Problems with 2.6.18 and SATA DVD-RW Toshiba SH-W163A

[Johannes Resch <jr@xor.at>]

Hi,

I'm trying to get a Toshiba SH-W163A CD/DVD-RW SATA drive working with 
linux.

Both running 2.6.17.7 and 2.6.18 gave me some issues. However, in 
2.6.17.7, the drive was usable for reading CDs/DVDs (logging lots of 
"BUG: warning at drivers/scsi/libata-scsi.c:823/__ata_eh_qc_complete()" 
syslog entries, though).

In 2.6.18 it seems the drive is not working at all, and the boot process
takes ~1 minute longer due to speed probing on the SATA port.

Below is kernel output from both 2.6.17.7 and 2.6.18.
System is Athlon XP on a Via KT600 mainboard (Asus A7V600).

Any suggestions what may be wrong here?
I've verified with another OS that the device itself is working - so it 
should not be a hardware/cabling issue.

regards,
-jr
