NCommanderapw, can you please comment on https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/280669; I tested your DMA patch for the jax10 with bonnie++, but I don't seem to get any better performance15:36
ubot3Malone bug 280669 in linux "DMA mode and driver jax10" [Low,Triaged] 15:36
apwNCommander, so if its not of benefit we don't need it then?15:37
NCommanderapw, that was my conclusion since bonnie++ only shoed a minor change (likely noise)15:38
smb_tp_apw, As we were asked today about the hibernate prevention. I could propose a change that inhibits hibernation if that file is present. There would be two questions, though15:47
smb_tp_a) It doesn't seem that file is automatically removed on reboot15:47
apwsmb_tp_, yeah looking at it right now as it happens15:47
smb_tp_b) Is there a way to be more obvious than just not doing anything 15:48
apwthere is lots of places which know how to do it.  in theory desktop stuff should can implement it15:48
apwi have been playing with using notify to show the inhibit as well15:48
apwlet me play for a bit15:48
smb_tp_My approach was a hook in /usr/lib/pm-utils/sleep.d which call inhibit on fail15:48
apwyeah.  thats what i have been doing as the 'last fallback' was looking to see what we could do higher up too15:49
apw/var/run gets wiped on reboot does it not?15:49
smb_tp_Thinks...15:49
smb_tp_Oh could be. Gosh, I always hibernated when things did not work correctly, so the file is there naturally.15:50
smb_tp_forget a) then15:50
apwright ... stilll looking at gnome-power-manager to see if tis easy to tell it too15:50
apwit hink there is an official interface for desktop in general15:51
apwbut ... step one is to do it in pm utils so it works for everything15:51
smb_tp_That would be a good thing15:51
apwso ... i am working on it15:51
smb_tp_Ok, then I leave it to you. I thought I might help as you actually should sleep, get breakfast and other stuff...15:52
apwsmb_tp_, who needs sleep15:53
smb_tp_I usually do15:53
apw:)15:53
=== JayFo is now known as JFo
manjosmb_tp_, one of the changes I made fixed the resume issue... but now I dont know which one :)17:32
smb_tp_manjo, Well, proper solution there would be to take out one change after the other and retest. ;-)17:33
manjo:) heh that is what I am doing ... stupid me.. was working from the same tree all along 17:34
smb_tp_On the good side the number of changes you did is likely not too vast17:35
manjono like 3 changes17:35
jbarnesmanjo: fyi there's a patch available for the java crash17:48
manjojbarnes, cool! 17:48
manjodo u have a ppa that I can test ? 17:48
jbarnesit really works around the core issue (server bug) but it works for me17:48
jbarnesmanjo: bryce provided one... lemme get the url17:49
manjook17:49
jbarnesoh he didn't give a url, just said it was in his personal ppa17:49
manjolet me ping him 17:50
manjojbarnes, no responds from bryce ... 18:01
jbarnesdoesn't launchpad give you access to his ppa?18:02
manjolooking .. 18:02
manjoall I see is a change in status from Triaged to In Progress... 18:04
manjowaiting  for bryce to respond .. will let you know what I find .. 18:05
jbarnesok18:09
bradfmanjo: ping18:15
manjopong18:15
bradfmanjo, i'm adding a driver config (mvsas)18:16
bradfmanjo, in the modules files in d-i what is the significance of the ? in the files?18:16
manjowhich file is that ? 18:17
bradfmanjo, d-i/modules/scsi-modules18:17
bradfmanjo, if you look at d-i/modules/fb-modules the lines don't have a ? after the driver18:18
=== k-s[AWAY] is now known as k-s
manjobradf, dont know what that means... some have ? others dont ... 18:25
bradfmanjo: yup, that's why I was asking18:26
manjobradf, something to do with python parser ? 18:26
bradfmajo, how do those files get used?18:27
manjoI think the debian-installer does some magic 18:28
manjoI think it generates a dsc file from that list 18:28
IntuitiveNipplethey're used in debian/rules (around line 98) to exclude modules on a per-arch basis - the names can have shell glob expansions18:28
manjoIntuitiveNipple, so ? is unwanted ? 18:30
manjocoz I dont see any regex for looking for  ? 18:30
IntuitiveNipplemanjo: not sure on that; but that is how it is used (the final expansion is done with the "xargs rm -f")18:31
manjohmm pure magic 18:32
manjobradf, ? disables the module18:59
manjobradf, debian kernel wedge does some magic to take that out 18:59
manjomvsas in debian is under scsi-extra-modules18:59
manjobradf, so adding mvsas without ? enables it for d-i19:00
manjobradf, gen-control does some magic 19:01
bradfmanjo, thanks19:02
bradfmanjo, might have pulled the trigger a little soon on my patch, sigh19:03
manjoheh u did not tst it !19:04
manjohttp://kmuto.jp/svn/d-i/etch/d-i/packages/kernel/kernel-wedge/commands/19:04
