[00:29] <pwnguin> is there a reason bug #137686 isn't marked fix released? |
|
[11:18] <elmargol> Hibernation almost works here. It terminates everything and copies the ram to the sawp. The only problem is the laptop (dell inspiron 9400) does not power off. I have to hold the power key in order to do this. Resuming works perfect! |
|
[11:18] <elmargol> Is there a way to fix this? |
|
[13:18] <abogani> tjaalton: Hi Timo! Are you around? |
|
[13:19] <laga> elmargol: have you seen the freedesktop.org page about power management? |
|
[13:19] <tjaalton> abogani: hey, seems that I am ;) |
|
[13:20] <abogani> tjaalton: Sorry to bother you about lrm... :-) |
|
[13:20] <abogani> Is there a chance to have nvidia closed drivers updated to 173.08 (actually marked by Nvidia as Beta) in 8.04.1 ? |
|
[13:20] <tjaalton> abogani: doubtful, but there should be a stable version soonish |
|
[13:21] <tjaalton> that version has some pretty severe bugs |
|
[13:21] <abogani> :-( |
|
[13:21] <laga> elmargol: http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-index.html |
|
[13:22] <tjaalton> abogani: phoronix had something about it, let me check |
|
[13:28] <tjaalton> abogani: ok here it is: http://www.phoronix.com/scan.php?page=news_item&px=NjQzMA |
|
[13:29] <tjaalton> 2D slowdowns |
|
[13:30] <abogani> gosh! |
|
[13:31] <tjaalton> hm, I really should update the lrm for intrepid |
|
[13:31] <mjg59> laga: That's not usefully relevant in this case |
|
[13:31] <laga> mjg59: it was worth a try. :) |
|
[13:32] <abogani> tjaalton: Some -rt users report problem with nvidia stable version and GLX that stop to works! :-( |
|
[13:32] <tjaalton> abogani: yep.. |
|
[13:51] <alex_joni> hi abogani |
|
[13:52] <abogani> alex_joni: Hi Alexandru |
|
[13:53] <alex_joni> abogani: I talked to BenC about pushing -rtai stuff to ubuntu |
|
[13:53] <alex_joni> and I don't think it's important enough (enough users) that it's worth the effort |
|
[13:55] <abogani> alex_joni: Is it your opinion or the BenC one? |
|
[13:56] <alex_joni> abogani: well.. I'm not sure if I can support it once it's pushed into ubuntu |
|
[13:56] <alex_joni> (building/testing on each new release, etc) |
|
[13:58] <abogani> I understand well your doubts. |
|
[13:58] <alex_joni> abogani: anyways, I have a repo for the -rtai stuff |
|
[13:58] <alex_joni> so if you're interested, feel free to use it |
|
[13:59] <abogani> Thanks! It is very good news! |
|
[13:59] <abogani> URI? |
|
[14:00] <alex_joni> abogani: http://www.linuxcnc.org/hardy/ |
|
[14:01] <abogani> Great! |
|
[14:02] <SEJeff> alex_joni, Do you use rtai for robotics? How does the latency compare to a mainline kernel if you don't mind my asking? |
|
[14:02] <alex_joni> SEJeff: we get about 10-20 usec latency on rtai |
|
[14:02] <SEJeff> alex_joni, As opposed to? |
|
[14:02] <alex_joni> the -rt is still quite away from that afaik |
|
[14:03] <SEJeff> Yeah I've used Xenomai, but it is more about pretty code than low latency |
|
[14:03] <alex_joni> Xenomai shouldn't be much worse than rtai |
|
[14:03] <alex_joni> but it depends on the skin you use |
|
[14:03] <abogani> ~10 times more |
|
[14:04] <alex_joni> abogani: you mean -rt .. right? |
|
[14:05] <abogani> Yes. In any case with CPU Isolating (or called CPU Shielding) you can achieve very similar performance. |
|
[14:05] <SEJeff> alex_joni, Well which personality do you suggest for best case low latency |
|
[14:06] <alex_joni> SEJeff: I didn't try xenomai enough to say |
