Hello,

Bitvisor crashes hosting Ubuntu. Error message:
BUG: unable to handle kernel NULL pointer dereference at (null)
Screenshot: http://78.46.181.215/temp/P1040508.JPG

Steps to reproduce:

# Download or create an USB drive ("sdb")
a) Download image:
     wget http://78.46.181.215/temp/image-usb-drive
     dd if=image-usb-drive of=/dev/sdb

b) Create:
     parted -s /dev/sdb mklabel msdos
     parted -s /dev/sdb -- mkpart primary NTFS 1 -1
     mkfs.ntfs -Q /dev/sdb1
     mkdir -p /tmp/bitvisor-installer
     mount /dev/sdb1 /tmp/bitvisor-installer
     grub-install --root-directory=/tmp/bitvisor-installer /dev/sdb
     wget -O /tmp/bitvisor-installer/boot/grub/grub.cfg 
http://78.46.181.215/temp/grub.cfg
     UUID=`blkid /dev/sdb1 -o udev | grep ID_FS_UUID= | sed s/.*=//g`
     sed -i s/UUID_PLACEHOLDER/$UUID/g 
/tmp/bitvisor-installer/boot/grub/grub.cfg
UBUNTUURL="http://ftp.acc.umu.se/mirror/gnome.org/misc/ubuntu-gnome-remix/ubuntu-gnome-12.10-desktop-i386.iso"
     wget -O /tmp/bitvisor-installer/boot/ubuntu.iso $UBUNTUURL
     # wget http://78.46.181.215/temp/bitvisor.conf
     cp /path/to/bitvisor.elf /tmp/bitvisor-installer/boot
     cp /path/to/module1.bin /tmp/bitvisor-installer/boot
     cp /path/to/module2.bin /tmp/bitvisor-installer/boot
     umount /tmp/bitvisor-installer

# Boot from USB stick
Select "Bitvisor", password: test
Select "Ubuntu Live CD"

# Ubuntu starts, open a terminal
# Install or dump data to the encrypted area
sudo dd if=/dev/zero of=/dev/sda1

# The system crashes after ~10 minutes.

The  configuration files you will find: "/isoimage/bitvisor-1.3"

Thanks a lot
Sandy
