Pascal 
I'm trying to set up a TFTP/NFS according to various totos I found on the
web.
My problem is that the system hangs after the "booting the kernel" message
(see below).
The TUX image is displayed on the mini2440 screen and the 4 leds turn on,
but then nothing happens on the display (except that the screen is cleared
after a few minutes) nor on the terminal.
Is it a kernel problem or is it linked to the root fs on the NFS share ?
I've tried different root fs with same results.
Here is the environment :
