I don't know for sure. Seems that slamming the CPU to 100% busy makes the messages occur much less. Yikes! Look at this: # vmstat -i interrupt total rate irq0: clk 8299985 116 irq1: atkbd0 67 0 irq4: sio0 5325 0 irq8: rtc 1065804 14 irq11: re0 73060 1 irq14: ata0 15 0 irq15: ata1 58 0 Total 9444314 132 Maybe acpi will help that too.
