https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217434 Bug ID: 217434 Summary: Raspberry Pi sound: locks when running make in any ports directory Product: Base System Version: CURRENT Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: gonzo@FreeBSD.org 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 ...
