I think I have fixed the problem. For some reason the altstep as_Media_mgw in as_handover sets the norepeat flag. This allows as_handover to exit early. I think the problem was not visible before, but gerrit #19954 https://gerrit.osmocom.org/c/osmo-bsc/+/19954 changed the order of the IPACC/MDCX negotiation so I think that triggered the problem.

What happens is that after the IPACC MDCX is sent by the BSC as_handover exists and so there is never an answer to the MDCX, this eventually leads to a timeout.

I have removed the norepeat flag now and then the testcase is fine again.
