I re-introduced the change that I previously rolled back to get things
working, and then upgraded pfil.c to 1.34 and built a new kernel.  This
worked fine -- you've obviously corrected the problem.  :)

About the NFS hang:

Noted - but I haven't been able to get into DDB.  I though Ctrl-Alt-Esc
in the first console (the Ctrl-Alt-F1 one) should do it, but it doesn't.

Not much.  Server:

nfs_server=YES and nfsd_flags="-n 16" in rc.conf.

Client:

nfs_client=YES in rc.conf, and "rw,bg,intr" as mount options.

Hm. Maybe I should change to a TCP mount, and see what happens...
