    IRQ 0 and 8 are clock interrupts (1/HZ for the scheduler, and a RTC),
    and IRQ 2 has some odd aggregate or multiplexing function for
    historical reasons; none of these make a good choice as an entropy
    source.

    Using an IRQ for your NIC (10?) and/or an interrupt for your hard drive
    (14?) are much better.
