[00:11] <rtg> zul: I'm still having problems with xen x86. x86_64 build OK. The reason is that slow_down_io() in include/asm-x86/mach-xen/asm/io_32.h uses xen_io_delay() which is not correctly exported, or at least fails to link into vmlinuz. |
|
[00:38] <rtg> zul: ok, I fixed the xen 32 bit build with a gross hack on the xen patch files to have it call native_io_delay (like x86_64) instead of xen_io_delay. Feel free to send an update, but now it at least builds. |

[14:38] <tjaalton> rtg: yes, so lrm is ready to go? |
|
[14:38] <tjaalton> I've enabled ltmodem again, gentoo had a small patch to make it compile against .24 |
|
[14:39] <rtg> tjaalton: well, the kernel built for all arches. I'll bug an archive admin to ACCEPT it. |
|
[14:40] <tjaalton> and, made nvidia-glx* to depend 'lrm-VER-generic | nvidia-kernel-VER' instead of just the latter, because it's against policy to depend only on a virtual package and it's possible to get a wrong flavor kernel on upgrade |
|
[14:40] <tjaalton> like I get a -386 every time, and that doesn't even boot |
|
[14:44] <rtg> tjaalton: looks like the kernel has already been accepted into the archive. I just misread the state. |
|
[14:44] <tjaalton> rtg: cool, I'll do a test build and upload |
|
[14:44] <rtg> tjaalton: did you add openvz? I'm working on lum/lbm. |
|
[14:45] <tjaalton> hmm nope |
|
[14:45] <rtg> tjaalton: I'm wondering why you get a -386 kernel? Something wrong with meta still? |
|
[14:46] <tjaalton> no it's just apt trying to figure out what package to get to fulfill the dependancy, and uses the first in alphabetical order |

|
[14:51] <rtg> tjaalton: thanks |
|
[14:56] <tjaalton> rtg: is -openvz needed for lrm? there's no -virtual either |
|
[14:56] <tjaalton> and rightly so :) |
|
[14:59] <rtg> tjaalton: hmm, you are probably correct. Doesn't really make sense :) |
|
[15:00] <rtg> just like there is no xen version, right? |
|
[15:02] <tjaalton> xen is different, since you run dom0 on real hw |
|
[15:02] <tjaalton> but, it's not there.. hmm |
|
[15:02] <tjaalton> I know that it nvidia_new doesn't build for it, but |
|
[15:03] <tjaalton> -it |
|
[15:05] <tjaalton> hmm, there _is_ lrm for xen |
|
[15:08] <rtg> tjaalton: right, I forget about dom0 (cause I never use xen). But, I don't think openvz/virtual is needed for LRM. |
|
[15:14] <BenC> rtg, smb, amitk, cking: http://iso.qa.ubuntu.com/qatracker/subscriptions to track what ISO testing you will be expected to do |
|
[15:15] <BenC> rtg: virtual may need to be |
|
[15:15] <BenC> rtg: openevz maybe as well. A lot of the server tools (which can be used for dom0) are GUI |
|
[15:15] <BenC> rtg: *openvz ... anyway, if it compiles, might as well build it |
|
[15:17] <smb> BenC: Hm, I see the list but I am not sure I know how to interpret it... |
|
[15:17] <rtg> tjaalton: ^^ |
|
[15:19] <cking> BenC: any instructions on what to do? |
|
[15:19] <tjaalton> BenC: is openvz comparable to xen in this regard? -virtual isn't :) |
|
[15:21] <BenC> tjaalton: yes |
|
[15:21] <BenC> tjaalton: actually, you are right, we don't need lrm for -virtual |
|
[15:22] <BenC> but openvz is bare-metal and virtualized, so needs it |
|
[15:22] <BenC> (like xen) |
|
[15:22] <tjaalton> ok, I'll add it |
|
[15:36] <tjaalton> openvz is for amd64/i386? |
|
[15:40] <rtg> tjaalton: yep |
|
[15:42] <tjaalton> ok, let's see if it builds.. |

