>Description:
Useing a program called:

http://sourceforge.net/project/showfiles.php?group_id=46038&package_id=44988&release_id=84491
Fatback v1.3
(c) 2000-2001 DoD Computer Forensics Lab

fatback: ELF 32-bit LSB executable, Intel 80386, version 1 (FreeBSD), for FreeBSD 5.0.2, statically linked, stripped

Useing fatback on a flashcard reader with a 2GB flashcard on FreeBSD 6.0/i386 causes the machine to reboot with the following command:
  fatback -o . -a /dev/da2

Seems usb + storage is still not stable.

>How-To-Repeat:
Setup a freebsd6.0 i386 system.
Download & compile fatback.
Run it with a flashcards main device (/dev/da2).

>Fix:
Don't use fatback? =)
