Why panic when run /bin/init?

hello all,
I have added a lcd device driver into my kernel,but when it run at /bin/init it panic . If I note the /bin/init in main.c,it works well(i add
/proc filesystem manualy).Sometimes it can execute /bin/init in main.c(such as
i reduce some code in my driver).
I use HHL2.2.14 & MPC850 & NFS root files.
Who can help me? thx.

Dross Chou.
