I should be able to try get it to happen again tomorrow (I managed
to trigger the panic on my work computer only so far). The offending
ffplay4 -hide_banner -showmode waves -f oss /dev/audio

slower that the driver was providing it (because of the recording
rate mismatch in our oss which you have kindly fixed).
