configure custom kernel please guide 09:59
cooloneyppisati: oh that's bad09:59
cooloneyapw: i remember some USB host configs were mentioned in your email09:59
dhana013how to utilize the hole hardware to my linux kernel 10:00
ppisaticooloney: yes it is, unfortunately10:01
ppisaticooloney: it would be nice if we could push all the hw-agnostic stuff in config.common10:01
ppisaticooloney: and leave arm details in config/<arch>/config.*10:02
ppisaticooloney: but i think it's a lot of work, and a lot of shuffling stuff around10:02
ogra_but it will make the future so much easier :)10:02
ppisatiyes, but whenever i moved any option out of that file, it reappeared in all the arch specific config file after an updateconfigs10:03
cooloneyi didn't imagine the work is so hard before10:04
ppisatii think the logic is someghing like "can i have that option? good, then i put it in config.common"10:04
ppisati"is that option any different in any ach specific config file? cool, then i remove it from config.common and push it one level down"10:05
ppisatii think the real problem is *why* arm and omap specific options are not binded to any CONFIG_ARCH_ARM or stuff like that10:05
ppisatiin that case they won't appear in config.common i guess10:05
ppisatiso the proper fix is to make an arch specific option depends on another arch specific option that only appear in an arch specific config file (this way updateconfigs won't push it inb the config.comm file)10:06
ppisatii hope i got it right...10:06
ppisatisomehow...10:06
cooloneyppisati: oh wait, looks like this is an updateconfigs script issue10:07
ppisaticooloney: no no10:07
ppisaticooloney: wait, let me show you an example10:07
cooloneyppisati: yeah10:07
ppisaticooloney: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-quantal.git;a=blob;f=debian.master/config/config.common.ubuntu;h=40c77e1f9a2a8f7c8ac49edb19ac55cecdc19e82;hb=HEAD10:10
ppisaticooloney: take for example an omap option10:10
ppisaticooloney: like...10:10
ppisaticooloney: CRYPTO_DEV_OMAP_AES10:10
ppisaticooloney: it shouldn't be here10:10
ppisatisince it's arm (and even omap in this case) specific10:11
cooloneyppisati: yeah10:11
ppisatiso it should go in config/arm[hf|el]/config.flavour.omap10:11
ppisatinow, if you move it here, ALL the other other configs file will get this option replicated10:11
ppisatilet me try...10:12
apwcooloney, ppisati, the config optimiser takes no account of which arch something ocmes from as it does not really know10:12
cooloneyppisati: I know what you mean here now. 10:12
cooloneyi found 11 OMAP config in common.ubuntu config10:12
apwand its dangersous to try anyhow because armhf and armel are 'separate' configuration options10:12
apws/options/arches10:13
apwbut they need to be mostly common10:13
apwcooloney, any specific option being in common.ubuntu just means it has a common setting in all configurations for which it is present10:13
apwwhere something is in the config hierachy isn't important really, whats important is when its set it is set appropriatly10:13
apwwhich is where the configuration checker comes in10:14
apwhttps://wiki.ubuntu.com/KernelTeam/Specs/QKernelConfigReview/Alpha210:14
apwwhich is what we use to review and fix options normally10:14
apwCONFIG_CRYPTO_DEV_OMAP_AES if you look at that one for instance, it is m on omap and - on everything else, so that is ok and we don't care where it goes in the hierachy10:16
cooloneyapw: right, so if an option is the same for all arches, it goes into top common config10:17
apwyes it will roll up to th10:17
apwto the top10:17
cooloneyapw: and if is the same for all the armhf arch, it goes into common.armhf.config.10:18
apwif tis the same for all armhf configs but not for other arches, then yes its in common.armhf only10:18
cooloneyppisati: so as apw said, some OMAP configs in common.ubuntu.config show up because they are the same for all the arch configs10:18
apwright and that is expected, its a side effect of the algorithm10:19
cooloneyapw: yeah, exactly10:19
apwto be honest its utilitity, the commonisation is less important now we have a proper config comparitor10:19
apwas the human can look at the rows in the wiki much better than understanding where in the config hierachy an option ended up10:19
ppisatiwhat i wanted to say is that, it would be nice to have options separated by their usage: common non-arch specific options go in config.common, armhf specific go in armhf/config.common.armhf, omap-only options go in armhf/config.flavour.omap, ectect10:21
ppisatithis way adding a new flavour equals adding a new config leaf10:21
ppisatifile10:21
apwppisati, that would be nice, but thats not quite how it works10:21
ppisatie.g. armhf/config.flavour.highbank10:21
ppisatiapw: yes10:22
apwppisati, generally to add a new flavour you can just dump a full config down in that file10:22
apwand fdr updateconfigs will clear out the common stuff and make a mess of the configs of course10:22
ckingapw, re: installer, not yet got around to that, will be testing in 20 mins10:22
ppisatiapw: i think i did during the omap4 review (and last omap3 config bisection)10:22
ppisatiapw: and updateconfigs badly messed up the config10:23
ppisatianyway10:23
ppisaticooloney: in any way, have fun! :)10:23
apwppisati, well yes if your config is differnt it has to change the balance to maintain your config10:23
ppisaticooloney: sun is shining, it's summer time, and all that solar crap... :)10:23
apwppisati, it doesn't override any of the configs, which is what you want10:23
ppisatiapw: i don't know, maybe i had a dream/nightmare10:24
ppisatiapw: but during the...10:24
apwi have a bunch of overrides documented now though for next time, which i did to fix highbank up10:24
ppisatiapw: 3.5 rebase, to me it looks like omap3 "imported" some options that weren't there before10:24
apwas from an ubuntu commonisation point of view its the non-arch crap i want right, the h/w stuff should be board specific10:24
