recent spontaneous reboot on -current and 8 DUP I= in fsck.

[Robert Watson]

I had a spontaneous reboot a few days ago, with a -CURRENT from about a
week ago.  Cause unclear, and I was in X11, which doesn't simplify things.
When it came back up, fsck was displeased with the state of the world:

** /dev/ad0s1e
** Last Mounted on /usr
** Phase 1 - Check Blocks and Sizes
8 DUP I=141
UNEXPECTED SOFT UPDATE INCONSISTENCY

5 DUP I=621
UNEXPECTED SOFT UPDATE INCONSISTENCY
...

** Phase 2 - Check Pathnames
DUP/BAD  I=621  OWNER=rwatson MODE=100644
SIZE=35491 MTIME=Jun 26 14:13 2003 
FILE=/home/rwatson/freebsd/commit/RELENG_4/src/contrib/groff/man/groff_char.man

UNEXPECTED SOFT UPDATE INCONSISTENCY

REMOVE? [yn] y

** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
BAD/DUP FILE I=141  OWNER=rwatson MODE=100444
SIZE=1155 MTIME=Oct 24 19:34 2004 
CLEAR? [yn] n
...

What's odd here is that these files hadn't been touched in a week.  I'm
going to upgrade my notebook to a known source configuration (things a bit
indeterminate here since I had a lot of local patches in odd places) and
see about reproducing.

Has anyone else seen this out of fsck?
