>Description:
FreeBSD hangs and reboots if one do some operations (a copy of files)
with a NTFS partition mounted in the filesystem tree.
The NTFS partition is on a SCSI disc (ID=0) and FreeBSD is on an IDE disc (dual boot configuration) set as master on first IDE channel (i.e. on disc "c:")
>How-To-Repeat:
To reproduce the problem try the following:
1) mount (read only) a NTFS 4 partition and copy two (or more)
BIG files from NTFS partition to the FreeBSD partition (I copied two 70M files).

2) WHILE the copy is "in progress" type a simple ls -R / on a different terminal.
On my system this ALWAYS produces a hung and next a reboot.

For example:

# mount -t ntfs -r /dev/da0s1 /ntfs

$ cd /home/trust<---------------------this on terminal 1
$ cp /ntfs/TEMP/bigfile ./bigfile1 <--this on terminal 1
$ cp /ntfs/TEMP/bigfile ./bigfile2 <--this on terminal 2
$ ls -R /  <--------------------------this on terminal 3

The last 3 commands MUST be executed at the same time to
reproduce the bug.

>Fix:
I don't know,... the only thing I can do is to NOT overload the system during the copy.
