JanC(what your issue is exactly caused by)00:13
adincJanC: it is not only my issue00:20
JanCyeah, I saw the bug00:20

adincJanC: so i wonder how this device works for you00:20
JanCbut it works fine for me, so I guess the driver can work properly00:20
adincthat would be great00:20
JanCmaybe it's just not working fine on some variations or combinatiosn with other hardware?00:21
adincbut unfortunately it doesn't here, i'm just downlaoding the kernel sources in order to make use of the bugfix from mohamed abbas00:21
adincJanC: possible, but how should we figure this out, i'm not very well involved into driver programming for wireless devices. we wouldneed to do a lot of work, theonly ones who could do this actually are the developers00:22
adincof this driver00:22
adinccool the kernel now supports hsdpa00:23
JanCI guess the Intel developers, with some help of the Ubuntu kernel developers, would be the best people to investigate  ;)00:23
adincyes, you are right, but as i can see there is already work done.00:24
JanCmight be, looking at that comment00:25
adincJanC: which kernel version are you running?00:25
adinccomment 2500:25
JanClatest hardy kernel available this afternoon (8 hours ago or so)00:26
JanCmaybe 10h00:26
adincthere hasn't beeen any kernel changes in hardy, was there?00:26
adincif you do a uname -a, what do you get?00:26
JanCI haven't checked in the last 8-12h  ;)00:26
JanClet's check on my laptop00:26
JanCkernel build based on linux-meta, which seems to be the last (according to packages.ubuntu.com)00:30
adinci've 2.6.24-12-generic00:31
JanCyeah, that's what uname says00:32
adincso your kernel is 2.6.24-12-generic?00:32
adinci suppose uhu means yes00:33
JanCyes ツ00:33
adinci don't know the numbering you showed above, there must be a mistake in your kernel versioning scheme00:34
JanCmy laptop seems to have a 3945 "rev 2" wireless with PCI-ID 8086:4222 00:38
JanCthe version number I showed is for the kernel meta package--it shows the internal build number used by the Ubuntu kernel developers I suppose00:39
adinchere are the kernel packages listed00:40
JanClinux-meta is the source package (it's called "meta" because it builds several different kernals)00:42
JanCsee http://packages.ubuntu.com/hardy/linux-generic and then in the bar at the right00:42
JanCanyway, it's just an internal Ubuntu kernel version number00:43
adinci see00:43
adincis there a way to see when the latest kernel was published for ubuntu hardy?00:44
JanChttp://packages.ubuntu.com/source/hardy/linux-meta should be pretty up-to-date00:45
JanCotherwise, if you update hardy from the main servers, it should be obvious  :-)00:45
adinca dist-upgrade i suppose would download the latest kernel build, wouldn't it00:47
JanCyes, it should00:47
JanCwhat device ID does 'lspci -nn' give for your wireless?00:49
JanCor 'lspci -n' maybe00:49
JanChm, so it's supposed to be exactly the same hardware00:50
adincJanC: have you got a smp kernel?00:54
adincsomehow a dual core or more than one cpu?00:54
JanCthe -generic kernel is SMP  ツ00:55
JanCand I have a Core Duo, so it's actually using SMP too00:55
JanCfro mthe upstream bug report: """Guess what... I enabled the iwl3945 debugging (and disabled CGROUPS to get system back to usable state), and problem is no longer reproducible easily."""00:56
JanCsounds like a fun bug to "debug" that way  ;-)00:56
adinci'm compiling the kernel now.00:57
adincdoes he mean debugging enabled by adding something like debug=0x44444 for modprobe iwl394500:57
JanCsomething like that00:58
adincwhat about cgroups?00:59
JanCif I understand things correctly (but I am not a kernel devloper in any way), it seems like the firmware crashes or gives errors when it's under load (sometimes)01:03
adinci think that is a different bug01:03
adincwhen the module loads a firmware, which is the case when the device is configured, then the problem appears01:04
Nghas the behaviour of cpu frequency scaling intentionally changed since <=gutsy?07:28
Ng /sys/devices/system/cpu/cpu1/cpufreq is a symlink to cpu0/cpufreq07:29
Ng(which gets lost on suspend/resume because we save the value of each and then reset it to performance for the actual suspend)07:31

sorenI have a laptop that since upgrading to hardy doesn't suspend nor hibernate anymore. Both end up with a blank vt with a blinking cursor in the top left corner. AFAICS, all the quirks listed on the pm-{suspend,hibernate,suspend-hybrid} man page deal with the resuming process..09:51
soren..so I'm at a bit of a loss. What to do?09:51
chaosmastersoren: what laptop do you use and what is your graphics card?09:52
sorenI believe it's called a Uniwill something-something. It's got Intel graphics.09:53
sorenSuspend and hibernate have both worked flawlessly since breezy on it, afair.09:54
sorenHm... I could try booting the gutsy kernel.09:54
chaosmastersoren: please paste the output of: lspci | grep VGA09:54
sorenThat might provide a hint as to whether it's a pm-utils issue or a kernel on.e09:55
chaosmastersoren: not really :)09:55
sorenIt's an intel 855.09:57
sorenchaosmaster: Why couldn't booting an older kernel provide a hint as to whether it's a pm-utils issue or a kernel one?09:57
chaosmastersoren: the suspend/resume process is very delicate and complex with a lot of parts beeing integrated. in Hardy a lot of new technologies (kerne, xorg, pm-utils) are updated so it's not that easy to pinpoint it to a single part09:58
sorenEr... Sure it is.09:58
sorenDon't start X, boot an older kernel, and presto! All you've got left is the new pm-utils.09:58

