Well, it shouldn't be related, but sometimes things get tricky with locking
if it turns out that extra locking at one layer was masking a lack of
locking at another. Let's try to diagnose this one a bit more before
concluding that is the case, though. I take that the same problems don't
happen if you boot a vanilla version of the same rev of the kernel? What
command did you use to generate the list at the bottom of your e-mail?
the arp messages were a snippet from just arp -na. All of those IP
addresses are local to the box. I am just doing a cvsup to the same point
in time and am rebuilding the kernel.
Also odd, is that if I do a arp -nda it seems to want to delete more than it
should. Here is a snippet
It's concerning also that there is more than one entry for any particular IP
address. I'll have to go reread the ARP code. Confirming that this doesn't
happen with vanilla head is definitely the next step. I'll be fairly busy for
the next few days with things in Cambridge; if we can't rule out the inpcb
patches as the source of the problem, I'll defer committing them until next
week when I have a chance to work through this more.

After doing arp -nda, I am back to a very large arp cache again right away
