    The only thing that has changed recently is the aic7xxx driver, but
    I find it hard to believe that it would suddenly report media errors
    (a status indication returned from the drive) because of these changes.
    Why not boot the old kernel and see if your problem still occurs?  I
    think your drive needs to have its heads cleaned or to be sent in for
    service.
 
 We've cleaned the drive repeatedly, to no effect.  We would love to boot
 the old kernel, but (guess what?) it's on tape.  ;-)
