Didn't we have this for years? I cannot recall there was a difference to the
current behavior since 8.x or 7.x (or even 6.x).
kern.msgbuf includes messages sent with syslog, and if they dominate
then you might get empty dmesg output. By default it skips non-kernel
(or rather those messages which doesn't use BSD syslog format)
messages, and you can include them using dmesg -a.
