Binary package hint: linux-source-2.6.20
Following update to latest Feisty kernel (2.6.20-8) my root partition fails to mount during boot. Kernel 2.6.20-6 works, noacpi does not help. Root is an ext3 partition on sda2. SATA harddrive is plugged into port 1 of i965 controller on an ASUS P5B VM.
I presume the relevant section of the boot log is:

Attached are kernel boot log, lspci output & hdparm -I output.
I have the very same modprobe crash but with a Gigabyte 965P DS4 mainboard, which has the same Intel 965 chipset as your Asus mainboard.
I don't have any SATA hard discs connected, the only SATA device here is a SATA DVD burner. My harddiscs are IDE drives which are connected to the motherboards JMicron 20360/20363 AHCI Controller (AHCI is turned off, it runs in IDE mode).
The last working kernel here is linux-image-
