Problems about init.

Tue Jul 24 08:11:47 UTC 2007

First , I would apologize because it may not be the problems about
busybox, however, I can not found another place for help.

Please take a look at my kernel bootling log, from the tail, you can
find that there were no output(but serial seems OK, you can see that I
have typed some chars and there have echo), it's so strange.

the kernel was boot from the nfsroot(same problem when boot from the flash),
and the boot cmd line is:
root=/dev/nfs rw nfsroot=192.168.35.105:/xxxx/fs
ip=192.168.35.107:192.168.35.105:192.168.35.1:255.255.255.0::eth0:off
rootfstype=jffs2 init=/etc/preinit noinitrd console=ttyS0,115200n8

Any ideas?
======
script etc/preinit
[root at sync fs]# cat etc/preinit
#!/bin/sh
echo "preinit start"

export PATH=/bin:/sbin:/usr/bin:/usr/sbin
exec /sbin/init
