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? https://www.kernel.org/doc/local/pr_debug.txt http://elinux.org/Debugging_by_printing If not, activate them. Or if in a pinch, switch to using pr_alert() for development. Luis
