While I hit it fairly often, I can't reliably reproduce the crash, but
in limited testing this seems ok to me.
I've not hit the crash so far, nor seen any other negative side
effects over 5.14.

So for what that's worth:
Tested-by: John Stultz <john.stultz@linaro.org>

Caleb has better luck tripping this issue right away, so they can
hopefully provide a more assured response.
