You're probably right. I found several posts on the linux-kernel list
involving problems with write barrier support in combination with SATA
and ext3 . So I tried:

# mkfs -t ext3 /dev/md/0
# mount -o barrier=1 /dev/md/0 /mnt
# cp -a $src /mnt
# umount /mnt

And indeed, umount hangs now as well.
So it seems to be a linux-kernel issue after all...
    

Can you please try 2.6.17-rc5?

Great! 2.6.17_rc5 fixed this is issue. For Reiser4 as well as Ext3 (with barrier=1).

Many Thanks!
