Ignore the irq# for > soft intrs. JFYI: vectors are not the same as hard interrupt numbers. On ia64 they imply priority, which means that vector numbers should be selected for their priority and not have a 1-to-1 mapping with IRQ number. On powerpc they mean absolutely nothing other than being an index into an array. It's better to use IRQs and not vectors to lookup int. events by number. FYI, -- Marcel Moolenaar xcllnt@mac.com
