initrd not bringing up mdadm raid

After a power outage my server wouldnt boot up, upon further investigation the raid arrays are not being brought up during initrd, the drives and arrays are healthy raid1, and I can bring them up manually from the ramfs which I am dropped too, the output from dmesg is here:

My grub config as follows

# (0) Arch Linux
title  Arch Linux  [/boot/vmlinuz26-lts]
root   (hd0,0)
#kernel /vmlinuz26-lts root=/dev/md3 ro printk.time=y
kernel /vmlinuz26-lts root=/dev/md3 footfstype=ext4 ro md=3,/dev/sda3,/dev/sdb3 md=1,/dev/sda1,/dev/sdb1 md=4,/dev/sda4,/dev/sdb4 md=2,/dev/sda2,/dev/sdb2 printk.time=y
initrd /kernel26-lts.img

My mdadm config did have the arrays defined, I then tried clearing it and rebuilding initfs image but that didnt help. The arrays being brought up as /dev/md12{4,5,6,7} which dont seem to be brought up correctly.

Any ideas?
