<br>
I have a module that uses pr_debug at init.<br>
Although the module is successfully loaded, the message appears<br>
neither in dmesg, nor at the console. I tried toprint a 8 to<br>
/proc/sys/kernel/printk but that does not change anything.<br>
<br>
Any hint would be warmly appreciated.<br>
<br>
Thanks!<br>
