(For the curious, the reason ZFS triggers this when UFS doesn't is 
because ZFS sends a synchronize cache command to the disk, which is not 
handled in DMA mode by the controller; and for this particular 
controller, switching between DMA and PIO mode has some quirks which 
were worked around by adding delays. The fix involves a new 
quirk-work-around.)
