Hi,<br>I've been trying to run Ardour 2.7.1 with jackd 0.116.1 with a Mackie Onyx 1640 with the firewire expansion. I have a Dell Studio desktop, Core 2 quad 2.33, 6gigs DDR2. I was running the same setup on 8.10 with only minor problems. I get xruns, jackd crashes, ardour crashes with the vanila kernel, and most recently my entire computer becomes unresponsive with the real time kernel. Also system monitor says I only have 3.1Gib of ram and 3.1Gib of swap. Memtest and my bios both say I have the correct 6gigs of ram. I have modified limits.conf for realtime priority and memlock. I have tried every setting I can think of for the freebob driver and the "firewire" or FFADO driver . No matter what I get either xruns, crashes of lockups. I know that the rt kernel didn't support multiple processors in 9.04 for some time but from what I understand thats been fixed. Does anyone have any insight to my instability problems? Do I need to go back to 8.10? I haven't been able to duplicate the crashes as they seem unpredictable. I can sometimes get it to crash by scrolling/resizing. Maybe its the video chipset, I have the intel GMA 4500HD chipset.<br>
