8.6.8 Error messages on the console screen

In order to quiet on-screen error messages, the first place to check is /etc/init.d/klogd. Set KLOGD="-c 3" in this script and run /etc/init.d/klogd restart. An alternative method is to run dmesg -n3.

Here error levels mean:

• 0: KERN_EMERG, system is unusable

• 1: KERN_ALERT, action must be taken immediately

• 2: KERN_CRIT, critical conditions

• 3: KERN_ERR, error conditions

• 4: KERN_WARNING, warning conditions

• 5: KERN_NOTICE, normal but significant condition

• 6: KERN_INFO, informational

• 7: KERN_DEBUG, debug-level messages

If one particular useless error message bothers you a lot, consider making a trivial kernel patch like shutup-abit-bp6 (available in the examples subdirectory).

Another place to look may be /etc/syslog.conf; check to see whether any messages are logged to a console device.
