So from what the other submitters reported, it sounds like this is
the result of paralellism in the rcS scripts.  This would imply
that there's a missing dependency relating to checkroot.sh.  So
this should be fairly simple to fix once we know what's running
in parallel inappropriately.

/usr/share/insserv/make-testsuite and
/etc/init.d/.depend.boot
will show you the dependency graph.

Looking at the screenshot you attached, I can't see any obvious
reason for fsck to make the kernel panic.  There's no indication
of odd scripts (other than geli) running in parallel here.  This
really needs investigation from a kfreebsd person; I'm not
sufficiently knowledgeable to look into it myself.

Roger
