I have a 4.5-RELEASE-p2 box that is my Firewall/NAT/NFS server. As a NFS client I have a RH7.2 linux box. When I do massive NFS writes to my FBSD (from RH7.2 box), I get a panic. I've attached the info I got from my debug kernel. If there is more info you need, just ask (this is all the FBSD faq said to include).
