FC2 is what i use. However... you'll end up using the siimage IDE 
driver rather than the sata_sil libata driver, unless you recompile 
the FC2 kernel and either leave siimage out or build it as module. 
I've no idea how reliable siimage is, as I was intent on using 
sata_sil, but a very quick experiment using hdparm with siimage 
managed to cause grief (system hang iirc), so that's one bit of 
evidence to suggest siimage isnt..

grep kernel /var/log/messages - any sata/ide/sdX errors in there?

what kind of disk? Is it one of the blacklisted disks?
