This is almost certainly a duplicate of bug 891665 reported to nfs-maint. Here is more explanation from that previos bug report. "After adding nsf4 export strings to /etc/exports for the first time (nfs hasn't run on this machine since upgrading from Fedora 16), then running service nfs start, the system crashed. Don't know if is was because I used service instead of syscemctl."
