    Hello all,

    I noticed the following interrupt storm in my dmesg:

    Interrupt storm detected on "irq11: rl1"; throttling interrupt source
    Interrupt storm detected on "irq5: rl0"; throttling interrupt source

    Here is my vmstat -i:
    interrupt total rate
    irq0: clk 128600 199
    irq1: atkbd0 2499 3
    irq4: sio0 2 0
    irq5: rl0 128901 200
    irq8: rtc 82294 127
    irq11: rl1 128902 200
    irq12: psm0 16152 25
    irq14: ata0 12600 19
    irq15: ata1 71 0
    Total 500021 776

    and here is my dmesg:
    http://cs.ubbcluj.ro/~dan/dmesg.txt

    I have options DEVICE_POLLING and options HZ=200, i have tested with
    greater HZ values like 1000, and without DEVICE_POLLING but i have
    the same storm.
    If you need more info please ask.
    Thanks,
    Dan
