4.16. Is there anyway to reduce the number of LIDS violations that get reported on the console?

Yes. The syslog init script can be modified to start klogd with the "-c" option. This options sets the default level of system messages that get logged to the console. Any message with a value less than the value specified will appear on the console (see include/linux/kernel.h). For example:

klogd -c 4

Tells klogd to log all messages below level 4 will be logged to the console.

Another way to change the console log level is to modify the values in /proc/sys/kernel/printk. View the documentation provided in /usr/src/linux/Documentation/sysctl/kernel.txt for more information.
