2.1.76 does no longer update arp entries correctly and looses parts of its
connectivity after a while (used in production environment with routing
etc etc). I think I saw something similar with 2.1.74:

Dec 24 10:21:15 deborah kernel: arp_unres_size=130
Dec 24 10:24:52 deborah kernel: arp_unres_size=130

etc... Some other interesting fragments of the log:
