Ok, this was  quite easy.

I did not find many differnces:

include/mtd/mtd-abi.h  -- different size for oob fields (which may be the issue)
fs-fs-writeback.c  -- different strategy for locking
fs/mpage.c  -- "It seems that there is a IO coherent bug in generic_file_mmap()"
fs/yaffs/*  -- about 50% of the files differ

Here I did not have CONFIG_MTD_SW_HM_ECC set and none of the VERIFY options

Now it *appears* to work. There are still some strange messages like "Freechunks verification failure" but I did not do a flash_eraseall - I just tried to continue to use the file system created with the broken yaffs2.

I have also applied your LCD-movement and DMA priority patches. At least they don't make a problem :)

So I will do more testing now. But I think we are mostly done with the most important fixes and have at least a complete system (keyboard, power management, Debian stable, idea for minifs, ...).

BR,
Nikolaus
