It will probably work with UDMA33 mode.  My VIA ata onboard controller 
has a similar problem when being used at any faster mode.  Same drives 
work fine with an ICH controller or at UDMA33 mode.  Cabling is fine also.

BTW, your complaint about my bugfix is unfounded.  By fixing the panic, 
it merely reveals another underlying bug.
