FYI, I compiled my kernel with your patch and I have had no panic since
then.  Note that my previous uptime was multiple tens of days and I
haven't done stress tests.  But anyway I think your massively parallel
arp -d/ping tests are far more significative than my box which only
communicates with a couple of settled machines.
