problems with ramdisk (RAMDISK: Compressed image found at block 0 )

[Andreani Luca]

Hello list,

I'm developing a system based on the Motorola Sandpoint III with HardHat
linux 2.0.
Till now I used the nfs on my pc without any problems.
Now I need to use a ramdisk, I created it but it doesn't start and the
booting process is interrupted.
Below you can find the output from my console. Any idea?

Thanks

Luca Andreani
