[Bug 290498] Re: linux-rt restricted to one CPU
I have been testing a couple of nights and it happened everytime I had done a Jaunty update. I could pretty well be a motherboard related issue because my suspicion was pointing to the acpid tools. so what I did is : 1. install 9.04 2. install wicd wireless network tool (skip this when you don´t need it) +reboot 3. removal of acpid and dependencies +reboot 4. jaunty update + reboot 5. install of both new ubuntu based RT kernel + reboot: Files for everyone to use (at own risk) can be found at: https://www.yousendit.com/download/MnFqYURNTkw5bEJMWEE9PQ 5. changed audio settings sudo gedit /etc/security/limits.conf at the end of file: @audio - rtprio 99 @audio - memlock unlimted @audio - nice -19 And voila no problem anymore, a perfected running pc. I did a reboot almost after every installation action because I wanted to know if the sound modules were still in working condition after I had done the installs. Again the not shutting down issue and sound getting killed could have been a local issue with my pc, but at least what I can do is share this information with you.

[Bug 290498] Re: linux-rt restricted to one CPU
Vivichrist, The last couple of nights I have been trying to reproduce an Ubuntu Studio 9.04 system with our new RT kernels but I'm dealing with an inconsistent clean jaunty install. The problems I'm having is that sometimes Jaunty does not want to shutdown and after that my sound gets killed. At first I thought that it had to do with the new RT kernels but I am pretty sure that this is not the case because I also saw this problem once after I made a clean Jaunty install and a system update through update manager. What happens is that I get an --apci exiting-- problem when I try to reboot the system, followed by the fact that my sound is gone. Do you also experiencing such problems and if so what is your solution to work around this problem. Would it be better to make a clean install, then install the generic kernel and then install one of the new RT kernels we have been working on? I hope you have some answers/solutions for me.. thanks in advance, Realtime dutchman -- linux-rt restricted to one CPU https://bugs.launchpad.net/bugs/290498 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Vivichrist, I'm back online again and can confirm that my second attempt building the kernel was a succes! I'm running the Ubuntu Studio RT patched generic kernel and realtime behaviour is ok, and don't see any problems.

[Bug 290498] Re: linux-rt restricted to one CPU
Vivichrist, My wireless (SMC card) is working ok. I didn't do a lot of testing though, because it got late yesterday night (it took my system about 3 hrs to build a kernel). Processor time is low and realtime behaviour seems to be fine with Jack/Ardour. What I don't understand is why the Ubuntu Studio team doesn't use the same procedure...because it seems to work very well. Tonight I will test my tutorial once more on another disk to see if it can be made public to everyone who wants to try to compile for him/herself.

Hi Vivichrist, I´m back online with my single core p4 sytem running using the RT patched Ubuntu Studio generic kernel (build from linux- source-2.6.29_2.6.29-02062904_all.deb) like vivichrist did. The system is running smoothly and I don´t notice any problems and had a short test with jack and ardour which turned out to be fine. See jack settings as I reported earlier. My new kernel is called: 2.6.29.4-rt15-all-nvk-052409-1 I did change the .config a little bit though because I switched off kernel debugging in the kernel hacking menu and made the RT settings. I will write a tutorial based on the one I have for the kernel.org based kernel 2.6.29.4-rt15-pentiumpro-nvk-052309-1 . So at leased we have two options now; using the kernel.org based RT kernel or the fully Ubuntu Studio based RT kernel.

[Bug 290498] Re: linux-rt restricted to one CPU
Ok guys here is the deal. If finally managed to reproduce a working jaunty 9.04 kernel, in fact it is running right now while I am writing this update. I found out that Luke macneil´s kernel did not show a splash when studio was booting up and gave me trouble when I wanted to install my wireless. Both Wireless tool wicd and studio's network-manager gave me trouble and killed my sound tools. The only thing I had left was spending some time studying how to build a proper kernel and I think I got it right now. I wrote a tutorial how to build the kernel and tested it three times in a row ending up with the most recent kernel sources from kernel.org (http://www.kernel.org). the kernel I have running on my 32 bit Intel single core (p4) is 2.6.29.4-rt15-pentiumpro-nvk-052309-1. If someone is interested in the installation files (header and image .deb´s) and/or tutorial feel free to send an e-mail realtime.dutchmangmail.com and use the files at your own risk.

[Bug 290498] Re: linux-rt restricted to one CPU
Guys, I have been testing kernel 2.6.29.1-rt8 quite a bit now. This is the home made kernel Luke MacNeil had put on his web site. see download links: http://www.lukemacneil.com/linux-headers-2.6.29.1-rt8-custom_2.6.29.1-rt8-custom-10.00.Custom_i386.deb http://www.lukemacneil.com/linux-image-2.6.29.1-rt8-custom_2.6.29.1-rt8-custom-10.00.Custom_i386.deb Firstly install 9.04 from scratch and after that install both debs by double clicking the files. Ignore the two ¨hmm¨ warnings you will get during installation. Then run update-manager if you want to. Do not use wicd network tool for wireless because it gave trouble in my pc causing it not to shut down properly (acpid exiting problem). I installed the ubuntu network manager instead. I have running it on a my single core P4 and on a dual core pc (Intel E8400) and runs without crashing and audio is handled real time as it should. Jack shows me latencies far below 1 ms . Jack settings: Priority = 89 Frames/Period = 128 Sample Rate = 48000 Periods/Buffer = 3 The rest is default settings. It seems that Luke has managed to build a fast kernel without speed and instability troubles. As far as I understand he has used an old ubuntu kernel configuration to setup his kernel (Hardy? I am not sure). Het took his sources from kernel.org. see web site : http://www.mail-archive.com/ubuntu-studio-us...@lists.ubuntu.com/msg04152.html I hope someone at the Ubuntu Studio team can have a look at the jaunty kernel and compare it with Lukes just to find out what is causing an almost unworkable situation. If i have some time left I will try to duplicate Lukes work and see if I can get the same results with newer kernel versions. I will keep you posted.

Re: [Bug 290498] Re: linux-rt restricted to one CPU
Mike, I installed the official jaunty 9.04 release and don't see any improvements concerning CPU performance. It still is very slow, asking to much time from my cpu and the strange thing is that when I install jaunty on a dual core pc (Intel cpu) it appears to be very unstable but I don't see the delays. Even during installation I had a system hang/crash which resulted in doing the installation all over again. After googling I found out that I'm not the only one having this nasty issue. Last night I gave up using the official ubuntu 2.6.28-3-rt kernel and compiled my own from the www.kernel.org site. I used info from the following web page : https://lists.ubuntu.com/archives/ubuntu-studio-users/2009-May/004757.html and the Debian tutorial how to build a kernel. It took almost three hours before the pc had ended its complie and linking actions but finally I was able to generate to installation deb. files for kernel 2.6.29.3-rt13 which is running on my pc. I still see delays on my single core so that one seems not to be resolved but I hope this kernel will run on our dual core (It should if have read the comments well about this issue).

sorry mentioned wrong version of RT..again..: I also installed Jaunty beta on a single Intel processor machine with 700 Mbyte memory and the installation worked like a champ but... since I need the real time behaviour for studio work I had to modify the menu.lst so that I was able to boot from --linux-rt 2.6.28-3--. So far so good. Everything went wrong when I wanted to work with Jack and Ardour. The processor suddenly needed much more time (DSP indicator in Ardour went sky high) resulting a very slow performing and unworkable daw. It seems to me that the realtime kernel isn't ready yet and since I can not work with the generic kernel (xruns in Jack) I'm forced to switch back to good old Hardy 8.04.
