I'm writing back on my AMD_64 here. It's certainly stable and doesn't crash. I can forward a 2.6.15-rt18 .config file to someone. (Carmen? email address please. Florian? Drop me a note if you want a copy.) One note: Based on a comment Lee Revel made a few days ago, I think on this list, about the standard kernel giving good realtime results I built 2.6.16-gentoo-r2 on Saturday. It's now up two days with no problems. I'm running at 128/2, and even 64/2 as shown below) in Jack with no xruns so far although I've got a cold and am using it very lightly right now. Anyway, I agree with Lee (so far!) that even the current 2.6.16 series is giving much better performance than older kernels even without Ingo's patches. IF it matters I use the realtime-lsm module and not the othe PAM based stuff. mark@lightning ~ $ uname -a Linux lightning 2.6.16-gentoo-r2 #1 PREEMPT Fri Apr 14 19:18:44 PDT 2006 x86_64 AMD Athlon(tm) 64 Processor 3000+ GNU/Linux mark@lightning ~ $ 03:39:46.194 /usr/bin/jackd -R -P80 -p512 -dalsa -dhw:1 -r44100 -p64 -n2 03:39:46.209 JACK was started with PID=6939 (0x1b1b). jackd 0.100.7 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. loading driver .. apparent rate = 44100 creating alsa driver ... hw:1|hw:1|64|2|44100|0|0|nomon|swmeter|-|32bit control device hw:1 configuring for 44100Hz, period = 64 frames, buffer = 2 periods nperiods = 2 for capture nperiods = 2 for playback 03:39:48.278 Server configuration saved to "/home/mark/.jackdrc". 03:39:48.279 Statistics reset. 03:39:48.337 Client activated. 03:39:48.338 Audio connection change. 03:39:48.342 Audio connection graph change. 03:42:16.866 MIDI connection graph change. 03:42:16.924 Audio connection graph change. 03:42:29.945 Audio connection graph change. 03:42:29.963 Audio connection graph change. 03:42:32.372 Audio connection graph change. 03:42:33.834 Audio connection graph change. 03:42:34.943 MIDI connection graph change.
