I'm not using DSA in my application, so I cannot test or replicate
what you were observing. It would be great if we could work together

Seen from my point of view, your patch is a regression. But perhaps my
patch set is a regression for you? Catch 22...

Would you be able to identify which patch broke your DSA behaviour?
Was it one of mine? Perhaps we can start from there.
