[07:48] <fairuz> morning people
[12:30] <fairuz> What does SW acknowledge means?
[12:30] <fairuz> (to clear an interrupt)
[12:31] <ohsix> its a bit the software handling the irq can set to tell the hw that it knows about the last one
[12:31] <ohsix> usually to let the hw know its ok to discard something or move on
[12:43] <fairuz> ohsix: so normally writing 1 to the acknowledge register will do the job right?
[12:45] <ohsix> i dunno your circumstances, if that's what does it then yes
[12:52] <fairuz> Actually I cleared the interrupt but it stills reenter the handler 
[12:53] <fairuz> so obviously there is something else that i'm not clearing :D
[13:58] <KNRO> can anyone take a look at this? http://ubuntuforums.org/showthread.php?t=650521
[13:58] <KNRO> is it possible to use pbuilder to build packages for kernel modules?
[14:13] <dns53> how do i get from a busybox console to a booting system?
[14:51] <tgardner> ogasawara, looks like you're still on the hot seat for another week.
[14:51] <ogasawara> tgardner: indeed, just saw the calendar
[14:52] <smb> tgardner, ogasawara I had been even thinking that it might be one week after that
[14:52] <tgardner> ogasawara, at least the beer in Budapest is cheap. approx 1.8USD per pint :)
[14:54]  * tgardner --> ESXi install
[15:28]  * ogasawara back in 20min
[16:13] <mahmoh> does anyone know how to override the bios for kvm support with a kernel option?  kvm=enable?
[16:14] <tgardner> mahmoh, you generally have to enable virtualization in the BIOS
[16:17] <mahmoh> tgardner: I did but it's still reporting it's disabled in the bios, and I updated to the latest bios with the same results
[16:19] <mahmoh> ah, I might have to disable trusted execution on my dell hardware it appears ...
[16:19] <mjg59> mahmoh: If it's reporting that it's disabled by the BIOS then the BIOS has (a) not enabled support and (b) has locked the MSR
[16:20] <mjg59> And yes, if trusted execution is enabled and you want to use kvm then you may need to boot in a trusted setup
[16:21] <Krunch> you may also try to poke at the MSR manually http://timetobleed.com/enabling-bios-options-on-a-live-server-with-no-rebooting/
[16:22] <mahmoh> there we go ... how much more confusing can they make it?
[16:23] <mahmoh> mjg59: I'm guessing there's no kernel override then ;)  disabling the trusted execution worked (whew), so no problems anymore
[16:24] <mahmoh> except with Dell'
[16:24] <mahmoh> s bios that is
[16:24] <mahmoh> mjg59: thx
[16:24] <cking_> why doesn't that surprise me
[16:26] <mahmoh> Krunch: now that looks like fun!
[16:27] <mahmoh> cking_: ;)
[16:27] <mahmoh> cking_: I was just thinking about you
[16:27] <Krunch> mahmoh: don't try this at home (well, maybe better at home than on your production server)
[16:27] <mahmoh> oops, I just took out EC2
[16:29] <mahmoh> thx all
[16:31]  * bjf -> dr. appt.
[16:47] <ogasawara> pgraner: I see we don't have a specific kernel track for UDS, so I'm assuming we'll just throw our blueprints/sessions under the Foundations track?
[17:02]  * tgardner --> back to the server room
[17:59] <jjohansen> manjo`: ping
[18:24] <manjo`> jjohansen, pong
[18:24] <manjo`> sorry was out for lunch
[18:24] <jjohansen> manjo`: so I installed 64bit natty on the x120e
[18:25] <manjo`> jjohansen, and ..
[18:25] <jjohansen> manjo`: I'm not sure where you want to go with the bug from hear,
[18:25] <manjo`> so that means you are not seeing the bug ? 
