Comment 0 for bug 95383

I'm trying to install kubuntu feisty beta (i tried both the desktop and alternate i386) but the installer, and i think the kernel too, can't find my sata disk (i tried to "fdisk /dev/sda" but it replied "unable to open /dev/sda)

my motherboard is an "asrock 939-Dual sata II"
 this is the output of lspci (i hope will help to find the problem)
