Hi Alexandros,

Well, it seems good, the freerunner regonizes the card and loads the kernel.
The kernel panic is as expected, there is just a kernel on the card and no distro yet.
Could you try  to install the root files system from [2] ?
After you installed it make sure to install the kernel in /boot as uImage-GTA02.bin
and add the /boot/append-GTA02.
(you could make a tar file before installing the rootfs)

in cut and paste style:
mkdir /tmp/mpt
mount /dev/sde1 /tmp/mpt
cd /tmp/mpt
tar -czf /tmp/old_boot.tgz ./boot
tar -xzvpf /the/downloaded/qtmoko-debian-v31.tar.gz
tar -xzvpf /tmp/old_boot.tgz
cd /
umount /tmp/mpt
eject /dev/sde

put the card in the freerunner and boot using qi
That should give you a working distro.
Please let us know any success/failure!

Kind regards,
Ed
