This is with the 1.218 change backed out. # vmstat -i interrupt total rate irq0: clk 82734023 1000 irq4: sio0 2 0 irq6: fdc0 10 0 irq16: fxp1 10347 0 irq17: fxp0 29339 0 irq19: ahc0 187220 2 lapic0: timer 165447117 2000 lapic1: timer 165430135 1999 Total 413838193 5002 I'll check the battery and step it back down to 366Mhz (now at 510). -- Pawel
