| * kamalm frowns -- here's a puzzler - I sent my patch to LKML and cc: achiang more than 2.5 hours ago but it hasn't appeared on LKML (archive or my subscription) - I received my bcc: copy and I think achiang received the cc: copy but why hasn't it hit LKML? been plenty of other traffic since then. :-( | 00:47 | |
| cnd | kamalm: lkml has a delay | 00:50 |
|---|---|---|
| cnd | I don't know why exactly, but it's a multi-hour delay | 00:50 |
| achiang | kamalm: i got it twice, actually | 00:54 |
| kamalm | cnd: ah, okay then, that would explain it. By looking at the "Date:" headers on other messages, it appeared to me that there was no "extra" delay - i'll keep waiting | 00:54 |
| kamalm | achiang: I actually did re-send it again, after thinking that my excessively long To: line might have been the problem I fixed that and re-sent. (wasn't patient enough - oops). | 00:55 |
| achiang | nod | 00:55 |
| * cnd fears lkml too much to resend unless it's been over a day :) | 00:59 | |
| cnd | oh wait, kamalm, this is your acpi patch right? | 00:59 |
| kamalm | yes | 01:00 |
| cnd | did you send it to linux-acpi? | 01:00 |
| kamalm | yes | 01:00 |
| cnd | ok | 01:00 |
| kamalm | hasn't arrived there either | 01:00 |
| cnd | I don't think sending it to lkml is required as well | 01:00 |
| cnd | are you subscribed to linux-acpi? | 01:00 |
| kamalm | Documentation/SubmittingPatches said that you should also send to linux-kernel "unless you have a good reason not to" | 01:01 |
| kamalm | cnd: I think I'm not sub'd to linux-acpi | 01:01 |
| cnd | kamalm: ahhh, I learn something new every day then :) | 01:02 |
| kamalm | looks like LMKL might have a "greylist delay" thing going http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg149954.html | 01:03 |
| kamalm | cnd: re: linux-acpi -- I'm not subscribed but watching its archive page for my post to appear. I wonder if it accepts posts from non-subscribers. I *am* subscribed to LKML | 01:06 |
| achiang | kamalm: it does. i'm on it. your mail hasn't hit the list yet | 01:06 |
| achiang | kamalm: i'd recommend going for a beer or a walk. :) | 01:07 |
| achiang | and speaking of beer... it's about that time. :) | 01:08 |
| kamalm | i suppose I should be on it too... why not, just one more list, right? yeah, I've decided that it's probably a greylist delay so I'll just wait till tomorrow :-) beer sounds right. | 01:08 |
| * JFo recommends Crown Royal Black if you haven't tried it yet :) | 01:13 | |
| cnd | JFo: is that whisky? | 01:17 |
| JFo | cnd, yep | 01:17 |
| cnd | sounds good to me, but all I've got here is some jim beam | 01:18 |
| JFo | that works too :-) | 01:18 |
| * JFo goes off to refill his glass and watch a movie | 01:18 | |
| JFo | night all | 01:18 |
| cnd | at the rate I've been traveling though, I hardly need anything between my various trips | 01:19 |
| cmug | Hi. Does 10.04 have a kernel that has DMA remapping option enabled ? It is essential for kvm device passthrough virtualization | 07:11 |
| jk- | cmug: do you know the CONFIG_ parameter? | 07:15 |
| cmug | jk-, CONFIG_DMAR | 07:18 |
| cmug | CONFIG_DMAR=y | 07:18 |
| cmug | CONFIG_DMAR_DEFAULT_ON=y | 07:18 |
| jk- | # CONFIG_DMAR is not set | 07:19 |
| cmug | :( Is that same for every available kernel image ? | 07:19 |
| jk- | this is the generic flavour though... | 07:19 |
| cmug | yeah, perhaps there should be a linux-image-virtualization or something ? | 07:19 |
| jk- | doesn't look to be enabled in -server | 07:23 |
| cmug | :( I guess it's not called Experimental for no reason. But AFAIK it is crucial for the device passthrough functionality | 07:26 |
| cmug | and it's kind of a showstopper for me | 07:26 |
| jk- | not keen to build you own? | 07:27 |
| cmug | I like updates | 07:29 |
| jk- | everyone likes updates :) | 07:29 |
| cmug | Yeah | 07:29 |
| cmug | Maybe somebody can create a PPA with the kernel with DMAR enabled | 07:30 |
| cmug | maybe it already exists, don't know | 07:30 |
| jk- | i volunteer you to do that :D | 07:30 |
| cmug | I can do that if I knew how | 07:31 |
| cmug | Need to investigate | 07:31 |
| cmug | btw, is lucid released today (28th) ? | 07:31 |
| lifeless | no | 07:32 |
| lifeless | 29th | 07:32 |
| cmug | ok, I was just hoping since it is still 27th in the west coast of USA :) | 07:33 |
| dmarkey | too late to request something for 10.04 i assume? | 08:11 |
| jk- | given that it's out tomorrow, probably yes :) | 08:12 |
| dmarkey | aww :( | 08:15 |
| dmarkey | i'll wait till 10.10 then | 08:16 |