[15:42] <tjaalton> ..all the modules |
|
[15:54] <tjaalton> wow, it did |

[20:00] <blueyed> Does it make sense to provide virtualbox modules for Xen and OpenVZ kernels? IMHO yes, but I may be wrong. There are some for -virtual already. |

|
[20:01] <blueyed> zul: but you could run virtualbox inside of xen, can't you? |

[20:59] <Solarion> cat /proc/7285/mem says "No such process" |
|
[20:59] <Solarion> how does this make any sense? |
|
[20:59] <BenC> Solarion: what doesn't make sense? |
|
[20:59] <Solarion> it's sleeping but eating 100% cpu |
|
[21:00] <Solarion> mem says no such process |
|
[21:00] <BenC> sounds like a kernel bug or similar |
|
[21:00] <Solarion> that would be why I'm here |
|
[21:00] <Solarion> I want it dead. :) |
|
[21:00] <BenC> reboot |
|
[21:00] <Solarion> don't want to figure out the kernel bug with me? |
|
[21:00] <Solarion> I hate rebooting |
|
[21:01] <BenC> check dmesg |
|
[21:01] <BenC> but to get rid of it, you have to reboot |
|
[21:01] <Solarion> dmesg says nothing |
|
[21:01] <Solarion> ah, D is "disk sleep" |
|
[21:02] <BenC> I thought you knew that...the D is IO wait, basically |
|
[21:02] <Solarion> I didn't, but I'm figuring it out as I go along |
|
[21:02] <Solarion> the question is what is the kernel spinning on |
|
[21:02] <BenC> block device reads most likely (especially if it's playing as cdrom or something) |
|
[21:03] <BenC> cat /proc/7285/wchan |
|
[21:03] <Solarion> 0 |
|
[21:05] <Solarion> what is wchan? |
|
[21:05] <BenC> hmm...wchan doesn't seem to be producing useful info anymore |
|
[21:06] <Solarion> io isn't budging |
|
[21:06] <Solarion> (watch cat io) |
|
[21:07] <BenC> wchan is the function where the process is sleeping in the kernel |
|
[21:07] <BenC> Solarion: well, not much info to go on...I'd say reboot is your only option at this point |
|
[21:08] <Solarion> I want to know what happened tho |
|
[21:08] <Solarion> so it doesn't happen again |
|
[21:08] <BenC> So far, there's no way to see that |
|
[21:08] <BenC> you could try "strace -p 7285", but I suspect strace will lock up as well |
|
[21:08] <Solarion> it does |
|
[21:08] <Solarion> can you reset the ulimits? |
|
[21:08] <BenC> ulimits have nothing to do with it |
|
[21:08] <Solarion> e.g. make max open files 1 or something ridiculous? |
|
[21:09] <Solarion> part of it is trying to figure out how to kill it creatively. :) |
|
[21:09] <BenC> you can't |
|
[21:09] <Solarion> rebooting has no panache |
|
[21:09] <BenC> you cannot kill a 'D' state process |
|
[21:09] <BenC> it's stuck, and you have no choice but to reboot |
|
[21:09] <Solarion> and there's no way of figuring out where it's stuck and why? |
|
[21:10] <BenC> I've exhausted the known ways of figuring that out |
|
[21:10] <Solarion> stupid horked thing |
|
[21:13] <Solarion> wonder what totem is doing with xulrunner |
|
[21:13] <Solarion> totem 7285 solarion 44u sock 0,4 1464374 can't identify protocol |

