I am able to read my printk messages in the kernel buffer only after 
unloading the module..
Is there some reason or configuration behind this.

I used a simple kernel module with only init and exit functions, and 
after loading the module i cannot see the message printed by the 
"module_init" function in the output given by "dmesg -c" I can see them 
only after i unload the module.

i wait for around 15-20 seconds for the init message but it only shows 
up on removing the module.
