Hello,

I formatted a ssd with the following procedure:

gpart create -s gpt ad0
gpart add -t freebsd-boot -l sboot -s 64K ad0
gpart bootcode -b /mnt/boot/pmbr -p /mnt/boot/gptboot -i 1 ad0
gpart add -t freebsd-ufs -l sroot -b 2048 -s 1G ad0
gpart add -t freebsd-ufs -l svar -s 1G ad0
gpart add -t freebsd-ufs -l susr ad0

newfs -b 32768 -f 4096 -L root /dev/ad0p2
newfs -U -b 32768 -f 4096 -L var /dev/ad0p3
newfs -U -b 32768 -f 4096 -L usr /dev/ad0p4

After installing FreeBSD 8.2 the system (a soekris net5501) hangs on
boot with "gptboot: invalid GPT backup header" . I'm not sure if this
is a hardware problem or if I make a mistake during the setup.

What is the cause of the error message?

Many thanks
Matthias
