Hello,<br><br>I've spent a couple of days trying to sort out my problem, so far with no luck. I hope one or more of you has the answer. I've looked through the PlanetCCRMA mailing list archive, and I see clues, but not enough information for me to go on. Here is my problem. <br>
<br>I have a focusrite Saffire Pro 26 IO firewire interface. I was using the PlanetCCRMA distro with Fedora Core 10, and an updated linux kernel 2.6.29 (can't remember the rest, but it was from the planetccrma testing repository. ffado, jack, and ardour all worked well enough, with a few glitches and lockups and xruns, etc. But it was useable. I spent some time trying to get the focusrite midi interface working, without success. So I tried upgrading to the Fedora 12 distro, with planetccrma. Nothing worked, and I couldn't get the my nvidia video card working under the new realtime kernel (2.6.31). ffado wouldn't load and the ffado diagnostic software said that I had the new firewire stack built into the kernel and that ffado 2.0.0.x didn't work with that stack. Okay, now what? I thought I'd get brave and try the beta of Fedora 13. I had heard that the new 2.6.33 kernel might work better. But now I find out there is no realtime kernel that new (unless I try to compile it myself with the realtime patch). And ffado still gives me the same message (I'm using the stock Fedora 13 kernel, without the realtime patches). I had heard that the new kernels are pretty fast and that maybe I wouldn't need the realtime patch. I tried downloading the latest ffado versions, even the SVN development package, but on the stock Fedora kernels, it complains about the in-kernel firewire stack being incompatible with ffado (but it doesn't offer any help as to how I might remove the firewire stack from the kernel. I've read about blacklisting stuff in 'modprobe.conf' but am not sure if that would help). <br>
<br>I'm in a dilemma, and don't quite know what to do. I COULD go back to Fedora 10 and use the 2.6.29 realtime kernel, and try to figure out how to get midi working. The nvidia video driver compiles on that kernel (I haven't figured out how to make it compile on the newer realtime kernels (there have been some changes in the kernel and the nvidia driver needs patches to make it compile and run with the 2.6.31 kernels). <br>
<br>I could also reload Fedora 12 and try again with the Planetccrma realtime kernels. I just thought it would be interesting to try Fedora 13 and see if the newer 2.6.33 kernels might work better with ffado and jack. <br>
<br>Or I could revert back to the (now unsupported) Fedora 10 and Planetccrma. Then there is Fedora 11 and Planetccrma... Oy! <br><br>Here's what I'd LIKE to do: find a step-by-step set of instructions for getting ffado to work on the newer realtime kernels (yes, I've looked at the ffado web site and sent a message to their mailing list but so far no response). I believe that involves getting a kernel with the new in-kernel firewire stack removed. <br>
<br>One thing I haven't tried yet is installing one of the Fedora 12 realtime kernels on Fedora 13 just to see if it makes ffado any happier. I'll try that next and report back on the outcome. Failing that, I'll try re-installing Fedora 12, then try Fedora 11, than revert back to Fedora 10, which worked well enough once I installed realtime kernel 2.6.29x. <br>
<br>I apologize if I'm missing something technical here; I've worked with Linux since 1994, and have spent a lot of time in the past learning how to make stuff work (by googling and reading and studying and asking questions). Lately, however, I've been just wanting to make music, and not fight with the technology. So I've been reluctant to go through the rigamarole of getting up to speed technically to the point where I can recompile the kernel if necessary (for example) to solve a problem. I just want to get back to recording! <br>
<br>Any suggestions and/or advice would be much appreciated. I need to move on this pretty quickly as I have customers who want to record some music, and right now I have a broken system. <br><br>Cheers,<br><br>John<br>