|
[14:06] <alex_joni> but the best latency I've ever seen was with RTAI on a SMP intel system |
|
[14:06] <abogani> I always use POSIX skin. |
|
[14:06] <alex_joni> with isolcpus, and RTAI only on one core |
|
[14:06] <alex_joni> on one system it had something around 4-5 usec latency |
|
[14:06] <SEJeff> alex_joni, latency for network or applications? Intel nics with e1000 have the lowest latency on the market |
|
[14:07] <alex_joni> SEJeff: I'm only talking about realtime apps |
|
[14:07] <elmargol> laga, thx for the link |
|
[14:07] <SEJeff> alex_joni, Ah, I work at a stock trading company as a Linux guy. Lots of -rt interest |
|
[14:08] <alex_joni> SEJeff: for that, -rt might be better |
|
[14:08] <SEJeff> alex_joni, -rt is higher latency, but more deterministic than the normal kernel |
|
[14:08] <SEJeff> One of the reasons for the rtai / xenomai split is because rtai only cares about the lowest latency. It would be huge to have easier to use rtai kernels |
|
[14:09] <alex_joni> SEJeff: might be a bit OT for #ubuntu-kernel.. shall we move to another channel? |
|
[14:10] <SEJeff> alex_joni, Sure where? |
|
[14:10] <alex_joni> #rt-and-stuff :) |
|
[14:13] <xhaker> can someone help me with -server ? |
|
[14:13] <xhaker> i can't get it to boot on a pentium M |
|
[14:13] <xhaker> found a bug filed already |
|
[14:14] <xhaker> bug #222253 |
|
[14:14] <xhaker> but there doesn't seem to be much attention |
|
[14:15] <xhaker> rtg: ^ |
|
[14:28] <xhaker> subscribed ubuntu-kernel-server |
|
[14:35] <xhaker> subscribed ubuntu-kernel-team also, u-k-s doesn't seem to be used for bugs :) |
|
[14:36] <rtg> xhaker: does the -generic kernel boot? |
|
[14:37] <rtg> I can't tell from the LP report what is being attempted, -server or -generic. |
|
[14:40] <xhaker> rtg: it's server.. whatever ubuntu-server-i386.iso installs |
|
[14:41] <rtg> xhaker: do you have one of the VIA C3 procs? |
|
[14:41] <xhaker> and yes, -generic worked |
|
[14:41] <xhaker> rtg: pentium M |
|
[14:41] <rtg> xhaker: ah, thats what I wanted. |
|
[14:41] <xhaker> it seems specific to -server |
|
[14:42] <rtg> xhaker: the big diff might be PAE. I'll be back in a bit.... |
|
[14:42] <xhaker> rtg: ok |
|
[14:59] <tjaalton> rtg: I'll do a bugfix lrm for hardy-proposed first, then try to get it to build against intrepid. is that ok? |
|
[14:59] <tjaalton> (sorting out the libwfb mess & authatieventsd.sh) |
|
[15:00] <rtg> tjaalton: thats fine. I'm not in a big hurry for Intrepid LRM since I'm kind of buried under SRUs at the moment. |
|
[15:00] <tjaalton> rtg: heh, same here |
|
[15:55] <xhaker> rtg: CONFIG_X86_PAE=y on -server only |
|
[15:55] <rtg> xhaker: yes |
|
[15:55] <xhaker> is there any boot option to disable it so i can see if it boots? |
|
[15:56] <rtg> xhaker: no, its a feature of the page table that is hardwired into the mm. |
|
[15:57] <rtg> xhaker: what is it about the -server kernel that is attractive for the VIA C3 cpu? |
|
[15:57] <xhaker> rtg: people are using the server ISO to setup their home servers.. mine runs pentium M but people buy via c3 cpus for the low Wattage |
|
[15:58] <xhaker> what other way to setup a lean and mean home server than to install ubuntu-server flavour? |
|
[15:58] <rtg> xhaker: you can get the same result using the alternate install and choose 'command line only'. It uses the desktop kernel, but does not install X/ |
|
[16:00] <xhaker> maybe true, but not what a user would expect |
|
[16:00] <xhaker> even and admin |
