Does this happen if you disable ACPI at boot?

If you are using UFS2, by default if the filesystems were not cleanly
unmounted, the machine would run fsck_ufs at boot.  You would notice
this happen because (normally) it would cause lag on the machine.

If the filesystem is already unmounted, no.  It cannot write to
/var/log/messages at this point.
