htorquehi everyone! don't know if that's the right place to ask, but my new ssd is not used as sata-iii drive and i'm stuck with sata-ii speeds.12:38
htorquehere's a snippet from dmesg: http://paste.ubuntu.com/679685/ (crucial m4 connected to ata1 on an intel z68 based board)12:38

smoserbjf is there a a way i can appease your bot at bug 838199 ?13:31
ubot2`Launchpad bug 838199 in linux "initramfs blkid /dev/xvda1 did not return, failed boot" [Undecided,Confirmed] https://launchpad.net/bugs/83819913:31
ogasawarasmoser: I just posted a comment there13:31
bjfsmoser, just change the status to "confirmed" and it will leave the bug alone13:32
bjfsmoser, you just tease it when you put it back to "new", note this is actually explained in the comment that is added13:33
_-maksis there a linux version known that you'll pick for 11.04?13:43
_-maksdebian is freezing in june so we might be able to sync13:43
_-maks3.4 looks optimistic but maybe feasible?13:44
_-maks3.2 for christmas, so easter with 3.313:44
_-maksso maybe to optimistic13:44
bjf_-maks, did you mean 12.04 ?13:45
ogasawara_-maks: as bjf mentioned, I assume you mean 12.04.  I don't think any of us have actually yet looked to see where upstream would be at for our 12.04 release, which happens to also be an LTS (long term support) release.13:48
ogasawara_-maks: being an LTS release, we'd likely err on the side of being conservative13:49
ogasawara_-maks: and it would be nice to be in sync with other distros13:49
ogasawara_-maks: if 3.3 looks to be releasing around easter, I suspect that is what's we'd try to target13:50
tgardnerogasawara, that might be a bit aggressive for an LTS13:51
bjfogasawara, tgardner since gregkh is talking about picking a kernel to support for two years, i assume we'll pick his brain next week13:52
smoserthank you ogasawara bjf . i will try to learn to read.13:52
ogasawaratgardner: indeed would be nice to know what the next long term kernel will be13:53
bjfogasawara, tgardner in case you hadn't seen this already: https://plus.google.com/111049168280159033135/posts/VyWdYvHnAS213:55
tgardnerogasawara, if it was just x86 we had to worry about I'd choose 3.2, but I'm sure Linaro will have some influence.13:55
ogasawarabjf: yep, read in on LKML and tgardner replied13:57
bjfogasawara, if it's not on G+ i don't see it :-)13:57
ogasawarahehe13:57
ogasawara_-maks: so I think what we're saying is we have no idea yet :)13:58
ogasawara_-maks: but I can be sure to interlock with you when we do decide.  we should have a better idea around UDS (early Nov).13:59
bjf_-maks, if you were going to be at plumbers next week we could discuss it there14:03
hertonsmb: are you going to rebase ec2 against lucid respin (bug 837804), or that isn't needed? I'm asking because if it will not be rebased I'll mark verification done for the previous ec2 update so it can go to testing14:17
ubot2`Launchpad bug 837804 in linux-ec2 "linux-ec2: <version to be filled> -proposed tracker" [Medium,In progress] https://launchpad.net/bugs/83780414:17
smbherton, I am right now in the process of doing it as the two newer reverts may have a chance to have impact14:18

hertonppisati: I was checking you lucid/mvl-dove branch, the tag Ubuntu-2.6.32-218.36 isn't pointing to the top of your tree (I was expecting it pointing to commit 2dcf1e845f2b8986e50510acaf13ca0b24a96497)14:20
ppisatiherton: strange14:22

ppisatiherton: what about now?14:29
hertonppisati: looks ok now14:32
htorquemeh, so my sata-iii ports work at sata-iii speed depending on having disks attached to sata-ii ports or not - is this a bios/efi problem or something kernel-ish to report?14:53
Tommehhtorque: you might need to explain that a bit better.14:58
TommehI don't fully understand what scenario you're referring to -- it could be one that's expected or not.14:58
htorqueok, sorry. i attached a sata-iii ssd to a sata-iii port on a intel z68 based motherboard but speeds were capped at sata-ii speed (tested using palimpsest). i then removed my also attached sata-ii hdd from its sata-ii port and now i'm getting full speed from the ssd.15:02