[18:25] <jjohansen> manjo`: basically the rtl driver needs to be removed during the install
[18:25] <jjohansen> manjo`: no I saw it plenty
[18:26] <jjohansen> manjo`: I updated Bug #744419
[18:26] <ubot2> Launchpad bug 744419 in linux "[NATTY] [ Kernel oops installing natty @tty_write()" [Undecided,New] https://launchpad.net/bugs/744419
[18:26] <manjo`> hmm... not sure how we can fix that for natty... probably have udev rules that removes it ? 
[18:27] <manjo`> udev rules based on DMI info ? 
[18:27] <tgardner-afk> manjo`, blacklist in /etc/modprobe.d ?
[18:27] <manjo`> tgardner-afk, right or that ... 
[18:27] <jjohansen> manjo`: could black list it for the install disk, I'm not sure you want to black list for after, it seems to be working (for some value of working)
[18:28]  * manjo` writing to mmany udev rules these days 
[18:28] <manjo`> jjohansen, also can you install cheese and see if you can record video... the camera is not recording video and showing a blank screen on that one 
[18:29] <manjo`> jjohansen, what would the rtl driver cause this bug ? 
[18:29] <jjohansen> manjo`: hrmm give me a sec, I have cheese installed in both 32 and 64 bit but I never tried grabbing video
[18:29] <jjohansen> manjo`: I haven't chased it far enough to figure that out
[18:30] <jjohansen> manjo`: it took me a lot just to get the stupid thing installed, that was my limit for the weekend
[18:31] <manjo`> jjohansen, yeah natty is very busted on that x120e
[18:31] <manjo`> jjohansen, also if you switch your bios to legacy only and don't look for UEFI you will have better results 
[18:31] <jjohansen> manjo`: hrmm, I don't know about that, I haven't found it any worse than natty on any of my other machines, all of which have problems
[18:32] <jjohansen> manjo`: also I just did a bios update on it this morning so we will see if that helps anything
[18:36] <jjohansen> manjo`: yep cheese crashes trying to record video
[18:36] <manjo`> jjohansen, it does the same on maverick too.. thanks for the confirmation 
[18:36] <manjo`> jjohansen, this is with the latest bios update as well right ? 
[18:38] <jjohansen> manjo`: yep
[18:43] <jjohansen> manjo`: so cheese gets stuck in a polling loop on fd 3
[18:43] <jjohansen> manjo`: which is returning EAGAIN
[18:44] <manjo`> you think its a cheese bug ?
[18:45] <jjohansen> manjo`: well there is definitely a cheese bug there, it shouldn't let a device returning EGAIN send it into an infinite polling loop but the device isn't responding to the request
[18:45] <jjohansen> so at least 2 bugs
[18:45] <kamal> ls
[19:03] <kamal> tgardner: should there be an oneiric dchroot on tangerine?  (is an oneiric dchroot even possible at this point?)   I'm building the ubuntu-oneiric kernel in a natty chroot on tangerine now, fwiw.
[19:07] <tgardner> kamal, not yet
[19:09]  * kamal expects the natty chroot to work for ubuntu-oneiric anyway, so np
[19:12] <kamal> confirmed: ubuntu-oneiric kernel builds okay in a natty dchroot
[19:12] <ogasawara> kamal:  I've pushed the latest oneiric bits to zinc.  it should build successfully now on i386 and amd64.  about to boot test and then build test on armel.
[19:14] <kamal> ogasawara: ok, thanks -- I'm about to try booting my amd64 oneiric kernel too
[19:14]  * ogasawara crosses fingers for kamal
[19:14]  * kamal readies the fire extinguisher ;-)
[19:19] <sconklin> severe weather due here in the next 90 minutes - if I drop out that's why
[19:55]  * bjf -> lunch
[20:08] <kamal> ogasawara: fyi, my oneiric amd64 kernel seems to work fine (Dell Studio Core-i5 laptop with Intel graphics)
[20:09] <ogasawara> kamal: cool, thanks for the feedback.  working here for me too.
[20:32]  * tgardner --> server room (one more time)
[20:38] <kamal> mjg59: got a moment to discuss intel_backlight in 2.6.39?
