Warning during GC, resulting in to Magic Bitmask Error for JFFS2.

I'm not sure printing this message is a brilliant idea, but it is
harmless. Deletion in JFFS2 means writing new deletion nodes, which also
require some space. Your filesystem is stuffed fully, and there is no
space to write. But since writes are *deletions*, JFFS2 uses the blicks
which are reserved for GC to write these deletion nodes. And it prints
the messages you've observed.

Surely you reboot your board uncleanly, i.e., without cleanly unmounting
it?