[21:13] <Solarion> what is that (lsof output)? |
|
[21:28] <tjaalton> rtg: seems like it's not in 0.9.4 |
|
[21:29] <rtg> tjaalton: bummer.. then new AR5008 users are screwed for now. |
|
[21:29] <tjaalton> rtg: yeah |
|
[21:56] <infinity> rtg: Is there a new LRM on the way..? |
|
[21:57] <rtg> tjaalton: ^^ |
|
[21:57] <infinity> rtg: Updating -meta without updating LRM seems suboptimal. :) |
|
[21:58] <rtg> infinity: it shakes out eventually, doesn't it? |
|
[21:58] <infinity> rtg: Err, no... |
|
[21:58] <infinity> rtg: If you update meta first, kernels get upgraded without LRM. |
|
[21:58] <infinity> rtg: "linux-image-generic" gets upgraded, pulls in the new kernel, while "linux-generic" and "linux-restricted-modules-generic" get held back. |
|
[21:59] <infinity> rtg: So, boom, anyone not paying attention will reboot and have no network, video, whatever. |
|
[22:00] <rtg> infinity: my bad. I must not have any boxes using LRM or I would have noticed. |
|
[22:00] <infinity> rtg: Well, yes, it's my own fault for using evil binary blobs, but I suspect I'm not alone. ;) |
|
[22:00] <rtg> infinity: probably not. |
|
[22:01] <infinity> Anyhow, if LRM doesn't have a mess of pending changes, you could just do the ABI bump and upload to keep me happy. :) |
|
[22:01] <infinity> (If it does, you could still do the ABI bump, then followup with another upload later) |
|
[22:01] <tjaalton> infinity: I'm still figuring out why 32bit build fails now |
|
[22:02] <tjaalton> the -server flavour |
|
[22:02] <infinity> tjaalton: Oh, ick. |
|
[22:02] <infinity> tjaalton: Which module? |
|
[22:02] <tjaalton> nv.c:14: |
|
[22:02] <tjaalton> include/xen/interface/memory.h: At top level: |
|
[22:02] <tjaalton> include/xen/interface/memory.h:32: error: expected specifier-qualifier-list before 'GUEST_HANDLE' |
|
[22:02] <tjaalton> that's nv-new |
|
[22:02] <infinity> tjaalton: The most obvious question here is "why are we building nv stuff for -server at all?" |
|
[22:02] <infinity> I'm pretty sure I didn't back when I maintained it.. |
|
[22:03] <rtg> infinity: a surprising number of folks run the -server flavor on their desktop |
|
[22:03] <tjaalton> infinity: because someone want's to use vast amounts of memory on a workstation |
|
[22:03] <infinity> rtg: Which is, I suppose, their problem, not ours. ;) |
|
[22:03] <infinity> tjaalton: Define "vast"... |
|
[22:03] <tjaalton> 16gig? |
|
[22:03] <rtg> infinity: oh, I think some of the use is legitimate. |
|
[22:05] <infinity> See, 16GB doesn't sound that excessive to me anymore. |
|
[22:05] <infinity> What's the -generic kernel currently top out at? (My laptop only has 4GB, which works fine, so I'm not sure) |
|
[22:06] <tjaalton> mine too has 4Gb |
|
[22:06] <tjaalton> GB even |
|
[22:06] <tjaalton> anyway, 64bit build works fine |
|
[22:06] <tjaalton> something has changed in the headers? |
|
[22:07] <infinity> I'd guess. |
|
[22:07] <infinity> Time to get to bisecting? :/ |
|
[22:11] <tjaalton> well tbh it's not the latest headers it's using, but the first -13 upload |
|
[22:11] <tjaalton> I'll update the mirror |
|
[22:12] <rtg> tjaalton: the big change with server was CGROUPS, which seems to have fundamental effect on some low level macro. |
|
[22:13] <tjaalton> oh, I'm still building -13 :P |
|
[22:13] <rtg> tjaalton: there were about a zillion ABI changes which is what forced the ABI update. |
|
[22:13] <rtg> tjaalton: you definitely need -14 headers. |
|
[22:13] <tjaalton> hah, time to bump the abi again |
|
[22:13] <tjaalton> yep.. |
|
[22:13] <rtg> tjaalton: ok, I'm outta here for awhile. I'll check back in a few hours. |
|
[22:14] <tjaalton> rtg: ok, hopefully this works by then |
|
[22:15] <tjaalton> infinity: btw, check bug 188287 and the proposed solution (included in the lrm I'm testing). anything alarming you see? |
|

