Software Environment:

Vanilla kernel 2.6.24

Problem Description:

The ASUS DVD-E616A DVD-ROM drive is capable of doing UDMA100. In the configuration above it is configured for cable-select and connected to the mainboard PATA controller via an 80-wire cable together with a Panasonic SW-9576. This configuration works fine on other operating systems, e. g. BSD.

The 80-wire detection for this drive fails on Linux with this message:

hdd: ASUS DVD-E616A, ATAPI CD/DVD-ROM drive
hdd: host max PIO5 wanted PIO255(auto-tune) selected PIO4
hdd: drive side 80-wire cable detection failed, limiting max speed to UDMA33
hdd: UDMA/33 mode selected

This happens regardless wether it is connected at the end of the cable, in the middle, configured as master/slave etc., while the 80-wire detection for the other DVD drive (Panasonic SW-9576) on the same cable succeeds. Even if the DVD-E616A is connected alone as single drive, the detection fails.
