A while back, I posted an inquiry about lockup of the NFS daemons on a
4/280 running 4.0.3.  This lockup seemed to be provoked by an IBM RS/6000
that was writing into one of the 280's filesystems.  The NFS Jumbo Patch
did not cure the problem.

I subsequently learned of a patch known as "nfs_dw", a changed ufs_bmap.o
module, which fixes a problem with nfsd hanging on a memory page that
never gets unlocked due to a bug.  This information was provided by Hal
Stern of Sun (halstern@sun.com).
