I believe I have solved the panics with the NTFS filesystem by porting
the NetBSD lockmgr -> mutex locking changes to our NTFS filesystem
implementation.

The locking changes are available in PR 120483

 http://www.freebsd.org/cgi/query-pr.cgi?pr=120483

I have also submitted a style change PR which will allow us to easily
compare the NetBSD implementation to our NTFS implementation in PR
120482:

After the locking patch and style patch have been applied, all that is
left is to review the remaining changes between the FreeBSD and NetBSD
NTFS code to see if we should port additional fixes from NetBSD.
