problem with latest mtd-cvs

[Zoltan Sogor]

Hi Artem!

We try to use the latest mtd and nandsim. We are using 2.6.12.3 kernel
and the latest cvs version of mtd. Nandsim is enabled with default
parameters (0x98,0x39,0xff,0xff).

We build a small image which contains some data (/bin, /sbin and mtd
source).
mkfs.jffs2 -n -p -e8KiB -r image_src -o testimg.jffs2

I load the nandsim module, erase it and write the image.

modprobe nandsim
flash_eraseall -j  /dev/mtd0c
nandwrite -p /dev/mtd0c testimg.jffs2

I get the following messages on my console during the mount process:

It workes fine with mtd from July 26. Mtd snapshot from Aug 1 is wrong.

I send the log to you in private.
