A friend has NetBSD-current-May15 set up with two Soundblaster Pros
for full-duplex audio.  His particular application continuously reads
from /dev/audio, does FFTs on the input, and (usually) copies this
directly to /dev/audio2.  This is all on a 386/25 w/387.

While this is happening, he gets "DMA x not finished" messages on the
console every minute or two.  Interestingly, the audio sounds fine
except for some slight gaps in the first few samples sent out.

Various tweaking with buffer sizes, and low & high water mark (for the
playing audio board), makes no difference.

Any idea what could be causing this?