mjg59Ng: What sort of different behaviour?12:34
Ngmjg59: well specifically for me I need to unload e1000 for suspend to work, which acpi-support did because it seems to unload all network modules, where pm-utils doesn't unload any modules by default (if I was reading the scripts properly)12:35
mjg59Ok. Have you got a bug filed about that?12:36
Ngmjg59: I filed one originally about suspend not working, which I've kept updated, bug 201037. It may need to be moved to a different package or so12:37

sorenI'm leaning towards less.12:38
sorenIt's easier to mark a bug a as a dupe than to split it into two.12:38
NgI can't answer that, but I would guess this affects more than just the x300 and it's a fairly significant behaviour change that's very undiscoverable. the price of unloading/reloading networking modules can't be very high, but it may make some weird problems go away.12:39
Nghaving said that, it just seems like its masking driver bugs12:39
Nganyway, I'll stop hijacking soren's bugtime ;)12:40
sorenFWIW, I think don't-unload-by-default would be a good idea early in the dev cycle and then switch to unload-by-default at around beta time.12:41
NgI'd buy that for a dollar12:42
sorenIt gives us a chance to spot the issues and perhaps fix them early on, and then switch to the safer approach for the release.12:42

sorenThe bug tjaalton linked to suggested that it'd end up in an infinite loop. I've left the machine alone for a while and the fan is rather quiet, so I have a hunch that's not it.12:52
sorenmjg59: Without i915, it suspends just fine.12:55
mjg59soren: Yeah, the failure we've seen with hibernate shouldn't happen on suspend12:59
sorenmjg59: Oh?12:59
mjg59It's specific to the suspend call being made twice13:00
mjg59Which only happens in hibernate13:00
sorenOh, ok.13:01
soren(hibernate works just fine now, too)13:01
sorenWhy does hibernation cause two calls to the suspend code?13:02
mjg59Because it's somewhat broken13:02
mjg59soren: Hm. Ok. Anyway, on the off-chance that it's actually the same problem - any chance you can grab the oops on hibernation?13:03
mjg59Camera or something would be good13:03
sorenJust modprobe i915 and recycling X should do the trick, I guess.13:05

smbBenC: Morging Ben. One question: I was looking over the milestone bugs and there is one (bug 176090) assigned to Tim which is about iwlwifi. Does it make sense to add LED support (kernel driver would have that but is different version)?13:07

BenCsmb: Is it just a matter of enabling the right config option?13:07
sorenmjg59: Hm... Guess not. It looks suspiciously like a font-less vc.13:08
smbBenC: No, there is more code change involved13:08
BenCsmb: looks to me like enabling MAC80211_LEDS would do the trick...what else is there?13:08
mjg59soren: Heh. Well, if you can get it again, that would be helpful :)13:09
sorenmjg59: I'm on it, I'm on it. I think my phone takes decent enough pictures to be useful. Do you happen to know of a relevant bug to attach it to, or should I just throw them somewhere for you to see.13:09
smbBenC: If I am not wrong, it requires *-led.c files in both specific drivers and at least one other file that isn't there right now (something with hbus)13:10
smbBenC: if you want a quick look. I just moved the patch that enabled leds to zinc (my home)13:11
mjg59soren: Just file a new one for now13:12
smbBenC: It might be doable. I just wanted to be sure it is agreed because there there certainly is a reason we use the lum driver and not the kernel version13:15

mjg59soren: Heh23:27
sorenmjg59: A bit before i915_suspend+0x60, there's a "call 1b6", which is one byte into the call instruction.23:27

keescookthe disassembly is showing a busted compiler -- a -3 relative jump target is nonsense.23:33

sorenjbarnes: Hang on, I'll reboot it.23:33
jbarnessoren: no it probably wouldn't generate bad opcodes, rather bad memory requests23:34
jbarnesand/or might overwrite important stuff23:34

sleepstercan you guys recommend maybe.. an easy device driver I could implement to learn?23:46
jbarnessoren: where are the original oopses again?  do you have a complete dmesg from the machine possibly?23:47
sorenjbarnes: The oops happens as I hibernate, so it's unresponsive after it.23:48

sleepsterthanks guys for the info23:50
sleepsterit's much appreciated23:50
sorenjbarnes: The what now?23:50
jbarnessoren: I think the cause is the "unable to handle paging request at ..."23:51
jbarnesand 0xdfcef0a4 is the addr23:51
sorenjbarnes: How do I translate that into something useful?23:52
keescooksoren: where is the +0x60 coming from?23:52

keescookah, the photos from 207098 are 0x51d, then?23:53

jbarneswhich corresponds to 72a:8b 80 a4 20 00 00    mov    0x20a4(%eax),%eax23:54
sorenkeescook: Yes.23:54
jbarneswhich is why I suspected the fbc regs at first, since they're at 0x2xxx23:54
jbarnesbut now I think your whole register window is getting lost somehow23:54
sorenI'll see if I can get the +0x60 oops again and take new photos. Gimme a few minutes.23:55
mjg59jbarnes: Hm. This is without the diff that ensures suspend only gets usefully called once23:55

jbarnesmjg59: we'll disable the device in the suspend path23:56
mjg59jbarnes: Ah. Perhaps that's the issue.23:56
jbarnesbut it could also be X somehow unmapping the regs23:56

jbarnesbut there may be a specific interaction with the versions you have on your system23:57
