ata2 problems on boot

[remigio <realelino@tiscali.it>]

Hi,
I've installed Debian Etch and there is this problem:
system starts and during boot it pauses for at least one minute trying
to setting an "ata2" device.

Dmesg shows:

ata2.00: qc timeout (cmd 0xa1)
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata2.00: revalidation failed (errno=-5)
ata2.00: limiting speed to UDMA/25
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: qc timeout (cmd 0xa1)
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata2.00: revalidation failed (errno=-5)
ata2: failed to recover some devices, retrying in 5 secs
ata2.00: qc timeout (cmd 0xa1)
ata2.00: failed to IDENTIFY (I/O error, err_mask=0x4)
ata2.00: revalidation failed (errno=-5)
ata2.00: disabled
ata2: failed to recover some devices, retrying in 5 secs
ATA: abnormal status 0x58 on port 0x177
ata2.01: failed to IDENTIFY (I/O error, err_mask=0x40)
ata2.01: revalidation failed (errno=-5)
ata2: failed to recover some devices, retrying in 5 secs
ata2.01: configured for UDMA/33
  Vendor: HL-DT-ST  Model: DVD-ROM GDR8162B  Rev: 0015
  Type:   CD-ROM                             ANSI SCSI revision: 05

If on BIOS I set only the SATA controller active (without PATA) the
system starts endured but Debian don't tecognize cdrom and dvdrom.
The problem has been marked also like bug in the system of tracking of
Debian with the number Bug#402533, but it seems there are no solutions
yet.
Have you some suggestions to solve this problem?
Thank you very much.

Remigio
