When this feature is active, gang headers may be larger than 512 bytes. The loader needs to be taught to cope with that. Try using the vdev ashift to pick the gang block header size. If the checksum fails, fall back to the old gang block header size. This is based on a patch by Paul Dagnelie, with testing, bug-fixing and some simplifications from me.
