 >Fix:

 There are actually two bugs in two different sections of the kernel.
 Individual fixes for each problem are attched.

   86767-beyond.patch
     fixes main "slice starts beyond end of the disk:..." problem.

     Floppy disks are not expected to contain partition tables.
     See additional documentation within the patch.

   86767-unsupportedUFI.patch
     fixes "umass0: contained Unsupported UFI command 0x35" problem
     also reported in 86767. Originally I thought it was another
     symptom of the same problem.

     USB floppy drives now return "success" on SYNCHRONIZE_CACHE requests

 These patches have been running for some months without causing any
 problems.
