Hmm, this does sound weird, but I don't think the changes I made
recently to the AFS code should have anything to do with vnode free list
stuff. Were you able to tell what type of vnode it was that wasn't
free? (was it a UFS node, or an AFS node?)
[I just heard from Chad that it's also gotten that panic after running
for a while, not just at cache scan time. A vprint before the "free
vnode isn't" panic would sure help. Where's the right place to do
kernel mods these days?]
