It sounds a bit like loadbalancing with one broken link...
Have you verified, for example with acl counters at both sides of the link, in which direction the
packets are dropped?
As the customer has changed the devices, does the ASR uses a MAC starting with 4 or 6?
My only idea at the moment is to generate load on the link with a udp traffic generator which
does not work end to end and let them check where the traffic dies within their network.
