It is still the question: my yaffs partition can't work at the second booting.

	At the first booting, I can see lots of information, such as "page 1828 in gc has no object: 0 0 0 ".

	I have taked an experiment: 
	1. Changed  the "gcOk = yaffs_GarbageCollectBlock(dev, block);" to "gcOk = YAFFS_OK;", 
in yaffs_CheckGarbageCollection of yaffs_guts.c,
	2. re-burn the yaffs image
	3. boot the system: it is ok
	4. reboot the system: it is ok too.

	Does yaffs_GarbageCollectBlock have some mistakes?
