Kernel 2.6.29-RT!!!

Posted: Sat, 02/21/2009 - 22:32
The ticket against the 3.0 release for a 2.6.28-RT kernel has been closed with this comment by Free Included kernel 2.6.29-rc4-rt2 in the master build. According to the tests it seems to behave better than the 2.6.26. I'm closing this ticket for now, and going to release 64 Studio 3.0-beta1 to get some more feedback about this new 2.6.29. That is two parts exiting news... Time to get ready for the beta download! Cheers, Quentin

this kernel is really fast...

...so I would like to continue using it! Here is my story: I was running the standard ubuntu studio 9.04 rt kernel which is known to have issues with firewire, namely full system freezes. So I blindly added the above repositories and installed this kernel. After rebooting this kernel firewire worked, and the latency was very low for audio work. I was very happy until I upgraded to ubuntu studio 9.10. Now this 2.6.29-rt kernel no longer boots at all. While the new 9.10 ubuntu studio kernel is stable with firewire, the performance is significantly worse than this 2.6.29-rt was, in terms of latency, which is now just enough to be annoying. So, I would love to know if there is a way to patch the important parts of this kernel into the one I am now running, somehow? Is this impossible, would I need to switch fully to the 64 studio distribution? I know it is kind of a strange place for this question, sorry but where is better?!

Hi eric71, Yes I believe that's the the latest kernel and very interesting that installing the .deb worked when apt-get is failing on so many installs. You are right, mixing repo's is not recommended but I also like the kde desktop and mepis using 64studio repo's worked fine with 2.1. I'm enjoying kde 4 here on one of my beta installs. kde 4 is light and works well as a studio desktop as long as you just install the basic core. You should have the 64studio package installed so as to keep the studio balanced. Cheers! Dave.

beta2 & beta3 kernels

Hi eric71, The errors you have been getting are the ones reported on the mailing lists & here on the forum. They are strange and I'm still not sure of the reason. The beta2 kernel is configured at 250hz and the beta3 at 1000hz, maybe this has something to do with the errors? Free no doubt will address this error in time for the 3.0 final release. Interesting to see you use mepis with 64studio kernel as I always have the same setup installed here. Mepis is a fine distribution. I haven't tried with mepis 8 yet but I will give it a go after reading your post. Is it the 1000hz kernel you have used? Cheers! Dave.

I will have to check, but I'm pretty sure it is the 1000hz. It is the most recent one here http://apt.64studio.com/backports/pool/main/l/linux-2.6/linux-image-2.6.29-1-multimedia-686_2.6.29-2_i386.deb It might be of interest that in Mepis 8 I have just been downloading this deb directly and installing it (KPackage by default in Mepis, no Gdebi there), rather than adding the repositories and using Synaptic as I did with the *buntus. Could be there were errors and I just didn't notice them because I didn't have Synaptic making it obvious for me. At any rate, I've been increasingly becoming a KDE man (3.5.10, anyway), and as long as it is working in Mepis, I might stick with it. I may add the 64 studio repositories to Mepis, as i'd like to run the latest jack as well, and just trying the jackd package leads to dependancy issues - so it's not just a one file download and install like the kernel image. That might be asking for trouble elswhere, though, really mixing up Lenny and Hardy things.

Odd error on install

I have tried to install the 2.6.29-multimedia kernel image on both fresh fully updated hardy ubuntu and kubuntu 8.04.2 installs. In both cases Synaptic complained toward the end of installation something along the lines of "error exit status 128" and that it couldn't be configured. The kernel didn't show up in Grub. With the Kubuntu install, I updated grub and was able to boot the kernel, and it worked, aside from a few odd things - such as the IPW2200 driver not working, as if it didn't see the firmware. Installing a Debian Lenny IPW2200 firmware package repaired this. But it was all kind of odd. i'm sure it has to do with the kernel-image package not being configured. This is odd, because I have been using this 64 Studio kernel in Mepis 8 which is Lenny based, and it is working just fine, with no issues when installing. I figured I would install Hardy, as the kernel was compiled specifically for it. I know I should be working from the 64 Studio iso's, but I do not have a dvd burner. I suspect other people will be trying to upgrade to 64 Studio via hardy installs and might encounter the same problem. Any possible reasons for this error?

is there a way to get this

is there a way to get this rt-kernel in a 3.0-installation made by dist-upgrade with lenny enabeled in the sources list?

