>Description:
As soon as I transfered from 8.0 -> 8.1, ntfs-3g mounted slices, after writting to it, every here and then, kernel panic occurs!

I tried another 8.1 install on clean USB stick..., same thing!

I did upward recursive reinstall of fusefs-ntfs (all ports on which it depends) and nada.
I even did a fresh USB install from zero and same thing occurs.
Sometimes 'cp', causes a panic and sometimes it is a 'vi', the other time it is a 'mv', etc...

Last crash:
-----------
In 'vi' opened file residing at ntfs.
As soon as I've hit: ":w" in order to write changes, panic!

  Panic String: page fault

>How-To-Repeat:
Try to writte to file, which resides on ntfs slice, in txt editor of choice.
I've used 'vi'
