My crashes were after my NFS client had copied a few hundred MB as well.
Copying MP3 files, then doing simple commands locked it up.... This
sounds very similar....

My lockup sequence:
cd some dir on the NFS client
mkdir testfiles
cp <some data> testfiles
ln -s testfiles testfiles-1
rm testfiles-1
mv testfiles testfiles-1
ls testf*

It will usually hang here.... Sounds like a similar problem. Did you
get any messages on your console prior to lockup? Also, you might try
the ikd patch and print %eip (on the console).

Sounds about like mine but I have knfsd-1.2.2 (RH 6.0).
