Not sure if this is related or not, but I am seeing a 'boatload' of strange
proxy arp issues. Odd thing is that I dont have proxy arp enabled anywhere,
at least not knowingly.
Dear Mike:
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?
