If you boot the machine in single-user, and run fsck manually, are there
any errors?
Only thing I can think of off the top of my head: there's a known
situation (also applies to RELENG_7) where a background fsck doesn't
correct all errors after a system crash/unclean shutdown. I mention
this because I see "softdep" in the above stack trace (usually refers
to
softupdates). I don't know if this got fixed, but the workaround is to
use background_fsck="no" in rc.conf. Yes, after a crash this means
you
have to wait for the entire fsck to run.
I can point you to some (old) discussions about it if need be.
