You should be able to boot from the fallback image.
I had this issue once, and the error message was "can't find root
filesystem in 30 seconds"; what I did for recovering was:
reboot from fallback image
add to /etc/mkinitcpio.conf MODULES="ext4"
mkinitcpio -c /etc/mkinitcpio.conf -g /boot/kernel26.img
reboot from the new image
since I heard that new kernel had worse performance for ext4 than
the previous one, and my / was ext4.
You should also read the mkinitcpio wiki page for more info.
