I tried with this init script,but kernel is hanging without any message.. I changed it a bit as below, to see if it reads the init script
#!/bin/sh /bin/echo "Entering Init script"
Init isn't allowed to exit. That's probably why you're seeing the panic. Try starting a shell after the /bin/echo, or just using /bin/sh as init.
with this changes,I am expect to get print message "Entering Init script" after cramfs is mounted,but I am getting panic message which is attached below.
Probably because the system panics before the stdout buffers make it to the console. Regards, Kristof
