Programming :: Writing To Console From Kernel Module

I'm currently doing a tutorial for writing kernel modules. Right now I'm still at the very beginning, i.e. writing my helloworld stuff.

But what I like to do now is to write stuff onto the console, and I don't get it. According to my tutorials I can print stuff on the console using the printk()-function as long as the priority-level of the macro used in printk() is lower than the console_loglevel (how can I find that value out btw?).

But it doesn't work for me. Even if I use KERN_EMERG it still gets only logged, but not printed on the console and I thought KERN_EMERG get always printed...

Here's my code:

Everything works fine. But as soon as there are any blanks in mystring, e.g.

Code:

I always get

Code:

Why do I get this error and how can I insert string with blanks?
