Subject: Init hangs

Hi,

my kernel hangs by initializing the system. My target is mpc8270-based. I use ELDK 3.0 and mount my root-fs over nfs.
Denx-kernel 2.4.25.

I added some printk's in the function "static int init(void * unused)" of  linux/init/main.c to see what happens.

It seems like it hangs in "run_init_process("/sbin/init");" or the /sbin/init - file does not work.
Sometimes the message "INIT: version 2.84 booting" is showed. And after printing this message it hangs, too.
But the most times it looks like above.

Any ideas?
Thanks in advance

Marco