cndsforshee, I was trying to respond to your email, but it seemed easier to chat about it17:18
cndare you around?17:18
* tgardner --> lunch17:48
cndsforshee, I got tired of waiting, so I typed it all out :)17:52
sforsheecnd, I'm back, just read your email18:05
cndk18:05
cndI'm happy to chat if you have any thoughts18:06
sforsheefirst off, Dmitry said in the elantech patch review that MT coordinates should be scaled up to the same scale as single-touch coordinates18:06
sforsheeas far as the points being different, it could be bigger than you're assuming18:06
sforsheeI'm reporting (min_x, min_y) and (max_x, max_y) pairs18:06
cndsforshee, yeah, I saw those comments from dmitry, but I didn't look too closely18:06
sforsheewhereas the fingers could actually be at opposite corners18:07
sforsheeopposite from what we're reporting, that is18:07
cndoh, that's fine18:07
cndthat's what SEMI_MT is all about :)18:07
sforsheeand if there are more than 2 fingers, I have no idea what the single-touch coordinate the device is reporting corresponds to18:07
sforsheecould be something in the middle18:07
cndsforshee, the point is that the bounding box should be accurate18:08
cndas long as that is accurate, it doesn't matter where the touches are physically18:08
cndthat's the best we can do18:08
sforsheeand the ABS_[XY] pair doesn't have to correspond to one of the corners of the bounding box, correct?18:09
cndnope, it should just be inside the bounding box18:09
cndwhich may be another reason why the mt axes should have less range18:10
sforsheeokay, we should be good there then18:10
cndotherwise, if you scale up your ST coords may not live exactly inside the box18:10
cndthey could be a few units outside18:10
sforsheehmm, I guess so, but that's still counter to what Dmitry said18:10
cndyeah, I'm going to find the patches and bring it up on the thread18:11
sforsheeit was on probably the first version of the patches from elantech, they're on something like v4 now18:11
sforsheecnd, https://lkml.org/lkml/2011/8/18/6918:12
sforsheebut for their patches it won't matter because the ABS_[XY] is always also one of the MT points18:13
cndsforshee, you've read the elantech patches more than I, so I'll ask you some questions18:14
sforsheeok, shoot18:14
cnddoes the elantech have the same resolution for MT and ST data?18:14
cndwas dmitry's issue just that it could concievably be different?18:14
cndor is it like the alps stuff18:14
sforsheeactually I'll have to look, I just remembered that this is wrt the v2 protocol which I'm not familiar with :)18:15
cndsforshee, do you mind if I mention your work with the alps trackpad?18:15
sforsheeno, I've already mentioned I'm looking into it on a bugzilla18:15
cndok18:16
sforsheecnd, it does look like in elantech v2 protocol the MT points are lower resolution than ST18:17
sforshee(brb)18:18
cndok18:19
sforsheecnd, but what I said before holds -- the ST point is the same as one of the MT points18:20
sforsheeit will never fall outside the bounding box18:20
cndok18:26
ExodusHello18:42
ExodusHow does one inquery a kernel bug here?18:45
=== nickde is now known as Guest38625
ExodusThere's this bug with AHCI being loaded as a module that makes some hardware freeze for 10-25sec on startup18:45
ExodusIf it's compiled into the kernel it doesn't present this issue18:47
ogasawaraExodus: might help if you mention the actual bug # and which kernel version?18:57
ExodusWas actually hoping someone would say anything so I don't rant by myself here19:00

ExodusThat second one is a duplicate19:00
ExodusBut further down that second one there are very useful comments19:01
ExodusAnd tests19:01
ExodusBug persists over various distributions19:01
Exodusand Ubuntu releases19:01
ExodusI think, compiling AHCI into the kernel instead of loading it as a module will fix the issue19:02
ogasawaraExodus: considering the second bug has been marked a duplicate of the first and the first is marked Won't Fix I suspect no one is looking at it19:14
ogasawaraExodus: it's best if you probably file a new bug and confirm it's still an issue with the latest Oneiric beta release that'll come out today19:15
ExodusWill do19:17
ExodusCan't someone just reopen the bug?19:18
ExodusI could just remove the duplicate from the later bug19:18
ExodusThere is a lot of info on those comments19:18
ExodusAnd feedback19:18
ExodusWould be a waste to create a new bug19:18
ExodusIs creating a new bug the proper way to go?19:18
ogasawaraExodus: I'd just reference the older bugs in the newer one, or pick out the relevant bits of info and add to the new bug.  the older bugs seem to have some random comments you have to sift through which is annoying sometimes.19:21
ExodusTrue, I'll make a new bug then. Thanks.19:22
