I have the same problem but only if I use amd(8), see here:

That works fine for me.
I posted the other day that I was now aware of the PR which describes
this. And true enough, non-automount NFS directories work fine.
Oddly, -current doesn't seem to have this problem. I've been testing
with 4.0_STABLE/i386 servers and 5.99.11/i386 and /macppc clients. The
i386 client has no trouble at all with automounted NFS file systems,
but it seems a little sluggish. It reports "nfs server foo not responding"
/ "nfs server foo is alive again" occasionally. Both client and server
are intel core2Duo 2.6GHz machines with 2GB RAM and "wm" gigabit ethernet,
although they're attached to a 100Mb switch.
The macppc client works, but has been exhibiting behavior I've never
seen before. Running a "cvs update" on the automounted source trees
mostly works, but I've been getting a "cvs client: refetching unpatchable
files" message that I've never seen before. It then displays the list
of files it's "U)pdating" and then sits there without exiting. I can
interrupt it with Ctrl-C, rerun the update and as long as it doesn't
do the "refetching..." thing, it terminates on its own.
The macppc client is a "G4 Digital Audio" 466MHz machine (gigabit
ethernet) with 256MB RAM and the server is a 2.8GHz pentium4 with 1GB
RAM and "bge" gigabit ethernet. Both attach to a Zonet gigabit switch.
Doing a 'build.sh release' (with appropriate obj/tools/dest/rel options)
and automounted NFS source trees works fine on either client (latest
source bugs notwithstanding ;).
