Nope, not without kernel panic information.

Does this machine have serial console?  Are kernel panic dumps being put
into /var/crash?  Is the machine even configured for it (see dumpdev,
dumpdir, and savecore in rc.conf).

It would be useful if you could provide uname -a please, if you're
concerned about the hostname, just XXX it out.  Seeing the kernel build
date is useful.

Please don't do this.  Use ?= for this, not =.  If you think I'm
trolling, please read /usr/share/examples/etc/make.conf.

It almost sounds like a filesystem problem.  You might consider booting
into single-user and running fsck -y.
