It's not really a problem, as the device and the SATA hard drives and DVD+RW attached to the bus operate properly, but I'm wondering why the ICH9 controller (in AHCI mode) on the Asus P5K-E motherboard shows up as:
atapci1: <Intel AHCI controller> port 0xac00-0xac07,0xa880-0xa883,0xa800-0xa807,0xa480-0xa483,0xa400-0xa41f mem 0xfbffe800-0xfbffefff irq 22 at device 31.2 on pci0
Because your motherboard allows for the enabling of AHCI on the ICH9. This is often a BIOS feature you can turn on/off.
Just wondering why it is not properly detecting this as ICH9. Again, just something cosmetic that I'm curious about. I'm going to double check the BIOS settings now, but I am confident I have them set as AHCI in the BIOS. I suppose this could be a BIOS bug of some sort. I can also try upgrading to the latest BIOS.
I don't believe it's a bug. FreeBSD has a form of "generic AHCI" support, where for systems which indicate AHCI is available but has no direct AHCI chipset driver, will fall back to using a generic AHCI implementation that should work with most all AHCI implementations.
I would say what you're seeing is good. AHCI == good.
