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)
ata4.00: ATAPI: PIONEER DVD-RW  DVR-212, 1.21, max UDMA/66
ata4.00: qc timeout (cmd 0xef)

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.