Hi 64studio packages upgrade & kernel tests. $ dpkg -s 64studio $ apt-cache policy 64studio 64studio: Installed: 3.0~pre7~hardy1 Candidate: 3.0~pre9~hardy1 Version table: 3.0~pre9~hardy1 0 500 http://apt.64studio.com hardy-backports/main Packages 3.0~pre7~hardy1 0 100 /var/lib/dpkg/status Packages are installed. Used: 2.6.26-1-multimedia-686 (rm 2.6.28-rt & 2.6.29-rt kernels) build kernel with one change = 1000hz $ sudo dpkg -i 2.6.29-rc4-rt2 build-2 1000hz High resolution type of feeling, audio seems better, desktop very energetic. 64studio installer is improving, The system settled here. The Menu choice is improving, packages improved. On second day with 1000Hz kernel. The 64studio packages are doing there job well, stability is vital, testing is not for everybody, it was tempting to make other changes. The test was 1000hz, the aim, 3.0 released stable. Cheers! dave

The beta is not package complete!

angelsguitar, The beta is not feature complete. Quentin said that we should start seeing a release with all packages included when Free releases the RC. Not sure when that will be but hopefully soon!! tb

OK, perfect then. I'll wait

Hi. I noticed that the 2.6.29 kernel in beta 2 is compiled at 250Hz instead of 1000Hz. I don't know if this was done of purpose for testing reasons, but just wanted to point that out, just in case. Running the kernel at 250 Hz is low for MIDI applications like Rosegarden, which depend on a clocking source for syncronization. By the way, I noticed that Rosegarden is not included in 64 Studio 3.0...

This is a known issue, and has been reported to Free over the weekend. I suspect it will be solved soon.

Hi Quentin, It's great news. It will be fantastic to get all the users on board who had problems with the old kernel & hardware issues. "coldduck-unmastered.wav" is well and truly etched in my mind now. Something like your "As Vrede My Pad-demo.mp3" would have been very peaceful to work along with. It sounds great on my system here and I bet it was a satisfying project to work on. I've got a sweet spot for acoustic sounds, maybe that's because I play acoustic guitar. Its a shame 64studio doesn't have some samples on the server we could all download, I'm sure it would help to have community samples/midi files etc., to help us to learn how to use 64studio software. Maybe you have some more of your recorded work available. I for one would like to hear it. To jump from 2.6.21 to 2.6.29-rc4-rt2 is quite a leap. 2.6.26 had reports of issues, but I have to say, it works ok here. I suppose someone/somewhere is always going to have problems with any kernel. The git clone 2.6.28, well you gotta luv the git tool, but the kernels behavior doesn't seem to have the edge the patched 2.6.29 does and vga kernel options when booting causes problems with qjackctl%. Another build of the git clone 2.6.28 is something I want to do again very soon. I'm looking forward to the feedback on the 64 Studio 3.0-beta1 release, but the bit I like best is that users who had problems with 3.0 alpha/2.6.21/hardware issues will finally get on board the testing for the 3.0 final. It's great the way GNU/Linux is always on the move and growing. It's very exiting and a refreshing feeling to know just what is possible within a community focused on an end goal. Cheers! dave.

Fails with linux-kbuild message

Hi Contrary to what some others have to say on the matter, I love the idea of 64 studio on top of an ubuntu base! What I did was to install a plain hardy and add the 64 studio repositories and upgrade and add the packages named 64studio. eeverything seems to be working on two computers. Anyway - what I was trying to do was to instal the kernel 2.6.29-1-multimedia, but the headers refuses to. It gives me an error saying that it is dependant on linux-kbuild-2.6.29 which is not available. Any takers? Best regards Ketil Thorgersen
