Not sure if this kind of level of detail is useful, but if you can think of a better explanation to put in the changelist, I can add it. I see the generation bit not flipping as a symptom, while the core problem is the hardware can't write to the descriptor. I felt the explanation was going into too much detail anyway, so I've reworded it a bit for v2. Let me know what you think. Thanks, Stefan.
