I have managed to get my SATA DVD drive working by moving it to another
SATA port on my motherboard. I have no idea why this worked, but I
no-longer get the "xfermode" error on boot, and the drive just works.
If you are troubleshooting the same problem, I would strongly recommend
trying all of your SATA ports before anything else.

I recently bought a SATA Pioneer DVR-212D drive and fitted it to my
(64 bit) Fedora 7 system. On boot I get the following error (it also
appears when dmesg is run):
ata4.00: failed to set xfermode (err_mask=0x4)
The full dmesg output for ata4 is at the bottom of this post.
I have Googled the problem and found plenty of references to it, but
nothing that sounds like a solution. Especially for F7.
Can anyone shed any light on this problem for me? System specs:
- CPU: Intel Core 2 Duo e6600
- Motherboard: Gigabyte GA-965P-DQ6
- Kernel 2.6.22.1.3225.fc7.x86_64
dmesg output for ata4:
ata4: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

Further info on this problem:
I came across this post:
http://fak3r.com/2007/06/22/failed-to-set-xfermode-solved/
Regarding the same/similar problem on Ubuntu and a solution for it. I
have tried this solution with no luck. I added "irqpoll" as instructed
in grub.conf:
title Fedora (2.6.22.1-41.fc7)
root (hd0,0)
kernel /vmlinuz-2.6.22.1-41.fc7 ro root=LABEL=/ rhgb quiet irqpoll
initrd /initrd-2.6.22.1-41.fc7.img
But no luck. I still get the same error on boot and the DVD drive is
not accessible.
