However, running the identical command:
/lib/udev/bcache-register /dev/md0
by hand a short while later from within the initramfs prompts works..
This sounds like the error I reported back in July:
http://article.gmane.org/gmane.linux.kernel.bcache.devel/2594
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.
