Hi, When I do fault isolation on my systems (usually Linux routers at work or my own DAW (digital audio workstation)) I usually start with this, as root: watch cat /proc/interrupts It'll give you a listing of updated interrupts every other second. Use -n for other intervals. Locate the one that gives you most interrupts and go from there. As an example my DAW had serious overload on one USB-port together with other interrupts on CPU0. I moved my mixer to another port (ending up on CPU3) and all's well after that. If you need to you can move interrupts to another cpu-core with help of smp_affinity.
