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?
