[00:16] <lukehasnoname> Has anyone read "Understanding the Linux Kernel, 3e"?
[02:40] <lukehasnoname> 144 minuts without response
[02:40] <lukehasnoname> *minutes
[02:40] <soren> I have.
[02:40] <soren> WEll, most of it.
[02:41] <lukehasnoname> useful?
[02:41] <soren> Erm... that's a lie actually. Glancing that the index, I've probably read about half.
[02:41] <soren> Very.
[02:41] <soren> I highly recommend it.
[02:41] <lukehasnoname> *goes to amazon*
[02:42] <lukehasnoname> I'm in a "intro to data communications" class; the students all have to install Ubuntu to a live CD. I had to explain to the teacher why there's a "duck" (heron) on the desktop. OH, and she's running FC6 for a server o_o
[03:06] <pwnguin> heh
[03:06] <pwnguin> my uni LUG had an email asking for help with FC1

[08:12] <shenki> 2.6.27-1-generic is rebooting upon resume for me :(
[08:13] <shenki> i was running an upstream .27-rc4, 1941246dd98089dd637f44d3bd4f6cc1c61aa9e4, and it resumes fine
[08:13] <shenki> amd64, thinkpad x300
[08:13] <shenki> any suggestions for how to collect logs would be welcome
[11:06] <gaspa> ﻿﻿hi, hardy-updates has ﻿virtualbox-ose-modules-2.6.24-20-generic, but not the associated kernel. is that only a glitch?
[11:30] <abogani> gaspa: VirtualBox maintainer error, i suppose.
[11:30] <abogani> I think that he'll fix it soon with .21
[11:31] <gaspa> abogani: i meant : there's no project to put in -updates linux-image 2.6.24-20...
[11:31] <gaspa> if so, the solution is: just wait.
[11:35] <abogani> No .20 is supersede. We are just bumped to .22 into Hardy git archive... in any case wait seems the best option :-)
[11:37] <gaspa> abogani: ok, but -updates repositories are broken.
[14:16] <siretart> could someone please triage bug #261590? i feel that it is rather critical, but don't want to triage my own bugs
[14:24] <pwnguin> siretart: you could try #ubuntu-laptop and their mailing list, but it's basically fallen apart
[14:25] <pwnguin> (there might be a thinkpad channel)
[14:26] <mjg59> siretart: Thinkpads don't export fans via acpi
[14:26] <mjg59> It's notabug
[14:27] <mjg59> There's a thermal issue on Thinkpads that's been fixed upstream
[14:27] <pwnguin> alternatively, just spam keywords till mjg notices
[14:30] <siretart> mjg59: err, did this change from hardy?
[14:31] <mjg59> siretart: No
[14:31] <siretart> mjg59: what is today's way of controlling fans on thinkpads?
[14:31] <mjg59> thinkpad-acpi will do it if you ask to it really hard
[14:32] <siretart> so no way of controlling it somehow interactively?
[14:33] <mjg59> Only using thinkpad-acpi
[14:33] <siretart> I thought of echo'ing stuff to /proc 
[14:34] <siretart> mjg59: with 'asking it really hard' do you mean the option 'fan_control=1'?
[14:41] <mjg59> siretart: Yeah
[14:42] <shenki> siretart: the fun happens in /proc/acpi/ibm
[14:42] <shenki> siretart: https://launchpad.net/tp-fan is handy too
[14:43] <mjg59> Bear in mind that the X60 handles high temperatures by slowing down the CPU in firmware
[14:43] <mjg59> That's what was broken at various points
[14:44] <shenki> mjg59: do you know what this message is about:
[14:44] <shenki> "thinkpad_acpi: setting the hotkey mask to 0x00ffffff is likely not the best way to go about it"
[14:45] <mjg59> Yes, with recent thinkpad_acpis userspace shouldn't be setting hotkey_mask
[14:48] <shenki> mjg59: where could that be getting set?
[14:50] <mjg59> /etc/modprobe.d somewhere?
[14:59] <siretart> mjg59: thanks for the information! I'll update the bug
[14:59] <_MMA_> ﻿Does this deserve a bug report? http://mma.users.ubuntustudio.org/vbox.png It's using the latest on-disk image -generic kernel.
[15:00] <siretart> shenki: that would be bug LP #256887
[15:02] <shenki> siretart: thanks,i just found it myself too
[15:02] <shenki> stgraber: heh, we added the same comment. you bet me by 49 seconds.
[15:02] <siretart> :)
[15:05] <tjaalton> shenki: it's hotkey-setup, I'll fix it
[15:05] <mjg59> Remember that just removing the file from the package won't fix it, since it's a conffile
[15:05] <siretart> shenki: TBH, I'm a bit hesitant to add a /etc/modprobe.d/thinkpad_acpi.modprobe. what happens if 2 files define options for the same module?
