>Description:
I have experienced a freeze when trying to "mv some_file" from an NTFS
partition to my home directory. It happens both with my custom kernel
and with GENERIC.

It prints out the error message and after that any action which
requires hard disk access just hangs.
>How-To-Repeat:
'mv file' from a rw-mounted NTFS partition to any FreeBSD directory.
>Fix:
Mount any NTFS partition read-only.

 Please configure DDB according to the instructions in the developers
 handbook, as well as INVARIANTS, INVARIANT_SUPPORT, DEBUG_VFS_LOCKS,
 WITNESS and DEBUG_LOCKS in your kernel.  Then run the following DDB
 commands when the system hangs:
 
 show lockedvnods
 
 ps
 
 alltrace (or at least 'trace <pid>' for each value of <pid> listed in
 show lockedvnods)
 
 and provide the resulting output (screen capture/serial console
 log/etc).
