This one is indeed odd and needs investigation. > 2.

The chipset does SATA300 but your disks do not -- they are Barracuda 7200.7 disks, which support SATA150 maximum. However, the motherboard also has a JMicron controller on it. After looking at http://www.farley.org/freebsd/tmp/SATA/dmesg-asus.boot, it's easy to determine that your SATA150 disks are connected to the ICH9 controller (which is being reported at ICH8 for some reason; maybe a chipset ID thing). They are not connected to the JMicron, so the SATA150 limitation here is caused by the disks. The SATA ATAPI errors you see are something I can't really help with, many see these kinds of messages on all sorts of hardware. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
