I found what caused it. I had jackd running with set_rtlimits to set
RT priority. When I started ecasound I was in a hurry and loaded
realtime-lsm so I wouldn't have to edit /etc/set_rtlimits.conf and type
in a long command line to use set_rtlimits.
The kernel didn't like using two methods of setting RT priority at the
same time. With just realtime-lsm it works fine.
