Thanks for the suggestion. With my computer happily running Sid, the magic sysreq key combinations appear to work, but I didn't notice any response to the magic sysreq key combinations when a MIDI-related lock-up occurred.
So I'm still in search of some steps to debugging a full lock-up when MIDI files are being played in combination with heavy disk activity.
