The process ksoftirqd/0 uses permanent 15% CPU on our debian squeeze server.

4 root      20   0     0    0    0 R 15.0  0.0 850:59.17 ksoftirqd/0   

I already read that this can have various reason like Full harddisk or high network traffic. In our case we do have more or less low network traffic and enough space on hard disk. How can I analyse what causes ksoftirqd/0 to use permanently 15% CPU?
