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:

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
