[hariharan veerappan]

Hi 
    TRY with YAFFS MODULE for linux 2.4.18 kernel

    compiled the yaffs with CONFIG_YAFFS_USE_OLD_MTD options using arm
linux gcc cross compiler 2.95.3 with kernel 2.4.18
the module insertion and mount operations are successful.

When i copy the file in the yaffs mounted directory, DMESG shows the
Bad block error a below,

**>>ecc error unfixed on chunk 4775:0
**>>Block 149 marked for retirement
**>>ecc error unfixed on chunk 4776:0
**>>Block 149 marked for retirement

when i keep on copying the file into mounted area, i end up 
with flash of total bad block

please advise to fix
