sounds like broken NIC.
transmit errors or dropped packages?
you can flood-ping the other node, also with larger packet size,
both directions? still no packet loss?
if you are sure that the network link between those nodes is ok,
try "drbdadm disconnect all; sleep 15; drbdadm connect all"
if that still does not help, I don't know...
