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 at sun.com).
