sn92.6.15-13 segfaults on boot. anybody interested in details?01:33
cjbI'm not one of the developers, but I haven't heard of a bug like that; I think you should file a bug report.  Did previous kernels work?01:35
sn9it's mostly a breezy system with a few packages from dapper. 2.6.15-9 worked considerably better than the breezy kernel01:36
=== garbage_ [n=garbage@bgepxyout-02.asiapac.hp.net] has joined #ubuntu-kernel
sn9someone evidently borked the keywest i2c driver after that01:38
sn9that's what segfaults01:38
cjb.. or it's your mix or kernel/userland.01:38
cjbs/or/of/01:39
sn9i have the dapper udev01:39
=== mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-kernel
sn9the system still boots like nothing's wrong, but things that rely on i2c are borked, like alsa01:41
sn9dmesg is what revealed the segfault01:42

psusifabbione, ahh, you're back from vacation I see?  enjoyed it I hope?  before you left you asked why I reassigned the dmraid bug to you instead of adam conrad?  he said he had no idea why it was assigned to him and that I should switch it to you04:05
fabbionepsusi: ok, in anycase since the package is in universe you can just ask MOTU to look/upload it04:09
fabbionethere is no need of me doing it04:09
psusiok....  right now i'm working on properly udebifying it and integrating it into partman... 04:09
fabbionei am really of no use for it as it is04:10
fabbionei still didn't get to look at the kernel problem i am having04:10
psusikernel problem eh?04:10
fabbione= my system doesn't see the disks04:10
psusiyou aren't using both sata and pata are you?04:11
fabbionei only have pata04:11
psusiit seems current kernels don't like mixing the two04:11
psusiohh04:11
fabbionenothing like that04:11
fabbionethe controller module is loaded04:11
psusiwow, so it just doesn't see the disks at all eh?04:11
fabbionebut it sees no disks04:11
psusiwhich controller is this?04:11
psusipromise?04:11
fabbione0000:00:08.0 RAID bus controller: Promise Technology, Inc. PDC20378 (FastTrak 378/SATA 378) (rev 02)04:12
psusiI believe the via module has to program the controller to run in non raid mode for the disks to show up normally, then it hands off to libata... maybe the promise module doesn't do that part?04:12
psusido the disks show up if you tell the bios to use non raid mode?04:12
psusiok... so that is the controller that supports both pata and sata... but you only have pata drives plugged in?04:13
fabbionei didn't check anything yet04:13
fabbione-ENOTIME04:13
fabbioneand -ELOWINTEREST04:13
psusiI've seen a lot of problem reports about that controller and pata in recent kernels, but I had thought it was from trying to use both at once04:13
psusihehe04:13
psusiearlier on in the bug history, you mentioned that it should eventually be assigned to installer-integration I think it was?   is it time for that now?04:15
fabbionepsusi: not without udeb and main inclusion report04:16
fabbioneyou will need to test it first04:16
fabbione+ you are doing the installer integration04:16
fabbionenobody knows better than you what you are doing04:17
psusiok.... I'll keep working on that then.... I think the udeb is ready... just need to modify partman to use it correctly from the setup cd.... espresso install from livecd should be easy though once that's working04:17
psusiI guess I should start working on a main inclusion report then too eh?04:17
fabbionepsusi: the main inclusion report is a wiki page.. get teh code for partman working first04:18
psusiok....04:18
psusiyea, I've seen the page04:18

dilingerdapper + cryptdisks (dm-crypt) + 3ware + raid5 (swraid) + 700gb data is giving me such headaches :/05:16
dilingergetting random unreproducible read errors05:17
psusipoke at it with smartctl?05:18
dilingeryea, already did05:18
dilingerno smart errors, lm-sensors think everything is fine05:18
psusiwas getting some odd access denied errors in my daily backups on a server at work the last few days... had smartctl make it do it's long internal test... had a few completely unreadable sectors, and a TON of recoverable errors...05:19
fabbionedilinger: meh dude....05:19
dilingerpsusi: also, rechecking is valid05:20
dilingerpsusi: ie, flac -t foo.flac will fail the first time, succeed the second time05:20
psusiohh, that's nice05:20
psusianything interesting in dmesg?05:20
dilingerbut it's about 3 flac files out of about 700GB05:20
dilingernope05:20
dilingerkernel doesn't see any errors at all05:20
dilingeri've only done smart short tests, though05:21
psusimy via controller gets timeouts after I resume from suspend... it seems it needs longer than the kernel is willing to wait to wake back up05:21
dilingeri guess i can schedule some long tests05:21
psusiincreased the timeout duration fixed it05:21
psusido the long one, yea... short doesn't seem to do much05:21
dilingerthis would be a lot easier if i could reproduce it easier.. as it stands, it takes about 2 days to run the full test05:21
psusialso look at smartctl -A... see if it reports a number of recoverable errors05:22
psusiwhy does it take 2 days?05:22
psusitakes me ~30 mins on my 10,000 rpm drives here... took ~85 mins on the big 7200 rpm drives on the server at work05:22
dilinger'cause it's 700gb of data :)05:22
psusispread on multiple drives05:22
psusiall the drives can be doing their tests at once ;)05:23

oceandeadI'm sorry if I'm in the wrong place but I wasn't sure where to go with this (I didn't want to send email to a list - fearing this topic has already been brought up). Also, I haven't been able to participate in laptop-testing since Breezy Colony3 (will again be testing soon), so I'm also not sure if it's already been included or not. 08:40
=== garbage_ [n=garbage@bgepxyout-02.asiapac.hp.net] has joined #ubuntu-kernel
oceandeadAnyway, I was wondering what the status of inclusion of rtl8180-sa2400 wifi chipset drivers might be.08:40
oceandeadI checked all the mailing list archives I could find but saw nothing about it. Anyway, the sourceforge page can be found here - http://rtl8180-sa2400.sourceforge.net - They (rtl8180-0.21) compiled fine for me under Hoary. I had problems compiling the CVS version under Breezy but luckily a user who successfully compiled them created a .deb package of the compiled drivers for i386. 08:44
fabbioneoceandead: if it is not in dapper, open a bug in malone08:47
oceandeadfabbione,  will do 08:47
oceandeadthanks 08:47
oceandeadand thank you all for all of your hard work 08:47
