Hello,

        Here is a 'little' problem with vm_zone structure and field
'zname' in it.

        zinit() function takes a pointer to name of zone and assigns it to
field zname. Since nfs module defines this name in the static module
memory pointer to name becomes invalid when module unloaded via kldunload 
command. This will lead to trap in kernel or will produce junk in sysctl
output:

        # kldload nfs
        # kldunload nfs
        # sysctl vm.zone

        Last command will produce panic. This has been reported as
PR-kern/12464
