Hi, Philipp,
I've found your answer too late. Thanks for the info(I learned something
about the early_prink from the book). 
Actually, shortly after I sent my question, I learned how to make printk
appear in the console (not in the dmesg buffer) and was using it.
(I added the line "kernel.prink = 5 4 1 7" in the /etc/sysctl.conf file.  
So I've set the default console log level to 5 making default printk appear
in the console.)
