Dear OtavioOtavio,

Ummm.. I guess you have a login or any other way to access a shell on
your board? You can (and should) manually check which filesystems are
mounted, and mount anything that may be missing.

This is harmless - just an indication that  your  way  to  build  the
ramdisk image is more or less broken.

To me this seems pretty much overkill for a ramdisk  of  an  embedded
system;  have  a  look  how  we  do this in our Simple Embedded Linux
Framework, see ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/

Fix the the build process for your ramdisk image.

I used to be indecisive, now I'm not sure.