[15:06] <shenki> siretart: mmm, hotkey setup would run after the modprobe, so it would over write modprobe's settings
[15:06] <tjaalton> mjg59: it's echo'ed during init, so just removing that part should do, right?
[15:07] <mjg59> Yeah
[15:07] <mjg59> Oh, of course, it's part of the init script
[15:07] <tjaalton> yep
[15:08] <shenki> the docs suggest setting it to /sys/devices/platform/thinkpad_acpi/hotkey_recommended_mask
[15:08] <siretart> cat /sys/devices/platform/thinkpad_acpi/hotkey_recommended_mask > /sys/devices/platform/thinkpad_acpi/hotkey_mask
[15:09] <shenki> indeed.
[15:09] <siretart> but that's something the module could it itself. if it doesn't do that already
[15:10] <shenki> later on, it talks about not messing with defaults for the backlight control when one has acpi video
[15:10] <shenki> "For Lenovo models *with* ACPI backlight control"
[15:12] <shenki> siretart: have you attempted resuming from suspend with .27?
[15:12] <siretart> shenki: suspend works on my X60s, I haven't tried hibernate yet, though.
[15:12] <siretart> resume btw as well
[15:13] <tjaalton> I wonder if that breaks my screen not resuming from powersave-mode
[15:13] <tjaalton> with .24 it's ok
[15:13] <shenki> my x300 was rebooting (instead of resuming) with .27-1-generic, but resumes fine with upstream ~rc4
[15:14] <mjg59> shenki: Known bug in ftrace
[15:14] <shenki> mjg59: thanks
[15:17] <shenki> ah, and there's the fix. ftrace: disable tracing for hibernation. cool
[15:21] <mjg59> There's another one for suspend to ram
[15:22] <shenki> noticed that. figured i was talking to myself enough. don't need to correct myself too
[15:39] <tjaalton> siretart: I'v tried commenting out that stuff from the initscript, and now hotkey_mask is the same as hotkey_recommended_mask
[15:40] <tjaalton> ok, so my laptop screen really doesn't want to resume frome the powersaving mode
[15:40] <tjaalton> intel
[15:40] <tjaalton> need to reboot to get it back
[15:41] <siretart> tjaalton: so let's claim that setting the hotkey mask was an quirk that is not necessary anymore with current thinkpad_acpi, and we should remove it completely from hotkey-setup
[15:41] <tjaalton> siretart: indeed
[15:43] <siretart> tjaalton: does your ThinkVantage button do something useful? It doesn't for me since (and including) hardy
[15:43] <tjaalton> nope
[18:08] <cjwatson> 2.6.27 seems to have cleared up the intermittent usplash misrenderings for me
[18:17] <BenC> cjwatson: ogasawara said the bug showed others claiming the same
[18:26] <cjwatson> wl driver seems to work, though curiously b43 is still loaded
[18:34] <BenC> cjwatson: does jockey do anything to divert conflicting open/closed drivers?
[18:39] <cjwatson> no idea
[18:39] <cjwatson> wl is still closed from its point of view anyway
[18:39] <cjwatson> it's in linux-restricted-modules and listed in the jockey UI
[18:47] <BenC> cjwatson: I notice alsa-utils 1.0.17 was uploaded
[18:47] <BenC> that was fast
[18:48] <cjwatson> yeah, Luke squeezed it in under the freeze last night
[18:48] <cjwatson> sound still works for me at any rate
[18:49] <BenC> freeze?
[19:22] <CarlFK> .27 - ﻿I now ﻿have both ath5k and ath_pci loaded at the same time, which I think is bad - should I file a bug in lp?
[19:26] <BenC> CarlFK: Disable ath_pci by either uninstalling linux-restricted-modules or using "Hardware Drivers" control panel
[19:28]  * BenC => reboot
[21:57] <CarlFK> is there some way to redirect kernel boot output to usb?  (laptop has no serial ports) 
[22:03] <CarlFK> booting .27 - it pauses at various places, like right now at "[3.11...] SCSI subsystem initialized" - been there for over 1 min.  If I hit any key (spacebar) it will continue, then pause somewhere else.  
[22:03] <CarlFK> this seems very odd.
[22:05] <CarlFK> didn't touch it - crash - [174...] stack dump.  
