Dear all,
I have a module that uses pr_debug at init.
Although the module is successfully loaded, the message appears
neither in dmesg, nor at the console. I tried toprint a 8 to
/proc/sys/kernel/printk but that does not change anything.
Any hint would be warmly appreciated.
Thanks!
Sébastien
Do you have the relevant DEBUG macros activated in your kernel's configuration?

If not, activate them. Or if in a pinch, switch to using pr_alert() for development.
