fsck prevented the box from coming up automatically

/dev/ufs/varlog: PARTIALLY TRUNCATED INODE I=1496123
/dev/ufs/varlog: UNEXPECTED SOFT UPDATE INCONSISTENCY; RUN fsck MANUALLY.
THE FOLLOWING FILE SYSTEM HAD AN UNEXPECTED INCONSISTENCY:
ufs: /dev/ufs/varlog (/var/log)

Anyone seen this before? Any clues?

Please shed some light as to your filesystem and disk setup.
Partitioning details, any GEOM layers you use, you get the idea.
The more verbose the better. Please be sure to state which filesystems
use softupdates and which do not (this matters a lot in this situation).

I forgot to mention -- if the storage disk is physical and isn't
something like a CF card or similar, if you could provide smartctl -a
output from any attached disks (please be sure to state which output
correlates with which disk), I can review that to ensure there isn't an
underlying disk issue.