apwppisati, well if you took the non-3.5 config and used that yes, you should really have put the config a 3.5 tree and did make oldconfig on it first10:25
apwto get asked about the new things10:25
apwthen used that one in the ubuntu tree10:25
ppisatiIMVHO we could drop updateconfigs, and mantain config.common manually10:26
ppisatiapw: could be, don't rememebr when i had that impression10:26
ppisati(but i know it won't happen)10:26
apwppisati, the utility of updateconfigs for changing configs is less than it was10:27
apwnow we also have OVERRIDES to inject changes across the board10:27
apwgetting from where we are to where you suggest is very hard, but it would be a better place10:27
ppisatii know, a lot of shuffling around10:28
ppisatiand you can't do that in one pass10:28
ppisatiit's an iterative process10:28
apwppisati, the biggest issue is there is hierachy we cannot express currently like10:28
apwubuntu -> arm -> armel/armhf10:28
ppisatiright10:28
apwand till we can do that its tricky, and the layout of the configs is tied to other layouts currently10:29
ppisatiwell, truth be told that's becasue we use ABIs instead of arch10:29
ppisatiare we going to support...10:29
apwso its not easy.  but i will think on it as what you want makes a lot of sense, its what we all want10:29
ppisatithe 32/64 bit hybrid10:29
ppisatiwhat was the name...10:30
cooloneyapw and ppisati, i think basically i can start that from the URL for kernel config review. 10:30
ppisatin3210:30
apw"ubuntu needs X" "x86 needs Y" "x86/server needs Z"10:30
apwcooloney, yep anything you find out of sync _either_ needs making in sync, or you need to let me know so i can annotate it as correct10:30
apwfor example arm needs vfat builtin and thats right, so it has an annotation10:31
ppisatino, it's not n32...10:31
cooloneyapw: sure, i will and try to change the status of this task from TODO to IN PROGRESS 10:31
ppisatix32!10:31
cooloneyapw: and can never mark that as DONE. heh10:31
apwcooloney, which task?10:31
cooloneyapw: review common drivers for ARM10:32
ppisatihttp://en.wikipedia.org/wiki/X32_ABI10:32
ppisatithis one would use 64bit regs in a 32b address space10:32
apwcooloney, sounds good, and even a rough pass is better than nothing10:32
ppisatii don't think we are going to support it10:33
apwppisati, yep its probabally what amd64 should have been10:33
ppisatibut in case we do, we will find ourself in the same situation with armhf/armel10:33
ppisatiwith x32 and i38610:33
cooloneyapw: np, 10:33
apwppisati, indeed, well we already are, as i386/amd64 already has this commonality10:33
* apw will play with that before sprint10:34
cooloneyppisati: so the first one, why CONFIG_MSDOS_FS should be =y instead of =m for omap4?10:34
apwcooloney, we have vfat_fs set for the other arm ones but not msdos_fs, but only someone with the h/w would know if that is needed or not10:36
ppisaticooloney: because, for example, if you install a new kernel with same rev as the old one (3.5.0-666~foo will put modules in /lib/modules/3.5.0-666 just like the original 3.5.0-666 would do)10:37
apwppisati, is that msdos or vfat though, we have vfat builtin on omap3 et al for that purpose, perhaps they are wrong?10:38
ppisaticooloney: but if the old one has no dos/8859-1 support compiled in, you will end up with modules overwritten (so no chacne to load msdos support) and no ability to mount /dev/mmcblk0p1 where uImage should be copied10:38
cooloneyppisati: but for omap3 we use =m as others10:39
ppisaticooloney: don't we have vfat set?10:40
apwppisati, we have VFAT_FS set for all arm ports, we have MSDOS_FS set on ti-omap4 only10:40
ppisatiah10:40
ppisatiso it's a mistake10:41
apwso i suspect we either need both on all or only vfat on all10:41
cooloneyppisati: VFAT=y for all arm stuff, 10:41
ppisaticooloney: that should be...10:41
cooloneyVFAT=m for others like i386 and amd6410:41
ppisatibtw10:41
ppisatiso what's the diff between vfat and msdos? fat16 vs vat?10:41
cooloneyso i think MSDOS_FS should be =m for omap4, right?10:42
ppisatii thought they were synonyms10:42
apwdifferent drivers indeed.  someone needs to investigate which we needed really on all of them10:42
cooloneyppisati:  vfat will allow you to use long file names.10:44
ppisaticooloney: got for vfat then10:45
cooloneyppisati: yeah, i guess built in VFAT is enough, but not sure right now10:47
apwcking, smb, do the indicator menus look ok to you, about half of mine have wrong colours10:47
apwppisati, can you not work out which one is in use by looking at the mount once mounted10:47
smbapw, not far enough yet to see them...10:47
apwsmb, also got a jockey popup to offer me drivers, which appears to have done so to offer me 'pc speaker'10:48
smbapw, I assume you speak of quantal...10:48
apwsmb, indeed is it not ISO testing day10:48
smbapw, It is. Just my alternate vm installs are not far enough for gfx10:49
smbThe kubuntu on real hardware is doing bad enough not to be able to autoreport bus and the server install on that laptop fight s with enabling b4410:49
smbJust one of these days...10:50
cooloneyapw, smb, cking and ppisati, do you guys know where will we stay durning our portland sprint?10:50
cooloneyor not decided yet10:50
ppisaticooloney: nope10:50
ppisatibrb10:50
smbcooloney, We assume but do not know for sure10:51
* ppisati -> out for lunch11:06
apwppisati, can you tell me which of the two hdmi ports on a panda is the right one?12:17
apwppisati, have you tested the omap4 images for A2, i am struggling to get output from them, even though they seem to do the right kind of booting 12:23
apwppisati, also do i expect to see anything serial side?12:27
ogra_apw, i have the same issue12:36
apwogra_, ok so no output on hdmi then?  which port is normally live12:36
ogra_apw, bug 101000912:40
ogra_no output at all on many monitors12:40
ogra_i found a workaround for mine though12:40

