124: On very high system load, an audio interrupt may occur while the
125: audio process is filling audio ring buffers. This triggers bogus

127: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=audio&sektion=4">audio(4)</a>

1.4 sthen 166: Restricting translation rules to protocols that are specific to the IP version
167: in use, is an effective workaround until the patch can be installed. As an
