Seeing this too on Hardy (hasn't the fix ever been backported?); a sudden flurry of coasters from a DVD recorder (still writing CDs without issue) that had worked well under Feisty (and XP, sigh) took me here.
To my surprise (as for everyone else in this thread, contrary to the dmesg output below), what I found inside the box was an 80-pin connection for both adapters. In my understanding, the legacy LS-120 (high-capacity floppy disk drive) should not cause the whole bus to be slowed down either - nor should the DVD recorder have any problems even at UDMA/33 even if this actually were "just" a 40-pin cable.
