... or when syslogd is configured to log to console :)

Extensive use of kernel printfs kills boxes that run serial consoles.

I'd prefer to see all logging in kernel done via log(9) and default
syslogd.conf configured to write kern.* to console. Those people, who run
serial consoles can remove this from their syslogd.conf.