ogra_apw, works here 12:41
ogra_in the DVI port with hdmi->dvi cable here 12:41
ogra_ppisati, bah, the penguins are back !12:42
apwogra_, if i want to change the kernel comamnd line can i do that somewhere either on the image or the serial ?12:42
ogra_on the SD12:43
apwoh oh where where12:43
ogra_plug it into a PC, copy boot.scr from the first partition, open it with vi, remove the binary junk from the start and save it as boot.script12:43
ogra_then run: sudo mkimage -A arm -O linux -T script -n 'Ubuntu Boot Script' -d boot.script /mnt/boot.scr12:44
ogra_(given your SD was mounted on /mnt)12:44
ogra_oh, and mkimage is in the u-boot-tools package 12:44
ogra_(for all arches available)12:44
ogra_(note the binary stuff only spans half the first line, the rest are proper commands)12:45
ppisatiapw: hdmi is the one close to the usb/eth thing12:46
ogra_right12:46
ogra_with the options i added to the bug i get proper output 12:46
ppisatiapw: copy the text part of boot.scr into a new file (boot.cmd)12:47
ogra_well, usable ooutput 12:47
ppisatiapw: delete quiet and splash12:47
ogra_proper would have been 1080p ;)12:47
ppisatiapw: add console=ttyO2,115200n812:47
ppisatiapw: then execute "mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 10.10" -d ./boot.cmd ./boot.scr"12:47