| akgraner | is this an issue for you all | 16:21 |
| JFo | I think they are wanting this to go into a day 0 update | 16:21 |
| akgraner | she is doing some livestreaming | 16:21 |

| jjohansen | csurbhi: so basically server team was looking for an update on ext4 performance and I haven't followed if there has been anything new recently | 16:31 |
| psurbhi | jjohansen, I havent done any benchmarks recently | 16:33 |
| psurbhi | and have not read anything on osnwes or phoronix report as well | 16:34 |
| jjohansen | psurbhi: okay, so basically the same status as at the sprint | 16:34 |
| psurbhi | yes | 16:34 |
| jjohansen | psurbhi: it came up because of this http://www.phoronix.com/scan.php?page=article&item=ubuntu_lts_perf&num=2 | 16:34 |
| jjohansen | looks like phoronix, rerunning the same tests again a couple weeks ago | 16:35 |

| alkisg | Hi, where can I find linux-image-2.6.32-20-generic? I can't find it in packages.ubuntu.com nor in http://kernel.ubuntu.com/~kernel-ppa/mainline/... I think it's the last one that'll boot with my intel 845 graphics card. | 17:28 |
| alkisg | (-19 boots, -21 doesn't, and I never tried -20) | 17:29 |
| JFo | alkisg, I have been fortunate enough to never need to go back to an older kernel that I hadn't installed | 17:32 |
| bjf | vanhoof, was going to add a launchpad plugin to it | 17:32 |
| JFo | bjf, any iodea where older kernels are located? | 17:32 |
| alkisg | JFo: I wish I was so lucky... :) | 17:32 |

