Ravi, (may I call you Ravi?)
you've done this several times now.

Please understand that a printk without a "\n" termination
can be continued by subsequent printks.

When that happens, you should use printk(KERN_CONT... or
pr_cont(... to continue the previous message, not give a
new error level to the continuation.

cheers, Joe
