Lots of Empty Flash messages.

[Ram]

Hi,
   Have flashed a new filesystem onto my nand flash.

   I boot linux out of nand. I make a first file write from the filesystem.

   When i reboot my system i see messages like:
    Empty flash at 0x00b69e60 ends at 0x00b6a000

   Sometimes, i get quite a way of them.


   On some boots i get only a couple and the addresses keep on changing.

   I have made my jffs2 filesystem with erase block size = 0x20000.

   I dont know why i get these messages...


   I also get messages such as bad erase block found at XXXX.


  Could you please advice on why they appear how i can avoid such messages.
