Ah, Martin, would it be possible to check if same issue appears with
current sftp module if you remove cache_read module from stream-filters?

cache_block/read and prefetch seem to overlap on functionality and not
sure if cache-module is usable on cases where fast_seek is enabled (it's
the case where prefetch is refusing to load and cache goes to
cache_read/cache_block module to my understanding).