| bguthro | I'm attempting to debug a suspend-resume issue with a new Dell Inspiron i3 based machine using the following methods: https://wiki.ubuntu.com/DebuggingKernelSuspend but am running into a brick wall. Was hoping for some other pointers. | 20:06 |
| bguthro | bjf says manjo might be a good resource...if you're around | 20:07 |
| manjo | bguthro, is the problem with suspend or resume ? | 20:08 |
| bguthro | Resume: Things seem to go down fine...but never come back. I always have to cold boot. | 20:08 |
| manjo | bguthro, what graphics card do you have ? | 20:08 |
| manjo | are you able to ssh to the box ? | 20:08 |
| bguthro | no. completely dead. The backlight doesn't even light up. The power light goes from pulsing, to solid...and I get a blip of the HDD, but then it is just stuck | 20:09 |
| bguthro | I've tried adding modules to the list to unload in /usr/lib/pm-utils/defaults - but no dice, so far | 20:10 |
| bguthro | I've also reproduced this on an i5 (also an inspiron) | 20:10 |
| bguthro | graphics card is the integrated i3 chip | 20:11 |
| bguthro | it uses the i915 driver, though | 20:11 |
| manjo | bguthro, have you tried using PM_DEBUG & PM_TRACE ? | 20:11 |
| bguthro | I tried the echo 1 > /sys/power/pm_trace - Is there more I can try? | 20:12 |
| manjo | bguthro, the instruction are in linux-2.6/Documentation/power/s2ram.txt | 20:12 |
| bguthro | I'll take a look, thanks | 20:13 |
| manjo | bguthro, also looks at basic-pm-debugging.txt | 20:13 |
| manjo | bguthro, its hard to remote help debug suspend/resume issues without real hw in front | 20:14 |
| manjo | bguthro, if you can try that then we can figure out the offending module / device | 20:15 |
| manjo | bguthro, also try with nokms | 20:15 |
| bguthro | will i915 still boot? I've had issues with that in the past... | 20:15 |
| bguthro | but I'll give it a shot | 20:16 |
| manjo | bguthro, ie nomodeset | 20:16 |
| bguthro | I guess I tried with i915.modeset=0 | 20:16 |
| manjo | ok | 20:17 |
| manjo | bguthro, All drivers: nomodeset - this will disable the kernel modesetting feature | 20:18 |
| bguthro | the only hash matches I got was against "tty tty57" - attempting with nomodeset now, but X doesn't seem too happy. I'm not getting any graphics | 20:23 |
| bguthro | plymouth came up (somewhat garbled) - and then it became unresponsive. | 20:24 |
| bguthro | yeah...even booting without "splash" - X fails to come up properly. | 20:26 |
| bguthro | unfortunately, this machine has no serial line, and no dock...so I can't even see if a trace is coming out or not. | 20:26 |
| manjo | bguthro, what model of dell is it ? | 20:39 |
| bguthro | testing all modes in /sys/power/pm_test succeed, but when I echo none to it, the system does not come back. According to the documentation, this suggests that it is in the invocation of the platform firmware | 20:39 |
| bguthro | It is an Inspiron 1434 | 20:40 |
| bguthro | sorry 1464 | 20:40 |
| manjo | bguthro, my dell contact is offline, I will check with him to see if there is a bios update for this | 20:40 |
| bguthro | also seen on a 1764 | 20:40 |
| manjo | or firmware | 20:40 |
| * manjo makes of note of the dell models | 20:41 | |
| bguthro | I updated the Bios today to the latest posted on the site. | 20:41 |
| bguthro | I did not check for firmware | 20:41 |
| manjo | bguthro, I will check on these models.. | 20:42 |
| bguthro | thank you | 20:42 |
| manjo | to see if they have any recommendations | 20:42 |
| manjo | bguthro, pm me your email | 20:43 |
| achiang | bguthro: that sounds a lot like what kamalm was working on. | 20:49 |
| achiang | bguthro: which kernel? | 20:49 |
| bguthro | 2.6.32-21-generic | 20:50 |
| achiang | bguthro: any chance you could try an upstream kernel? and pass acpi_sleep=sci_force_enable on the kernel cmdline? | 20:52 |
| kamalm | bguthro, achiang: the acpi_sleep=sci_force_enable feature looks like it was applied to Lucid http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=summary (see the Zhang Rui change) but I'm not sure where one would get a binary .deb which includes it. | 20:59 |
| bguthro | I'm not opposed to rebuilding myself. Should I just clone the git tree? | 21:00 |
| achiang | bguthro: this will be much easier: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc5-lucid/ | 21:01 |
| kamalm | ah yes, look at all those tasty kernels in .../mainline :-) thanks achaing | 21:02 |
| bguthro | will give it a try after filing the launchpad bug for manjo | 21:02 |
| achiang | bguthro: which bug is that? a bug for this s/r problem? | 21:03 |
| manjo | achiang, he is filing now | 21:03 |
| achiang | won't it just be dup'ed to whatever bug kamalm fixed with his recent patch that adds dell machines to the quirk list? | 21:04 |
| achiang | manjo: ^^ | 21:04 |
| achiang | kamalm: what was the LP bug for your dell fix? | 21:04 |
| manjo | achiang, yes if its the same bug | 21:05 |
| kamalm | achiang: nope -- my patch specifically adds 3 different "Dell Studio" models -- no effect on other models | 21:05 |