|
[16:01] <rtg> xhaker: it seems to me to be a matter of RTFM. In any event, the PAE setting for the kernel isn't going to change. |
|
[16:03] <xhaker> rtg: allow me to disagree.. as a user setting up a x86 home server, the server ISO and server kernel seem to be the right choice |
|
[16:04] <JanC> maybe there should be a "home server" edition ;) |
|
[16:04] <xhaker> which cpus boot -server and which cpus don't? should the server ISO install -generic for those cpus? should there be a -server-pae kernel flavor? |
|
[16:05] <xhaker> JanC: ^ |
|
[16:06] <rtg> xhaker: looks guys, this is open source. you are free to develop your own flavour. I've got enough on my plate managing the flavours we do support. |
|
[16:07] <xhaker> rtg: hey man, i agree it's hard to support everything. |
|
[16:08] <xhaker> rtg: but please direct me then to a document that explains what hardware does -server support |
|
[16:09] <soren> xhaker: You have to accept that it's rather ironic that people expect the same kernel images for the *really* big servers, and the tiny, tiny media boxes or whatever. |
|
[16:09] <soren> ...and then -generic for anything in between. |
|
[16:10] <soren> That's hardly sensible. |
|
[16:11] <xhaker> soren: i completely agree with you. that's not what i'm saying. i'm not a debian-installed guy, but couldn't it install -generic for the machines that won't even boot after install? |
|
[16:11] <xhaker> soren: that would fix it. |
|
[16:12] <rtg> xhaker: I'm not sure if there is a doc that describes the HW requirements of the -server flavour. However, it is codified in the kernel config, so you could certainly examine that. |
|
[16:12] <xhaker> s/installed/installer |
|
[16:12] <soren> xhaker: Probably, yeah. |
|
[16:13] <xhaker> rtg: the features page states the -servel kernel is PAE enabled. so yeah, people that know their hardware is not compatible will stay away |
|
[16:13] <rtg> soren: it seems like this issue has come up before for folks attempting to run the lice CD on a 486 CPU. |
|
[16:13] <rtg> s/lice/live/ |
|
[16:14] * soren eeks |
|
[16:16] <xhaker> in the wiki ServerFaq page |
|
[16:16] <xhaker> Do I have to choose the kernel for my system on my own? |
|
[16:16] <xhaker> The installer is capable of recognizing your cpu and install the "best" kernel for it. |
|
[16:18] <xhaker> help.ubuntu.com rather |
|
[16:18] <rtg> xhaker: is the page about dapper server? https://help.ubuntu.com/community/ServerFaq |
|
[16:20] <xhaker> was linked from http://www.ubuntu.com/products/whatisubuntu/serveredition/documentation |
|
[16:22] <xhaker> the system requirement https://help.ubuntu.com/8.04/serverguide/C/preparing-to-install.html#system-requirements |
|
[16:25] <rtg> xhaker: I don't see anything in there that allows you to choose a kernel. |
|
[16:27] <xhaker> rtg: what? |
|
[16:31] <rtg> xhaker: " The installer is capable of recognizing your cpu and install the "best" kernel for it." Isn't that what you were looking for? |
|
[16:32] <xhaker> After seeing that on the dapper ServerFaq, i was searching for something to contradict that on the Hardy documentation |
|
[16:34] <xhaker> did not find any |
|
[16:37] <rtg> xhaker: that looks like a feature that has been removed (at least on the server install). I haven't played with the i386 alternate install, but it closely resembles the Debian installer so the feature may still be there. |
|
