I had a fun bug while building a smartwatch app that was caused by the sample rate of the accelerometer increasing when the device heated up. I had code that was performing machine learning on the accelerometer data, which would mysteriously get less accurate during prolonged operation. It turned out that we gathered most of our training data during shorter runs when the device was cool, and when the device heated up during extended use, it changed the frequencies of the recorded signals enough to throw off our model.

I've also used a logic analyzer to debug communications protocols quite a few times in my career, and I've grown to rather like that sort of work, tedious as it may be.

Just this week I built a VFS using FUSE and managed to kernel panic my Mac a half-dozen times. Very fun debugging times.