bradfmanjo, built it, don't have the hardware that matches the module19:05
manjoah someone will report that it does not or does work ... u can fix then I guess19:05
manjobradf, I posted the link with the commands that looks at those files ... you can look at the perl scripts and guess if that is exatcly what It dos 19:06
bradfmanjo, thanks, am looking at it now19:07
manjodebian builds are just magic... I am glad I dont have to mess with it 19:07
* manjo goes back to regular scheduled program of debugging 19:08
bradfmanjo, according to rtg: A '?' implies the module is optional, e.g., if it doesn't exist for a19:16
bradfparticular config then its not an error.19:16

RainCTHi22:14
RainCTSince a few weeks my filesystem is corrupting all the time. I'm on Jaunty (this first happened with ext3 so I thought it was a problem with it but from then on I've reinstalled Jaunty several times choosing ext2 and it still happens). Any idea?22:17
RainCT(all the time = usually once a day or more often. I'll power off and when I start the PC again it'll run a fsck because of not being umounted properly and find lots of errors which it asks me to repair manually, or sometimes even grub will directly refuse to boot and I'll have to fsck from a live CD. Sometimes it even corrupts while I'm using it and / switches to read-only, and after a while fails completely and gives "read errors", also getting fixe22:21
RainCTMay this be because of the kernel or is it a hardware fault (which I doubt as the hard disk isn't even 5 months old)?22:22
dtchenare updates involved at any step?22:27
RainCTdtchen: Afaics no, but the lowest I've tried is plain Jaunty Alpha 5.22:28
dtchenalso, is this "plain ext3", or is it "ext3 on LVM", "ext3 on encrypted LVM", etc.?22:28
RainCTplain ext322:29
RainCT(err above in my first sentence ext3=ext4, ext2=ext3)22:29
dtcheninteresting. i cannot reproduce the symptom across fresh boots, but i can across week-long suspend-to-ram/resume cycles.22:30
dtchenit's reproducible for me on plain ext3, ext3 on LVM, and ext3 on encrypted LVM22:30
dtchen(however, i'm also using wl and nvidia, so who the heck knows?)22:30
RainCTI'm downloading Lenny now, will see if it fails there too. (I've decided this is a signal for my to finally try out Debian :P).22:31
dtcheni don't think it's Ubuntu's kernel, per se. i remember the first time i had a trashed jaunty install was while running the kernel-ppa mainline build of 2.6.29-rc5.22:32
pwnguinRainCT: when you say the FS is corrupting22:33
pwnguinarg22:33
pwnguindata loss, or fsck triggers?22:33
RainCT(sorry, damn Ethernet cable :P)22:33
pwnguinRainCT: when you say FS is corrupting, do you mean data loss, or fsck triggers?22:33
RainCTpwnguin: both, although usually the data loss is not serious22:34
pwnguinand you power off normally?22:35
RainCTYes22:35
RainCTFor some time there was some message before it powered off (if I booted without "quiet splash")22:35
RainCT"could not iterate IDE devices" or something like that (I'm telling from memory from several days ago)22:36
pwnguinis there any raid involved?22:36
RainCTnope22:36
pwnguinhow old is the drive and whatever it plugs into?22:37
RainCTIt's a laptop, less than 5 months old, partitions: sda1 (ext3, /) and in an extended partition sda6 (ext3, /home) and sda5 (swap); both sda1 and sda6 have the problem22:38
RainCT(I've reinstalled and recreated the partitions several times, btw)22:38
RainCT(that's the exact error it gave: «unable to iterate IDE devices: no such files or directory»)22:39
pwnguinby chance, do you have diagnostic cds or partitions?22:40
IntuitiveNippleRainCT: Has the laptop taken any unexpected knocks around the time this started?22:40
RainCT(ah, gparted says the hard disk is an ATA TOSHIBA MK2552GS)22:40
IntuitiveNippleIf it were a desktop I'd immediately say "check the cables" - as a laptop I'd say, have you opened the HD access panel and checked the SATA connection and drive are secure22:41
RainCTand no, I haven't moved it much this last months22:41
RainCTand no, I haven't opened it, and I can't (or warranty voids)22:42
IntuitiveNippleit sounds hardware related, so I'd be suspecting something loose or out of place or shorting or overheating22:42
pwnguinhave you searched LP for your laptop model?22:42
pwnguinit sounds like a hardware thing, and if your model is susceptible, that might be an avenue to pursue22:43
RainCTa google search with the model + launchpad only shows webcam support related stuff22:44
pwnguinyou might also check smart for anything22:44
RainCTsmart says "passed", if there's anything else I can ask smart to do I'd need to know the command for that22:45
RainCT(smartctl, that is)22:46
dtchenhmm, yeah, too late for HDA enablements fixes for HP Minis22:50
dtcheni'll queue these for -proposed22:50
