I would try running tcpdump and pinging 10.0.1.1 on your working machine.
You should see an ARP packet and the ICMP echo packets. Next, run it from
your 'broken' machine - do you see the ARP? If you don't, try running
tcpdump on 10.0.1.1 and generate your pings from the broken machine. Do you
see the ARP request?
Other things to try on the 'broken' machine -- a different IP address.
Static ARP entry for 10.0.1.1.
