No.
vmstat -i with ACPI enabled:
interrupt total rate
irq0: clk 93354 993
irq1: atkbd0 440 4
irq8: rtc 11948 127
irq14: ata0 2193 23
irq15: ata1 59 0
Total 107994 1148
vmstat -i without ACPI:
interrupt total rate
irq0: clk 31530 985
irq1: atkbd0 187 5
irq8: rtc 4036 126
irq9: de0 7 0
irq14: ata0 2042 63
irq15: ata1 59 1
Total 37861 1183
