Superfluous RAID1 Member

[n43w79]

Hi,
Testing FAI v3.4.7 install for Debian Squeeze.
I am seeing the following on everything start up just before grub menu:
error: superfluous RAID member (2 found).
Google search suggests that this seems to be a Debian bug. I moved swap 
partition to the end but that didn't help! Is there a workaround for FAI?
Many thanks! Kwon
