I've reported this at REL 8.2, long ago at May 2011
    https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=156908

Now at 10.1-RELEASE-p10 #0 r282952   i386

This happens, ONLY when first chars are 0 (zeros) in second pair of 8
chars, in which case dumpfs, ommits them.
I.e; For:
    /dev/ufsid/3b9aca0000000001

# dumpfs ada0s1h | head -2
magic   19540119 (UFS2) time    Sun Sep  9 03:46:40 2001
superblock location     65536   id      [ 3b9aca00 1 ]

Problem is in '[ 3b9aca00 1 ]'
