I simplified the config a bit for better debugging. It is one USB stick now.

/dev/sda is the debian system that I boot from and chroot and debootstrap.

I do this process on the ML110G7, the resulting USB stick will boot on
Z600 system but not on the sytem that I created it on the ML110G7.

I tested the same config without using mdadm and the sytem booted up
just fine, so something goes wrong with mdadm grub and/or the machine.

These are my steps:

dd if=/dev/zero of=/dev/sdb bs=4M oflag=direct &

/sbin/parted --script /dev/sdb \
mklabel msdos \
mkpart primary 8M 100% \
toggle 1 boot \
print
