            Bug ID: 217434
           Summary: Raspberry Pi sound: locks when running make in any
                    ports directory
           Product: Base System

Quoting from bug 213687

Actually, I can reproduce the error as soon as sound is playing and at the =
same
time I launch "make" in some random /usr/port/*/*/ directory. After a few
seconds of compilation, I get the channel dead error.

I guess IO intensive operations make the sound driver crash. Output with sy=
sctl
hw.snd.verbose=3D4
