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?
Run ethereal and have a look at the network traffic. Check which
files get loaded and/or accessed. This might give you an idea.
But first check your memory map. Kernels crashing when entering user
space are often an indication of illegal memory maps. See
http://www.denx.de/twiki/bin/view/PPCEmbedded/Kernel#Section_10.2.

How much net work could a network work, if a network could net work?

Hi Wolfgang,
thanks for your reply.

i started ethereal and saw that the NFS read calls from target to host, are answered with two IP "fragmented IP protocols" by the host,
followed by a NFS read reply [Unreassembled Packet] by the host, too. And that goes on and on until the connection is dead.
I am not sure whether the fragmentation of ip in two packets is correct? There is no additional traffic it is "only" mounting and using rootfs over NFS.
Can you help me ?
Thanks
Marco
