linux-2.0.32 + ben-inode.diff hangs on NFS

I'm running linux-2.0.32-1 + the ben-inode.diff on one of our machines.
Some processes start to hang in state `D' on NFS access.

There is no way to kill these processes. Strange thing is, I can access and
edit a lot of files on my NFS mounted homedir without problems but vi'ing
the script "checkfreemem" _always_ hangs.

$ ps aux | grep D

Seems they are stuck in wait_on_inode. So this is probably a bug in the
ben-inode.diff...