|
[22:19] <tjaalton> hm, still no -14 |
|
[22:21] <tjaalton> ..but now |
|
[22:24] <infinity> tjaalton: Well, "pure virtuals" violate policy, but in this case, it's hard to define a "preferred package", which is why it's always been this way... |
|
[22:25] <infinity> tjaalton: (For the record, this bug has existed for 3+ years) |
|
[22:25] <tjaalton> infinity: a tough one |
|
[22:25] <infinity> tjaalton: And only triggers during development cycles, generally, since we don't often update the nvidia drivers in released dists. |
|
[22:25] <infinity> (so, nvidia-kernel-$ver doesn't bump) |
|
[22:26] <tjaalton> infinity: but it does bump for dist-upgrades |
|
[22:26] <infinity> tjaalton: Yeah, true. But the dist-upgrader can be taught to cope with that. |
|
[22:26] <infinity> tjaalton: And we don't technically support people doing raw apt-get dist-upgrades. |
|
[22:27] <infinity> (We support packages not being absolutely broken, but we don't support people blindly telling apt "yeah, your package selection looks sane, I totally want 3 new kernels, and a removed openoffice!") |
|
[22:28] <tjaalton> infinity: I've also seen it doing a fresh install by preseeding the package list with nvidia-glx on it, but it doesn't always do that |
|
[22:30] <infinity> tjaalton: Yeah, if you ask apt to install "nvidia-glx linux-generic", it will install "nvidia-glx, lrm-386, linux-generic", because of its brain-dead dep resolution policy. |
|
[22:30] <infinity> It goes for "fastest loop unrolling" rather than "path of least possible system change" (which, say, dselect does) |
|
[22:31] <infinity> tjaalton: The problem with the proposed solution is that it just shifts the bug to all the other kernel:nvidia combinations, while appearing to "fix" it for generic. |
|
[22:32] <infinity> tjaalton: Given our general preference for generic, that may be a win, just pointing out that it's no more correct. ;) |
|
[22:32] <tjaalton> infinity: anyway, I'll drop the change for now, since it needs further discussion |
|
[22:34] <infinity> tjaalton: Given that one can never guarantee a kernel interface is there (because, y'know, the user might not reboot before hitting Ctrl-Alt-Backspace and blowing up X), I've often wondered if dropping the dep entirely, or even just lowering it to a Recommends, might not be out of line. |
|
[22:34] <infinity> tjaalton: userspace:kernel dependencies are much harder to enforce than kernel:kernel or userspace:userspace, since we have no control over which grub option they select on boot. |
|
[22:35] <tjaalton> hmm.. true |
|
[22:36] <infinity> tjaalton: One will note that the fglrx packages have no such painful userspace:kernel dep. |
|
[22:36] <tjaalton> infinity: because there's only one version? |
|
[22:36] <infinity> tjaalton: No, the driver->kernel dep is OLD... Predates the multiple version thing. |
|
[22:37] <infinity> tjaalton: It's just inherited from the Debian nvidia packaging. |
|
[22:37] <tjaalton> oh |
|
[22:37] <infinity> tjaalton: The multiple version thing is a red herring, since the LRM packages provide all 3 kernel modules. |
|
[22:38] <tjaalton> yep |
|
[22:38] <infinity> tjaalton: But, yeah, in every release cycle, I see maybe one complaint about fglrx lacking a kernel dep, and dozens of complaints about the nvidia kernel dep being broken. |
|
[22:39] <infinity> tjaalton: Given that fantastic bit of statistical analysis, I'd say the fglrx situation is "less broken". |
|
[22:39] <tjaalton> infinity: hehe :) |