ogra_its stable if i add video=HDMI-A-1:1280x800@6012:48

ppisatii mean video oiutput12:57

ogra_well, the dvi.debug=7 cmdline option really helped here 13:01
ogra_and picking a mode from the debug output and forcing it on cmdline makes everything work13:02

ogra_i just cant seem to use 1080p13:02
ogra_but i guess the driver defaults to 1080p since the monitor reports it wworking13:02
ogra_so i wonder if its a video ram issue13:02
ogra_but it doesnt seem to matter what i put into vram13:03
ogra_ppisati, hmm, according to the ML you submitted the fix for the logo on june 6th ... why am i still seeing penguins13:12

=== dileks is now known as Guest67607
ogra_ppisati, argh, now i see ... your commit was on the 6th ... the last upload of the omap4 kernel was on the 5th though13:19
ppisatiogra_: yes, we are still using alpha1 kernel13:20
ogra_ah, k13:20
ppisatiogra_: btw wait13:20
ogra_so there cant be a kernel difference between live and preinstalled then13:20
ogra_good13:21
ppisatiogra_: btw, i just booted another image13:21
ppisatiogra_: and it works here (video i mean)13:21
ogra_well, what shall i say, it doesnt here :)13:22
ppisatiogra_: do you have abn installed system?13:22
ogra_yup, but with the video= options added13:22
ogra_*option13:22
apwman these heartbeat leads take some time to start, its all scarey13:25
ogra_apw, yep, fixed in the tree already13:26
ogra_(they are modular and initramfs-tools dont pull them into the initrd, so you only get them once the rootfs is there)13:27
apwogra_, likely we should just build 'em in13:28
apwthe board loooks sooooo dead without 13:28
ogra_yep, paolo already changed that13:28
ogra_just not uploaded yet13:28

ogra_if the hearbeat is up, you should be fine13:30
bjfikepanhc, do you know of more highbank patches coming?13:36
ikepanhcbjf: I do not know that yet.13:38
ikepanhcrobher: any idea? I think you are the best man to answer this13:38
robherbjf, ikepanhc: there's always more coming ;) It should only be fixes at this point.13:41
apwwe probabally errd having it in master13:41
bjfrobher, though true, i was looking for a little more insite into what you know is actually in the pipeline heading our direction in the next 3 weeks13:46

ogra_http://cdimage.ubuntu.com/daily-live/current/ are the new images ... just FYI ... wont change a thing about the kernel issue13:48
apwppisati, indeed the ones i tested, and not working at all for me13:48
* ogra_ grabs his beagleXM and starts an omap test13:49
robherbjf: There's 2 issues I'm working. I've figured out the root cause of "TEMP: force DMA buffers to non-bufferable on highbank", so this can be reverted/dropped. However, doing so breaks reboot cmd. The other issue is that power key driver doesn't really work because without a desktop, nothing in userspace will handle pwr key. On x86 it is handled by acpid...13:50
ppisatiogra_: leave your panda there13:52

ogra_ppisati, fyi, omap works :)13:57

brainsmokeIt makes it easier to write an exploit, given that a program contains a bug13:57
ogra_though the font is all blue13:57
apwsconklin, ^^13:58
brainsmokeyou basically only need one (or if you are lucky no) extra gadget for your return oriented programming exploit13:59

