Then i have to change the do_write_oneword function to wait until erase is 
finshed ?

the difference is: cp rootfs.img /dev/mtd only uses:

MTD_write
MTD_do_write_buffer
and so on ...

and cp a file on the mounted image uses:

MTD do_write_buffer(): WRITE 0x0028641c(0xe0011985)
MTD do_write_oneword(): WRITE 0x0028641c(0xd5997a45)
MTD do_write_oneword(): software timeout
MTD do_write_oneword(): software timeout
MTD do_write_oneword(): software timeout
MTD do_write_oneword(): software timeout
Write of 45 bytes at 0x0004641c failed. returned -5, retlen 36

I have done this with a 2.6.8-rc3 there was the same problem, because of that 
i haved used the snapshot of yesterday.
