It has nothing to do with the SCSI controller, it's all about the
floppy drive.  It seems like the fdc driver doesn't recognize that
there's no disk in the drive and tries to access it on and on and on. 
As I said, disable the floppy drive in the BIOS (or even put a floppy
into the drive), then the boot process goes on as usual.
