Definitely not ruling it out, it's just different behavior than I've seen before. Regardless, I'll keep the ASR in mind as a possible source of the problem.

Try enabling LLDP or CDP and see if you can see anything.

Try looking on the "show int ten... accounting" counters to see if
either side receives what the other side claims to be sending.

The link might be good, but the IP layer might be confused...   or 
one side might be sending ok, but not receiving anything.

Counters good.
