HI all,

While trying to mount my mtd partition I am getting the below messages.
Once mounted everything seems to be working fine but not sure what these
messages mean.  Are these just the debug messages which I can
ignore,or something
which I need to look into.

I am using kernel 2.6.14 and Nand Flash.

mount -t jffs2 /dev/mtdblock10 /mnt/flash
