Any clue ?
You only need to mount with space_cache once, and after that it's "sticky". What's probably happening is that you're mounting with space_cache, which rebuilds the cache. Then, if you reboot before it's finished rebuilding the cache, the cache isn't complete, and (I think) it causes the above message -- which is harmless. The same applies to the inode cache options. Try mounting with clear_cache *once*, then remounting with space_cache,inode_cache *once*, and waiting for it to finish rebuilding the cache. Finally, remove all mention of the caches from your fstab and kernel command line before you next mount the FS.
