I have an IHC controller on my Toshiba Laptop.  There was a kernel 
change some time ago that allowed my laptop to work with DVD's and speed 
up the speed of access.  There are two areas to check.

The BIOS may be trying to run the SATA drives as IDE drives.  There is 
also a flag for the kernel that will enable DMA for the SATA drives. 
The laptop is at home but I am at work.  I sent the info home and this 
was one of the settings I changed.

libata.atapi_enabled=1 in the modprobe.conf file
