That sounds like issues with multicast/broadcast receive on the host
(A). Pinging A->B allows (B) to update its ARP table without (A) having
to receive broadcast arp who-has request and that 2 minutes would be a
timeout for the ARP cache.

What card and driver (including version) are you using on (A)?
