On PPC it is possible to build a FS while using a 4k PAGE_SIZE kernel then boot into a 64K PAGE_SIZE kernel. Presently open_ctree fails in an endless loop and hangs the machine in this situation. My debugging has show this Sector size < Page size to be a non trivial situation and a graceful exit from the situation would be nice for the time being.
