Oops, sorry.. I just tried that now but it doesn't improve things :(

I am writing directly to /dev/ad10 but stressing /dev/ad14 (sudo tar -cf /dev/null /local0)

It is interesting also that if I have md5's soaking up CPU then it's much less likely to start streaming properly and generally bombs out straight away. If I start it streaming and then start md5 it stays running... (even if it's rtprio'd)