apwogra_, bad the tracker points to preinstalled images for server too14:10
apwfrankly its too hard to help to do any testing on these images14:11
ogra_apw, thats because Daviey is such a slacker14:11
ogra_server stays preinstalled for now :)14:11
ogra_until the x86 server images stzart using squashfs14:12
ogra_ppisati, hmm, so i see the squashfs errors (and hang) every other boot here ... i now have a working installer on the screen, but that required a few reboots14:18

ogra_pgraner, we will get a new code drop from TI that will fix it, not worth to put to much time of paolo into it 14:44
ogra_(there was hope to have that drop before A2 but apparently that failed)14:45
pgranerogra_, when do we expect it to drop?14:45
ogra_ask ppisati :)14:45
* ogasawara back in 2014:45
pgranerogra_, so the arm desktop image is not getting tested for A2?14:48
ogra_it works fine here 14:49
ogra_with either changing the cdmline or booting without monitor plugged in14:49
ogra_beyond that it has no issues at all it seems ...14:50
ppisatiogra_: actually for the next kernel we won't get any code drop from TI, we'll use vanilla + stuff from Linaro as needed15:04
ppisatipgraner: ^15:04
ogra_urgh, scary15:04
ppisatiogra_: there was an email circulating about it on the kernel ml15:04
ppisatiogra_: TI won't support 3.515:05
ogra_well, what are they working on atm ? i thought there was a future kernel planned15:05
ppisatiogra_: they stay on 3.415:05
ogra_beyond the rock solid 3.4 one that ndec's team has15:05
ogra_oh15:05
ogra_well, switching is pretty scary, did linaro actually tell that they will have no regressions wrt what we had in 12.04 ?15:06
apwcking, if those tests are easy to 'run' it might be worth comparing the P kernels too, to see if its broken in Q15:06
ckingapw, it's easy but bloomin' time consuming15:07
ppisatiogra_: no no, we won't use linaro15:07
ppisatiogra_: i'm picking stuff from tilt, not the entire kernel15:07
apwppisati, so we are running a head of ti ?15:07
ogra_apw, ... and will suffer badly ...15:08
ppisatiapw: if we want to have ti-omap4 on 3.515:08
ppisatiapw: else it'll be another topic branch with a different kernel15:08
pgranerppisati, can you or someone from the kernel team drop a bug number for the video issue in ubuntu-release and give skaet an eta on the fix pls. 15:08

* ppisati has started today to assemble it...15:15
ogra_without it we wont have the devices in pulses gui15:15
ogra_but there is enough time before release to fix that i suppose15:16
skaetogra_, actually not...   Based on the time it took yesterday,  I think we're out of runway for A2.   Getting it fixed and in the next set of dailies should be done.15:18
ogra_skaet, if i say release i mean release ;)15:18
ogra_not milestone ;)15:18
ogra_the images we have atm look fine for A2, no need for respins or changes15:19
skaetogra_  the workarounds are pretty ugly.15:20
ogra_skaet, boot with no monitor attached until the LEDs blink wildly ? 15:21
ogra_(or you are sure that X is up)15:21
ogra_i dont think thats to hard as a workaround15:21
ckingarges, some rough notes on their way to you + a hacked version of jack_delay15:24
keesapw: please don't backport 2e57ae0515124af45dd889bfbd4840fd40fcc07d -- it doesn't play well with seccomp.15:31
keesapw: if anything, vsyscall should be "none" -- it's entirely deprecated.15:32
skaetogra_, can you please add how this image needs to be worked around to the TechnicalOverview right now,  and given where the issue is happening,  we should probably add this to the notes on the top of the ISO tracker by these images at least.15:34
ogra_skaet, will do, its noted in the bug along with another way that worked for me 15:35
bjfkees, huh, can you comment on the bug? i was already working on it.15:35
skaetogra_,  yeah, but getting people to know about the bug an read it, as well as instructions for how they should interoperate with these new style images is going to be needed.15:36
apwbjf, i've referred that whole thing to security15:36
bjfapw, ack15:36
ogra_skaet, indeed, though i expect the users to show up in #ubuntu-arm if they cant get along anyway :)15:36
skaetyeah,  but give them some clues and pointing them there, is only polite ;)15:37
apwogra_, for you if you plug hdmi in at the point when the flashies start and you are good ?15:37
ogra_apw, right 15:38
apwdefinatly does not work at all for me15:38
ogra_i use an HDMI->DVI cable ... with the HDMI side attached to the HDMI port of the panda15:38
apwsame as here15:38
ogra_hmm, it cant really fail since booting without monitor forces it into a hardcoded mode 15:39
apwogra_, and what is the mode15:39
ogra_unless your monitor cant do the 800x600 or 1024x786 or whatever that default is15:39
apwis a 1080p monitor, so it can emulate both of those, it did to my main box when i was fiddling just recently15:40
ogra_apw, i have to boot into a broken setup again to find out, currently my beagle has all the stuff plugged in, will test the mode later15:40
apwdiwic, ok that patch does have an = in the if so the report is valid, the form you have however is likely also valid so feel free to ignoew ir15:55
ogra_RAAAH !15:57
* ogra_ goes mad ... who decided to add that silly microSD slot on the beagle at a place where i alwas accidentially rip it out of the slot15:58
* ogra_ starts the same install for the third time 15:58
diwicapw, aha, it does, I just didn't see it because it complained on another line than the actual =16:12
apwyeah you can ignore it, that construct is getting no simpler thats for sure16:15
ogra_ppisati, so my omap install failed again and it looks to me like there are USB issues, i get lots of dropped event messages from the NIC driver and the copying of the OS to USB key fails at some point (sadly without any error)16:16
ogra_oho !16:17
ogra_ubiquity: page allocation failure16:17
ogra_there we go16:17
apwadd more swap16:19

