ATA identify retries exceeded (still!)

[Fierman]

hello,
I am driven almost insane by this ATA driver problem on a mini-atx
machine. (device being a liteon DVD player):

ata0-slave: ATA identify retries exceeded


5.1, but also happened in 4.7 as well as 4.8.
I am aware that it was a well known problem, but it appeared to be fixed
from early this year on.

The odd thing is that (ofcourse) the problem is rather hard to
reproduce, sometimes the DVD wont get recognized for 10 boots in a row,
sometimes it works perfect.

possible solutions tried:
- other IDE cable
- other DVD player
- hw.ata.atapi_dma to "0" or "1" in /boot/loader.conf
- hw.ata.ata_dma to "0" or "1" in /boot/loader.conf
- the odd bios fiddling

all to no avail.
is anyone still having the same problem with newer kernels?

does anyone know of a solution?


thanx in advance, Fierman
