Then loading passes to login:
Ubuntu 14.04.1 LTS ubuntu tty1
ubuntu login:

But, if change /etc/mdadm/mdadm.conf (/dev/md/0 to /dev/md0 and /dev/md/1 to /dev/md1)

from:
ARRAY /dev/md/0 metadata=1.2 UUID=8f0090f4:8058b740:de4ea3e4:d197046c name=ubuntu:0
ARRAY /dev/md/1 metadata=1.2 UUID=039ff78d:03ed555f:2b050a37:996683f2 name=ubuntu:1

to:
ARRAY /dev/md0 metadata=1.2 UUID=8f0090f4:8058b740:de4ea3e4:d197046c name=ubuntu:0
ARRAY /dev/md1 metadata=1.2 UUID=039ff78d:03ed555f:2b050a37:996683f2 name=ubuntu:1

and run:
update-initramfs -u -k all
then boot loading passes to login:
Ubuntu 14.04.1 LTS ubuntu tty1
ubuntu login:

And after return lines
ARRAY /dev/md/0 metadata=1.2 UUID=8f0090f4:8058b740:de4ea3e4:d197046c name=ubuntu:0
ARRAY /dev/md/1 metadata=1.2 UUID=039ff78d:03ed555f:2b050a37:996683f2 name=ubuntu:1
to config file /etc/mdadm/mdadm.conf, then boot process stop at "(initramfs)".
