 From your previous post:

"I can get FC2 (kernel 2.6.5-1.358smp) to boot by mounting the initrd; 
editing linuxrc to load the mod_scsi, libata, sd_mod & ata_piix modules 
on boot; and then unmounting and replacing the original initrd.  This is 
OK in that it works however from about kernel 2.4.24 it was unnecessary; 
the sata drive showed as "hde" and performance was many times better. "

Since no one else has replied, I will give this a shot. With the 2.4 
kernel, you were using the PATA driver for the SATA. Since you have 
loaded libata, you are using the new PATA driver with the 2.6 kernel. I 
am not sure which SATA chipset your motherboard is using (GigaByte web 
site is unclear), so you might want to look at:

    http://seclists.org/lists/linux-kernel/2004/May/1809.html

and see the status. libata is still new, and supports some chipsets 
better than others. Could be libata is having problems with your 
chipset? Might also be a setting in your bios.

Maybe you could not load libata and ata_piix on your next boot, and see 
if you can get better performance using the PATA driver.
