You still need to enable them. The "=_" in the lines above indicate that they are disabled. E.g. to enable all r8152.c related debug messages prefixed with the function name: echo 'file r8152.c +fp' >/sys/kernel/debug/dynamic_debug/control See https://www.kernel.org/doc/Documentation/admin-guide/dynamic-debug-howto.rst for more info on the dynamic debug feature.
