We had the very same issue with a 3750-X-stack and another 15 something
version two years ago. It's a horror scenario if you were planning a
"hitless rolling stack upgrade" and end up with a completely crashing
stack. :(

We went through TAC and finally got the box replaced. I have no
knowledge of any other solution.
