Hi: I have a freebsd 7 on a MSI k9n6g motherboard based on Nvidia MCP61. The problem is if i connect a second hard drive to the sata controller online, i got 89% of my CPU used by interrupt (systat -pigs shows irq20: ata). The drive works but ate all my CPU. If i start it with the drive plugged works like a charm. Any ideas -- mmm, interesante.....
