All right, that was my understanding of the entire discussion -- an
accelerator dying mid-way and what will IMA do about that.

But as we fallback to early allocated shash, which is not USB yet,
then there is no problem.
ahash itself does not bring any other additional problem than shash
itself. They are compiled builtin together.

Sure, I understood that. But what will happen if the ahash accelerator
stops working mid-flight, will IMA also go bonkers or is there some
graceful stop?

shash fallback will be used.

Ah, thank you for clearing this!