[16:38] <xhaker> it's just that i've just wasted 500mb+ of bandwidth, time: downloading, burning, installing. And now i have a non working system. And might have to download the alternate i386 install |
|
[16:39] <xhaker> rtg: does the -server iso ship other images other than -server and -virtual? |
|
[16:40] <rtg> xhaker: not to my knowledge, but I'm not an expert on the installer stuff. |
|
[16:44] <xhaker> https://bugs.edge.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/151942 marked invalid, not reassigned |
|
[16:49] <xhaker> wikipedia to the rescue: PAE is provided by Intel Pentium Pro and above CPUs (including all later Pentium-series processors except the 400 MHz bus versions of the Pentium M), as well as by some compatible processors such as Athlon and later models from AMD. |
|
[16:50] <xhaker> i was affraid celerons would be bit by this too, but it seems they're not |
|
[16:54] <xhaker> let me go try install generic on my server then |
|
[16:54] <xhaker> :D |

[20:28] <psufan> hi we are running ubuntu-server 6.06 lts on some blades hosting vm's and I need to patch against the 2.6.15 nfs crash and burn bug |
|
[20:28] <psufan> what are the standard steps to get the source with buntu's existing config options |
|
[20:29] <psufan> is it still the old patch --verbose < file.patch thing and |
|
[20:29] <alex_joni> psufan: apt-get source linux-image-generic |
|
[20:29] <psufan> how do I compile etc so I can put the image on the other 9 blades |
|
[20:29] <alex_joni> then look in debian/ for ubuntu patches |
|
[20:29] <alex_joni> and put your patch there |
|
[20:29] <psufan> no way just to get the ubuntu sources |
|
[20:29] <alex_joni> the config is also there |
|
[20:29] <psufan> with the existing .config |
|
[20:29] <alex_joni> maybe apt-get install linux-source-'uname -r' |
|
[20:30] <psufan> hmm |
|
[20:30] <psufan> yeah that might be it |
|
[20:32] <psufan> question |
|
[20:33] <psufan> if this http://www.howtoforge.com/kernel_compilation_ubuntu |
|
[20:33] <psufan> is the right way to do it |
|
[20:33] <psufan> how do I ensure it's what is in the existig 2.6.15-57 package |
|
[20:33] <psufan> I wish you guys would have just patched this in 6.06 |
|
[20:34] <psufan> :/ |
|
[20:38] <psufan> err sorry 6.10 |
|
[20:39] <psufan> what is this git stuff |
|
[20:39] <rtg> psufan: start here: https://wiki.ubuntu.com/KernelMaintenance |
|
[20:40] <psufan> yeah yeah I saw the standard party line "blah blah we don't blah" |
|
[20:40] <psufan> oh my bad |
|
[20:40] <psufan> not the same thing this time :) |

[20:41] <psufan> wow this is confusing as hell and I remeber hacking a 1.1.x kernel to run on 1.6 meg of ram |
|
[20:42] <psufan> ugh all I want to do is apply a nfs fix to the existing 2.6.15-51 source |
|
[20:45] <rtg> psufan: your can do it in 3 easy steps: get the source first using 'git clone git://kernel.ubuntu.com/ubuntu/ubuntu-dapper.git ubuntu-dapper' |
|
[20:46] <rtg> install the build tools 'sudo apt-get install linux-kernel-devel devscripts fakeroot libncurses5-dev' |
|
[20:46] <rtg> do the build: 'cd ubuntu-dapper; debuild -b' |
|
[20:49] <psufan> oh shit |
|
[20:49] <psufan> looks like when that pxe boot vm that setup a automated install of ubuntu 6 it screw some stuff up |
|
[20:49] <psufan> apt-get is getting stuff from dapper when it's edgy |
|
[20:49] <psufan> ugh |
|
[20:50] <psufan> nm |
|
[20:50] <psufan> we are using 6.06lts sevrer |
|
[20:50] <psufan> damn you people and you stupid names |
|
[20:50] <psufan> just give me freaking version 1 etc |
