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.
