Hi Charles,


Thanks for your time. I have test the newest code, it still failed :(.

some nandsim parameter and fsx's seed can trigger failure easily. For example,

modprobe nandsim first_id_byte=0x20 second_id_byte=0xac
third_id_byte=0x00 fourth_id_byte=0x25
modprobe mtdblock
mount -t yaffs2 /dev/mtdblock0 /mnt/yaffs2
./fsx -N 100000 -S 1596 /mnt/yaffs2/testfsx

it will fail at 7xxxx operations.
