Can you send a full bootlog, or paste it somewhere accessible ? It's hard
to say what's with the information you've given.

Is this the latest yocto master ?

If you are seeing that message it typically means that the the
device that is being used as the root isn't ready (fixed by
rootwait/rootdelay) or isn't supported (i.e. NFS root without
the right ethernet device). Changing what init is, won't change
the result if either one of those is the case.
