Quite likely, although for whatever reason I didn't see any bcache 
register dmesgen. The retry-on-EBUSY approach sounds like it would 
resolve this, I'll need to have a go at testing it.

Ref the debian wheezy mdadm-initramfs bug, the udev settle fix would be 
required for any solution that makes the udev bcache-register hook wait. 
Seems like it has been fixed in jessie mdadm-3.3, but anyone using 
mdraid/bcache/lvm on wheezy will require some form of initramfs hacks.
