This is kinda frustrating, as the CPU load seems rather low (< 15% when the xrun happened). I guess I'll test out reiserfs and even ext2 to see if the filesystem is the culprit. I turn off just about everything that's not related to the recording process, including NTP, xscreensaver and a few other things. In addition, I run FluxBox (a lightweight WM) rather than either a GNOME or KDE desktop. I've also done a lot of work with hdparm to tune the hard drives, and mount both /tmp and /var/lib/jack/tmp as tmpfs partitions, which helped a LOT. Oh, and I use reiserfs on the partitions that I record to. You definitely want to use a journaling filesystem for critical data like this, and though there's quite a bit of debate on which is better for audio recording, reiserfs has performed like a champ for me. I haven't had an xrun during recording for quite a long time now on a 1GHz P3 system with 512MB of RAM, making me a happy guy.
