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.....
