>I briefly tested the latest mainline kernel (3.6.3-1 as of this writing). I don't see this issue with 3.6.3-1. I ran some quick tests on various kernels by booting and running 6 cpuburn threads for 10 minutes. Here is the cpu time of the ksoftirqd processes and the output of /proc/interrupts for the following kernels:
