At the point of failure "whatever" produces this SCSI sense data:
    f0 00 01 00 50 40 00 00  00 c2 4f 00 00 1d 00 00 00 00

FreeBSD is wrong to print out 18 bytes because that is an 8
byte (deferred, fixed type) buffer because byte 7 (the
additional length) is 0. Whatever produced that broken
sense data is the probably culprit.

It is trying to say there is "ATA pass-through information
available" but fails to get its message across.
