 Hello,
 
 I tried reproducing this within a VMware session on -CURRENT, this
 did not appear to have triggered the problem (mounted /home via
 nfs multiple times, and then unmounted the filesystems one by one
 and nothing went wrong).
 
 What kind of Filesystem are you using?  what is the dump message?
 what is the kernel configuration file?
 
 Please refer to http://www.freebsd.org/doc/en/books/developers-handbook/
 for information on how to obtain a dump which might explain the problem.
 
 Thanks,
 Remko