[20:40] <mjg59> kamal: Sure
[20:40] <kamal> hi Matthew ...
[20:40] <kamal> it looks like most of your backlight work has landed in 2.6.39...  I do see "backlight: add backlight type" and the nv_backlight and radeon_backlight bits, but the intel_backlight patch itself ("i915: Add native backlight control") appears to be missing.
[20:40] <kamal> do we know why that's the case?
[20:42] <mjg59> We do not
[20:42] <mjg59> I suspect it conflicted and Andrew dropped it
[20:42] <mjg59> Let me try that again, then
[20:42] <kamal> ah
[20:43] <kamal> ok, I'll keep an eye on the repo (and intel-gfx?) for your retry...  and will try cramming your previous version in myself to test in the meantime.
[20:45] <kamal> mjg59: I'm glad I asked!  ;-)  thanks for the info (and the patches, of course!)
[20:58] <sforshee> mjg59, if you've got a minute, I was wondering about the fate of this patch: https://lkml.org/lkml/2011/1/19/331
[20:59] <sforshee> the conversation seemed to die without a resolution
[20:59] <mjg59> sforshee: I think I need to rewrite it from scratch
[20:59] <mjg59> sforshee: I'm also worried about it breaking other systems
[20:59] <mjg59> sforshee: But it's on my list - I was thinking about it today
[20:59] <mjg59> It needs some infrastructural changes from ACPI to get the EC handle
[21:00] <sforshee> mjg59, yeah, the driver does seem pretty ugly
[21:00] <sforshee> that patch does get some systems working though
[21:00] <mjg59> I was going to just rewrite toshiba_acpi completely at some stage
[21:00] <mjg59> I guess I should do that on the plane tomorrow
[21:01] <sforshee> mjg59, looking forward to seeing the results :-)
[21:01] <sforshee> thanks for the update
[21:30] <sconklin> power is intermittent here, will probably drop out here in a bit
[21:38] <mjg59> sforshee: If you'd like to test http://fpaste.org/R8HI/ that would be great
[21:38] <mjg59> sforshee: Wait, sorry, not you
[21:38] <mjg59> kamal: If you'd like to test http://fpaste.org/R8HI/ that would be great
[21:38] <mjg59> kamal: I've build-tested it, but nothing more
[21:39] <kamal> mjg59: absolutely, I'll give it a spin right away
[22:07]  * ogasawara back on later
[22:37] <kamal> mjg59: wonderful!  that patch works just fine on top of ubuntu-oneiric (2.6.39-rc1-ish).
[22:38] <kamal> mjg59: feel freel to add my Tested-by: Kamal Mostafa <kamal@canonical.com>
[22:40] <mjg59> kamal: Excellent
[22:41] <mjg59> manjo`: Does your X120e have the rtl wifi?
[22:42] <mjg59> manjo`: If so, are you seeing stalls when it tries to request_firmware() on resume?
[22:43] <manjo`> mjg59, looking ... 
[22:45] <manjo`> mjg59, yes it has rtl8192ce ... and I don't see stalls
[22:46] <mjg59> manjo`: Ok. Using rtlwifi, or using the realtek driver?
[22:46] <manjo`> it resumes ok (I am on 10.10) 2.6.35-28 
[22:46] <mjg59> Ah, the realtek one. Ok.
[22:46] <mjg59> So rtlwifi is just buggy. I'll work on that.
[22:46] <manjo`> yep I am not on rtlwifi
[22:46] <manjo`> I am using the realtek driver 
[22:48] <jjohansen> mjg59: yes the rtlwifi driver is very buggy, and yes I see stalls coming out of suspend sometimes, have also had coming out of suspend lock up
[22:50] <mjg59> jjohansen: Yeah, I've just added it to the pm-utils unload/load blacklist for now
[22:51] <jjohansen> mjg59: the rtl8192ce driver is also responsible for the 64 bit install failures
[22:51] <mjg59> jjohansen: Ok, not something we've seen
[22:52] <jjohansen> mjg59: hrmm, Bug #744419
