>Description:
I get this error when using an 80 wire udma66/100/133 cable
to connect a maxtor harddrive. I verified this config as working
in a normal pc, in the promise controller screen ( udma6 ).
It looks like the driver doesnt do the correct udma133 initialization on alpha.

Switching to an udma33 cable sped things up quite a bit.

>How-To-Repeat:
Use a promise udma 133 controller with the supplied cable and a udma133 drive in an alpha.
