Explanation

Messages output by the driver are shown below in the order of severity.

There are three levels of severity.

Level of importance	Descriptions	facility.level
PANIC	This message is displayed when an event that will stop the system is detected.	kern.notice
WARNING	This message is output when an abnormal event is detected. It will not always result in an error.	kern.warning
NOTICE	This message is output to record driver operation and the like.	kern.notice

facility.level is the priority of a message passed from the GDS driver to syslogd(1M). The output destinations of messages are defined in the /etc/syslog.conf configuration file of syslogd(1M) and can be changed by modifying the definitions in /etc/syslog.conf. For details, see the description about syslog.conf(4) in this manual.
