Mmmh, maybe just renice asterisk processes giving them highest priority can help you. If it doesn't make sure SMP support is been compiled in kernel and process usage is fair between the twos CPUs.

I running Asterisk(PBX) application on that. When we try to open any other application(like mozilla,lock screen,opeoffice...) while Asterisk was up and running with huge dialouts the signaling link was geeting down (i.e missing interrupts). How can over come above problem by modification at kernel level(tuning the kernel) Any appreciated!