| * manjo typing impaired | 21:21 | |
| achiang | eh? | 21:21 |
| kamalm | bguthro: the symptoms do sound the same -- the acpi_sleep=sci_force_enable sounds like a good thing to try here. | 21:21 |
| bguthro | with .32 or the .34 referenced above? | 21:22 |
| achiang | kamalm: manjo: btw, i had a conversation with lenb on #acpi this am ; intel are aware of these crappy BIOSes coming out | 21:22 |
| achiang | not sure what action they plan on taking right now | 21:22 |
| achiang | maybe forceful beating about the head and shoulders with a cluebat | 21:22 |
| manjo | well dell says they do a good job of testing bios etc before they release machines ... | 21:23 |
| mjg59 | Well, everyone's signed off on the generic fix other than Len | 21:23 |
| manjo | I guess they test only with windows | 21:23 |
| achiang | manjo: i have some great property in florida i'd like to sell you too. ;) | 21:23 |
| manjo | achiang, how many acres do you have ? | 21:23 |
| kamalm | mjg59: the generic fix being to just force sci_enable on all the time? | 21:23 |
| manjo | I am not intersted in 42 | 21:24 |
| achiang | manjo: as many as you'd like. ;) | 21:24 |
| manjo | heh | 21:24 |
| mjg59 | kamalm: No, to do the register write if the system fails to set it itself | 21:24 |
| vish | hi.. I'm trying to use mainline kernel , but why is there no *all.deb for this kernel? http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.11-lucid/ | 21:24 |
| mjg59 | So, in order, follow the spec, do something that's mildly against spec, do something that wildly violates the spec | 21:25 |
| bguthro | OK, so .34 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc5-lucid/linux-image-2.6.34-020634rc5-generic_2.6.34-020634rc5_amd64.deb and the acpi_sleep=sci_force_enable flag seems to do the trick | 21:28 |
| manjo | bguthro, cool... can you throw that info in the bug ? | 21:28 |
| manjo | achiang, so this bad bios that vendors are aware of ? | 21:29 |
| bguthro | kamalm: Is this a generic flag in the .32 kernel - or is this only accepted upstream? (ie - can I Cherry-pick it for a build) | 21:29 |
| achiang | manjo: according to irc scuttlebutt, yes | 21:29 |
| achiang | maybe not dell, but lenovo are aware | 21:29 |
| manjo | bguthro, might be good to put that info in the bug ... I pointed jerone at it ... he will follow up with dell | 21:30 |
| bguthro | manjo: bug updated | 21:31 |
| manjo | thnx | 21:31 |
| kamalm | bguthro: as far as I know, the fix has been applied upstream -- we cherry-picked it from kernel.org (I think). | 21:31 |
| vish | folks, according to the map it seems 2.6.32-21.32is 2.6.32.11 mainline , but it doesnt have the *all.deb package.. how do i test with the mainline version then? [was asked to check for a bug] | 21:33 |
| vish | not there for > http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.11-lucid/ | 21:33 |
| achiang | manjo: still trying to understand this statement: " we track degu on ^^ #bug" | 21:34 |
| achiang | manjo: are you telling me to join a channel? | 21:34 |
| bguthro | kamalm: Same acpi_sleep=sci_force_enable added to 2.6.32-21-generic to no effect. Did this get cherry picked after this binary was built for us.archive.ubuntu.com? | 21:37 |
| manjo | achiang, my fingers did not follow my brain on that one | 21:37 |

| kamalm | bguthro: per http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=shortlog the acpi_sleep= feature was added 5 days ago and so first appears in 2.6.32-22. | 21:40 |
| kamalm | bguthro: I'm afraid I don't know how that relates to binaries on us.archive.ubuntu.com. | 21:41 |
| bguthro | kamalm: sounds like I'm one digit off. | 21:42 |

| arand | Is Bug #547182 correctly targeted towards linux (since it happens on nouveau but not on nvidia-blob)? | 23:37 |
| ubot3 | Malone bug 547182 in linux "Startup displays video artifacts from earlier 9.10 session" [Undecided,New] https://launchpad.net/bugs/547182 | 23:37 |
| arand | Could I at this point comfortably mark it as confirmed or should I look for more confirmation? | 23:37 |
| arand | If previous is true, should it be sent upstream? | 23:38 |
| arand | Finally, since it does display clear data from the previous session, is this to be considered as a security issue? (And is it a bug in Karmic rather, that doesn't clear the video buffer properly?) | 23:39 |
| manjo | arand, do you have a dual boot setup ? | 23:40 |
| arand | manjo: ubuntu kk & ll yes (and 3xWindows) | 23:43 |
| manjo | arand, does that commit you posted on the bug link fix the issue ? | 23:45 |
| arand | manjo: Ah, no. That's the version (and from what I know the specific commit) of the upstream kernel I tested, and confirmed that the issue is still present, on. | 23:46 |
| arand | I'll clarify that in a comment... | 23:46 |
