I suggest getting rid of the "devices=" bits.  You don't want or need

'bread failed' suggests that the array isn't assembled.
If you assemble the array after boot
  mdadm -As /dev/md3
can you then mount the filesystem:
  mount /dev/md3 /wherever
?

I suspect something is wrong with the initramfs that debian created
for you - there have been a lot of complaints about that lately.
