I finally got a riscv setup recreating this, and I am not sure how you're getting a "completion polled" here. I find that the polling from here progresses the request state to IDLE, so the timeout handler moves on to aborting because it's expecting COMPLETED. The driver should not be doing that, so I'll fix that up while also investigating why the interrupt isn't retriggering as expected.
