I am using journalctl -kf or journalctl -k
to see kernel log messages.

However, messages of "pr_debug" are not shown by this commands.

Is there some way to view pr_debug kernel messages with journalctl -k ?


regards,
Kevin

pr_debug messages is usually an empty macro, unless it is explicitly
enabled by using -DDEBUG in the Makefile for the specific file.

see: https://www.kernel.org/doc/local/pr_debug.txt
