>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.
