What was the last version where this worked? Which soundfont do you have loaded? Are any other apps using the audio device at the time? What does /proc/asound/card0/voices look like? Try creating a MIDI file with only 8 notes, does that also cause the lockup? If this works then try 16, 32 etc until it locks up. Can the problem be reproduced on a UP kernel?
