If the naming scheme of the interrupts is reasonable, you could use the wild card notation to put probes on a group of functions. You might do a "man stapprobes" to get more information about that. cscope can give you some insight in the the static call tree in the kernel. http://cscope.sourceforge.net/ -Will
