Anyways, i reuploaded the tarball. The program tries to detect missed irq's now and counts the total number of irq's delivered by /dev/rtc. Since the program does not recover from missed irq's the "statistical" data for these runs is useless [except for the knowledge of the fact that one or more irq was missed :)] flo - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
