Have you tried the nodma option?  I have read that it works for many.

Something I found on the weekend while installing FC4 on my laptop is 
that some bioses setup sata devices as legacy devices and this can 
cause weird problems.  This the issue on my laptop that prevents me 
from using dma for the drives.  I have to wait for either a bios 
upgrade or a better Linux driver.  I guess no playing of DVD's right now.
