Hi slsnios,

There are many possible causes.
First, make sure you don't have the broken cramfs code. See:

http://forum.niosforum.com/forum/index.php?showtopic=2383&hl=cramfs)
Once you're sure your cramfs code is clean, you might want to enable jffs2/cramfs support in
u-boot. This will allow you to list and load jffs2/cramfs files into ram and view some file system
information -- it's a good way to ensure you have a clean filesystem image _before_ you boot
the kernel.
And, of course, double-check your kernel configuration to ensure you have cramfs support
enabled ;-)
