It will be a good idea if you use oprofile or built-in profiling feature
inside Linux kernel to find the hotspot. Then, based on the result,
together we can find the root of the trouble. Also, please provide
kernel version (+ patches, if any) you currently use.
Just a guess, maybe recently someone is increasing the number of softirq
being processed inside interrupt handler path. So instead of passing
them to ksoftirqd, more and more softirq is processed in the handler.
