Thanks, at first sight, this looks good. I don't see any obvious problem in the tracer code either.

If so, maybe we have a problem with this particular exception/interrupt branching directly to transfer_to_handler_full (i.e. the vanilla way) without being known from the Adeos pipeline, albeit it should?

I'll give it a try too on a mpc52xx.
