Following up my own question:

I tried the audacity port, and to my surprise pressing on the record
button produced a panic.  Trying something simpler, I also get a panic
with

  aurecord -rate 44000 -file aiff -data AuFormatLinearSigned16MSB /tmp/rec

The panic is a page fault at pc 8:0xc0296177, which addr2line says is
generic_bcopy.

I'll look into this more tomorrow, but has anyone else experienced this?

I'm running 4.6, and the sound-related devices are:

pcm0: <VIA VT82C686A> port 0xe400-0xe403,0xe000-0xe003,0xdc00-0xdcff irq 11 at device 7.5 on pci0
pcm1: <Yamaha DS-1 (YMF724)> mem 0xdf000000-0xdf007fff irq 11 at device 10.0 on pci0

/dev/dsp is a link to dsp1 (ie I'm using the Yamaha rather than the VIA
motherboard sound).
