Well, I took bspisak's suggestion and did the same with my system (3.5.0-21), and so far it's stayed running for 18 continuous days, at least 10 days beyond the longest it had ever stayed running prior to that.
At first I thought the experiment wasn't successful, but quickly realized that the crashes behaved differently, and were in fact associated with running timidity. During this current 18-day run, I refrained from using timidity. I'll accept that as a small price to pay for stability.