[22:25] <smb_tp> CarlFK, Just a wild guess. Might try clocksource=jiffies (won't probably help with the crash, but there had been cases where it helped with pauses)
[22:35] <CarlFK> smb_tp: http://dev.personnelware.com/carl/a/pics/P1010005.JPG  pic of screen with "BUG: soft lockup - CPU#1 stuck for 160s! [swapper:0]"
[22:37] <CarlFK> smb_tp: guessing you are the smb that gave me http://people.ubuntu.com/~smb/bug254668 (same box, .27 kernel) 
[22:37] <smb_tp> CarlFK, Was that with the clocksource option or just the crash you mentrioned before
[22:37] <smb_tp> Yes, I am
[22:37] <CarlFK> hi
[22:37] <smb_tp> Hi
[22:37] <CarlFK> no ﻿clocksource
[22:37] <smb_tp> That one looks like somewhere in the usb code
[22:38] <CarlFK> here is it before the dump  http://dev.personnelware.com/carl/a/pics/P1010004.JPG
[22:39] <CarlFK> http://dev.personnelware.com/carl/a/pics/P1010003.JPG  same thing, better focus 
[22:41] <smb_tp> Yeah somewhere setting up the usb controller. The crash place is a bit strange in delay(). Hm... 
[22:46] <CarlFK>  http://dev.personnelware.com/carl/a/pics/P1010006.JPG "CPU1 stuck for 98s! [udevd:2033]"
[22:47] <CarlFK> let me know if you want me to open a lp tickit and  post these 
[22:48] <smb_tp> CarlFK, Yes, I just have a quick look into the code. Could you probably try the clocksource option meanwhile
[22:48] <smb_tp> ?
[22:48] <CarlFK> sure
[22:56] <cjwatson> 18:48 <cjwatson> yeah, Luke squeezed it in under the freeze last night
[22:56] <cjwatson> 18:49 <BenC> freeze?
[22:56] <cjwatson> oops, Ben left already
[22:56] <cjwatson> was going to remind him of this little thing called feature freeze ;-)
[22:58] <smb_tp> cjwatson, Probably he just forgot it was so close. :)
[23:01] <CarlFK> smb_tp: ﻿clocksource=jiffies - now it is stuck on "setting the system clock"
[23:02] <CarlFK> space/enter/type - shows up on console, doesn't un-pause it.  power button, nothing.
[23:04] <CarlFK> hit the "special dvd" button (hp laptop thing) - console shows "[11.8...] atkbd.c: unknown key released..." so it isn't froze just stuck 
[23:06] <smb_tp> CarlFK, Very strange. Something somewhere in the timers region. I'd say file a bug for 2.6.27 and probably include dmidecode data so its clear what system this is. At the moment, does SYSRQ-t print something? 
[23:12] <smb_tp> CarlFK, Since the oops happened in delay_tsc you might also try "notsc" to see whether that changes things.
[23:14] <CarlFK> k - I rebooted, and this time is slightly different: http://dev.personnelware.com/carl/a/pics/P1010009.JPG
[23:14] <CarlFK> hitting sysrq puts ^\ on the screen
[23:15] <CarlFK> what is ﻿SYSRQ-t ?  (trying to cord it just does ^\t )
[23:16] <smb_tp> CarlFK, Alt+Print+t
[23:19] <CarlFK> oh great - it fixed itself 
[23:20] <smb_tp> CarlFK, Just by waiting or after another boot
[23:21] <CarlFK> another boot - with clocksource=jiffies - which would hang till I power cycled it 
[23:23] <smb_tp> CarlFK, this really feels like timing/timer stuff. But I can't place it.
[23:23] <CarlFK> hmm - sudo apt-get upgrade "The following packages have been kept back:   hal libsmbios-bin ubuntu-minimal"
[23:24] <CarlFK> should I install those?  
[23:25] <smb_tp> CarlFK, I don't think they have some impact that early but it might be better to have a clean installation
[23:26] <smb_tp> CarlFK, well probably hal might
[23:28] <smb_tp> CarlFK, In any case, you should probably try the "notsc" option (instead of clocksource) and create a bug so this documented
[23:30] <smb_tp> CarlFK, I have to leave now, sorry
[23:30] <CarlFK> no prob
[23:31] <smb_tp> CarlFK, I uploaded another kernel to debug the other problem (it will still hang but prints more). But I did not have time to run it here, so you might want to wait or try it
[23:32] <CarlFK> smb_tp: bug report against .27 kernel ?
[23:32] <smb_tp> The crash yes
[23:32] <CarlFK> ill give it a shot - not like it will catch my box on fire :)
[23:32] <smb_tp> CarlFK, No rather more hanging :)
[23:33] <CarlFK> huh - hitting Alt causes a register dump
[23:33] <CarlFK> you better get going :)
[23:34] <smb_tp> CarlFK, Yeah, I better do... :)
[23:34]  * smb_tp runs
