One thing to be aware of is ia64_vector is u8, which can hold a value from 0-255. NR_IRQS is 1024. So sn_irq_to_vector() will truncate any IRQ > 255. -- Russ Anderson, OS RAS/Partitioning Project Lead SGI - Silicon Graphics Inc [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
