jffs2, NAND flash, which kernel

[JUPE Peter Jungreuthmayer]

Hi list,

I am relatively new to linux and jffs2 so please forgive me for my lack
of knowledge. 

I work with the SMDK2410 evaluation board  with Samsung S3C2410 ARM
processor and K9S1208 SmartMedia Card (= 64MB NAND flash).
Till now I used a 2.4.18 kernel with modifications for the SMDK from
MIZI research and  tried to use jffs2 on an 8MB NAND flash partition.
For a while I thought everthing is ok ( I can  mount and create and read
small test files) but then I encountered problems when I write a file
which crosses an block boundary (erase size is 16kB):

e.g.
# cp ./touchtest  /tmp/jffs2/
ARGH. About to write node to 0x00208760 on flash, but there's data
already ther:

Searching the archive I often saw the hint: "use a more recent kernel",
so my question:

 Which kernel version would you at least suggest for my configuration?

I would like to change only as little as possible because all in all my
system works quite fine and to many new things in one step means a lot
of sources of confusion.

Thanks in advance

Peter
