I'm having a similar problem with Ksoftirqd but with other modules perhaps it's related to this problem/bug. The modules in question are CX88_ALSA and CX8800 although i believe it's the later one. I have a constant 20-30% cpu usage from ksoftirqd/0 process only when unloading the CX88_ALSA and CX8800 module the load goes away. But this prevents me from using the tv card in ubuntu.
