Hi!

JFFS2 has known bug in GC leading to -ENOSPC upon file removal. Time
ago I've sent a patch with detailed explanations of what is going on.
Probably your case is the same.

Here is the patch
http://lists.infradead.org/pipermail/linux-mtd/2007-December/020091.html
(though infradead mailing list archive is missing most of messages
from this thread)

And here are some details
