When I upgrade to the 3.19.2 Kernel I get a deadlocked boot:

If you boot single user is it semi-responsive enough to sysrq+w [1]
and post the resulting dmesg?

My 3.18.6 works just fine.

What do you get for 'btrfs check <dev>' You either need to run this
from the initramfs (totally unmounted file system) or rescue media
with a decently recent btrfs progs.