ppisatiogra_: who said i'm not going to watch the match? :)16:34
ogra_heh16:34
* ogra_ cant work if its an exciting one :)16:34
ppisatiwell, spain vs portugal, who knows16:34
ppisatiportugall will be covered for 90m + 30m 16:35
ogra_i guess spain will do it 16:38
ogra_tomorrow is more exciting though :)16:38
ogra_germany never managed to beat italy ... 16:38
ppisatiogra_: you will16:45
ppisatiogra_: first because your team is better this year16:45
ogra_well, i fear our players are scared by the fact 16:45
ppisatireally?16:45
ogra_and might make mistakes due to it16:45
ogra_but yeah, they are better, but its football, its not always the better team that wins16:46
ppisaticonsider that Italy had just 3 days to recover from the previous match + prepare the new one16:46
ppisatiright16:46
ogra_and your guys still have an awesome talent to confuse the other team 16:46
ogra_so catching a goal or two is very likely for germany.... the question is how they handle that 16:47
ppisatino no16:47
ppisatiless rest16:47
ppisatiless time to prepare16:47
ppisatia couiple of key players out (De Rossi and Chiellini)16:47
ppisatiit'll be a suffering tomorrow16:47
ogra_i doubt that, i think it will be an exciting game with well balanced out results 16:48
ppisatiwell, we will see16:48
ogra_i would be less worried to see them play against spain than against italy16:49
ppisatibut i would be *really* surprised if Italy can make it16:49
ppisatireally?16:49
ogra_well, they made it this far 16:49
ppisatiyou must be kidding16:49
ppisatii mean16:49

ppisatiuh?16:49
ppisatiare we watching the same stuff?!?!? :)16:49

ogra_they didnt deserve a single win they had this EURO16:50
ppisatiwell16:50
ogra_they do their show etc but dont manage to shoot goals 16:50

ppisatiogra_: it was one of the "best" match i've ever seen16:52
ppisatiogra_: well balanced16:52
ogra_++16:52
ppisatiogra_: and with a good ending :)16:52
ogra_haha16:52
ppisatiogra_: don't worry, you'll get your revenge this time16:52
ogra_we'll see, i will belive it tomorrow night 16:53
ogra_would be fun if portugal kicked out spain though 16:53
ppisatii've a frind who bets against Italy16:53
ppisatiso16:53
ppisatiif Italy passes, he's kind of happy16:53
ogra_heh16:53
ppisatiif it looses, he's still happy! :)16:53
ppisatiit's a win-win condition16:54
ogra_i heard about betting on germany from several people 16:54
ogra_anyway, i need some food and then need to write some notes for kate before the game 16:55
