https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230370 Bug ID: 230370 Summary: [sound] Panic at sound mono recode on mips Product: Base System Version: CURRENT Hardware: mips OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: yamori813@yahoo.co.jp I work on AR7161(mips big endian) with USB device. I make simple recode command that is 44.1kHz mono recoding. I do this command soon happen panic. I change recoding to stereo then no problem.
