Hi,

I hit a kernel panic running a fresh -CURRENT today. This machine is my home NFS
server and it exports src and obj to a bunch of other machines. During an
installkernel on one of the other machines (using the src and obj exports from
the NFS server) the NFS server kernel paniced.

I took a quick photo of the stack backtrace, since I didn't have time to
investigate further (but I haven't rebooted the machine yet, it's still
sitting at the db> prompt:

Any ideas?
